Custom web app takeovers: finish bespoke software for your business

A custom web app is software written for one organisation's way of working: a booking system for a clinic, a quoting tool for a manufacturer, a members' portal, a niche marketplace. Stacks range widely, from Django and Laravel to Ruby on Rails, ASP.NET and Node.js with React. What these projects share is a single original builder and business rules that exist nowhere except in the code.

What developers usually find

Bespoke builds are often deployed by hand, with files uploaded over SFTP or a script run on the server, and no separate staging environment. Business logic tends to be scattered across controllers, database triggers and front-end code. Configuration values may be hard-coded, and admin features the owner relies on daily are sometimes unfinished or hidden behind a URL nobody documented.

Making the handover easier

Write down each business process the app must handle, in your own words, including exceptions such as cancellations or refunds. Gather access to the repository, server, database and domain under accounts you control; the handover checklist generator produces a list tailored to your setup. Mention who uses the app today and what would happen if it went offline for an afternoon, because that shapes how carefully a developer must work.
