What makes automated intercompany matching work?

Detailed Explanation

Standardised reference fields, above all. Automated rules can only match on what both sides recorded, so a shared transaction identifier written consistently at source does more for the match rate than any tuning downstream. After that, rules layered by confidence: exact matches cleared automatically, tolerance-based matches cleared with a logged rule, and everything else routed to a human. The measure that matters is time-to-resolution, not the raw match percentage. A high auto-match rate that leaves the hard breaks untouched until day eight of close has not solved the problem.
