In B2B e-commerce, purchase on account plays a central role as the most popular payment method for business customers. Unlike in the B2C sector, companies often rely on larger order quantitiesandlonger payment terms reliant on optimizing their liquidity and cash flow. The targeted purchase on account not only offers flexibility and trust but also efficient transaction processing, enabling business customers to place orders quickly without immediate payment.
In this context, purchase on account becomes a decisive success factor for B2B companies that want to offer their customers a convenient and secure payment option. In this article, we will cover all aspects, information, advantages and disadvantages, as well as the currently best solution and payment providers for Europe.
B2B Invoice Purchase Providers & Solution: The Most Important Payment Method in B2B E-Commerce

What does purchase on account mean in B2B?
Purchase on account is the most popular payment method in Germany – not only for private individuals but also for companies. With invoice purchase, also known as invoice payment, the buyer receives goods or services immediately and only pays for them later. This provides companies with more liquidity and optimizes cash flow. The payment term varies and is usually determined by the invoice purchase provider. B2B invoice purchase does not differ in principle from the B2C sector. However, the background process is significantly more complex due to legal circumstances and often higher amounts.
Main advantage in a nutshell: With purchase on account, the buyer receives the ordered goods or services immediately and settles the invoice at a later date. However, if the seller uses a payment service provider, they also receive the money immediately! A win-win situation for both sides.
Special challenges in the B2B segment for purchase on account
In B2B, purchase on account still poses a particular challenge. Most B2B companies have a smaller customer base than B2C providers. Since fewer orders are received, B2B providers are all the more dependent on timely payment. B2B purchase on account usually entails a higher risk for the provider because the sums to be paid are significantly higher.
On average, the value of B2B invoices is 1,900 Euros in 2024.
However, if an online payment provider takes over, the receivables management shifts from the provider to the so-called factoring provider.

Risk management and credit assessment
Should the customer file for insolvency after completing a purchase on account, it is unlikely that the invoice will be settled at all. Any potential payment involves considerable effort, long waiting times, and high legal costs. Therefore, it is important for B2B providers to check the company’s creditworthiness in advance. Only after a successful check can the purchase be completed and the goods delivered. This is exactly what B2B payment providers, as we will introduce later in the article, do!

Important definitions for invoice purchasing, factoring, and receivables management:
Factoring is a financial service in which a company sells its outstanding receivables to a factoring company (the so-called factor). In return, the company receives immediate liquidity without having to wait for customer payments. Factoring serves to improve liquidity and can minimize the risk of payment defaults.
Receivables Management encompasses all measures a company takes to collect outstanding invoices and claims from customers. It begins with invoicing, includes dunning and debt collection, and aims to secure liquidity and minimize payment defaults. Effective receivables management helps to accelerate incoming payments and improve the company’s financial stability.
How does factoring / receivables management work?
- Sale of the receivable:
The company sells its receivables (outstanding invoices) to the factoring company. This often happens at a certain percentage of the invoice amount (e.g., 90-95%). - Immediate payment:
The factoring company usually pays the company the agreed percentage of the receivable amount within 24 to 48 hours. This immediately improves the company’s liquidity. - Collection of the receivable:
The factoring company takes over the collection, i.e., collecting the receivables from the company’s customer. The customer now pays directly to the factor. - Final payment:
Once the company’s customer has fully paid the invoice, the company receives the remaining amount minus a fee that the factoring company retains for its service.
Types of Factoring
- True Factoring (with default protection):
With true factoring, the factor assumes the risk of payment default. Should the customer not pay, the factoring company bears the risk. The company is thus protected against payment defaults. - Untrue Factoring (without default protection):
With untrue factoring, the risk of payment default remains with the company. Should the customer not pay, the company must reimburse the factoring company for the sum. - Open vs. Silent Factoring:
Open Factoring: The customer knows that the receivable has been sold to a factoring company, as this is noted on the invoice.
Silent Factoring: The customer is not informed that the receivable has been sold. The company collects the receivable in its own name, while the factoring company remains in the background.
Advantages of Factoring
- Improved liquidity: The company receives money immediately and does not have to wait for customer payments.
- Risk hedging: With true factoring, the company is protected against payment defaults.
- Relief of receivables management: The factoring company takes over debt collection and dunning.
- Better planning predictability: The immediate inflow of liquidity simplifies the company’s financial planning.
Disadvantages of Factoring
- Costs: Factoring involves fees that can reduce a company's profit. -> can be charged extra to the customer upon purchase!
- Dependency: Companies that regularly use factoring could become dependent on quick liquidity.
- Restrictions: Not all receivables are suitable for factoring, e.g., with uncertain customers or long payment terms. Therefore, credit checks are performed online in real time.
Factoring is a helpful financing instrument to improve a company’s liquidity and reduce the risk of default. It is particularly suitable for companies that have long payment terms and need quick liquidity to continue growing or cover their ongoing costs.
Here too, BILLIE with Mollie perfectly steps in and enables the best liquidity with efficient processing and maximum digitalization.
