# Custom Build: full-stack development scoped from your Starter

You know what to build. Now you need it built right.

You’ve got a verdict, a prototype, or an honest read on what you have. We build the rest as a partner, in your repo, from the scope we already wrote down together.

What you walk away with

Working software in production, and it’s yours.

Every build begins with a Starter. The Starter gives us both the facts before we set a price.

## Is this you?

Check any that fit. If two are true, you’re in the right place, and your answers come with you to the form below.

* You finished a Starter, and the answer was yes.
* You know what needs to be built, and you don’t want to start discovery over.
* You want to own the code outright, not rent it.
* Your board needs a fixed number before it approves the budget.
* You’ve been handed a half-built app before, and you won’t do that again.

## What’s true now

You know what needs to exist. You’ve read the verdict, held the prototype, or seen the audit. What you don’t have is a team you trust to finish it.

## What’s true after

It’s live, it’s yours, and you didn’t have to manage it into existence.

## Your timeline, start to finish

1. 01We turn your Starter into a fixed statement of work: scope, cost, and sequence.
2. 02Design and a clickable prototype come first, before heavy code.
3. 03We build in your repo, and you see working software every two weeks.
4. 04We test, launch to production, and stay with you for 30 days after.

What you walk away with

## Working software in production, and it’s yours.

* Your repo and your code from the first commit, whoever maintains it later.
* A fixed price you agreed to before we started.
* 30 days of support after launch, then the choice of an Embedded Team or handing it off.

## What’s included

* Design you can click through before we write production code.
* Web or mobile, built by senior engineers, reviewed before it reaches you.
* Testing and a production launch, handled.
* 30 days of support after launch.
* Fixed-price statement of work, or monthly as an Embedded Team: your call.

## Where this starts

Most builds arrive from one of these:

* [Idea Check →A verdict on an idea.](https://heartwood.agency/services/idea-check)
* [Prototype →A working prototype you own.](https://heartwood.agency/services/prototype)
* [Code Audit →An honest read on code you don’t trust.](https://heartwood.agency/services/code-audit)

## Questions you’re probably asking

How much does custom software cost?+

Builds start at $20,000\. Yours is priced from the scope your Starter produced, so you know the number before you commit.

Can we skip the Starter?+

No. We can’t quote a build responsibly without due diligence, and the Starter is that due diligence. If you already have a spec from someone else, an Idea Check or Code Audit reads it first.

Who owns the code?+

You do, from the first commit.

What happens after launch?+

Every Custom Build includes 30 days of support after launch. After that, when you’re ready, an Embedded Team keeps it growing: $6,500/month per quarter lane, 3-month minimum. The code is yours either way.

Fixed price or monthly?+

A Custom Build is a fixed statement of work: a defined build, a defined price, agreed before we start. If the scope will keep growing rather than finishing, that is an Embedded Team instead, billed monthly by the lane. We will tell you which one your work actually is.
