What buyers usually need
The requests that come up most often for this kind of work, and what each one takes to work properly.
01One workflow that works end to end
The single thing a user comes to do, from sign-up to result, before anything else is added.
02Logins and accounts
Sign-up, sign-in, password reset and roles, using a proven auth service rather than a home-made one.
03Payments
Stripe checkout or subscriptions, with receipts and a record of who has paid, when the app charges.
04An admin screen
A page where your team can see users, fix records and answer support questions without touching the database.
05Hosting you own
Deployed to your own hosting and database accounts, with backups and a separate test copy.
06A codebase someone else can pick up
Plain, documented code in a common stack, so a future developer is not starting from zero.
Tools that come up most: React, Next.js, Node, Python, Postgres, Supabase, Firebase, Stripe, Vercel, Render, AWS and Google Cloud.
