Every quote here is fixed before work starts. If the scope changes, we agree a new number first — you will never open an invoice you did not expect.

What moves the number

Most apps fit in $2,500. A few do not, and it is usually one of these. The audit week exists so we find out before you have spent anything on the build.

Real-time anything
Live chat, multiplayer, location tracking between users. The software is not hard; keeping it correct under load is.
Payments beyond a checkout
Subscriptions, marketplaces, payouts to other people. Each one drags compliance behind it.
Integrations with something old
If it has to talk to software written before 2010, the unknown is their side, not mine.
A design you already have
Usually cheaper, occasionally not. A polished Figma file speeds things up; a mood board does not.

Still cheaper than finding out later

Start with the audit. A week and $500 tells you what your app costs to build, and the $500 comes off the build if you go ahead.
