I have an invoice that is partially paid by a customer and the balance is applied against ad campaign that the customer had. how do I account for that?

Hi there, 

When it comes to managing your income and expenses, QuickBooks is the go-to program that helps make your work easier. I'll be happy to provide more information about recording invoices so you can get back to doing what you love. 

Based on the details you've shared, I see you benefiting more by looking into our feature called Progress Invoicing. This feature enables you to you split an estimate into as many invoices as you need. Instead of asking for full payment at the beginning of the project, you can invoice customers for partial payments. As you complete work, add items from the initial estimate to progress invoices. I encourage you to check out this helpful article for more info on how: Set up and send progress invoices in QuickBooks Online. Give this a try and let me know how you make out. Otherwise, I recommend consulting your accountant so you can get expert advice on how to record transactions such as the one you've described above.

In case you have other questions or if you get stuck, don't hesitate to reach back to me. I'm here to help you achieve your goals and excel with your business.
