## TL;DR

Vendor names on invoices rarely match the master exactly: abbreviations, legal suffixes, and DBA names all vary. Normalize (lowercase, strip Inc/LLC/GmbH, remove punctuation), then fuzzy-match with a scored threshold, and confirm high-value matches against tax ID or remit-to details. Keep a vendor alias table so each learned variant matches instantly next time.

## Steps

1. Normalize the invoice vendor name: case, punctuation, legal suffixes.
   Expected: A canonical string.
2. Score against master names with fuzzy matching.
   Expected: Ranked candidates with scores.
3. Auto-accept above a high threshold; review in the middle band.
   Expected: Fast path plus human judgment.
4. Confirm with tax ID or bank details for large amounts.
   Expected: A second factor for money.
5. Store accepted aliases in the vendor alias table.
   Expected: Learning that compounds.

## When to use

- Vendor name variants on invoices
- New invoice layouts from known vendors
- Vendor master cleanup projects

## When not to use

- New vendors (onboarding flow)
- Tax ID validation
- Bank detail changes (fraud flow)

## Compatibility

Extractor-agnostic; needs vendor master access. Libraries: rapidfuzz, dedupe.

## Variant phrasings

### fuzzy match vendor name

### ACME vs Acme Corp vendor

### vendor alias matching

## Root cause

Vendors write their own names inconsistently, and master records were entered by hand over years. Exact matching fails on real-world data; scored matching with aliases is the practical answer.

## Edge cases

- Acquisitions create legitimate name changes; update the master, not just aliases
- Different vendors with similar names need tax-ID disambiguation
- Non-Latin scripts need transliteration before matching
