Hello all,

My firm has a number of distribution facilities throughout the US, in numerous states.

When a shopper locations an order, we have no idea the date and placement of achievement so we wish to show an estimated gross sales tax.

I am how Amazon does issues: it looks like once they group gadgets into shipments, they place a bank card authorization for the *estimated* whole for every cargo.

Earlier than every cargo goes out, Amazon calculates the ultimate gross sales tax and submits an adjusted quantity for seize towards the authorization.

However from [VISA’s docs](https://usa.visa.com/dam/VCOM/international/support-legal/paperwork/best-practices-authorization-and-reversal-processing.pdf) (web page 2), on-line retail will not be an “Eligible Service provider” class for adjusted authorizations.

Does anybody understand how Amazon (or any eCommerce firm with the identical issues as ours) handles this?


Blissful to supply extra info – hope that is sensible!
