You can batch select the invoices and the format of both would have everything you need including all of the line items that have been keyed in and the coding – department, nominal, cost & project.
The second way is to run our sync program that downloads all of the invoice line items and headers on a schedule when they are a particular status – say approved. You would then have two database tables – say SQL. This would be a program you install on your own network on a Windows server or PC. The database could be either MS SQL or Access.
So with option 1, you would either need a folder monitor program to read those files and import or would have to use any built in import functionality in your account system – ie File > Import.
With option 2, you would be looking for a script or program to harvest the information from the staging database and read it into your accounts system
