 Sometimes there is a need to pre-pay a vendor for a portion or all of a purchase before the invoice is received.   
From the Accounting Node, go to Payables > AP Entry > Commands > New.  
| 1. | Create an AP record to write the check for the prepayment.  |  
 | 2. | Immediately create a negative AP record to show that the vendor owes you the amount of the prepayment.  The G/L distribution account(s) must be the same as the AP record created in Step 1. |  
 | 3. | When the vendor's invoice arrives, enter it through the job as usual for the full amount.  |  
 | 4. | When checks are selected for payment, select the AP record for the full amount and the AP record for the credit. The system will write the check for the difference. |
