Automation has transformed tax compliance workflows and supports efficient certificate management
I think as far as improvement with Avalara, we are a manufacturing company, so we have some one-off situations or distributors and things of that nature that aren't very well educated on the tax compliance and so it kind of puts us in a position that when we are requesting different certificates, they don't really understand. For example, Idaho, they know that they can use their Idaho certificate and if they are a reseller, they can use it in all 50 states. However, of course, in Avalara, it doesn't work that way. We have to have certificates, whether it is a multi-state form or individual certificates, for those other areas that shipments may occur to be exempt. Otherwise, it won't recognize it.I think the account executive support could definitely be improved for a business customer.

What needs improvement with Avalara?
Their support team is not responsive and kind of avoids my questions when I'm asking. Definitely upgrading their support system would be appreciated. If the nickel and diming pricing wasn't a conce...
