Limit Tax Lookup Requests

[danmorin]

The amount you get charged by AvaTax is partly dependent on how many tax rate lookup requests you perform. Because of the way Magento's admin order entry works, there is a potential for the AvaTax integration to make a very large number of lookups which can add up to significant overage costs.

For example, if a customer has a default shipping address or if you enter the shipping address before the products, then the AvaTax integration software will do a lookup request after every individual product is added to the order. It makes another request when shipping is selected or if you update the quantity of a product.

Instead, it would be helpful to tie tax rate lookups to something that only happens once, or a very limited number of times. It could act more like shipping where you click a link near the end to calculate the sales tax. Or it could be tied to selecting a shipping rate, however that may not work for downloadable products. Any way of limiting the number of lookups would be an improvement.

Or you can try to convince Avalara to only charge for actual sales rather than lookups, but that seems like it would be more difficult...

Thanks for the suggestion. We will investigate and try to implement this improvement in our future releases.
