Exposure
Retroactive exposure score
An auditor who flags one error extrapolates it across your entire audit window. We tally your real retroactive dollar liability by state, buyer, and certificate type, so you see the number before they do.
Sales-tax exemption compliance
Exemption Ledger is the system of record for resale and exemption certificates, built for B2B finance teams shipping taxable goods across state lines. We validate every cert against the state you ship to and chase renewals before they lapse, so when an auditor tries to extrapolate one bad form across your whole history, there isn’t one to find.

What auditors look for
Exposure
An auditor who flags one error extrapolates it across your entire audit window. We tally your real retroactive dollar liability by state, buyer, and certificate type, so you see the number before they do.
Evidence
Every certificate is archived with the exact state statute and confidence score behind its verdict. Your CPA reviews the whole trail without a paid seat.
Parsing
Confirms each cert meets the destination state’s specific form requirements, not just that a document was uploaded.
Rules
Thirteen states reject out-of-state certificates outright. Every form is checked against the state you ship to.
Renewals
Expired certs stay live until an auditor catches them. Renewal sequences open months before the form lapses.
Sync
Read-only sync surfaces invalid certs and flips tax-exempt status the moment a cert validates or lapses.
Inside the product
Ten seconds through the real app: total audit exposure, the full certificate ledger, then the exact gate that fails a deficient certificate.

Who it’s for
If you ship taxable goods to exempt buyers across state lines, your certificate database is a liability until every form is validated against the state you ship to. One gap found on audit extrapolates across years of transactions.
