Here is a guide to creating an Accounts Payable (A/P) Invoice payment in the ERP Module.
Creating the Payment
Once you have an A/P Bill (see: How do I manage A/P bills?), in ERP, go to Accounts Payable > A/P Bill Payments.
Click Add. You can also click Apply to see all existing payments.
Enter in the Vendor # or use the magnifying glass to search for the vendor that will be paid. Click Load All to see all open A/P Bills for this vendor. Below, under the Payments tab, you will see all outstanding A/P Bills for this vendor.
Select the bill or bills you wish you pay to pay the full amount. You can also type the payment amount under the Payment column. You have the option of paying multiple bills at a time, or you can opt to pay a partial amount of the bill. The boxed numbers are the ones included in this payment. You can also see that one of the bills has already been paid in part, under the $ Paid column. The Payment field up above has updated, as well as the value above Total Payment.
Applying Credit
If you have any credits to apply, click on the Credit tab. This will show you all available Vendor Credits, as well as any A/P Deposits. Select the Credit or Deposit (or multiples) you wish to apply to the payment. You can also type in custom amounts under the Apply column. This will update the Unapplied number up top next to whichever type of credit it is. You'll notice, however, that the Total amounts on the right still show $0.
Click the small blue checkmark next to the Credit Amount. The Total Credit will adjust accordingly, and the Unapplied Credit will change to $0 (because the credit has now been applied).
Note: The same rules apply whether this is a Vendor Credit, A/P Deposit, or Other Credit. It is helpful to have them separated this way so that, when syncing with your accounting software, the credits are appropriately categorized into separate GL (General Ledger) accounts.
When you're ready to pay, update the Paid By field, select which Bank Account it's coming from, and hit Save.
Click Yes.
If the selected bill(s) haven't been synced with QuickBooks, this warning will appear. Proceed however you see fit: either sync the bills first or continue anyway.
Your payment has been completed.
