Hourly billing made sense when software estimation was a black box. It is not one anymore. As a fixed price mobile app development company, we scope the project with you, put one number in writing, and build to that number. If the scope does not change, neither does the price.
A 30-minute scoping conversation with the founders.
Why the price does not move
Hourly rates made sense when scoping software was genuinely hard to do upfront. That is no longer true for the vast majority of mobile and web products. The tools, patterns, and experience to scope a project accurately exist today. What hourly billing mostly protects now is the agency, not the client: every unclear requirement, every slow week, every "can we also add" shows up on your invoice, and you only find out the real cost once it is too late to do anything about it. A fixed price reverses that. We take on the risk of a fuzzy spec, which only works if we scope the project properly before anything is signed.
A real scoping call, turned into a written spec. You see exactly what you are paying for before any number is discussed.
A single quote covering the whole spec, plus a timeline. Nothing hidden, nothing added later without your signoff.
If the build runs longer than planned on our side, that is our cost to absorb, not yours. That is the actual point of fixed price.
No incentive on our side to stretch hours. Our incentive is to ship the agreed scope well, since that is what gets paid.
What the fixed price covers
The price covers a defined scope, built to a defined standard. Anything outside that scope gets its own quote, agreed before we touch it, never folded quietly into the number.
Screens, features, backend needs, and integrations, documented before you sign anything.
Flutter or React Native, whichever fits your project, built to the agreed document.
NestJS or Supabase backends, authentication, and business logic included in the scope.
Live demos every two weeks so you see working software, not a status email.
End-to-end testing across real devices before anything ships to the store.
Full App Store and Google Play submission, certificates and provisioning included.
Prefer to plug engineers into your own team instead of a full fixed-price build? We also do that, see how on our outsourcing page.
Not included: features requested after signoff, third party costs like app store fees or paid APIs, and ongoing maintenance after launch. All of that is quoted separately, never folded into the build price.
Why the number holds
Plenty of agencies say fixed price and quietly bill for scope changes anyway. Here is what makes ours hold.
Thomas and Kamil run the scoping call directly. The people accountable for the number are the ones who set it.
The quote is a document, not a verbal estimate. What you sign is what you pay.
If your idea is too large for your budget, we say so before you pay, not after.
Two-week sprints with live demos, so you see the build, not just an invoice.
Contracts in English, invoices in USD, and real overlap with US working hours.
Code, credentials, infrastructure. Clean handoff at the end, whichever way the project goes, whether you continue with us or hire developers directly to maintain it.
From the founder
"Business needs predictable outcomes. You want to know exactly what you are paying for, and what the KPI on the other end of that spend is. That is why we work fixed price."

A clear process with no ambiguity. You always know what is happening and why.
Walk us through your product and constraints. We ask the right questions and tell you what is realistic. No pricing yet.
The conversation becomes a document: screens, features, backend needs, integrations. You see exactly what you would be paying for.
One number covering the whole spec, plus a timeline. Nothing hidden, nothing added later without your signoff.
We build against the agreed document with live demos every two weeks, full QA, and store submission at the end.
