ENGAGEMENT MODEL

Fixed-scope project delivery

Predictable scope, predictable timeline, predictable price — for well-defined product builds where the requirements are clear and the deliverable is scoped.

WHAT'S INCLUDED

What comes with a fixed-scope engagement

Clear commercials, clear deliverables, clear finish line — with the discipline to actually reach it.

Scoped statement of work

A written SOW that specifies inputs, outputs, milestones, acceptance criteria, and out-of-scope items in plain English.

Fixed price & timeline

One quoted price and one committed timeline. Change requests are handled through a formal amendment, not a hidden variance.

Milestone-based delivery

Work is split into two-to-four milestones, each with a demo and sign-off. You always know exactly where the project is.

Clear acceptance criteria

Each milestone ships with a written acceptance checklist. Signed off means signed off — no post-hoc scope creep.

Handover documentation

Architecture notes, runbooks, and setup docs delivered with the code — so your team can operate what we built.

Post-launch warranty

A defined warranty window after launch where defects against the SOW are fixed at no additional charge.

HOW IT WORKS

From discovery to production handover

A four-phase engagement that trades speed for certainty — clear scope, clear price, real handover at the end.

01

Discovery & scoping

A short paid discovery — one to three weeks — that produces the SOW: functional requirements, architecture, milestones, and price.

02

Fixed proposal

A signed SOW with fixed price and timeline. Payment schedule and acceptance criteria are locked before we start.

03

Milestone delivery

The team delivers each milestone, demos, incorporates feedback, and gets written sign-off before moving on.

04

Launch & warranty

Production launch, handover docs, and a warranty window where SOW defects are covered at no additional charge.

WHEN TO USE THIS

Where a fixed-scope engagement is the right fit

Fixed-scope works best when the requirements are stable, the deliverable is well-defined, and finance wants a single number.

↗

MVP builds

A clearly scoped v1 — enough to validate the product hypothesis with real users, delivered against a fixed budget.

↗

Marketing site launches

CMS-driven marketing sites with a defined page count, structured content model, and a launch date pointing at a campaign.

↗

One-off integrations

A specific integration with Salesforce, HubSpot, Stripe, or a partner API — scoped, priced, and shipped without ongoing capacity.

↗

Design-system builds

A first-version component library with a defined set of components, tokens, and documentation targets.

↗

Data pipeline projects

A specific data pipeline with defined sources, destinations, and data-quality checks — delivered as a completed project.

↗

Migration & modernization

Scoped moves — off Heroku, off a legacy monolith, or from one cloud to another — with a clear cutover plan and price.

WHY THIS MODEL

What you get from fixed-scope delivery

The advantages of a scoped, priced, and warrantied engagement over an open-ended time-and-materials arrangement.

01

Fixed budget certainty

One number for finance. No hourly billing gymnastics, no surprise change orders after a bad sprint.

02

Milestone-based invoicing

Payment tied to milestones you sign off on — not to hours worked or engineers billed regardless of progress.

03

Clear acceptance criteria

A written checklist for each milestone means "done" is a fact, not a debate.

04

Post-launch warranty period

A defined warranty window where defects against the SOW are fixed at no additional charge.

✓

Real scoping, not sales-driven quotes

Senior-only engineers on delivery

The team that delivers is the team we quoted. No bait-and-switch onto juniors after the ink dries.

✓

Honest scope conversations

When requirements grow, we flag it early with a written amendment — not a silent slippage or a surprise invoice.

✓

You get real handover, not lock-in

Docs, runbooks, and clean code so your team can operate the deliverable without staying on our retainer.

FAQ

Common questions about fixed-scope projects

Practical answers on scoping, change management, and how fixed-scope engagements really work.

What happens if requirements change mid-project?
A written change amendment. We estimate the impact on scope, price, and timeline, and you decide whether to approve it. No silent slippage, no surprise invoices.
Is discovery paid?
Yes. Discovery is a short paid engagement — usually one to three weeks — because the SOW that comes out of it is a real artifact with engineering effort behind it.
What if a milestone isn't accepted?
We rework against the acceptance checklist at no additional charge until it passes. If a milestone is systemically off, we pause and adjust with you before continuing.
How long is the warranty period?
Typically 30 to 90 days after launch, depending on the deliverable. During that window, defects against the SOW are fixed at no additional charge.
Who owns the code and IP?
You do. All work-for-hire clauses assign IP to you on delivery. Code lives in your repositories from day one.
Can we roll into an ongoing engagement after launch?
Yes. Many fixed-scope clients transition into staff aug or a dedicated team for post-launch work. It's optional — never a condition of the fixed-scope engagement.
