I'm about to try this module but I have some questions.

1. We are required to charge tax on shipping. Does TaxCloud handle this itself, or just use the settings on the shipping config page?

2.
Note: This implementation currently does not support the coupon functionality within Zen Cart. You will need to make sure that the Discount Coupon module is disabled. (Modules > Order Total > Discount Coupon)
Does this mean that discount coupons will break TaxCloud, or that it will charge them tax based on the initial total instead of the final total? If it's going to overcharge them, I'd rather keep my coupons and refund them the difference.

3.
To assign a Tax Class to a product go to Admin->Catalog->Categories/Products->Dbl click on a category->click on Edit->Assign the appropriate TIC_ID to the product from the Tax Class dropdown
Do we have to manually assign a tax rate to each category or product?? I have over 300 categories.


Thanks! I'm really looking forward to trying this out
