How do I pay supplier

Hi there, ravi-3dnsolution.

It's nice to see you posting your concern here in QuickBooks Community. I'll share steps to ensure you're able to pay your supplier.

Once you get the bill from a supplier, you'll have to record this first as Purchase Bill in QuickBooks Online. This way, you're able to choose this entry so you can pay the supplier to tag the bill as close.

Here's how to record bill:

1. Click the + New icon.
2. Choose Purchase Bill.
3. From the Supplier dropdown, select a supplier.
4. From the Terms dropdown, select the bill's terms. This is when your supplier expects to be paid.
5. Enter the bill details in the Category details section. From the Category dropdown, select the expense account you use to track expense transactions. Then enter a description. Tip: You can also enter specific products and services in the Item details section to itemize the bill.
6. Enter the Amount and tax.
7. Fill in the other necessary field.
8. Hit Save and close.

Once done, you can now make a pay bill in QuickBooks Online. Please follow the steps below.

1. Select + New.
2. Choose Pay Bills.
3. From the Payment account dropdown, select the account you paid the bill from. For instance, if you paid from your checking account, select checking.
4. If you select a current or savings account, you can enter Reference no. Then, enter the Payment date.
5. Select the checkboxes for the bills you made a payment towards.
6. From the Payment column, enter the amount you paid towards each bill. 
7. When you're done, hit the Save and close.

After that, the selected bills are marked as paid. For additional information, you can refer to this article: Enter bills and record bill payments in QuickBooks Online.
