We are setting up an online store in X-Cart 4.4.4. We want to use StrikeIron Sales and Use Tax Basic ([url removed, login to view]) to calculate taxes for all purchases in the USA. We are using the "one page AJAX checkout" on our site and would like to calculate tax when the address is entered and a shipping method is selected.
Check out the site here: [url removed, login to view]
I will supply all information needed; admin login for X-Cart, sample PHP and XML code from StrikeIron, etc. Whatever you need.
We need this done as soon as possible. Please feel free to ask any questions before bidding. I am the site administrator.
