Executive Summary: Payment defaults and delays are no longer a marginal issue, but a structural risk for mid-sized businesses. Studies show that many companies are affected by late payments - with direct consequences for liquidity, financing flexibility, and the stress level of management. Instruments such as trade credit insurance, factoring, and guarantees manage these risks effectively and turn the fear of non-payment into a calculable risk - renz credit & consulting acts as an independent navigator in this landscape.
1. Payment defaults as a real threat - not just a gut feeling
Many business owners know the feeling: revenues look good on paper, but nervousness reigns in the bank account. This feeling is backed by data.
In a 2024 payment experience study by the credit insurer Coface, around 78% of the companies surveyed in Germany stated that they were affected by payment delays. According to the same study, the average delay is around 31 days beyond the agreed payment termThe average duration of payment delays in 2024 was 31 days, after having been around 40 days before the pandemic.
An EOS study on European payment practices also shows how sharply payment behaviour has deteriorated: In Germany, according to the 2025 EOS study, a total of 22% of invoices are not paid on time - 17% are paid late, 5% not at all; in 2022 this figure was still 14%.
At the same time, claims paid by credit insurers are rising significantly: The German Insurance Association (GDV) reports that trade credit and surety insurers are expected to settle claims from payment defaults of almost one billion euros in 2024 - around 25% more than in the previous year. Up to 22,500 corporate insolvencies are expected for 2024, roughly one quarter more than a year earlier.
For business owners, the message is clear: payment defaults are no longer an exception, but a serious structural problem - with a direct impact on corporate liquidity.
2. Why revenue is not the same as liquidity
Revenue is a performance indicator, but liquidity is vital for survival. The difference lies in the timing of the cash inflow.
2.1 A simple numerical example
Imagine a company with annual revenue of €10 million that sells exclusively on account:
- Payment term: 30 days
- Scenario A: Customers pay on average after 30 days
- Scenario B: Customers pay on average after 60 days
- Scenario C: Customers pay after 60 days, 3% of receivables default
Impact on tied-up capital (simplified assumption, 360 days/year):
| Metric | Scenario A: 30 days | Scenario B: 60 days | Scenario C: Delay + 3% default |
|---|---|---|---|
| Annual revenue | €10,000,000 | €10,000,000 | €10,000,000 |
| Average receivables outstanding | approx. €833,000 | approx. €1,667,000 | approx. €1,667,000 |
| Extra liquidity tied up vs. A | - | approx. €834,000 | approx. €834,000 |
| Write-offs on uncollectible receivables | €0 | €0 | €300,000/year |
Key takeaways:
- Doubling the average days sales outstanding (DSO) ties up more than €800,000 in additional capital in receivables.
- When defaults occur on top, they directly affect equity and your credit rating.
This effect becomes even stronger during growth phases: more revenue means more open receivables. Without consistent receivables management, liquidity needs rise disproportionately. Rapid growth without structured financing is often riskier than moderate growth with robust working capital management.
3. When receivables management tips over: Three warning signs
A liquidity squeeze usually announces itself early. These three signals should be taken seriously.
3.1 Warning sign 1: Days sales outstanding (DSO) rise sharply
The most important early warning indicator is an increase in average days sales outstanding (DSO).
The Atradius Payment Practices Barometer, evaluated by FactoPort, shows: In 2024, only 33% of invoices were paid on time - 57% were overdue and 10% were considered uncollectible. In particularly affected sectors such as construction, the average payment duration is well above 80 days.
Internal questions to ask:
- Are our DSO figures rising over several quarters?
- Are there customer segments or countries with particularly long payment terms?
- Are we continuously extending payment terms due to competitive pressure?
3.2 Warning sign 2: Concentration risk with a few major customers
For many mid-sized businesses, liquidity depends heavily on a small number of key customers. If 20-30% of revenue comes from three or four buyers, a default can be existential.
Typical indicators:
- High revenue concentration on a few customers
- Special terms (longer payment periods, higher limits) granted without risk mitigation
- Limit discussions with your house bank because of individual debtors
Without trade credit insurance or factoring, this risk remains fully on your balance sheet.
3.3 Warning sign 3: Rising dunning ratios and write-offs
If dunning notices increase or invoices more frequently require legal collection, this is a clear sign of structural weaknesses in receivables management.
The combination of:
- increasing overdue receivables,
- higher workload in receivables management, and
- more write-offs
not only creates measurable financial strain, but also heightens uncertainty - especially when liquidity buffers are thin.
4. "How many months can a company survive without cash inflow?" - A look at liquidity buffers
The central question, "How long can we survive without incoming payments?" can be approximated empirically.
An analysis by KMU Forschung Austria based on 85,000 annual financial statements shows: Over 50% of small and medium-sized enterprises have liquid funds that last for a maximum of one month - 42% have reserves for up to 14 days, and another 11% for up to one month.
Although these figures cover Austrian SMEs before the pandemic, they clearly illustrate how thin liquidity cushions often are. The situation across the German-speaking mid-market is comparable.
For your company this means: without active management of receivables, payment terms, and risk protection, even a relatively small default or a wave of delays can push you beyond critical thresholds.
5. Professional protection: From fear to active management
Instead of relying solely on dunning and "good customer relationships", companies can now manage risk in a targeted way. Three instruments are central: trade credit insurance, factoring, and guarantees/surety solutions.
5.1 Trade credit insurance: Protection against bad debt losses
Trade credit insurance covers receivables from goods and services against the risk that a customer does not pay - for example due to insolvency or protracted default.
Core elements:
- Credit assessment and limits for your key customers
- Indemnification after a specified delay or default event
- Optional extensions such as cover for insolvency clawbacks or political risks
Typical indemnity levels are 85-90% of the insured receivable, following waiting periods of around 60 or 90 days and a claims assessment.
Benefits for liquidity:
- Protection against large single risks (major customers, export markets)
- Better bank ratings and credit facilities
- Early warning system through limit changes when credit quality deteriorates
Further background and use cases: Protecting trade receivables with trade credit insurance.
5.2 Factoring: Immediate liquidity and risk transfer
With factoring, you sell receivables to a factoring company and obtain liquidity quickly. Depending on the model, the default risk and receivables management are transferred as well.
In a typical arrangement, factoring provides 80-90% of the invoice amount immediately, assumes the default risk in non-recourse ("true") factoring, and often takes over dunning and accounts receivable bookkeeping.
Benefits:
- Immediate liquidity instead of long waiting periods
- Reduction of default risks (with non-recourse factoring)
- Relief for accounting and dunning departments
The factoring market is well established: In 2024, the German factoring industry recorded a turnover volume of around €398.8 billion, with a factoring ratio of 9.3% of GDP; around 106,850 companies used factoring, and 157 providers were active.

Bank guarantees from your house bank usually consume existing credit lines.
Surety bond insurance offers an alternative:
- Guarantees are issued by the insurer
- Bank credit lines remain available
- Liquidity is preserved because no capital is tied up
Depending on credit quality, industry, and term, premiums usually range between 0.5% and 4% of the guarantee amount per year, protecting both bank lines and overdraft facilities.

6. Taking entrepreneurial fear seriously: The emotional side of liquidity
Payment defaults are more than just numbers - they are emotionally draining:
- Worry about paying salaries and wages on time
- Pressure in meetings with banks and investors
- Uncertainty around making new investments
- Potential conflict between sales ("We need the order") and finance ("We carry the risk")
When liquidity is tight, even a short-term payment default can trigger existential fears - even in fundamentally healthy businesses.
The most important step: make the risks visible and manage them systematically - using data (DSO, ageing analysis, scenarios) and clear risk-mitigation strategies.

Frequently Asked Questions
How can I detect a looming liquidity crunch at an early stage?
Watch out for three developments:
- Rising DSO values over several quarters
- More overdue items in the ageing analysis (especially >60 and >90 days)
- More dunning procedures and write-offs on receivables
Also monitor your dependence on individual major customers. If 20-30% of revenue depends on a few debtors, any payment delay can immediately trigger a liquidity squeeze. Trade credit insurance and factoring provide protection and deliver early warning signals through limit decisions and observed payment behaviour.
When does trade credit insurance make sense?
Trade credit insurance is usually worthwhile when:
- You sell on account in a B2B environment
- High receivables or long payment terms are common
- Individual customers account for a large share of revenue (concentration risk)
- You operate internationally or are moving away from lower-risk markets
Credit insurers grant credit limits for your customers and adjust them when credit quality changes - making the policy both an early warning system and a risk transfer mechanism. In addition, insured receivables usually improve your bank rating and have a positive impact on credit lines and terms.
Is factoring just a "last resort" or a long-term tool?
Factoring has long been an established working capital instrument, not a last resort. Industry data shows that the German factoring market reached a high three-digit billion-euro volume in 2024 with more than 100,000 customers - predominantly mid-sized businesses.
Typical use cases:
- Growth financing (rapidly scalable liquidity)
- Relieving the accounting department by outsourcing receivables management
- Smoothing seasonal fluctuations
Whether factoring is suitable on a temporary or permanent basis depends on your business model, margins, customers, and processes - an unbiased assessment is crucial.
Do I lose control of my customer relationships through trade credit insurance or factoring?
No - provided that contracts and processes are clearly defined. With trade credit insurance, you remain the owner of the receivables and continue to manage invoicing and dunning. In the event of a claim, you receive indemnification.
With factoring, it depends on the model:
- In-house factoring: You handle accounting and dunning yourself; factoring serves primarily for financing and risk transfer.
- Full-service factoring: The factor takes over receivables management and dunning in transparent coordination with your sales team.
Crucial point: define in advance, both internally and contractually, how communication and dunning towards customers will be managed - rcc contributes practical project experience here.
How do I find the right combination of trade credit insurance, factoring, and guarantees?
The choice depends on:
- Industry profile and customer structure (share of B2B, exports, public sector)
- Level and duration of receivables
- Growth plans and investment pipeline
- Existing financing and collateral structure
renz credit & consulting analyses these factors with you, compares offers, and develops a tailored solution - ranging from standalone trade credit insurance to combined models (for example, factoring with credit insurance) plus guarantee and purchase financing solutions.
