## This fits when
- You have a steady list of small changes and fixes, not one big project
- Quoting every job takes longer than the job
- Your app was built by someone who has moved on
- You want Stripe, Firebase, Supabase or AI work done without hiring
## How it works
1. 01 ### **Subscribe and send repo access** Pick Starter or Studio, then reply to the Stripe receipt with repo access and your first request.
2. 02 ### **Send requests in order** Add requests by email whenever you like and say which comes first. One is worked on at a time.
3. 03 ### **Review pull requests** Most requests come back in about 2 business days as a pull request with a note on what changed and how it was tested. Bigger ones are split into pieces.
## What requests and pull requests look like
Three recent changes to App369’s own website (pull requests #392 to #394), each written as the request it answered, with what came back.
