3-Way matching functionality comes in handy to determine the validity of the vendor
bill and to determine whether it should be paid. The feature allows you to compare
the data appearing on the purchase order, receipt, and vendor's bill. It also prevents
the customer from paying fake vendor bills. Firstly we have to enable it from the
settings of the Purchase Module. Go to Purchase - Configuration - Settings - Invoicing
- 3-way matching: purchases, receptions, and bills Then click the “Save” button.
