TRUTH 01
~30%
The hidden buffer
The industry-standard "fixed price" includes a 20-30% contingency padded into the rate, invisible to you, profit to them if the fixed-price IT project goes smoothly. You pay for risk you cannot see.
Fixed-price software development is the most-asked-for fixed-price engagement model. But it is also the most-failed one in software. The reason is almost never the price. It is the operating model around the price. Call it fixed-cost software development, fixed-bid software development, or fixed-budget software development; the label might change, but the failure pattern does not. Below are five truths every engineering leader has lived through. Unified leads with them because the antidotes are the entire reason this page exists.
TRUTH 01
~30%
The industry-standard "fixed price" includes a 20-30% contingency padded into the rate, invisible to you, profit to them if the fixed-price IT project goes smoothly. You pay for risk you cannot see.
TRUTH 02
67%
Two-thirds of fixed-price software projects end up with more billed via change orders than the original SOW. Change requests stop being a collaboration tool and become a billing model.
TRUTH 03
Sprint 8
When margin is squeezed, and the calendar is fixed, the variable that gets cut is quality. Testing collapses, docs disappear, the handover sprint becomes a heroics-driven release.
TRUTH 04
3 Wks
Without acceptance criteria written before the sprint, the last three weeks of every fixed-price software project become a Slack war over the definition of "done." Both sides lose.
TRUTH 05
0 wins
A penalty clause that says, "If anything goes wrong, the contractor has to pay" reads well in a procurement memo. In practice, when a vendor goes underwater, the project also goes underwater. There are no winners on a failing fixed price.
Every Unified fixed-price engagement model is built around antidotes to these five truths. An open-book buffer instead of a hidden one. A published Change Control Charter instead of a change-order revenue model. Embedded QA instead of quality-as-final-sprint. Acceptance criteria written before sprints, not after. And if we look at your project and the model is wrong, we say so in writing and recommend a Dedicated Pod or Staff Augmentation engagement instead. The rest of this page is the operating model that makes that possible.
Fixed price is a precision instrument. It works beautifully on the right outsourced software project and quietly destroys the wrong one. Below is the two-column qualifier we use in every discovery call. Before pricing, before signatures, before anyone gets emotionally invested. If you sit in the right column on most rows, fixed price is the right tool. If you sit in the left, we will recommend Dedicated Pod or Staff Augmentation instead, and we will tell you in the first 30 minutes.
FIXED PRICE, THE RIGHT TOOL
If you can say "yes" to most of the seven rows below, your fixed-price custom software development project is a strong candidate. We have shipped hundreds of these.
Stable scope. You can describe the end state in a requirements specification without saying, "and then we'll figure out X mid-project."
Mature problem. The product, customer, and workflow are well-understood. Not greenfield discovery.
Acceptance criteria possible. Each milestone has an observable, testable "done" state.
Reasonable horizon. 3 to 9 months end-to-end. Long enough to plan a fixed timeline, short enough to lock.
Independent build surface. Few third-party dependencies you cannot control or wait on.
Defined non-functional bar. Performance, security, compliance requirements documented upfront.
Decision-maker in the room. One product owner who can approve scope, milestones, and acceptance.
Typical Fits: Modernization. Re-Platform. Compliance Build. Enterprise Integration. Migration. MVP Rebuild.
FIXED PRICE, THE WRONG TOOL
If your project sits on the seven rows below, fixed price will hurt you. We will recommend a Dedicated Pod or Staff Augmentation model in the first 30 minutes.
Greenfield discovery. You're still finding product-market fit. The right product is unknown until you ship and learn.
Heavy R&D. AI experimentation, novel algorithms, evaluation-driven iteration. Outcomes cannot be pre-specified.
Pivots expected. Customer feedback, regulatory shifts, or competitive moves will force scope re-thinks mid-project.
Long horizon (over 12 months). Anything beyond a year is too long to lock; the world moves underneath you.
Third-party dependent. You're waiting on an enterprise partner's API, a vendor's release, a regulator's clarification.
Continuous evolution. The product is a platform that needs ongoing engineering capacity, not a project with a finish line.
No single product owner. Six stakeholders, no decision-maker. Fixed price assumes one voice.
Better Model: Dedicated Pod Or Staff Augmentation.
A fixed price needs a fixed scope. If you already have a detailed SOW, RFP, or requirements document, you do not need this. Send it; we return a fixed-price proposal in 5 business days. If you don't have one yet, the 2-week Discovery phase is how Unified produces a buildable artifact: a SOW detailed enough that nothing in the build phase is left to assumption, every project risk is identified, mitigated, and owned, and the effort estimation is accurate enough to underwrite a fixed-price proposal. Paid engagement. 100% credited against the fixed scope software project if you proceed. Yours to keep, shop, or hand to any vendor for outsourced software delivery if you don't.
FOR PROSPECTS WITHOUT A DETAILED SCOPE
DOMAIN IMMERSION
The BA, Solution Architect, and Tech Lead embed with your team for five working days of the discovery phase. Stakeholder interviews, current-state audit, technical archaeology on the existing codebase or systems, integration map, non-functional discovery.
SOLUTION & SOW
The squad converts week-one output into a project blueprint. Solution architecture diagram, defined scope, software project decomposition into milestones, acceptance criteria draft for each, risk register, milestone-paced fixed timeline, and the fixed price proposal itself.
THE THREE THINGS YOU WALK AWAY WITH
Whether or not you decide to engage Unified for the build, the deliverables the workshop produces are designed to do three things, structurally, every time. Each one is named, owned, and signed off before the SOW is delivered.
Every workflow, edge case, integration, and non-functional requirement is written down. The SOW carries a glossary; ambiguous nouns become defined terms. Acceptance criteria drafted before kickoff in Gherkin-style given / when / then.
The build phase becomes execution, not interpretation.
An open-book risk register with named owners on both sides. Each risk carries a likelihood, an impact, a mitigation path, a contingency plan, and a decision threshold. Assumptions are dated, with confirmation deadlines.
No risk goes silent. No surprise lands in week six.
The project estimate is broken down by milestone, by role, by week, using three-point PERT estimation and reference class forecasting against our 300+ project archive. Cross-checked by a senior architect outside the workshop.
The fixed price holds because the underlying estimate is real.
WORKSHOP INVESTMENT
Workshop fees are sized to your project's domain, integration topology, and team availability. 100% credited against the fixed-price project if you proceed. Yours to keep if you don't.
ENGAGEMENT DIRECTOR RESPONDS WITHIN 24 HOURS
Most fixed-price quotes are produced the same way: a salesperson looks at the deck, adds 30% to whatever feels right, and emails the number before the prospect cools down. The estimate is a marketing artifact, not an engineering one.
Unified does not work this way. Every fixed-price engagement model proposal is built on a disciplined, builder-led, science-of-software method that turns scope into a number we will stand behind in contract. We follow the same method whether you hire a fixed-price development team for a single build or hire software development on a fixed price across several projects a year.
The method, the principles, and the calibration loop are given below.
We quote based on ensuring project success and quality, not on getting the project.
THE ESTIMATION PRINCIPLE THAT GOVERNS EVERY UNIFIED FIXED PRICE PROPOSAL
PRINCIPLE 01
The Tech Lead and Solution Architect hold single point of accountability for every number on the proposal. Sales is not allowed to adjust them downward to win a deal. If the number is wrong, the architect who signed it owns the correction.
Industry default: Sales estimates by gut, builders inherit the consequences.
PRINCIPLE 02
Every work package gets best, likely, and worst estimates. PERT-weighted expected value. Standard deviation captured. A single number lies; a three-point estimate tells the truth about uncertainty.
Industry default: One number presented as a measurement.
PRINCIPLE 03
If a work package is bigger than a week, it is wrong. We decompose until every estimable unit fits inside a sprint. Big lumps hide risk. Small lumps surface it. The decomposition itself is the first quality gate.
Industry default: "build the dashboard, 4 weeks," with no visibility inside.
PRINCIPLE 04
Bottom-up estimates are always cross-checked against actuals from our archive of past similar projects. Reference class forecasting catches the systematic optimism that bottom-up estimation cannot see in itself.
Industry default: bottom-up only, with no calibration against history.
PRINCIPLE 05
The confidence interval lives on the proposal. The Cone of Uncertainty is named and explained. Where uncertainty is high (early discovery, novel integration), we say so. We do not paper over with a bigger buffer.
Industry default: a single point estimate with a hidden 30% pad.
PRINCIPLE 06
Testing, observability, security review, documentation, UAT support, and handover get their own line items with their own estimates. They are not assumed to be free, and they are not skipped at the end of the project to save margin.
Industry default: NFRs treated as overhead, cut first when calendar tightens.
PRINCIPLE 07
Every assumption baked into the estimate is logged in the Assumption Ledger with a confidence level, an owner, and a date by which it must be confirmed. Assumptions that fail before that date trigger a transparent re-estimate. No surprises in week eight.
Industry default: assumptions buried in the SOW prose, surfaced only when something breaks.
PRINCIPLE 08
Every estimate is logged at SOW lock. Actual hours are logged throughout delivery. Variance is computed at project close. Heuristics are recalibrated every quarter. Our estimates today are measurably more accurate than they were a year ago.
Industry default: estimate, forget, repeat. No learning loop.
ESTIMATE-TO-ACTUAL VARIANCE
7.4% average
Across the last 18 fixed-price projects, the average variance between the bottom-up estimate at SOW lock and the actual delivered hours.
ON-TIME DELIVERY
92%
Last 24 months. The estimate held because the method held. The remaining 8% triggered a Phase Exit Ramp or a Change Charter re-scope, never a silent overrun.
REFERENCE CLASS ARCHIVE
300+ projects
Past shipped engagements logged with actuals, used as the calibration set for every new estimate by domain, stack, and compliance envelope.
CALIBRATION CADENCE
Quarterly
Estimation heuristics reviewed and adjusted every 90 days. Senior architects own the calibration log. Variance trends published internally.
Every Unified fixed-price engagement runs on the same ten-instrument operating system, built for vendor accountability and risk transfer. Not best-effort. Not aspirational. Each one is written into the SOW or the MSA, with an owner, a cadence, and an artifact attached. The instruments exist because they are the antidotes to the five truths in section 01. They are also the reason our last 24-month on-time delivery rate is 92%.
INSTRUMENT 01
No fixed price without a detailed SOW. If you arrive with one, we lock it. If you don't, the 2-week Discovery Workshop produces it. Either way, scope is countersigned, acceptance criteria are written, and the proposal is built on a real estimate, not a vendor's gut.
INSTRUMENT 02
A signed scope-freeze ceremony at the end of the workshop. Every milestone has a named owner on both sides. The SOW becomes a single source of truth, referenced in every change request, every demo, every dispute.
INSTRUMENT 03
The 15% contingency line lives on the proposal and the invoice, not behind them. If we do not consume it, we credit half back at project close. If we consume past it, we eat the variance. Skin in the game, in writing.
INSTRUMENT 04
Every milestone has Gherkin-style "given / when / then" acceptance criteria signed off before the sprint starts, not negotiated after it ends. Removes 90% of the "is this done?" arguments that haunt fixed-price projects.
INSTRUMENT 05
Payment is triggered by your sign-off on the milestone's acceptance criteria, not by a calendar date. If we miss the criteria, the gate does not open. If we miss the date but pass the criteria, the gate still opens.
INSTRUMENT 06
A four-tier change-request protocol in the SOW. Some changes are free. Some come with a documented flex pool. Some are scope additions with a transparent quote. No more "everything is a change order" surprise.
INSTRUMENT 07
At the end of each phase, both sides have an exit ramp with no penalty, no claw-back, full handover. If we are wrong for each other, the worst case is "we wasted one phase," not "we lose six months."
INSTRUMENT 08
Test automation, regression coverage, performance benchmarks, security scans on every PR, from day one of the build, not the final sprint. Quality cannot be the variable when the calendar and the price are fixed.
INSTRUMENT 09
Every Friday. Working software. Not slides. Not "we're 60% done." If a demo cannot show the milestone moving, the milestone is not moving. Two consecutive misses triggers a no-fault exit ramp.
INSTRUMENT 10
All IP, source, configurations, infrastructure-as-code, runbooks, ADRs, and Glass Box AI Policy artifacts are assigned to your entity at signature. Code escrow available. No retained background IP. No derivatives clause.
Every Unified fixed price engagement runs through the same six phases. Each phase has a named owner, a calendar window, a deliverable artifact, and an Acceptance Gate that pays the next milestone. A Phase Exit Ramp opens at every gate. Either side can step off, no penalty. This is the lifecycle you would see in your SOW on signature day.
[5 DAYS, OR 2 WEEKS]
Two paths in. If you arrive with a detailed SOW, RFP, or requirements specification, we review it in 5 business days and return the proposal. If you don't, the 2-week Discovery Workshop produces the SOW from a senior squad of a BA, Solution Architect, and Tech Lead.
ACCEPTANCE GATE Signed SOW, fixed price proposal, milestone schedule
[1 week]
SOW Lock ceremony. Both sides countersign scope, milestones, acceptance criteria, Change Control Charter, and the Open-Book Buffer line. Pod composed and assigned.
ACCEPTANCE GATE Locked SOW, named pod, payment milestone 1 released
[2-4 weeks]
Architecture instantiated, environments provisioned, CI/CD wired, observability seeded, security baselines set. Embedded QA online from day one of code. First demo at end of phase.
ACCEPTANCE GATE Foundation demo, architecture sign-off, exit ramp open
[8-24 weeks]
Four to eight milestones, each with pre-written acceptance criteria. Weekly working-software demos. Change Control Charter governs all scope movement. Open-Book Buffer consumption tracked weekly.
ACCEPTANCE GATE Each milestone passes its acceptance criteria; payment released
[2-4 weeks]
Performance testing, security review, accessibility audit, user acceptance testing with your real customers. Bugs triaged by the acceptance criteria. Anything that violates a documented criterion is fixed under contract.
ACCEPTANCE GATE UAT sign-off, NFR targets met, security review clean
[1-2 weeks]
Runbooks, on-call playbooks, ADR set, observability tour, training sessions for your team. Open-Book Buffer reconciliation. If buffer was not consumed, 50% credited back. Final invoice. Clean project sign-off.
ACCEPTANCE GATE Final acceptance, project close, buffer credit issued
Most vendors hide the risk register in the buffer. Unified publishes it. Below are six risks that exist on every fixed-price project, the ones experienced engineering leaders ask about in the first call. For each, the instrument from the Operating System that owns it, and the outcome you can actually defend to your CFO. The risk register lives next to the SOW in your data room from day one.
The SOW reads well in the conference room. In sprint three, two sentences mean three different things to three different people.
Acceptance Criteria written before the sprint. Every milestone has Gherkin-style given/when/then criteria signed off before kickoff. The SOW carries a glossary; ambiguous nouns become defined terms. Workshop output enforced via SOW Lock.
INSTRUMENT 04 · ACCEPTANCE CRITERIA
Zero "is-it-done" disputes. Every milestone closes on a written, pre-signed standard. Your CFO sees an audit trail of what was promised vs. what was accepted.
Two-thirds of fixed-price projects end up billing more in change orders than the original SOW. Change becomes a billing model.
Change Control Charter, four-tier, published. Clarifications and styling tweaks are free. A flex pool covers ~10% of small scope movements. Net-new scope gets a transparent quote with a one-week turnaround. No more silent reclassification.
INSTRUMENT 06 · CHANGE CHARTER
Change orders below 8% of original SOW on the last 18 engagements. Industry benchmark is 60-80%. The Charter is auditable, line by line.
The standard industry buffer is 20-30%, baked into the rate, invisible to you. Profit to the vendor if the project goes smoothly.
Open-Book Buffer, 15%, shown on the invoice. The contingency line is a separate line item on the proposal and the invoice. Unconsumed buffer is reconciled at project close. 50% credited back to you. Consumed-past-buffer is on us.
INSTRUMENT 03 · OPEN-BOOK BUFFER
Visible price formation. Your CFO sees engineering, management, QA, PM, and buffer as separate lines. Auditable. Defensible. No "trust us" line items.
When margin is squeezed and the calendar is fixed, the variable cut is quality. Testing collapses. Docs disappear. The last sprint is heroics.
Embedded QA from sprint one. Test automation, regression coverage, perf benchmarks, security scans on every PR from day one of the build. QA capacity is a fixed line in the bill of materials. It cannot be quietly reallocated.
INSTRUMENT 08 · EMBEDDED QA
92% on-time delivery with full test coverage, last 24 months. Quality is a constraint, not a variable.
"Contractor pays if anything goes wrong" reads well in procurement. In practice, when a vendor goes underwater, your project goes with it.
Phase Exit Ramps, two-way, no penalty. At every Acceptance Gate, either side can step off. Worst case: one phase lost, full handover, runbooks and code yours. No hostage clauses. Combined with the Open-Book Buffer model.
INSTRUMENT 07 · EXIT RAMPS
Bounded downside. Your maximum exposure is one phase, not the whole project. Legal team has reviewed the clause; it is in plain language.
A vendor API change, a regulator's clarification, a partner's release schedule, and the calendar moves through no fault of either of us.
Risk register publishes third-party dependencies upfront. Each one named, with an owner on your side, with a slip-impact analysis. SOW carves out "external-dependency" milestones with a renegotiation trigger, not a billing trigger.
WORKSHOP DELIVERABLE · OPEN-BOOK
No third-party surprise. Your CFO sees the dependency map at SOW lock. Slips are renegotiated, not weaponized.
The Change Control Charter is the single most important document in a fixed price project. Most vendors hide it inside the MSA. We publish it on this page. Four tiers of change, three columns of governance: what it is, how it moves through the system, what it costs. The Charter lives in the SOW, not the email thread.
e.g. "Make the error message friendlier." "The accept button should be primary, not secondary." Edge case clarification that lives inside the existing acceptance criterion.
Captured as a clarification note on the milestone. Engineer makes the call in the next PR. No process overhead. No approval needed. No paper.
0$ Bundled into the milestone.
We assume some clarifications in every sprint.
e.g., "We need a dark-mode variant of the dashboard." "Add a CSV export to the report module." Small, well-scoped additions within the milestone's spirit.
EM logs against the flex pool. Confirmed in the next weekly demo. Pool is ~10% of milestone effort, sized at SOW lock. Visible to you in the Glass Box dashboard.
0$ from the flex pool
When the pool is exhausted, further Tier-02 items move to Tier 03 at transparent rates.
e.g. "We need a new integration with Stripe Connect." "Add a multi-tenant admin console." Net-new functionality outside the SOW's documented scope.
Change request raised on the form embedded in the dashboard. Costed within 5 business days. You approve or decline in writing. Approved scope is added with its own milestone, acceptance criteria, and payment trigger.
Transparent quote
Same blended rate as the original SOW. Buffer model applies. No partner-rate premium. No "we'll figure it out later."
e.g. "We're pivoting from a B2C to a B2B model." "The compliance regime just changed." Scope changes large enough to invalidate the SOW.
Triggers a one-week mini-workshop to re-scope. Existing SOW pauses; Phase Exit Ramp opens. Either side can step off. If we continue, a new SOW is issued. The original buffer reconciles at the pause point.
Re-priced
Honest re-quote based on new scope. Workshop fee for the re-scope is creditable against the new SOW.
Most vendors quote a single number with a 20-30% buffer baked in. Unified does it differently: every fixed-price proposal carries five named line items: engineering, EM and delivery, QA and DevOps, PM and BA, and an open-book buffer. The buffer is 15%, sits on the invoice, and reconciles at close. Below is the typical line composition for a six-month build. Your numbers will move, but the fixed price model’s structure does not.
ENGINEERING
50%
Senior+ FE/BE/AI engineers shipping product. Named, AI-augmented, locked on the engagement.
EM & DELIVERY
15%
Engineering Manager + Engagement Director. Sprint cadence, demos, steer-co, Glass Box reporting.
QA & DEVOPS
12%
Test automation, CI/CD, observability, security scans, performance benchmarks. Embedded from sprint one.
PM & BA
8%
Acceptance criteria authoring, change-request triage, stakeholder coordination, milestone governance.
OPEN-BOOK BUFFER
15%
Contingency, shown on the invoice. Unconsumed buffer reconciles 50% back to you. Over-buffer is on us.
Each use case below is a real engagement we have shipped through turnkey software development on a fixed-price SOW in the last 18 months. The pattern is the same: bounded scope, mature problem domain, defined non-functional bar. If your situation rhymes with one of these and your scope is detailed, we quote in 5 business days. If your scope still needs definition, the Discovery Workshop closes that gap.

Most fixed-price vendors are good at one thing: the sales cycle. Unified is built around software development with guaranteed delivery. Below are the four structural reasons our last 24 months of fixed-price engagements landed inside the SOW, inside the buffer, and on the calendar. None of these are marketing claims; each has a corresponding instrument in the Operating System (section 04) and the Risk Register (section 06).
REASON 01
1 in 4 fixed price inquiries turn down at the workshop end Workshop SOW yours to keep if FP is wrong Open-Book Buffer on the invoice, not behind it Change Charter published in the SOW, not the email thread
REASON 02
70% senior+ on every fixed-price pod Every developer with Cursor, Claude, Copilot in IDE Senior architect carried from workshop to handover 250+ engineers, top 10% of the talent market
REASON 03
92% on-time delivery, last 24 months 2 to 6% change orders, vs industry 60 to 80% Buffer consumption averaged 68% across last 18 projects 15+ years of fixed price engagements, 4.6 Clutch
REASON 04
4 to 6-hour overlap with US Eastern, every working day NYC-based Engagement Director on every steer-co Approximately 50% of US premium boutique rates ISO 27001, SOC 2 in progress, IP yours day 1
The conversation moves from your engineering steer-co to the finance committee to Legal. Below are the six questions every fixed-price engagement faces in that journey, and the clause from the Operating System that owns the answer. Each answer is in writing on signature day, not "best efforts."
Mitigation: A Phase Exit Ramp opens at every Acceptance Gate. Either side can step off with no penalty, no claw-back, full handover, runbooks, and code yours. Maximum exposure is one phase, not the whole project. Open-Book Buffer reconciles at the pause point.
Mitigation: The contingency line is a named line item on the proposal and the invoice, a 15% open-book buffer. Unconsumed buffer reconciles 50% back to you at close. Over-buffer is on us. Your CFO audits it line by line.
Mitigation: The Change Control Charter, published in the SOW, defines four tiers. Tier 01 (clarifications) is free. Tier 02 (flex pool, ~10% of milestone effort) is free until exhausted. Tier 03 (scope additions) is a transparent change request quoted at the same blended rate. Tier 04 (pivot) triggers re-scope.
Mitigation: QA + DevOps capacity is a fixed line in the bill of materials. Test automation, regression coverage, perf benchmarks, security scans run on every PR from sprint one, not bolted on at the end. Acceptance Gates cannot pass unless the quality-assurance bar is met.
Mitigation: You. All source code, infrastructure-as-code, prompts, eval suites, runbooks, ADRs, and Glass Box AI Policy artifacts get transferred to you, with full project ownership, at signature. Code escrow available on request. ISO 27001 certified. SOC 2 in progress.
Mitigation: Two consecutive missed weekly demos trigger a no-fault Phase Exit Ramp. Two consecutive missed Acceptance Gates trigger the same. Project management success is reviewed against the SOW, the buffer, and the charter, not against vendor-favorable interpretation. Quality SLA breach = no-fault exit.
No, not if you already have a detailed scope. If you arrive with a complete SOW, RFP, or requirements document, send it to us, and we return a fixed-price proposal in 5 business days. We'll review it for gaps and flag anything missing, but if the document is buildable as-is, you skip the workshop entirely. The workshop exists for the other case: prospects who have a vision, a deck, a Notion doc, or an investor narrative, but not yet a buildable artifact. In that case, the workshop is how Unified turns rough scope into a SOW with nothing left to assumption, every risk identified and owned, and an estimate accurate enough to underwrite a fixed price.
Workshop fees are sized to your project's domain, integration topology, and team availability. Senior squad of BA, Solution Architect, and Tech Lead for 10 working days. Paid upfront. 100% credited against the fixed-price project if it proceeds. Yours to keep if it does not: the SOW, the architecture diagram, the risk register, the milestone plan, the proposal. Request a workshop quote on the contact form below, and the Engagement Director returns an exact number within 48 hours of the fit call.
Then we say so in writing at the end of the workshop. The SOW is still yours. We will recommend a Dedicated Pod or Staff Augmentation model based on what we found. No build dollars were spent. We turn down roughly 1 in 4 fixed-price inquiries at the end of the workshop, usually because discovery, R&D, or pivots are part of the journey. Saying no is a feature of this model.
The industry standard is a 20-30% buffer baked invisibly into the rate. Profit to the vendor if the project goes smoothly. Unified shows the buffer as a separate 15% line item on the proposal and the invoice. If we do not consume it, we credit 50% back at close. If we consume past it, we eat the variance. The buffer is auditable. Your CFO can run a line item against it in any monthly review.
12-36 weeks end-to-end is the sweet spot. Below 12 weeks, the workshop overhead is a higher proportion of the project (we will sometimes pre-discount the workshop in that case). Above 36 weeks, the world moves underneath you. We will usually recommend either splitting into two SOWs back-to-back or moving to a Dedicated Pod model. The longest fixed price project we have shipped was 11 months. The shortest was 6 weeks.
The Change Control Charter handles it. Four tiers: clarifications are free, flex pool covers small additions, scope additions get a transparent quote, pivots trigger a re-scope. Most projects see 2-6% change orders against the original SOW, well below the industry's 60-80%. The Charter lives in the SOW, not the email thread. Change is welcomed, not weaponized.
A named pod sized to the SOW. Typically 4-10 people: a senior architect carried over from the workshop, senior engineers (FE / BE / AI), a QA engineer, a DevOps engineer, an Engineering Manager, and a Product Engineer. Resumes shared at SOW lock. Same anti-rotation clause as the Dedicated Pod page. Substitutions need your written approval with a 60-day overlap.
Payments are milestone-paced and Acceptance-Gate-triggered. Typical schedule: workshop fee upfront (credited), 25-30% at SOW lock + Foundation, 40-50% across the build milestones (paid per Acceptance Gate), 15-20% at UAT sign-off + Transition. No calendar-based billing. The milestones move payment, not the calendar. Invoices reconcile against the open-book buffer at close.
Yes. 30-day warranty period of post-launch support on any defect that violates a documented acceptance criterion. Fixes are unbilled within that window. Beyond 30 days, the natural next step is usually a small Dedicated Pod or a maintenance retainer, with no obligation. The 30-day warranty is in the SOW, not contingent on a follow-on engagement.
Encouraged. The workshop SOW is yours; if you choose to shop it, send it to other vendors and ask them to quote against the same scope. Most vendors will not produce a SOW at this level of clarity even after they win the business, which is exactly why we lead with it. If a cheaper vendor wins on price, we ask one favor: come back after the project and tell us how the buffer-pad turned out. We learn something either way.
30-minute fit call first to confirm scope, qualification, and the right entry point. If your scope is ready, we quote in 5 business days. If your scope still needs definition, the Discovery Workshop is scheduled, the squad is named, and the fee is invoiced. Either path starts with the same fit call.
NDA on request. The Team Composition Blueprint is yours to keep, with or without engagement. No follow-up sales call required.
