Custom software

The exact tool your business needs.

Shared spreadsheets, re-keying, tools that do not talk to each other: when your process is your advantage, it deserves its own software. We build secure, scalable business web applications whose code belongs to you.

Frequently asked questions

Who owns the code?

You do. The code, documentation and access are handed over under the terms set out in the contract.

How long before a first version?

Scoping sets a first usable scope; its timeline is estimated and committed to in the proposal, not before.
