No matter the size of a company or the breadth of its products and services, they all need tax software that can bridge disparate and siloed data to manage the tax compliance process end to end. Having reliable APIs is the first step in achieving this goal.

You may also contact customercare@avalara.com to connect with our VP of Customer Excellence, Bobby Sands. Answered: Courtney Wendel-Stevenson on March 5, 2021 There is nothing we haven't had an issue with regarding Avalara. Website goes down randomly, customer support is the worst, wanted to cancel a service, but didn't receive a notice our annual term was up so it auto renewed. We'd had so many problems with them that they credited us for part of the renewal cost. Our only resolution is to learn how do to all of this in house. Answered: Michelle Stone on November 10, 2021 Comment deleted by user. Answered: Joel Barger on July 13, 2022 I canceled on February 20, 2026 and on May 5th, I'm still battling them to confirm cancellation of my account. They've continued to bill me and withdraw money from my account. The most recent ACH was a substantial amount of money and my new provider says the money wasn't deposited into our tax accounts. Avalara reps promise to call back but they haven't. Nobody responds to emails and they avoid taking responsibility.
