California Nexus - I need to charge sales tax only based on Billling address --> Looking for automation software

[SDeshpande]

For our business model I need to charge sales tax even if the shipping address is out of California

• California, The state, county, and city taxes are origin-based, but any district taxes are destination based.
• The key point is that we must charge State and County taxes based on the billing addres, even if the shipping address is out of state. 

The solution I have looked at, Avalara, HotJar all seem to charge tax based on shipping address. 

Are there any solutions that satisfy the above use case?
