You’ve invested in AP automation. The technology works. The workflow is set up. The team is trained. Invoices are still arriving as email attachments. That’s the problem. And it’s almost always the same problem: your suppliers
Supplier adoption is the most common cause. Larger suppliers with capable IT teams can usually integrate directly. But most supplier bases include many small businesses that don’t have the resources to connect to a new system. Ask them to change how they send invoices and you’ll get polite agreement, followed by no action.
A supplier portal is a branded web page where any supplier can submit an invoice without integrating anything technically. They visit a URL, fill in the invoice details or upload a document, and submit. The invoice lands in the buyer’s workflow, treated the same as any other incoming document.
No. The best portals require no account registration. A supplier gets a link, clicks it, and submits. That removes the biggest barrier: setup friction that stops adoption before it starts.
A supplier portal can accept document uploads as well as manual entry. Suppliers who prefer to attach a PDF can do so. The buyer still receives structured data, the portal or connected digitisation tool handles extraction on the receiving end.
Each buyer gets their own version of the portal, their colours, their language, their contact information. Suppliers see the buyer’s brand, not a third-party platform. That matters for trust, and for adoption rates.
Unimaze Supplier Portal is a white-label web application. Each buyer gets their own URL, branded with their colours, language, and contact information. A supplier receives a link, no account, no password. They click it, fill in their invoice details or upload a document, and submit. They get a confirmation on screen. That’s the full experience from their side.
You can require suppliers to enter a purchase order number before submitting, and control which document types the portal accepts. On the receiving end, the submitted invoice enters the same inbound workflow as anything that arrived over PEPPOL or email. Booking Rules assign the accounting codes, Approver routes it for sign-off, and nothing is treated differently because of how it arrived.
