Is there a way to automatically round up items on an invoice?(For easy payment, client would like the final invoice amount to be rounded to the nearest $5 or $10 amount)

Hi there, 

QuickBooks Online is here to help you get paid faster and easier for your products and services. I know how important it is for your customers to pay for their invoices in a way that works for both of you. I'll help shed some light on this.

At this time, the option to automatically round invoice items to the nearest $5 or $10 amount isn't available. I can see how handy that would be, and I'd be happy to submit this feedback to our product engineers. I'd also encourage you to pass these suggestions on to our product development team through the Gear icon > Feedback. We're constantly looking for new ways to improve our products.

If you have any questions or concerns, feel free to ask.

Have a great day!
