We believe you shouldn't have to understand sales tax to get it right.
The world changed in 2018. The Wayfair decision ended the physical presence requirement for sales tax, pushing enterprise-level complexity onto growing businesses, worldwide.
Businesses found themselves with three terrible options:
Ignore it and risk liabilities worth 5-10% of revenue
Hire consultants who charge enterprise prices
Buy software that still requires you to be a tax expert to operate it
We didn’t set out to build another sales tax tool the world doesn’t need another one. We built Zamp to own the work and the outcome, and we stand behind both — so your team doesn’t have to.
