We often get bills that have tax differences from what Zoho calculates - or has two tax rates? How do we adjust the tax in a bill to match it? We can't make it an expense because we have N30 terms. If we just post direct to Sales Tax Payable account, how will it show on the tax report?

Example; 

Shipping - 1.300

GST - $25     

HST - $55

There is no easy way to do this.
