# Trial Invoice Zero Versus Paid Review

Keep a zero trial invoice distinct from evidence of a paid subscriber.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Subscription and invoice IDs, trial dates, invoice totals/status, payment evidence and supplied conversion policy.

## Workflow
1. Match trial invoice and subscription by stable IDs.
2. Separate zero-value trial billing documents from positive paid invoices and cash.
3. Apply supplied conversion criteria without substituting invoice status alone.
4. Return unproven conversions and evidence gaps; no billing action.

## Output contract
subscription | trial_invoice | invoice_total | paid_cash_evidence | conversion_policy | conversion_unverified

## Fictional acceptance test
Fictional trial invoice 0 has statuspaid but no positive payment. It does not prove a paid conversion. A later 20 paid invoice needs its own payment and policy evidence.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
