Zero-Hallucination AI Quoting: Why Pricing Belongs in PostgreSQL, Never Prompts
Direct Answer Summary
Zero-hallucination quoting restricts language models to structured scope extraction while delegating all arithmetic, tier lookups, bundle modifiers, and margin-floor enforcement to deterministic server functions and PostgreSQL.
The Architecture of Safe Autonomous Pricing
Finance leaders rightly reject any AI workflow capable of inventing unauthorized discounts or miscalculating multi-year contract totals. Probabilistic token prediction should never perform commercial arithmetic.
In the LeverageIQ reference pattern, conversational interfaces collect typed JSON inputs (seat counts, facility locations, SLA tier, mobilization timeline) validated by strict server schemas. A deterministic pricing engine computes the exact line items, logs the quote snapshot in PostgreSQL, and returns an immutable quote ID.
Human-in-the-Loop Escalation Gates
Standardized tiers ship instantly so buyers maintain momentum at 10:00 PM on a Sunday. Whenever a scope crosses a custom enterprise threshold or requests non-standard legal terms, the engine automatically flags executive review while locking a scoping call on the principal calendar.
Key Questions Answered
Can the same deterministic pricing engine power both our website and AI agent API?
Yes. Both interactive human web calculators and machine-to-machine /api/acp/negotiate calls invoke the exact same server-side pricing module.
Is every generated quote auditable?
Every quote records input parameters, rule version, line-item math, and timestamp in PostgreSQL for complete financial auditability.
