We're having a little bit of a 'bug' issue. Though it might not be a bug at all.
Occasionally, GP doesn't calculate tax. None at all. The settings all seem correct (base on customer, customer is setup correctly). The only way to fix is to copy from one document (one without tax) to a new one. The new one then calculates the tax.
I know there are so many variables...but any ideas why this happens?
