Hi MRH21,

Glad to have you connect with us here. QuickBooks is a powerful program that enables you streamline your work using the powerful features offered in the program. Rest assured, I'll be happy to share more info so you're on the right track. 

The function you've described above isn't available in QuickBooks. You'd have to enter a number that's 0 or greater than 0. I can see the benefit of having this function and I encourage you to send feedback about this to our engineers. You can send feedback by clicking on the Gear icon and looking for Feedback. When it comes to recording the transaction in question, I recommend getting in touch with your accountant for expert advice on how handle the transaction. I'll also leave the question open so other Community members can chime in and share their expert advice. 

Let me know if you have other questions by leaving a comment below. I'll be one message away. 

Did you try to create a "supplier credit" (+NEW - Suppliers - Supplier Credit) or are you trying to create a negative entry as an expense for the supplier?  

Hello

im trying to enter a negative expense to balance a refund a received from a supplier. 
ex: spent 30$ for two parts… needed to return one part and was refunded 10$. Since I enter the expense two weeks ago, and got the refund a few days ago…I need to make the adjustments. Thx for any feedback.
