Software Discovery Checklist for Comparable Proposals
Prepare users, workflows, integrations, acceptance criteria and scope boundaries so software suppliers can quote the same project.
Before requesting development proposals, document the business outcome, users, essential workflows, systems to connect and evidence needed for acceptance. Suppliers cannot give comparable estimates if each one is imagining a different product.
A useful proposal starts with the same brief
You do not need a complete technical specification to begin. You do need to distinguish requirements from assumptions and first-release needs from future ideas. If you have not written anything down yet, start with a one-page project brief; this checklist is the next level of detail, aimed at getting proposals you can compare.
Prepare these eight inputs
| Input | What to write |
|---|---|
| Business problem | The task causing delay, errors, lost opportunities or unnecessary effort |
| First-release outcome | What someone must be able to complete after launch |
| Users and permissions | Roles, approval authority and the information each role may access |
| Core workflows | Normal path, exceptions and the responsible person at each step |
| Existing systems | Current tools, owners, available documentation and sample data |
| Data migration | Records, quality issues, history required and reconciliation method |
| Acceptance | A demonstration or test that proves each requirement is met |
| Constraints | Budget boundary, required dates, decision makers and dependencies |
For an integration, “connect the accounting system” is incomplete. Explain which records move, in which direction, how often and who handles rejected records. Mark API access as unconfirmed until the system owner verifies it.
Separate design from development
If you will supply UI/UX designs, say whether they include mobile layouts, empty states, permissions, validation and error screens. Agree how incomplete screens will be resolved. A supplier’s estimate can change materially when it must design missing interactions during implementation.
If you do not have designs, request discovery or design as a separate line item. You can then evaluate that work before committing to the build.
Turn uncertainty into a decision
Use a simple table: open question, owner, due date and effect on scope. A low-impact uncertainty may be covered by a clearly stated assumption. An unknown that changes the architecture or integration effort may need investigation before a fixed build quote is sensible.
Ask suppliers to show exclusions, dependencies, recurring services, handover and change control — the sections a sound development proposal should contain. A smaller first release with explicit boundaries is easier to compare than a long list of unpriced features. When the answers arrive, compare the quotations on the same scope before comparing totals.
Bring the right people
Include the sponsor, a person who performs the work and whoever owns affected systems. Their job is to resolve contradictory requirements and identify exceptions early. No checklist substitutes for seeing how the process actually works.
