Why is an exemption in CertCapture not working for my customers in Sage 100?


Your customer has an exemption in Avalara CertCapture but the customer's invoices in Sage 100 are still calculating tax.


Avalara CertCapture


  • The customer code on invoices does not include the hyphen symbol.
  • Confirm that certcapture also excludes this symbol in the customer number field. 
  • Sage 100 also applies two zeros to the beginning of the customer code.
    • For example: If the customer code is CUSTOMER in Sage 100, the customer code will be sent to AvaTax as 00CUSTOMER.
  • The customer number field in CertCapture will want to reflect this.
