01The work

Every app stands on a backend: the API it calls, the database behind it and the tools your staff use to run it. We build that layer so it is fast, holds up as you grow and keeps each user to the data they are allowed to see.

Because we also test systems for a living, security is part of the build rather than a review at the end. You get documentation and integrations your next developer can pick up without calling us.

Who it is for
  • Teams with an app that needs a real API behind it
  • Businesses moving from spreadsheets to a proper system
  • Products that need to connect to payment or messaging services

04Questions

Can you build the API for an app we already have?

Yes. We can build a new API for an existing app, or take over and secure one that is already running.

Do we get documentation?

Yes. The API and how to run it are documented as part of the work.

Can our staff manage the data themselves?

Yes. An admin dashboard lets your team manage users, content and records without a developer.

How is the price set?

The price on this page is where the work starts. After a short call we send a written quote with the scope, price, dates and what you will receive. It holds for 30 days.

How do we pay?

In US dollars unless the quote says otherwise: a deposit before work starts and the balance on delivery. Invoices are due within 14 days.

Who owns the work?

You do, once it is paid in full: the code, designs and content we made for you. Tools we had before stay ours, and you get a permanent licence to use them in the work.

What if something does not match the quote?

Tell us within 14 days of delivery and we fix it at no charge.
