In short: A single creditor model means your company buys from many suppliers but pays only one: a central partner that orders, receives the supplier invoices, pays the suppliers and invoices you, with one digital invoice per purchase order. Your ERP holds one creditor instead of hundreds of small ones, so accounts payable handles far fewer vendor records and payments.
Why small suppliers are expensive to pay
In most large organisations, a small group of strategic suppliers covers the bulk of spend. The long tail is different: hundreds or thousands of suppliers that each receive a few orders a year. Every one of them still needs a vendor record, bank details, a compliance check, invoice matching and a payment run.
The cost of an invoice does not depend on its amount. A €90 invoice from a one-off supplier goes through the same steps as a €90,000 invoice from a contract supplier. That is why tail spend typically generates most of the supplier records and invoices, while representing only a small share of total spend.
How a single creditor model works
- An employee requests or orders a product or service, from any supplier, through one platform.
- The single creditor places the order with the supplier, or sources a supplier for a spot buy.
- The supplier delivers to your company and invoices the single creditor, not you.
- The single creditor checks and pays the supplier.
- You receive one digital invoice per purchase order, with your PO number, through the channel you choose (Peppol or another format).
Your finance team pays one creditor, on agreed payment terms. The suppliers are paid on time by a partner that handles their invoices every day.
Where the savings come from
- Fewer vendor records. New suppliers no longer need to be created, validated and maintained in the ERP. One record replaces them.
- Simpler invoice processing. Every invoice comes from the same creditor, carries your PO number and arrives digitally, so it can be matched automatically instead of checked by hand.
- One payment run. You pay one creditor in your regular payment run, instead of many small transfers to different bank accounts.
- Less compliance work. Supplier checks, VAT handling and document control sit with the single creditor.
- Better visibility. Because every order passes through one channel, all tail spend is reported in one place, by supplier, category and cost centre. See spend visibility.
Single creditor vs. a purchasing card
A purchasing card also reduces invoices, but the spend stays fragmented. Card statements rarely carry the line detail finance needs, VAT recovery depends on receipts collected afterwards, and many suppliers do not accept cards. A single creditor keeps the full order and invoice detail, works with any supplier, and adds sourcing for requests without a known supplier.
When a single creditor model fits
It fits best when your supplier base contains many suppliers with low annual spend, when employees often need one-off purchases outside catalogues, or when your AP team spends more time on small invoices than on strategic ones. Strategic and contracted suppliers stay where they are; the model only takes over the tail.

Frequently asked questions
Is a single creditor the same as a master vendor?
Both mean one vendor for many suppliers. "Single creditor" stresses the finance side: one creditor in your ERP and one invoice flow.
Do we lose contact with our suppliers?
No. You can still choose the supplier; the single creditor only takes over ordering, invoicing and payment.
Does it work with e-invoicing?
Yes. Every invoice is digital and is delivered through Peppol or another channel you choose. See P2P and e-invoicing.
