tax calculations and address validation IS-U

[Former Member]

We’re looking to change our software that we use to
calculate sales/use tax and address validation. 

Any recommendations?  We need something that is
compatible with our IS-U / FI-CA.

I haven't had to use sales tax with IS-U but in other jobs this was always done using Vertex - see their site here Search | Vertex, Inc.

Hey Randy,

We use vertex O series  for tax, and Trillium for address validation.
