Feature · Vendor Portal Software

Manage suppliers as well as you manage customers.

Vendor portal software that gives suppliers their own login — and gives your AP side the same care your CRM side gets. Full vendor profiles, bills, payments, W-9s, 1099-NEC, and a vendor portal where suppliers see payment status without emailing you.

Bills, compliance, and portal — one record
The problem

Your AP side is a dumping ground.

Bills land in QuickBooks with no vendor record behind them. W-9s live in a Drive folder no one maintains. 1099 season means six hours of manual digging — every January.

It’s not that AP is hard. It’s that nothing is in the same place as anything else.

1 in 3 small businesses misfiled 1099s last year
Missing W-9s are almost always why.

1099 season: two vendors are missing W-9s. Who knows when they last filed.

The bill exists. The vendor doesn't. Nothing connects to anything.

Does Atlas Equipment have a W-9 on file? Tax deadline is Friday and I can't find it anywhere 😬

Try the Drive folder? Or maybe Tom emailed it to himself when he left 🤷
Friday came. No W-9. Filed without it. Penalty on the way.
Three tools. Zero vendor context.

A bill isn’t just a number. It’s inventory received, books updated, and a supplier kept in the loop.

No re-entry. No chasing. Vendors, accounting, and inventory work off the same record.

Supplier portal software

Supplier portal software — they self-serve, you stop replying to “where’s my payment?”

Every vendor gets a login under your domain. They see delivery receipts, bill status, and payment dates — without sending you an email. Onboarding new suppliers takes 2 minutes: invite, set permissions, done. The “where’s my payment?” thread that runs five times a week stops landing in your inbox.

Common questions

What people ask before they switch.

Vendor records and bills are added directly in PrimeBase. Each vendor record holds contact info, payment terms, and bank details. Bills can be entered manually or are created automatically when a GRN is received — no CSV importer needed for most teams getting started.
One platform. Every supplier relationship.

Stop letting your AP side be the dumping ground.
