Today is our go live date on Avalara.
I am wondering if anyone out there has a checklist or implementation guideline? Avalara did assign a go live guy, but he does not have any time to discuss for another week. Our shipping broke once we installed the Avalara updates. Our invoicing also did not work anymore, so had to restore from Sage MAS backup. Wondering how I should set up customers and how the software installation should go. Does it usually break everything?
Thanks
Chris
