Wholesale buyers hand you tax-exemption certificates — and you carry the audit liability if one is missing, expired, or invalid. ExemptGuard is the audit-insurance layer that collects, OCR-reads, validates, and auto-renews them. It sits beside your existing tax engine, not on top of it.
Multi-state MTC / SSUTA format + expiry checks flag an invalid or expired certificate before an auditor does.
Certificates lapse. ExemptGuard emails the buyer to renew on a ladder you set — the recurring protection.
One click hands your auditor a print-ready register: every certificate, its status, and a full trail.
