Avalara for Tax Calculations for Dynamics GP North America

What is “sales tax nexus”? And what are the NEW rules for collecting USA state and local taxes for remote sales from Canada to the USA?

Talk to Endeavour and our preferred partner Avalara. There are a number of 2018-2019, and 2020-2024 key changes in USA state and local sales tax calculations which we expect to impact a significant number of our Canadian and USA clients selling into and across the USA.  Yes both Canadian and USA companies are potentially impacted.

Jan 15, 2022 - Avalara (tax system for GP) proposes to stop support for TLS 1.0 as of March 31, 2022 via their Production RESTv2 API. There is a work around to extend to Dec 31st, then all is decommissioned. . See similar TLS issue with Office 365 and GP.

Contact us to talk about pricing options. Happy to set up a more detailed discussion and even a demo with an expert Avalara consultant when the time comes. At a high level Avalara is SaaS based and charges a fee per 'tax calculation quote', similar to a fee per transaction. This makes it a lot of affordable for small and mid-sized clients.
