Can I find out what the csv file needs to look like to be imported into payables for employee expense eft payments? Or does it just need to match the import field selection screen in a template for invoice imports?

All imports into Adagio are driven from Templates so you can choose the order of the fields coming in. Pressing F1-Help under File | Import | Manual Checks will give you all the fields you can choose from, and what information is required. The Import Template allows you to specify defaults for any fields not included in the incoming data.

There are also examples of all the various imports included in the sample data.
