Clean.
Certain.
Compliant.

Exemption certificate validation and remediation for multi-state tax professionals.

"We had twelve years of certificates across four shared drives with no validation process and no system. SolidCert processed and sorted everything in under two hours. We went into our state audit completely prepared for the first time."

Director of Tax, Regional Manufacturing Group

Ongoing Monitoring

Stay compliant
after the cleanup.

Once your backlog is remediated, upload your full certificate portfolio and SolidCert monitors it on a recurring basis. Certificates approaching expiry, new customers missing certs, new states — flagged automatically before they become a liability.
