A supplier of personal protective equipment charges the same sales tax for all purchases regardless of total. How do I enter this as it is not a percentage?

Hi info-neurosparkp,

Welcome to Community!  Entering your transactions with the applicable sales tax in QuickBooks Online is vital, to ensure accuracy when it comes to year end.  In this situation, it's best to reach out to your accountant for their expertise and the best course of action.  If you don't have an accountant, you can follow this link to locate a ProAdvisor in your local area.

If you have any other questions, feel free to reach back out.  We'd be happy to help!
