Sandbox testing window

The AvaTax release schedule includes a preview period during which time the latest software is available for integration testing in the AvaTax Sandbox Environment two weeks before launching to production. If your engineering team would like a sandbox account for integration testing purposes:

  • Development and Solutions Partners (DSP), please contact your Business Development Manager.
  • Avalara customers, please contact your Customer Account Manager or open a support ticket.

No release for November

Every year, in preparation for Cyber Week, our highest traffic-volume time, we freeze our code for a one-month period to ensure our infrastructure can provide the fastest and most reliable calculation, and help our customers achieve a successful holiday season.

This year, Black Friday is November 29, and Cyber Monday is December 2.  This makes the current release — our October release — the last release prior to Cyber Week. We will skip our monthly release for November.

See you all again in December!
