02 / Product
Custom Apps
Shopify apps, internal tools, React Native. No vibe coding.
There is a lot of software being generated right now that works in the demo and falls over in month three. We build the other kind. Tested, documented, deployed properly, and still maintainable by someone who is not us.
01 / Who this is for
Four situations we see most.
Brands who have hit the ceiling of what apps from the Shopify store can do
Teams running critical operations in a spreadsheet that three people understand
Companies with a mobile product that needs a rebuild rather than another patch
Anyone quoted an enterprise price for something that should be a small tool
02 / What is included
Everything in the build.
Custom Shopify apps: private, custom and public, with proper OAuth and scope handling
Internal tools: ops dashboards, inventory and fulfilment tooling, admin interfaces
React Native apps for iOS and Android from one codebase
API and integration work: Storefront API, Admin API, webhooks, headless patterns
Data migrations off legacy platforms
Testing, CI and deployment set up from day one, not retrofitted
03 / How it works
Five phases. Scoped to you.
01 Definition
1 to 2 weeks
What it does, what it does not do, what it costs. Written down before anyone builds.
02 Prototype
1 to 2 weeks
A working thing you can use, not a clickable mockup.
03 Build
4 to 12 weeks
Two-week increments, deployed to staging each time.
04 Ship
1 week
Production deploy, monitoring, docs, handover.
05 Support
Ongoing
We stay on it, or hand it to your team with documentation they can actually follow.
Price band
Small tools from $8k. Full applications from $30k.
State a number. "Custom proposal" costs you the enquiries from people who were qualified and just wanted to know if they were in range.
