# Receipt expense extraction

## Purpose

Turn receipt evidence into structured accounting rows without losing uncertainty. Each extracted field remains linked to the receipt and is checked against the related claim and policy.

## Scope

Read receipt fields, normalize dates and currencies using supplied references, match receipts to claims, classify expense categories, and flag policy or reconciliation issues.

**Excluded:** payment execution, reimbursement approval, tax filing, foreign-exchange invention, and correcting source records.

## Data basis

- Receipt images or PDFs with receipt identifiers.
- Expense claim table with claimant, claimed amount, currency, cost center, and submission date.
- Merchant, currency, tax, category, and cost-center reference tables.
- Expense policy and existing ledger for duplicate and reimbursement checks.

## Result

A receipt ledger with confidence and citations plus an exceptions memo.

## Quality criteria

- Every receipt has a stable receipt ID, source citation, extraction status, and field-level confidence.
- Receipt total equals subtotal plus tax and adjustments when those fields are present.
- Claim and receipt amounts reconcile within the policy tolerance.
- Currency conversion names its supplied rate and effective date.
- Unreadable or conflicting fields are blank or unresolved, never guessed.

## Instructions

Preserve the printed value and currency before any normalized amount. Use the company’s supplied exchange-rate table only. Match on claimant, merchant, date, amount, and receipt ID; do not force a weak match. Treat duplicate receipt IDs and near-identical merchant-date-amount combinations as review cases. Apply policy category and missing-receipt rules exactly.

## Adapt before use

Record the extraction timestamp and source page for multi-page receipts.
Keep amounts exactly as printed before normalization.
Original receipt images remain the evidence of record for every extracted field.

- Map receipt, claim, ledger, and master-data fields.
- Provide currency rates and effective-date rules.
- Set reconciliation tolerance and duplicate logic.
- Add expense categories and missing-receipt policy.
