Ok I am a programmer, not an accountant.
I am in the USA and I have to collect Sales Tax.
All of my sales are from my website running osCommerce.
It correctly collects sales tax based upon the delivery address.
I do not see how that can be implemented in FA.
I do see Addng a Customer Account and then Adding a Customer Branch, but there it seems I would need to know what the Tax rates is for each customer.
The tax collected is State (6%) and then an optional County (0% to 1.5% surcharge)
Since my long term goal is to have osCommerce feed sales and customer information to FA maybe my answer is to use the osc tax name (FL - Pasco) as a tax group name and be able to look that up when a customer is created. (Florida has 60+ counties!)
Are the Customer Branches basically SHIPPING Addresses that customer uses?
