Invoice Matching Beyond 3-Way Match for Manufacturers in 2026
Standard 3-way matching misses service invoice drift. What manufacturers need: contract-to-invoice matching, Virtual GRN, and continuous enforcement.
Invoice matching has not evolved in 30 years. The same three-way match from the 1990s remains the primary AP control. For goods — where physical items arrive at a dock and can be counted against a PO — it works. For services, it never did. And services now represent 30 to 60 percent of operating costs.
