Vendor master cleanup
Stop paying the same vendor twice.
Vendor master files grow by accretion — new POs add vendors without checking for duplicates. Typo variations ('Acme Corp' vs 'Acme Corp.') and tax-ID formatting differences ('12-3456789' vs '123456789') create invisible duplicates. The Genie finds them with TIN-validated matching + address + name fuzzy scoring.

The problem
Vendor master duplicates cause real money problems.
Same vendor paid twice because Accounts Payable couldn't find the existing record at PO time — entered as new.
1099 tax reporting splits vendor payments across 2-3 records. IRS reconciliation gets ugly.
Tax ID (EIN / SSN) formatting variations ('12-3456789' vs '123456789') mean duplicate-prevention checks fail.
Vendor name variations: 'Acme Corporation', 'Acme Corp.', 'Acme, Inc.', 'ACME CORP'. Each version creates a separate vendor record.
Address normalization issues ('123 Main St.' vs '123 Main Street Suite 400') fragment the same vendor across physical locations.
Banking info (ACH routing + account) gets attached to only one duplicate — payments bounce on the others.
How the Genie solves it
Vendor-specific matching with TIN validation
EIN / SSN normalization
Tax IDs are stripped of hyphens + spaces before matching. '12-3456789' and '123456789' are the same TIN. Engine also Luhn-validates SSN formats and flags invalid ones for investigation.
Legal-suffix awareness
Folds 'Inc', 'Inc.', 'Incorporated', 'Corporation', 'Corp', 'LLC', 'Ltd', 'Ltd.', 'Company', 'Co.' to a single canonical form before matching. 'Acme Corporation' and 'Acme Corp' are the same vendor.
Address-level fuzzy matching
Street abbreviations (St. / Street / STREET), suite/apt variations, ZIP+4 padding all normalized. Same vendor at the same address matches cleanly even with formatting variance.
Banking-info reconciliation
Match the vendor master against a banking file to find which vendors have valid ACH details attached — and which are paid by check because their banking info lives on a duplicate record.
1099 reporting ready
Run the match against your 1099-eligible vendor list to find duplicates that split payment totals. Output tells you which IDs to consolidate before year-end filing.
Runs on your ERP exports
Oracle, SAP, NetSuite, QuickBooks, Sage, Microsoft Dynamics all export vendor masters to CSV. No ERP integration required — export, match, export corrections.

Same pattern for quarterly AP cleanup, year-end 1099 prep, or vendor consolidation post-M&A.

reviewTIN matches exactly — strong signal. But name difference is semantic ('Supply Co' vs 'Supplies, Inc') — could be same vendor under two legal names, or a data-entry error. Review to decide before consolidating.
Before and after
What changes when you use ListMatchGenie
Without ListMatchGenie
- Duplicate vendor payments in the 0.5-3% range of AP volume — for a $100M AP org, that's $500K-$3M a year.
- 1099 reporting splits payments across duplicate IDs, creating IRS reconciliation headaches.
- Vendor maintenance takes longer because AP clerks search for existing records and don't find them (due to formatting variance), then create new ones.
- Banking info lives on one duplicate, paper checks get issued on the other. Vendor calls wondering why payment came via check instead of ACH.
- Post-M&A vendor consolidation is a 3-6 month project of manual spreadsheet work.
With ListMatchGenie
- Quarterly cleanup runs the match in 5-10 minutes, produces a list of duplicate groups, AP reviews + merges in 1-2 days.
- 1099 prep includes a dedup pass so totals roll up cleanly.
- Vendor-search workflows (in your ERP, outside the engine) benefit from cleaner masters.
- Banking info can be consolidated onto the surviving record; ACH rollout completes faster.
- M&A vendor consolidation timeline cut to 2-4 weeks.
