I collect sales tax in two different states, Indiana and Michigan. When I check the taxable customer report for QBO, Taxes -> Sales Tax -> Reports -> Taxable Customer Report; it shows the Tax Rate for all customers as IN (7%). I would think the customers located in MI should show MI (6%).
This is not a problem when I manually enter invoices as the tax is calculated correctly for both states. However, when using a third party invoices app (LaceUp Solutions) it apparently reads from that table (or wherever that table gets it's info) because it wants to set the tax rate for all customers at the IN 7% rate. This causes problems when trying to invoice MI customers from the app.
