Voice AI Agency Contracts: Trace Each Promise to Verifiable Proof

A DEV Community article advises buyers evaluating voice AI agencies to judge proposals by the evidence behind each promise rather than by feature lists, demos, or first-year pricing. It recommends a ledger linking each material promise to the caller scenario, responsible operator, authoritative system, expected evidence, acceptance rule, recurring cost, and exit path. The author distinguishes a services proposal, which defines who will deliver and test the work, from a platform comparison, which only assesses software capability. Integration claims such as CRM connections should be spelled out as specific operations and the records that prove them. The piece also draws on UK government AI procurement guidance and CISA's secure-by-design resources as voluntary checklists, not binding rules for private buyers.
