This document describes how to define and manage sales tax in M3 BE when third-party system Vertex is used to calculate sales tax on customer invoices. With this solution, reporting and reconciliation of sales tax is performed in Vertex.
Vertex is used to calculate sales tax when customer invoicing is performed in M3. The required information from M3 is transferred to the Vertex application, where the sales tax is calculated and returned to M3. The total tax amount is accounted in M3 and if the 'Update tax details' check box has been selected in 'Settings – Sales Tax' (CRS793), detailed tax information can also be reviewed in 'CO Invoice. Display Transactions' (OIS354) or 'MCO Invoice. Display Transactions' (COS354). All reporting and reconciliation of sales tax is performed in Vertex.
