This topic describes how to write an interface to an accounting system. The accounts system interface is written as a Lua script so you need to be be familiar with Lua and how it is integrated into Match-IT (see the Lua topic). The description here is only concerned with the interaction between your script and Match-IT, it does not cover the specifics of any particular accounting system. Refer to your accounting system documentation for that.
The accounts system interface is responsible for the management of the information transfer from Match-IT to the accounts system and vice versa. Information that can be sent to your accounts system is new customer and supplier accounts, new stock codes, sales invoices, purchase invoices and stock movements. Information that can be extracted from your accounts system is customer and supplier address changes and their current credit position.
