Sales tax integration for WooCommerce

Calculate rates, prepare returns, and more right from your own ecommerce app.


Avalara’s integration with WooCommerce does the heavy lifting

Improve rate accuracy and reduce returned shipments 

Avalara verifies addresses with rooftop accuracy across more than 12,000 U.S. tax jurisdictions. This ensures tax is applied more accurately than a ZIP code and decreases the chance of wrong delivery.

Easily manage taxability rules across a vast product inventory

Avalara maintains a vast catalog of product taxability rules in order to apply the appropriate tax across thousands of SKUs, accounting for sales tax holiday and tax law changes.

Better assess tax obligations in each state

Avalara's solution tracks your economic nexus tax liabilities in states where you're potentially obligated to collect. Detailed reports will alert you when you're about to trigger tax obligations in new states.

Address the global market with confidence

AAvalara calculates customs duties and import taxes in real time at the point of sale and collects at checkout, reducing the risk of costly penalties, carrier surcharges, customs delays, and customers being surprised with unexpected costs.

Streamline aggregation of omni-channel sales transaction data

Avalara automates the collection of sales transaction data from ecommerce marketplaces and business applications for tax preparation and filing.

Remove the manual drain of filing and remittance

When it’s time to file, you can reconcile a single worksheet and pay one amount for your total tax liability. Avalara works with state and local governments to file and pay on your behalf.

Work with other business systems you already use

With 700+ prebuilt integrations, Avalara’s SaaS-based tax solutions plug into today’s most widely used accounting, ERP, ecommerce, shopping cart, and other applications for a full omni-channel solution. No prebuilt integration available? Build one with advanced APIs.

“Our owner wanted to be compliant, but the volume and complexity were more than we could handle at our size,” says Paul. “It was cheaper to automate, because we didn’t have the resources to handle it all.”

Here’s what some of our 1,100+ WooCommerce users are saying

Being in ecommerce, we have nexus across the US and I have no doubt that we would not be able to keep up with sales tax requirements without Avalara.

We were very clean, post-Avalara, while the period before had lots of problems — paying the wrong amounts, applying the wrong rates, getting item taxability wrong.
