What to include
- The goal: what problem the system solves and how you will measure success.
- Users and roles: who uses it and what each role can do.
- Main scenarios, step by step, from the user's point of view.
- Integrations: payments, 1C, SMS, government systems, with links to their documentation.
- Non-functional needs: number of users, languages, where data must be stored, security.
What keeps the budget stable
- A list of what is explicitly out of scope for this stage.
- Stages with a clear result each, and acceptance criteria for every stage.
- A simple change process: new requests are estimated and approved before work starts.
You do not have to write it alone
- A good contractor helps turn your notes into a specification. At Eurosoft, after a short call we prepare a proposal with stages, days and prices, and the specification becomes an appendix to the contract.
Questions and answers
- Do I need a full specification before contacting a developer?
- No. A clear description of the goal, users and main scenarios is enough to start; the specification is refined together with the contractor.
- How do I avoid the budget changing during the project?
- Fix the scope per stage, list what is out of scope, and agree that every new request is estimated and approved before it is built.
