QB is not matching up payments to the invoice that it is for. I have multiple invoices for the same amount so I don't know which one it is...

If you receive invoice payments to Undeposited Funds first, then make Bank Deposits in QBO that match the deposit amounts that come into your bank feed each day, you will avoid this problem.

If you create a number of invoices for the same amount and receive multiple invoice payments per day, you should not receive your invoice payments directly to your bank account.  

I have a similar issue - collecting multiple rents for the same amount which (if paid on time) would arrive in my account on the same/similar days. I receive the email notifiying me who has paid, but is there an easier way to match a deposit in QBO? For example, if three tenants owe $1000, but only two paid on time, how can I easily trace which two paid? (Without looking back at my emails from a week ago). Thanks in advance for your help!

Glad to have you back, @BlackFoxProperties.

I can get you pointed in the right direction so you'll be able to determine the owner of the payment that was deposited into your account.

In situations like this, I'd recommend getting in touch with our Merchant Services Department. This team is the best resource for such inquiries as they're able to pull your account while the Community is a public space. 

Once they have the information needed, they'll be able to identify the owner of the payment. This way, you can match your transactions properly according to the amount received.

I've also added here some references about matching transactions in QuickBooks Online:

• Download, match, and categorize your bank transactions in QuickBooks Online
• How to Use the Undeposited Funds Account to Receive Payments in QuickBooks Online

This should get you covered today.

Please know that I'm always here to help should you need anything else concerning payments or any QuickBooks related thing. Wishing you and your business continued success!

My contractors do not always pay the invoice in full in one payment.  When I receive the payment do I let QB default check the invoice box?  

Good afternoon, @TCI1-PC.

Thank you for joining this thread. I'd be happy to provide info with applying partial payments to an invoice.

First, you'd want to manually select the invoice when receiving and applying payments to the invoice.

In the Recieve Payment window, choose the customer, and a list of invoices will appear. Click on the invoices you'd like to apply the partial payment to, and when you're ready, go to Save and Close or Save and Send.

For more information about applying partial payments to an invoice, refer back to this detailed article: How can I record a customer's partial payment to an invoice?
