Engagement model
Fixed-price software development
for crypto and fintech.
A fixed price contract for software development suits teams with a settled product and a fixed budget. We scope it, price it, then build it to that number. You get working software on dated milestones, delivered agile inside each block. The scope only moves when you sign a change order for it.
- EU-based engineers
- MiCA-ready architecture
- Client-owned code
Fit
When a fixed price development contract is the right call
Fixed price software development rewards clarity. Four conditions tell us the model will hold across web, app and platform builds alike. Miss two of them and we will say so before you sign.
-
01
The scope is settled
You know the product you need. The feature list is agreed inside your team. Nothing major is still open.
- Signed scope
- Named owner
- Agreed launch date
-
02
The budget is fixed
A board or an investor approved one number. You need that number to hold from kick-off to launch.
- One price
- Phase payments
- No hourly drift
-
03
The rules are known
Your licence path is clear. We build to a MiCA or VASP scope and leave the legal calls to your advisers.
- MiCA-ready design
- GDPR-aware data
- Audit evidence
-
04
You want one owner
One EU team runs discovery, build, hardening and launch. You brief once. You chase nobody.
- Single contract
- Named engineers
- 24/7 cover after launch
Delivery
Fixed price contract agile software development, phase by phase
Each phase has an output you can inspect and a payment tied to it. Inside each phase the team ships in sprints. Nothing is billed against a promise.
Building a venue? The technical detail sits on our crypto exchange development page, alongside wallet and custody engineering, on- and off-ramp integration and the wider fintech infrastructure layer.
- 01
Scoping sprint
2–4 weeks · Paid separately
Architecture view, risk list, test plan and the priced scope we then sign.
- 02
Build blocks
Fixed milestones · On milestone sign-off
Working software each block. You review it in a real environment, not a slide.
- 03
Hardening
Runs in parallel · Inside the price
Security review, load tests, AML and Travel Rule paths, plus the audit trail.
- 04
Launch & handover
1–2 weeks · Final milestone
Cut-over, runbooks, source handover and a support plan with named engineers.
Scope
What a fixed price development contract covers
A fixed price is only useful if the boundary is clear. Here is what sits inside every fixed price web development, app or platform build we sign.
-
A signed scope
Every screen, service and interface is listed before we start. What is out is listed too.
-
A dated plan
Milestones carry dates. You see slippage in the same week it happens, not at the end.
-
Client-owned code
You own the source, the infrastructure and the docs. No white-label lock-in, no seat fees.
-
Tests and evidence
Automated tests ship with the build. Logs and reports go to your reviewer on request.
-
One change process
New ideas get priced as a change order. The base price stays honest.
-
A warranty window
Defects against the signed scope are fixed free for thirty days after launch.
Alternatives
If a fixed price does not fit
Pick the model that matches how settled your plan is. Many buyers start with advisory or augmentation, then move to a fixed price development contract once the boundary is clear.
-
Dedicated team
A standing squad with a lead. Best for long roadmaps that keep moving.
-
Staff augmentation
Senior engineers inside your team. Best when you own the plan already.
-
CTO advisory
Architecture and hiring guidance. Best before you commit to a build.
Questions
FAQ: fixed price software development
Six answers on how the contract holds, how agile fits inside it, and where web and app scopes differ. Bring the rest to the call.
How does a fixed price development contract actually work here?
The scoping sprint produces a document set — architecture, interfaces, risk list, test plan — that is detailed enough to price. We then quote one number and one dated plan against that document. You sign a fixed price development contract, milestones are paid on inspection, and any new idea enters as a priced change order rather than quiet scope creep.
Do fixed price contract software development and agile fit together?
Yes. Fixed price contract agile software development works when the boundary is fixed and the interior stays agile: milestones are outcome-based, not screen-by-screen, and inside each milestone the team plans, ships and demos in sprints. You sit in reviews, you shift priorities inside the milestone, and you never wait until the end to see working software.
Do you cover fixed price app development and fixed price web development?
Yes. Fixed price app development, fixed price web development and API or back-office builds all use the same model. Mobile scopes usually add a hardening phase for store review and device coverage; web scopes typically fold in accessibility and Core Web Vitals work. Both sit inside the priced plan, not outside it.
Is a fixed price safe for regulated crypto and fintech work?
Yes, when compliance sits inside the scope. We design to MiCA, PSD2 and AML / Travel Rule expectations from day one and produce the evidence — logs, reports, runbooks — as we go. Licence opinions still belong with your lawyers; we do not offer legal advice.
What happens when we want a new feature mid-build?
We price it as a change order with its own date and payment. You approve it, park it, or drop it. The base contract price stays honest because scope only moves when you sign for it.
What if our scope is still moving?
Then a fixed price is the wrong tool. Start with staff augmentation or a dedicated team while the plan settles, and switch to a fixed price development contract once the boundary is clear. Forcing a fixed price around a moving scope produces the exact overrun the model was meant to avoid.
