Digitise your purchasing. Simplify supplier collaboration.
Centralise your purchasing processes and supplier exchanges in a B2B portal tailored to your organisation. From purchase request to order and invoice processing, Weexa helps you digitise your P2P and S2P journeys.
One portal to streamline your purchasing process
Bring your purchasing processes and supplier exchanges together in a single environment. Drawing on its expertise in integration and B2B data flows, Weexa connects your portal to your suppliers, business applications and IT systems – and makes it easy for your teams to adopt.

Centralise your purchasing
Bring requests, orders, documents and communications together in one portal.

From requirement to payment,
digitise every step
The Procure-to-Pay process covers the entire operational purchasing cycle, from identifying a requirement through to invoice processing and payment. A procurement portal centralises these steps and streamlines exchanges between your internal teams, your suppliers and your IT systems.


Go further with a Source-to-Pay approach
Source-to-Pay extends digitisation beyond Procure-to-Pay by covering the steps that come before the purchase. The aim: a better-structured supplier journey with continuity all the way through to payment.
Depending on your organisation and environment, Weexa helps you define the right scope – from Procure-to-Pay to a broader Source-to-Pay approach.

FAQ
Your questions answered
Find answers to frequently asked questions about our procurement portals.
What is a procurement portal?
A procurement portal centralises exchanges and processes between a business, its internal teams and its suppliers. It digitises the different stages of the purchasing cycle, from purchase request to order, goods receipt, invoicing and tracking.
What is the difference between P2P and S2P?
Procure-to-Pay (P2P) mainly covers the process from purchase request through to supplier payment. Source-to-Pay (S2P) has a broader scope, also covering upstream steps such as sourcing, supplier selection and contracting.
Which processes can a procurement portal automate?
A procurement portal can automate purchase requests, approval workflows, orders, supplier communications, goods receipts, invoice matching and status tracking. Workflows can be tailored to your company’s own rules and processes.
Can a procurement portal be connected to an ERP?
Yes. The portal can be integrated with an ERP, accounting software or other business applications using APIs, EDI flows or connectors, so data flows automatically between the portal and your existing IT systems.
How does a procurement portal work with e-invoicing?
The portal can connect your purchasing process to e-invoicing flows, ensuring continuity between orders, goods receipts and invoices. This makes checks, data matching and supplier invoice tracking easier.
