Business is good, the order books are full. But the bank account is tight at the end of the month. The reason is almost always the same: customers pay in 30, 60 or 90 days, but wages, rent and materials won’t wait. Factoring – also known as invoice factoring or accounts receivable factoring – is one way to bridge that gap. You sell your outstanding invoice and have the money immediately. For many B2B businesses it is a strong solution. For others, a one-off financing fits better.
This article explains how factoring for small businesses works, what it costs, who benefits and when a Sofortfinanzierung is the better choice.
How factoring works
The principle is simple. You issue an invoice to your customer. Instead of waiting, you sell that receivable to a factoring company, the factor. The factor pays you immediately, typically 80 to 90 percent of the invoice amount. The remainder is held back as a security reserve: once your customer has paid, this amount is released to you minus the factoring fee. Depending on the contract, the factor also takes over debt collection and the default risk.
Factoring is not a loan. You are not taking on debt, but selling a receivable that is already yours. How you improve your liquidity depends on the specific problem – factoring is one of several options.
What factoring costs – fees, interest and the all-in model
Invoice factoring costs small businesses typically between 1.8 and 3.7 percent of annual turnover – depending on model, provider and turnover volume. Factoring costs are made up of two core components: the factoring fee covering administration, collections and default protection, and financing costs for the period until customer payment. Debtor credit checks add a further layer of costs.
For small businesses up to around €500,000 annual turnover, the all-in model is common: fee, interest and ancillary costs are bundled into a single percentage. This makes calculation straightforward but provider comparison harder. Anyone seeing separate line items should add all three components together. Most providers also require a minimum annual turnover of €100,000 to €200,000 – below that, the model rarely works economically for the factor.
The factoring fee
The factoring fee covers administration, receivables management and default protection. At competitive providers it runs between 0.1 and 1.5 percent of the invoice amount, depending on turnover volume, industry and customer creditworthiness. Small businesses with high administration cost per invoice pay more than large ones with a clear debtor structure.
The financing costs
Because the factor advances the money, financing costs arise, comparable to the interest on a current-account credit facility. They typically run 3.0 to 5.0 percent per year on the advanced amount and accrue day-exactly for the actual financing period. At a 45-day payment term, that is roughly 45/365 of the annual rate per invoice.
Debtor check costs
Before buying a receivable, the factor checks your customer’s creditworthiness. This costs a flat fee per debtor per year, typically around €20 to €25. With 10 customers, that is €200 to €250 per year, regardless of how many invoices are submitted.
What this means in practice – a sample calculation for a trades business
A painting and decorating business with €400,000 annual turnover, 8 commercial customers, average payment term of 45 days. The business works exclusively in the B2B sector. The calculation below uses the itemised model – anyone receiving an all-in offer will see a single percentage that already covers all three components.
That equals around 2.6 percent of annual turnover. In return the business gets immediate liquidity on all invoices, no debt collection effort, and with open factoring no bad-debt losses. Whether it makes sense depends on how regularly these benefits are used and whether the business profile suits factoring. That is what we look at next.

Open or silent factoring – what is the difference?
Alongside costs, there is a practical question: should my customers know about it? That is exactly what distinguishes open from silent factoring.
Open factoring – your customers know about it
With open factoring your customer is notified that the invoice has been assigned and pays directly to the factor, who also handles debt collection. The key advantage: the factor takes on the default risk. If your customer does not pay, that is the factor’s problem, not yours. For businesses with many customers, high collection workload or variable customer creditworthiness, this is a genuine benefit.
Silent factoring – your customers notice nothing
Silent factoring means: your invoices are sold without your customer finding out. The receivable is assigned but your customer is not told. They continue to pay into your account and you remain their sole point of contact. Suitable for businesses with few, long-standing partners where the relationship matters more than the saved admin. The price is higher because the risk for the factor increases.
What does silent factoring cost more?
Typically 0.3 to 0.8 percentage points more than open factoring. On €400,000 factoring turnover that means €1,200 to €3,200 in additional costs per year, a difference worth factoring into the decision.
True vs. recourse factoring – who carries the risk?
Independent of whether factoring is open or silent, there is a second important distinction: with true factoring (echtes Factoring) the factor takes on the default risk in full. If your customer goes insolvent, that is the factor’s problem. With recourse factoring (unechtes Factoring), the money is advanced to you but if the customer defaults the factor recovers it from you. For small businesses, true factoring is almost always the safer choice – even if it costs a little more.
With the cost framework in view, the key question can now be answered: which businesses is factoring the right tool for?
Who factoring suits – and when a Sofortfinanzierung fits better
Factoring for small businesses is not a universal tool, but built for a specific business profile. Those who match it get a strong solution. Those who do not pay for something that does not fit their needs.
Factoring makes sense when…
The model delivers its full value when long payment terms are part of normal day-to-day business, meaning 45, 60 or 90 days are the rule rather than the exception. Add to that: regularly high individual invoices (average €5,000 or more), clear B2B customers with good creditworthiness, and sufficient turnover volume so that fixed costs do not weigh disproportionately. Factoring is especially valuable for businesses that want to get rid of debt collection or that suffer from slow payers. Open factoring handles both. Typical industries: manufacturing, wholesale, construction, electrical and HVAC businesses with many commercial customers.
A Sofortfinanzierung fits better when…
Factoring requires clear B2B receivables. Businesses with consumer customers – restaurants, retail, hair salons – are simply not accepted by most factoring providers. Project-based services such as those from agencies, consultants or freelancers are also often excluded, because ongoing work does not represent a clear default risk for the factor.
Anyone who only occasionally needs capital – for a new van, machinery or a seasonal gap – pays ongoing factoring costs for something they do not use continuously. That does not add up. The same applies to very small individual invoices, where many providers set minimum thresholds anyway.
In these cases, a Sofortfinanzierung is the cleaner choice: one-off, no contract, no ongoing costs.
The alternative: Sofortfinanzierung or revolving credit line
With the Banxware Sofortfinanzierung you apply for €1,000 to €250,000 fully digitally in a few minutes. After approval, the funds are disbursed within 24 hours. There is a single fixed financing fee, no ongoing interest, no debtor check costs, no annual contract. The capital is freely usable, whether for an investment, bridging the gap between job completion and payment, or a short-term cash shortfall. Requirements: company registered in Germany, at least six months of revenue history on a business account, average monthly revenue of at least €1,250.
For those looking for a fast digital alternative to the traditional bank, the Sofortfinanzierung offers a genuine option without lengthy application processes.
For larger investments and ongoing flexible capital needs above €250,000, the HVB FlexFinanzierung is available as a revolving credit line of up to €5 million. That is the right solution for businesses that need not a one-off but continuous flexible access to capital.

Conclusion
Factoring for small businesses is a strong tool – but only for businesses with regular high B2B invoices, long payment terms and a desire to hand off debt collection and default risk. Those who match this profile get real value from it.
Those who occasionally need capital, have consumer customers or work on a project basis are better served by a one-off Sofortfinanzierung or a flexible credit line: no contract, no fixed costs, no debtor structure required.
