Sales Tax Exemption Certificate Management System ECMS


Valid Exemption Certificates

TTR’s ECMS is much more than simple storage and retrieval of exemption certificates. ECMS’s proprietary Artificial Intelligence (AI) actually “validates” exemption certificates before they get stored in ECMS. Validation is the process of verifying that an exemption certificate is valid. ECMS is the only system that validates your certificates before they get stored. ECMS’s proprietary AI looks at over 80 legal requirements and validation steps to ensure that every certificate is valid.

ECMS has another industry first: Certificate Selection Assistant (CSA). This part of ECMS’s AI smartly gathers information to make sure the correct exemption certificate is selected in the first place. ECMS also boasts the most complete library of available exemption certificates of any provider, including all local and special exemption certificates.

Artificial Intelligence ("AI")

ECMS is the first AI-enabled exemption certificate management system. The AI instantly checks for more than 80 different validation criteria to ensure exemption certificates are valid before they get stored in the ECMS.

The ECMS AI doesn’t stop there. The AI-enabled Certificate Selection Assistant (“CSA”) also ensures that the correct certificate is selected every time. With the assistance of the ECMS AI, you will have confidence that the correct exemption certificate is selected and that each certificate is valid.

One of the most challenging parts of managing exemption certificates is knowing which certificate to use for a particular transaction. With the CSA you'll never be left wondering which certificate to use.

The CSA lets you quickly and accurately find the right exemption certificate for any transaction in any location, for any type of tax -- every time.

Service Organization Control 2 (SOC 2) certification is the strictest independent audit that an organization can receive attesting to the highest standards of data integrity, data security, and data privacy. There is a reason that SOC 2 is recommended by the American Institute of CPAs (AICPA).
