Trade account management

Every account you hold.
One dashboard.

Trade accounts dashboard

Vendors, workrooms, installers, fabric houses. No more unruly Google Sheets, no more digging through emails for an account number, discount code, or your rep's phone number.

Info from 1,700+ to-the-trade vendors is already in Credenza—just start typing and add them to your dashboard in one click.

Your trade relationships are your business. Now they're organized like it.

Certificates attached to accounts

Every certificate attaches to its vendor automatically. When one expires, the affected accounts surface on your dashboard—so you know when it's time to submit a new one.

Vendor logins, securely stored

Account numbers and portal passwords encrypted in transit and at rest. Copy user name and password with one click. Share access with your team; revoke when someone leaves.

Bring your whole book in one import

Upload a CSV of your existing trade accounts—we match against our directory of 1,700+ brands and auto-fill categories, contact info, and portal links. Migrate decades of vendors in minutes.

Update once, update everywhere

New address, new business name, new team member—change it in your profile and every vendor you're connected with sees the update.

Tax strategy & resale certificates

Resale certificates
generated instantly.

Pick the vendor, pick the state, hit generate. Credenza picks the right form and fills every field—firm info, vendor details, tangible goods sold. Every expiration tracked. No wondering what form to use or what box to check.

The broadest exemption you're legally entitled to

Did you know a single registration can earn you tax exemption in dozens of states? Whether you're on a sourcing trip to Round Top or shipping out of state, Credenza finds you the broadest exemption with the fewest possible forms—so you don't pay tax if you don't need to.

Filled in, not guessed at

We auto-fill legal business name, address, and comprehensive product categories from our to-the-trade vendor directory of 1,700+ brands to build you a compliant blanket certificate in seconds.

Always current, never lapsed

Every certificate's expiration date is tracked in your vault. For vendors on Credenza, we notify you before anything lapses—so your tax-exempt status never changes because of a missed deadline.

Bring your own cert

Six states require their own state-issued certificate—AL, FL, LA, NM, TN, WA. Upload yours once—Credenza tracks expirations and keeps it ready to send to any vendor on the Credenza network.

Each person, their own login
No shared passwords to rotate when someone leaves.
Everyone can contribute
Any team member can generate certificates, add vendors and sources, and manage trade accounts.
Not authorized to sign?
Every resale certificate needs a legally authorized signer. Any team member can draft and pre-fill the cert; route it to the firm owner or another authorized signer to complete in their inbox.
