The Single Creditor Model explained simply: what it is, how it works, the benefits it brings to procurement, and who should consider making the switch.
The Single Creditor Model consolidates all of a company's one-off requirements through a single service provider. Common German synonyms are Einzelkreditoren-Modell, Einzelkreditorenmodell, and Single-Creditor-Modell; in English, it is called the Single Creditor Model. All these terms refer to the same principle.
Instead of setting up a separate creditor for every new supplier, each order runs through the same existing supplier relationship. Procurement sees one point of contact, one creditor number, and one consolidated invoice — how many suppliers actually deliver behind it no longer matters to accounting.
The term doesn't describe a software product — it describes a procurement model. A service provider takes over the commercial processing for requirements that would otherwise each trigger a new supplier, a new review, and a new invoice.
This is what distinguishes the model from a classic framework agreement, which applies to a single supplier and must be renegotiated from scratch for every new requester. The Single Creditor Model, by contrast, stays open to any number of suppliers, including ones the company has never worked with before.
The mechanics behind it are simple. In everyday practice, though, they change a lot. A company sets up the service provider as a creditor once, with a creditor number, a payment agreement, and an invoice template that matches its ERP system. This step happens exactly once.
From that point on, every further one-off requirement runs through exactly this one creditor, regardless of which actual supplier the goods ultimately come from. Nothing else changes.
An example makes this tangible. A department needs a special tool from a manufacturer it has never ordered from before. Previously, this would have triggered new supplier onboarding along with a credit check. Under the Single Creditor Model, the same order runs through the existing creditor, without a new supplier being created in the ERP system.
That's the core idea of the Single Creditor Model: one supplier, one creditor, one consolidated invoice, while agents handle the processing in the background. Pedlar implements this model today for more than 100 companies across the DACH region. The service provider consolidates any number of suppliers behind it, from spare parts dealers to trade show fitters. Nothing more is needed.
For procurement, the visible process barely changes. The department reports a requirement, procurement issues the order, accounting books the invoice. What changes is everything that normally happens in between. Supplier onboarding, credit check, individual approval, and separate invoice review disappear because the creditor already exists. This saving repeats with every single order, not just once at the start.
Invoicing itself changes too. Instead of ten or twenty individual invoices from just as many different suppliers, accounting receives one consolidated invoice, broken down by line item and cost center. The format adapts to the existing approval and coding process rather than replacing it, and accounting reviews one known sender instead of many unknown invoice issuers.
A Single Creditor Model lowers administrative supply chain costs because it concentrates the same fixed costs per order onto a single, already-established creditor. Supplier onboarding, approval, and invoice review don't disappear individually — they just no longer recur for every new provider. The biggest benefit therefore lies not in the purchase price, but in avoiding recurring administrative effort. That's exactly where the real leverage sits.
The effect goes beyond pure process cost savings. 80% of transactions, 30% of volume: procurement effort concentrates exactly where the least value is created. Every individual order ties up buyer capacity in processing.
This takes time away from negotiations, supplier development, and strategic category management. Procurement teams spend, on average, almost three-quarters of their time on operational processing instead of strategic procurement (Deloitte Global CPO Survey 2021). For one-off requirements, this share is often even higher, because every order runs through the same process from scratch.
Consolidate all one-off requirements under one creditor, and this ratio shifts noticeably. No more one-off creditors — one creditor for all one-off requirements, no more supplier onboarding — and accounting reviews one consolidated invoice instead of hundreds of individual receipts.
In practice, that means up to 85% lower process costs per order — the empirical value from implementation across more than 100 companies in the DACH region. The capacity freed up flows back into tasks that actually create value.
Anyone looking to simplify their own indirect procurement processes with a Single Creditor Model doesn't need a system change to do it. A one-time setup is enough. After that, every further one-off requirement runs through the same five steps:
The difference from the classic process lies in step two. No new supplier is created in the system, even if the goods come from an unknown provider. This is exactly what solves the problem where pure process optimization fails. Faster approvals and clearer forms don't help much there.
This also shifts procurement's own role in the process. Instead of reviewing, negotiating, and handling every new request itself, the department reports the requirement and the service provider takes over operational execution. Time for questions, complaints, or special requests still remains, because a fixed point of contact is reachable, instead of starting from scratch with every new case.
For the question of how small orders can be consolidated through a single billing partner, four fundamentally different approaches come into play in everyday procurement practice. They differ mainly in whether they actually avoid supplier onboarding or merely shift the effort elsewhere.
Catalog systems and e-procurement suites consolidate many suppliers onto one interface. This makes the ordering process itself simpler, but the creditor setup remains in place. Every new catalog supplier still needs its own creditor in the ERP, even if the order runs more conveniently.
Framework agreements per supplier reduce negotiation effort for recurring requirements with a known provider. For genuine one-off requirements, this helps little. A spare part available only from one specific manufacturer still needs a new contract and a new creditor.
P-cards or corporate credit cards seem elegant at first, because they bypass the creditor setup at the moment of ordering. The effort doesn't disappear. It just moves into the monthly card statement, where receipts have to be tracked and matched individually.
The Single Creditor Model differs on exactly this point. It avoids supplier onboarding from the outset, because every one-off requirement runs through an already existing creditor. It consolidates invoice review at the same time. On both creditor setup and invoice consolidation, it structurally outperforms the other three approaches. It eliminates the cause instead of dodging the symptoms.
The four approaches can certainly be combined. A catalog system for standard items, supplemented by a Single Creditor Model for the rest, covers both types of requirements without either solution excluding the other.
Not every case fits equally well. The model pays off where many small, irregular orders meet many different suppliers. Typical candidates are spare parts, custom fabrications, and trade show supplies. Special tools, services, and software also count among them — requirements that can't be forced into a catalog.
A simple rule of thumb helps with the assessment: if the number of one-off suppliers grows faster than the ordered volume, administrative effort grows disproportionately to the benefit.
Industrial and manufacturing companies with broad category ranges and many locations are especially affected, because different departments, plants, and cost centers there meet a constantly changing number of one-off suppliers. Special requirements naturally occur more often there than in smaller, more homogeneous organizations.
For standard items with stable demand — office supplies, IT accessories, workplace safety equipment — a catalog system usually remains the better-suited solution. There, the guided ordering process itself is the bottleneck, not the creditor setup. The Single Creditor Model complements such systems rather than replacing them: it takes over exactly the part of demand for which a fixed supplier relationship never pays off.
What's the difference between the Single Creditor Model and the Einzelkreditoren-Modell? None. Both terms describe the same procurement model. Einzelkreditorenmodell and Single-Creditor-Modell are common synonyms, used differently depending on industry and company.
Does the Single Creditor Model replace my existing catalog system? No. The model complements existing catalog solutions. These continue to cover predictable standard demand, while it separately takes over the one-off requirements that can't be forced into a catalog.
How quickly can the model be introduced? Setting it up as a creditor is a one-time, manageable process; after that, every further requirement runs through the same path without additional integration effort.
What happens to existing supplier relationships? Existing, regularly used suppliers remain unchanged, because the model only applies to new, one-off requirements that would otherwise trigger a new creditor.
Does the model also work for services and software? Yes. Services and software run through it too. Alongside physical spare and special parts, they use the same creditor and the same consolidated invoice. The path stays identical.
Who bears the risk if a supplier changes in the background? Nothing changes for procurement, because the service provider holds the relationship with the respective supplier — a change in the background stays invisible to the company's own creditor structure.
Does the introduction require ERP integration? No, it isn't necessary. Requirement, order, and invoice can be handled the classic way, by email; anyone already working with a common procurement system can additionally supplement the path with a punchout integration.
