Payment Exceptions allow a payment to be made without an actual sale and then, at a later date, a sale to be made without an actual payment.

Typically, this is best handled by using a Clearing Account of some sort in the Other Current Assets section of your balance sheet chart of accounts.  You would not, typically, want to map Payment Exceptions directly to a bank account, as the payments/deposits will come through via the actual payment mechanism (e.g. credit card, cash, etc).

For example, if you accepted a Visa payment today on an order for fulfillment tomorrow, the accounting would be:

Today:
Debit: Visa
Credit: Payment Exceptions Clearing

Tomorrow:
Debit: Payment Exceptions Clearing
Credit: Sales

If you add a new account to handle these in your accounting system, you can refresh your Shogo accounting details and then map to the new account.

Refresh your Reference Data by navigating to:

Settings>Accounting

Select the location you would like to edit

Click Refresh Reference Data 

After your reference data is refreshed, you can map the Payment Exception in the Payments section of the mapping.
