Compare the operating model, not the marketing adjectives.
This comparison is intentionally conservative. Competitor entries mean “documented in public/vendor material reviewed”, not independently tested. “Not evidenced” does not mean a competitor lacks the feature.
Evidence review: full competitor research reviewed 24 September 2026; official vendor pages spot-checked 16 October 2026 with no material contradiction identified. Re-review by 24 December 2026, and earlier if a compared vendor materially changes its product or public documentation.

Where RetailHawk is choosing to be different
Explicit state boundaries
Assignment, completion evidence, review, client release and payment are modelled as separate concerns rather than compressed into one status.
Tenant-denial testing
Cross-tenant negative tests are treated as engineering acceptance, not assumed because a user interface hides a record.
Provider hand-off integrity
The external-survey framework uses authenticated completion evidence and preserves provider/version context for configured providers.
