How do I process a 'receive payment' for one total amount that is from two different customers

Hello jcooper-wwotc-ca,

Thanks for joining us here in the QuickBooks Community. I see you've chosen QuickBooks Online as the product you're using, and I hope that it's meeting your needs and simplifying the process of managing a set of business books. It looks like you've gotten to know the Receive payment feature for customer invoice payments, and I'd be happy to elaborate on it for you so you know how to move forward with your situation.

QuickBooks Online is designed to keep things as straightforward and organized as possible, so when it comes to things like customer payments against an invoice, the Receive payment feature works with one customer at a time. As you've probably noticed, the window where you can select invoices and enter payment details has a Customer drop-down menu, which gives you the opportunity to choose one customer and there isn't the option to choose more.

Given that, while you can apply a single customer payment against multiple of that same customer's invoices, you cannot group together payments for multiple customers into a single payment using this feature. You can learn more about the feature here: Record invoice payments in QuickBooks Online

In this case, you'll want to record the customer payments separately. Choose the first customer, then the invoice the payment applies to, fill out the details as needed, and save. You can even choose Save and new to more easily move on to repeating those steps with the second customer.

Feel free to share more about why you're looking to record a single Receive payment transaction for two customers if you'd like. With a better sense of what you're looking to do, I can see if there's another solution for you.

Wishing you the best!
