Woocommerce theme with TaxCloud.net or something similar

Can anyone tell me what can be used for calculating the correct sales tax amount based on district/zip/postal code for a woocommerce theme?

Woocommerce has a field for “Local Sales Tax” but you have to manually enter in all the states and re-enter each state with the zip codes tax rate for that area. It would basically take a year to put it all in. And there’s still a chance that some of them wouldn’t be correct when it’s all said and done.

I’ve looked for tons of plugins and woocommerce has not developed a tax cloud that automatically calculates the tax based on the address and postal codes.

I looked at TaxCloud.net and even called them. They said they currently don’t support a way to integrate their API and stuff with woocommerce theme. But said maybe it could be done if you had a developer edit the files and test it.

I need a solution. Calculation the sales tax at a state level does not work because it differs by district in each state. SOMEBODY PLEASE HELP! Days of research and getting nowhere.

BTW. I manually process credit cards, so I basically capture the information that is submitted and then take that information and manually enter it somewhere else. I can’t use my own merchant because I use another companies merchant to process. Long story, but that’s the short of it.

Any suggestions or helpful answers is much appreciated!
