I am needing a mod. for a store. I need to be able to charge a "county" and a "city" sales tax to my customers. This needs to be done by basing the rate charges off of the "delivery " address not the purchasers address. Since these rates can change monthly, I need to be able to make the updates via the admin panel. There are several mods that would almost work. They go off of the customers address instead of the delivery address. None of them are for charging city tax though.
If you could give me a quote, I would appreciate it.
