What is Avalara?
Avalara is the best-known name in sales tax compliance. Its AvaTax engine calculates sales tax in real time across more than 12,000 US jurisdictions, applying hundreds of thousands of taxability rules to each transaction and feeding straight into e-commerce, ERP, and accounting systems. Around that core sit managed returns filing, 1099 management, and CertCapture for exemption certificates. TrustRadius scores it 8.4 out of 10 across 957 reviews. Reviewers praise the automated calculations, the time savings, and the fact that Avalara keeps up with regulation changes for you. The recurring problems are customer service, a dated interface, opaque pricing where everything costs extra, and integration friction with tools like QuickBooks. For growing multi-state sellers it is the industry default for good reason; small single-state businesses should weigh the cost carefully before buying in.

The Bottom Line
Avalara earns a 4.2 out of 5 across 957 reviews, and the split is telling: the product is great, the company is not. Reviewers love the automated calculations, the time savings, and the compliance coverage; they wince at support that can take weeks, an opaque price tag where everything is extra, and integration friction. My verdict: for multi-state sellers, Avalara is the industry default and largely worth it — just budget for the true cost. For single-state or budget-constrained businesses, TaxJar or TaxCloud deliver the automation for a fraction of the commitment and without the support headache.
