What happens at each step of a custom build?

Every custom project follows the same five steps, from your first message to a live platform.

1. Form

You send the project details: what you want to build, who will use it, and your budget range.

2. Consultation

A call to discuss what you need, which parts can come from existing code and which must be built new, and which systems it must connect to.

3. Proposal

You receive a written proposal with timelines and costs. Nothing is built before you agree.

4. Development

The team builds the platform or feature and connects it to your systems, for example analytics, payments, fraud detection and traffic sources.

5. Delivery

Handover of the finished software, with ongoing support: post-launch support, maintenance and updates.

How long it takes

Simple additions take weeks; full platforms take months. You get an estimate after the project is evaluated.

Who owns the result

You do, with full ownership and control. Unless you agree otherwise, it is not resold to other clients.
