Startup Idea: Automated Sales Tax Rate Update Software

Startup idea to develop an automated solution to update sales tax rates seamlessly in the billing system. The software would utilize an API and automate the process that's currently done manually, saving accounting personnel several hours.

I am an accountant at a technology firm in Oklahoma. Every time sales tax rates change we have to update them manually in our billing system. If you could make a way to do this automated by using an API that would save hours of time. No we have not we do it manually.
