In Sage 500 a sales order is split into two invoices, one with the services, and one with the physical good and freight. The net total is different because of the tax being higher on the physical goods invoice.
- The freight tax will have changed. This must be going to a state where freight is taxable based on how much of the order is taxable. In the sales order, some of the lines were non-taxable. When the non-taxable services were all put in a different invoice, it changed the balance, making the freight get a higher taxable amount, making the net amounts not match any more. This is compliant behavior in situations where sales orders are split.
