What the single creditor model is, how it consolidates small orders through a single billing partner, and what it does for the administrative costs of the supply chain.

Open your creditor master data and filter for creditors with exactly one order last year. In mid-sized companies and corporate groups with many small orders, such entries pile up, each needed exactly once, each triggering a full procurement process: supplier onboarding, invoice verification, payment run. For small orders under €1,000, these process costs can exceed the value of the goods.
The single creditor model exists for this problem. This article explains the term and the mechanics, compares the five strategies for consolidating small orders, and shows what the model does for the administrative costs of the supply chain. It ends with a self-assessment using your own figures.
Definition: The single creditor model (also single-creditor or 1-creditor model, in German Einzelkreditorenmodell) bundles one-off requirements, C-parts and small orders through a single creditor set up once in the ERP system. Order, payment and invoice run through this one billing partner; delivery comes directly from the provider. The number of actual providers stays the same; the creditor master data holds one invoicing party for these requirements. In German it is occasionally called Einzelgläubiger-Modell.
Three terms are regularly conflated around this model, and the distinction determines whether the most common objection to it, dependence on a single supplier, applies at all:
The single creditor model is creditor consolidation, not supplier consolidation and not a single-source strategy. A company ordering from a hundred different providers today will still do so tomorrow; what gets consolidated is the invoicing route, not the source of supply. No dependence on a single supplier arises. This distinction is the foundation of the model Pedlar operates as a managed service.
Tail spend refers to the many small, irregular orders at the end of the spend distribution: many transactions, a small share of purchasing volume. Our foundational article on tail spend management covers the causes and how to control it.
The cost lies less in the purchase price than in the process. Every new provider triggers supplier onboarding with checks and manual coordination, the creditor master data grows with every one-off requirement, and accounts payable verifies invoices from invoicing parties that never appear again. Our article on the blind spot of one-off requirements examines why they are systematically overlooked.
Pedlar is set up once as a creditor in your ERP system and then stands at the end of every ordering transaction. Operated as a managed service, the model runs in five steps; the details are on our 1-creditor model page:
The workflow remains your familiar ordering process. The only new element: the same creditor sits at the other end every time, one creditor instead of a hundred one-off creditors. No waiting times: Pedlar handles requests within 24 hours, with a personal contact instead of a ticket system.
For context: tail spend management is the overarching strategy of bundling irregular small purchases and handling them more efficiently; the single creditor model is its operational implementation. Our guide to managing tail spend through a single creditor describes what this looks like in practice.
In this model, consolidating small orders does not mean collecting requirements, postponing them or forcing them into a catalog. What gets consolidated is the billing. However many providers deliver, Pedlar is the single billing partner across the entire order-to-pay process. Every order goes to the same creditor, every payment to the same recipient.
100+ companies process their one-off requirements through Pedlar, across all of indirect procurement: spare parts, tools, laboratory supplies, operating and office equipment, IT accessories, protective equipment, technical operating supplies (MRO), services and software.
Consolidating small orders through a single billing partner is one of five established strategies. They differ in what gets consolidated: requirements, invoices, terms, ordering channels or creditors. Each has a legitimate purpose and a clear limit:
These strategies are not mutually exclusive; they address different segments of procurement. In practice, the combination proves its worth: catalog and procurement platform for standard requirements, Pedlar for the one-off requirements outside the catalog. Together, the two approaches cover close to 100% of indirect procurement. Our overview of tail spend management providers explains what to look for when evaluating an external partner.
With small orders, the administrative costs of the supply chain arise not in the shopping basket but in the processes around it: supplier onboarding, master data maintenance, order processing, invoice verification, payment runs, archiving. A single creditor model targets exactly these:
Administrative supply chain costs therefore fall at every stage of the order-to-pay process, from the master data record to the payment run. The Witzenmann case makes that concrete: process costs for one-off requirements fell from €42,000 to €6,300 a year, a reduction of 85% per order. The manufacturer runs around 300 one-off orders a year through Pedlar as its single creditor; before the switch, each transaction cost around €140 internally. Measured against the service costs, that gives an ROI of 3.3.
Maverick buying, ordering outside the regular procurement process, does not arise from ill will but because the official route is too cumbersome. When a small order triggers supplier onboarding involving several people, the requester looks for the faster route.
The single creditor model reduces this off-process buying structurally: Pedlar provides a fast channel that still stays within your compliance rules. Every one-off requirement runs as a normal ERP purchase order, auditable and with audit-proof documentation of the individual transactions.
Whether the single creditor model pays off for your company can be checked with a simple spend analysis. Five metrics are enough for the self-assessment:
The more one-off orders per year, the greater the effect. The model is aimed at companies that regularly procure one-off requirements and C-parts and set up a new supplier each time: from mid-sized companies to corporate groups, especially with ERP systems such as SAP. It works best on non-catalog items and services, decentralized requests from business departments, and occasional purchases whose process costs exceed the value of the goods.
No. Pedlar is neither software nor a platform, but a managed service. The only change: Pedlar is set up once as a creditor in your ERP system. After that you order as usual; no integration, maintenance or training is involved. Release levels, budget limits and approval workflows remain in place.
Indirect procurement processes become simpler in three places. First: instead of a new supplier for every one-off requirement, you set up one creditor and handle any number of requirements with many providers through it. Second: Pedlar takes over the administrative processing, from obtaining quotes through ordering to invoice handling. Third: the end result is one consolidated, auditable invoice instead of invoices from an ever-growing list of creditors.
No. The single creditor model is creditor consolidation, not a single-source strategy: the number of actual providers stays the same. You still decide which provider to order from; Pedlar handles the administrative processing. What gets consolidated is the invoicing route, not the source of supply, and every individual transaction remains documented and traceable.
No, nothing changes in your negotiating position. Negotiation and category strategy remain the job of your strategic procurement team, and you still decide which provider to order from. The single creditor model changes the processing, not the purchasing strategy: handling one-off purchases was never where negotiation wins were made.
No, it complements both. Standard requirements stay in your catalog and your procurement platform; the one-off requirements outside them run through Pedlar. Together, the two approaches cover close to 100% of indirect procurement, without changing your existing ordering channels for standard requirements.
With Pedlar there are no fixed costs and no minimum volumes. The price is charged per order and depends on the order value. For the business case, you compare Pedlar's service costs with your internal process costs per order; at Witzenmann, this calculation produced an ROI of 3.3.
