Procurement service bus

The Procurement Service Bus (PSB) is a reliable, scalable solution with simple API. The PSB can be integrated white label. E-invoicing has never been this easy and accessible before. eConnect's PSB is the best choice for software packages and corporates!


Advantages of the procurement service bus (psb)

all known e-invoicing networks

Besides standard Peppol, the PSB also gives you direct access to other e-invoicing networks, such as Ariba, Tungsten, Coupa and Tradeshift.

automatic xml transformation

Does the customer need a different format or version than you are able to send? The PSB automatically recognises which transformation is needed to deliver the document.

proactive route detection

E-invoicing without manual setup. We actively check for the existence of the receiving party's Peppol ID.

retry mechanism

If your network is down temporarily, all messages will still be delivered as soon as it's back online, thanks to our retry mechanism. And when recipients' access points are temporarily unavailable, eConnect will continue to retry sending the bill for 48 hours.

REST-API en native push

The PSB is based on the REST API Webservices with OAUTH2 security. The statuses and delivery of documents are transmitted via push messages to the customer's endpoint.


Because of e-return messages, the sender automatically receives notification of a changed invoice status from the invoice recipient.

What do our users say?

❝ With the integration of all messages (including packing slips, orders and invoices) considering the purchase of goods or services exchanged between different networks and standards, we now really have control over the total procurement process from purchase to pay (P2P).❞

Procurement service bus - how does it work?

If you need high-volume processing, eConnect's PSB is the solution! The traceability of each document prevents batch processing and allows real-time tracking of each document. The volume is distributed across at least (in the minimum configuration) five Access Points via reliable queues and is dynamically distributed from the PSB. The infrastructure is scalable at any time, without any noticeable change in service. This means fully automatic and guaranteed delivery, even at high volumes!
