Buying custom
business software.
Start with decisions, users and exceptions—not a feature wishlist.
Good custom software begins with process discovery. Map who does what, which information they need, what can go wrong, and how success will be measured before approving screens or estimates.
Describe outcomes and workflows
State the operational problem in measurable terms: duplicated entry, slow approvals, poor visibility, missed follow-ups or disconnected systems. For each workflow, identify roles, starting conditions, decisions, exceptions, outputs and audit needs. This produces a stronger scope than copying an old application screen by screen.
Resolve data and integration risks early
Existing spreadsheets and databases often contain duplicates, missing values and inconsistent identifiers. Decide what must migrate, who owns cleanup and how results will be validated. Confirm whether connected systems have documented APIs and whether their vendors permit integration.
Use staged delivery and acceptance
Break delivery into demonstrable milestones. Each milestone should have acceptance criteria, responsible reviewers and realistic feedback windows. Define hosting, backups, security updates, source-code ownership, documentation and post-launch support in writing.

- Evidence of discovery and process-mapping ability
- Clear assumptions, exclusions and change control
- Role and permission design
- Data migration and integration approach
- Testing, acceptance and rollout responsibilities
- Support, hosting, ownership and exit provisions
