Why does vendor master data matter in reconciliation?

Because inconsistent vendor names and GSTINs create false mismatches even when the invoice is valid.

Should vendor cleanup happen before matching?

Yes. Master data cleanup is a prerequisite for reliable invoice matching.

[003] GLOSSARY

Standardized vendor identity records used to match invoices across books and portal exports.

Vendor master data is the standardized identity record used to keep supplier names, GSTINs, and other key fields consistent across systems.

Bad master data creates false mismatches, slows review, and makes it harder to trust the output of an otherwise correct reconciliation run.

A vendor may appear under one legal name in books and a slightly different trade name in the portal export, even though the invoice itself is valid.

Teams often treat master data cleanup as a separate project instead of a prerequisite for matching.
