Yes, you can, Pbarela. Applying for a vendor credit when paying a bill in QuickBooks Online (QBO) is optional and depends on your situation. Let me go over with some details.
Vendor credits are applied to the open bills to reduce the amount you owe from your suppliers. However, if you don't want to use the credit for a particular bill payment, you can delete it. I'll show you how:
Click the +New button
Choose Pay Bills.
Select the Bill you want to pay.
Under Credit Applied, delete the amount.
Then Save.
The credit will remain available in your account and can be used for a future bill or refunded by the vendor, depending on your agreement. Always review your vendor credits periodically to ensure they are accounted for and utilized according to your business needs.
