Why tail spend breaks your P2P process

Purchase-to-pay systems work well for catalogue and contract suppliers. Tail spend falls outside: new vendors, PDF or paper invoices, missing PO numbers and manual matching. Spot Buy Center closes that gap by placing one single creditor between you and those suppliers.

The P2P flow for tail spend

  1. Purchase request in your ERP or in our software.
  2. Approval according to your own rules.
  3. PO and order to the supplier by Spot Buy Center.
  4. Delivery follow-up and supplier invoice check.
  5. One digital invoice with your PO number, sent through your preferred channel.
  6. Payment to one creditor on your terms.

E-invoicing and Peppol

Since 1 January 2026 structured e-invoicing is mandatory for domestic B2B transactions in Belgium, with Peppol as the main network. Many small suppliers are not ready. Through Spot Buy Center you receive structured digital invoices regardless of how the supplier invoices us. We support channels such as Peppol, cXML, OCI and EDI.

Integration

Spot Buy Center connects to your ERP or purchase-to-pay suite, or runs as a stand-alone cloud solution. See our software and how finance teams use it.

P2P and e-invoicing: frequently asked questions

Is e-invoicing mandatory in Belgium?

Yes. Since 1 January 2026 domestic B2B invoices between Belgian VAT-registered companies must be structured e-invoices, with Peppol as the main exchange network.

Our small suppliers cannot send e-invoices. What now?

They invoice Spot Buy Center. You receive one structured digital invoice per order from us, with your PO number.

Which formats and channels do you support?

Digital invoices through your preferred channel, including Peppol, cXML, OCI and EDI.

Do we need new software?

No. You can keep your ERP or P2P suite and connect it, or use our cloud software on its own.

Does P2P automation also cover one-time purchases?

Yes. That is the point: one-time and non-catalogue purchases follow the same digital flow without creating a new vendor.
