You do not need to become a software engineer to evaluate a vendor. You need a clear business workflow, comparable evidence, transparent ownership and an independent way to test whether the proposal can deliver the outcome.
Give every vendor the same problem
Describe users, current work, exceptions, data, integrations and acceptance outcomes. Comparing proposals against different assumptions makes price and timeline comparisons meaningless.
Ask for evidence, not confidence
Request relevant working examples, explanation of tradeoffs, a delivery cadence and the people who will actually perform the work. A polished sales call is not delivery proof.
Make ownership visible
Clarify source code, infrastructure, accounts, data export, third-party licenses, documentation, credentials and transition support before work begins. Avoid unnecessary dependence on vendor-controlled access.
Examine what the estimate excludes
Administration, permissions, migration, testing, content, integrations, support and exception handling often sit outside the visible screens. Ask how uncertainty will be investigated and approved.
Define acceptance and governance
Agree on working demonstrations, decision owners, change control, risk reporting and what constitutes acceptance. Independent technical guidance can protect the business without displacing a capable vendor.
A practical checklist
- Name the outcome in plain language.
- Map the current people, responsibilities and exceptions.
- Separate evidence from assumptions.
- Make ownership, cost and operating risk visible.
- Choose the smallest next step that reduces a material unknown.
What to bring to a first discussion
Bring the decision, evidence and desired outcome. A focused consulting conversation can stand alone; no software purchase is required.
