Importing invoice payments:

Enter the payments into your accounting system and allocate them against your Synergy invoices. Using connect you can transfer the payment data from your accounting system, and have the payment created in Synergy and automatically attached to the same invoice number.

Exporting invoice payments:

Create your invoice payments manually in Synergy, as you don't have access to use the accounting system to enter invoice payments. Invoice payments entered in Synergy are allocated to invoices. The next time you run Synergy Connect the payments entered in Synergy will be transferred to your accounting system and allocated to the matching invoice number.
