Pros

“ECM Pro makes exemption certificate management simple, and tax return filing across multiple states has become much smoother, including getting SST numbers whenever we cross a nexus threshold.”

Prabhat K.

Accounts Payable and Floor Manager

“The learning curve is steep at first, particularly when setting up and connecting AvaTax with ECM Pro — it took real time for our small business team to get fully comfortable with the platform.”

Prabhat K.

Accounts Payable and Floor Manager

“As the accounting lead at CivilGEO, Inc. since October 2022, I've been very happy with the value for money Avalara provides, for a small business like ours, it's far more cost-effective than hiring additional tax staff.”

Prabhat K.

Accounts Payable and Floor Manager

Pros

“Vertex offers a reliable tax engine with strong ERP integration and automation capabilities that help improve accuracy and reduce manual effort.”

Rebecca S.

Sr Tax Technology Analyst

“great products, calculate taxes same time”

Val K.

Tax Manager

Cons

“For tax software, that kind of delay can create real operational headaches. ”

Christina N.

Controller

“What I liked least about Avalara is that, despite its strong automation capabilities, the platform can sometimes feel complex and not very intuitive for new users.”

Mrugen B.

Financial Accounting

“Their entire purpose is to file tax returns accurately and compliantly, yet our filings were submitted incorrectly and non-compliant. When I raised the issue, the team refused to take responsibility or offer a resolution.”
