Verify before you choose
- Confirm the exact plan and commercial terms: seats or technicians, usage limits, add-ons, taxes, contract length, renewal, and eligibility.
- Test the workflows that must work on day one, with the people who will operate them.
- Validate implementation constraints: integrations, data export, migration, onboarding scope, support, and exit requirements.
- Record unknowns rather than assuming them away; catalog inputs are curation, not vendor quotes or independent testing.
- Compare the confirmed details against your own requirements and operating context.
Use the linked vendor source for current terms. This checklist helps you test a shortlist; it is not a score, review, or universal recommendation.
