Vendor portal template for supplier collaboration

Let suppliers update catalogs, confirm POs, and submit invoices against your procurement process. This vendor portal template is built for supplier self-service—not employee SSO—so AP and procurement reduce email back-and-forth.

FAQ

Can vendors see other suppliers’ pricing?

No. Vendor accounts are strictly isolated to their own POs, invoices, and documents.

What if a vendor proposes a PO change?

Acknowledgments can include change requests that procurement must accept before the PO updates.

How do expired insurance certificates get handled?

Compliance docs track expiry and can block new POs until a valid certificate is uploaded.

Does AP still do three-way match?

Vendor invoices feed your match process against PO and receipt data from procurement systems.
