How do I post a payment to a supplier account with no bill?

AI generated answer (using internal Slack threads):

In NetSuite, you can post a payment to a supplier account without a bill by using a Vendor Prepayment or a Manual Payment method. Here are the steps for both methods: Vendor Prepayment Method: 1. Create a non-inventory/other charge item called vendor prepayment and have it post to a prepaid purchases account. 2. Add a line to the purchase order for the amount of the overpayment using this item. 3. Directly below, add another line with the same item but with a negative amount and a memo of “prepayment reversal”. 4. Bill and pay the first line. Then when the whole PO is received, bill the actual item lines along with the negative amount to pay the balance less prepayment. Manual Payment Method: 1. For Vendor Bill Payments, you can use a payment method that is not a Check (doesn't increment a check#), and not an EFT (doesn't generate an ACH file). 2. You can just put any value into the Check# box that isn't a number and it will not increment your check numbers. Like “manual-1234” or today's date or something. 3. Alternatively, you can post a Journal entry to Accounts Payable and your checking account. If you put the vendor in the accounts payable line of the JE, it should function like a bill payment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
