The decision to hire a developer to finish an MVP usually arrives at the same point: the vibe-coded app is about eighty percent done, and the remaining twenty percent is something the AI keeps fixing in circles. You need a person or a team to get it to launch.

People rarely overpay here because of the rate. They overpay because of a fuzzy task, rewriting things that could have been fixed, and paying several contractors to discover the same problems. You can cut most of that before the first call.

## What to prepare before you start looking

The less a developer has to find out, the less you pay for finding out. Gather:

- **access in your own name** — repo, hosting, database, domain, payment provider, app store accounts. If anything is registered to someone else's email, move it first;
- **what works and what doesn't** — an honest list, not "it's almost done";
- **the key flows** — three to five user journeys that must work at launch;
- **current state** — are there live users, and data you can't lose;
- **what you definitely don't need now** — this list saves the most money.

It all fits on a page or two. A document you can send to three candidates makes their estimates comparable right away.

## How to scope the work

A bad task is "finish the app". A good one is an outcome you can check without a developer:

- a person signs up, pays for a subscription and gets access;
- the app is published on the App Store and Google Play;
- server errors arrive as alerts, not as complaints from users.

Split the work into stages, each with its own result. After the first stage you know how the team works and can stop without losing much. And write down what's out of scope — otherwise it shows up on the invoice as "extra work".

## A paid audit first

A free estimate of code nobody has opened is a guess. Either it has a big buffer for the unknown, or it turns out later that "it's more complicated".

It's better to start with a small, fixed-scope paid audit: the developer reads the code, checks security and infrastructure, and hands you a written result. It should cover:

- what's dangerous in the project right now;
- what can stay, what has to be redone, and why;
- an estimate broken down by the stages on your list.

The document stays with you even if you take it to another contractor. And you get to see how the person explains decisions — which makes it your trial project.

## Red flags when you hire a developer

- They propose rewriting everything from scratch without opening the code.
- They name a date and a price without asking about your users or business.
- They want to work in their own repo and accounts and hand things over "later".
- There's no written scope, only a chat thread.
- They ask for full payment upfront on a project that runs for months.
- They can't explain a decision without jargon when you ask "why".
- They vanish between invoices and show results once a month.

One flag is a reason to ask. Three is a reason to keep looking.

## Fixed price or time-based

Both models are fair when used for the right job.

**Fixed price** fits work with a clear boundary: an audit, publishing to the stores, a specific feature with a described outcome. A fixed price on a fuzzy task works against you: the contractor either adds a large risk buffer, cuts corners, or turns every clarification into a separate invoice.

**Time-based** fits when the scope isn't clear upfront: digging into someone else's code, fixing bugs, ongoing support. Its condition is visibility: a weekly report on what was done, and a cap on hours per period, after which work stops until you decide.

A common working setup combines them: a fixed audit, then fixed-length stages with a clear goal and a cap.

## Working together after you hire

- Code lives in your repo from day one, with changes in small, described pieces.
- A short weekly demo on a live environment, not screenshots.
- The contract says the code's rights transfer to you and the accounts stay yours.
- At the end, short documentation: how to deploy, where the secrets live, what's left to do.

## In short

- Prepare access in your own name, an honest list of problems and the key user flows.
- Describe outcomes you can check without a developer, and split the work into stages.
- Start with a paid audit: it's both an estimate and a trial project.
- Fixed price for clearly bounded work; time-based for unclear work, with a cap.
- Code and access stay with you from day one.

Finishing vibe-coded projects is what SUBXCAT does, and we usually start with exactly this kind of audit.
