Hi, How do i record PDC payment on supplier bills in QB online?

It's nice to see a new face here, finance-pivotelm. Let me share the steps to help you record PDC payments on supplier bills.

We can create a Cheque to record your post-dated checks in QuickBooks Online. It will allow the system to recognize the cheque as an expense. Thus, it associates the PDC payment to your supplier as you no longer have access to the money. 

Here's how:

1. Go to the +New button and select Cheque under Suppliers.
2. Choose the supplier from the Payee dropdown ▼.
3. On the Bank account dropdown ▼, pick the account the cheque withdraws money from.
4. In the Category details, choose Accounts Payable and then complete the fields.
5. Select Save and close to close the check window.

Please note that using an A/P account will create a credit for your vendor. You'll need to create or open the bill to zero out the balance. Once done, link the Bill and Cheque on the Bill Payment window.
