To sync tax rates between Pool Brain and Quickbooks Online, you must create identical custom tax rates in BOTH programs.
If this is done properly, the tax rates will always be the same on invoices in both programs.
If this isn't done properly, Quickbooks will change the tax rate automatically based on service address location. This can cause discrepancies so it's important to set up your tax rates in both programs with the same exact name and percentage value.
