# How we quote custom software at a fixed price, with no surprises

> The short answer: Most software quotes are ranges that balloon later. Here is exactly how fixed scope and price works, turning an idea into a firm number up front.

The worst part of buying software is not the price — it is the uncertainty. A vague range up front, then change orders and surprise invoices as the project drifts. It does not have to work that way. Fixed scope and price means the number is agreed in writing before we build, and it holds. Here is exactly how we turn an idea into a firm quote, with no surprises after.

## Why do most software quotes balloon?

Open-ended quotes balloon because the scope was never pinned down. "Build me an app" hides a hundred decisions, and each one made mid-project is a chance to add cost. Billing by the hour makes this worse, because the meter runs whether or not the plan was ever clear. The problem is rarely a dishonest vendor — it is starting to build before anyone agreed what "done" means.

## How does fixed scope actually work?

- We define exactly what gets built — the screens, features, and integrations — in writing.
- We agree the number for that scope before a single line of code is written.
- That number holds for that scope. There are no surprise invoices.
- If you want to add something later, it is a new, separately quoted piece — your choice, not a drift.

The discipline sits entirely up front: spend the time to make the scope concrete, and the price becomes a fact instead of a guess. You know the number, and exactly what you get for it, before you commit to anything. A short written update from us every week keeps that agreement honest as the build progresses — what shipped, what is next, and what we need from you — so the fixed number never quietly drifts away from what is actually being built.

## What about the things you cannot foresee?

Real projects surface new ideas partway through — that is healthy, not a failure of planning. The difference is how they are handled. Instead of a change order that quietly grows the bill, a new want is scoped and priced as its own small piece you decide on, with the original scope still delivered at the original number. You stay in control of what you spend, always by choice, never by drift.

## Why is this better for you?

Fixed scope aligns us with you. We are motivated to scope carefully and build efficiently, not to let the clock run. Roughly half of a US agency's cost, fixed in writing before we start. That is the number you are working from, not a range that grows as the weeks pass. You can budget with confidence, and you own everything we build. NDA first. Full handover of code and documents. No lock-in. 30-day warranty. If a defect turns up after handover, it gets fixed inside that warranty, at no extra line on the invoice you already agreed to.

## What would we build first?

Before we quote anything, we spend the first conversation getting specific about the one workflow that matters most — what it needs to do, who uses it, and what can wait for a later stage. That becomes the scope the price is fixed against, and the first release arrives inside three-day sprints, with a working version in your hands every two weeks from there. You can see that cadence laid out day by day on [how we deliver](https://buildwithik.com/how-we-deliver). If you are still comparing this against building nothing custom at all, our note on [custom versus off-the-shelf software](https://buildwithik.com/blog/custom-vs-off-the-shelf-software) is a useful companion, and our breakdown of [what app development actually costs](https://buildwithik.com/blog/what-app-development-costs) covers the same ground from the pricing side specifically.

## Where to start

Bring the outcome you want and the one workflow that matters most. On a [20-minute call](https://buildwithik.com/book) we turn that into a concrete scope and a firm number, so you can decide with a real price in front of you, not a range and a hope.

## Questions people ask

### How does fixed-price software development work?

We define exactly what will be built — screens, features, and integrations — in writing, then agree the price for that scope before any code is written. That number holds for that scope, with no surprise invoices. Anything you add later is a new, separately quoted piece you choose, rather than a drift that quietly grows the bill.

### Why do most software quotes end up costing more than expected?

Because the scope was never pinned down. "Build me an app" hides many decisions, and each one made mid-project can add cost, especially under billing where the meter runs regardless of clarity. The fix is defining what "done" means in writing before building starts.

### What happens when new requirements come up mid-project?

They are scoped and priced as their own small piece you decide on, while the original scope is still delivered at the original number. That keeps you in control of spending by choice, instead of absorbing surprise change orders.
