SolidCert checks every certificate against the rules of the state that issued it, then flags the ones that are expired, incomplete, or invalid — so nothing surprises you when the auditor calls.
Resale · Manufacturing · Agricultural · SST · MTC forms · 45+ states
Most companies don't think about exemption certificates until an audit. By then the expired and missing ones are already assessments. We built SolidCert so you find them first.
Why we built SolidCertTell us what you're dealing with, how many certificates and which states, and we'll show you exactly what SolidCert flags and why.

How it works
Dashboard
Each client, each batch, and the valid, review, and invalid counts, updated the moment a run finishes. No more spreadsheets tracking your other spreadsheets.
| Client | Total | Valid | Review | Status |
|---|---|---|---|---|
| Adler Industrial Supply | 3,412 | 2,618 | 591 | Complete |
| Brennan-Hollis Distributors | 1,855 | 1,240 | 441 | Complete |
| Donnelly & Fitch Group | 4,100 | — | — | Processing |
Validation
A Texas resale certificate and a New York ST-120 don't follow the same rules, so SolidCert checks each one against the state that issued it. Every document comes back with a status and a specific reason code, not a guess.
Output
A three-tab Excel workbook, split into valid, needs review, and invalid, with the reason code, customer, form type, and expiration date on every row. Sorted and ready to work, not another PDF to dig through.
| Customer | Form | State | Reason | Expiry |
|---|---|---|---|---|
| Adler Industrial | TX-01-339 | TX | Resale | 12/31/2027 |
| Brennan-Hollis | NY-ST-120 | NY | Resale | 12/31/2026 |
| Cascade Fab. | SST-F0003 | Multi | Resale | Ongoing |
| Eastern Metal | IL-CRT-61 | IL | Direct Pay | 06/30/2027 |
Ongoing Monitoring
After the cleanup, SolidCert keeps watching. A certificate nearing expiration, a new customer with nothing on file, a state you just started shipping into: you hear about each one before it turns into exposure.
