Working capital is a company's lifeline – without it, business literally grinds to a halt. As an entrepreneur, I have seen numerous situations where a profitable company has run into trouble simply because working capital was insufficient to cover daily expenses when payments were delayed. According to the Bank of Finland's recent survey, 58% of SMEs consider working capital adequacy their biggest financing challenge in 2025.
What Is Working Capital Financing?
Working capital financing refers to all financing forms used by a company to fund its daily operational activities. It covers payroll, raw material purchases, rent, and other running costs that arise before customers pay for products or services.
The need for working capital arises from the gap between sales revenue and expenses. In a typical Finnish SME, this gap is 30–60 days, but in the construction industry, for example, it can be as much as 90–120 days. The longer the gap, the greater the working capital need.
According to Statistics Finland, the average working capital turnover period for Finnish SMEs is 42 days. This means that a company with annual revenue of one million euros has an average of approximately EUR 115,000 tied up in working capital.
Forms of Working Capital Financing
There are several forms of working capital financing on the market, and making the right choice requires understanding your own company's needs. In my own business, I have tried several options and found that every entrepreneur should be familiar with at least these basic forms.
1. Credit Facility (Overdraft)
A credit facility is a flexible credit option granted by a bank, where the company has an agreed maximum amount of funds available. Interest is paid only on the utilized portion. A credit facility is best suited for short-term and recurring working capital needs where the cash requirement varies monthly.
Credit facility features:
- Interest 4–8% p.a. on the utilized portion
- Facility size typically EUR 10,000–500,000 for SMEs
- Often requires a floating charge or personal guarantee
- Application process takes 2–4 weeks
- Particularly suited for seasonal fluctuations and unexpected needs
2. Invoice Financing
In invoice financing, the company sells its accounts receivable to a finance company and receives 80–95% of the invoice value within 24 hours. The financing amount grows automatically in line with revenue, making it a particularly good option for growth companies.
Invoice financing features:
- Service fee 1–3% of the invoice value
- Funds in your account within 24 hours
- No separate collateral required – the invoice itself is the collateral
- Suits B2B companies with long payment terms
- Financing amount scales with revenue

3. Merchant Financing and Purchase Invoice Financing
In merchant financing, the finance company pays the company's purchase invoices to suppliers early, and the company pays the financier on extended terms. This frees up cash and can generate savings through early payment discounts. Wholesale trade and import businesses in particular benefit from this model.
4. Finnvera Guarantees
Finnvera can guarantee an SME's working capital loan, facilitating bank financing and lowering the interest rate. A Finnvera guarantee typically covers 50–80% of the loan amount. In 2025, Finnvera granted working capital financing totalling EUR 1.2 billion to SMEs.
Working Capital Financing Comparison
The comparison below helps illustrate the differences between financing forms. I have compiled the key factors that influence the choice of financing form based on my own experiences and client discussions.
How to Choose the Right Working Capital Financing?
Choosing the right working capital financing depends on several factors. As an entrepreneur, I have learned that the most important thing is to understand your own cash flow profile and compare actual total costs rather than just the interest rate or service fee.
Selection criteria:
- Cash flow cyclicality – is the need continuous or seasonal?
- Speed of financing – how quickly are the funds needed?
- Total cost – consider all fees, not just the interest rate
- Collateral situation – do you have collateral to offer or not?
- Flexibility – can the financing be increased or decreased as needed?
- Balance sheet impact – does the financing appear as debt or not?
According to the Federation of Finnish Enterprises' financing barometer, 67% of entrepreneurs consider working capital adequacy their most important financing concern. Yet only 35% have actively compared different financing forms – the rest rely on the first option offered.
Working Capital Financing Cost Calculation in Practice
Comparing costs between different financing forms requires standardization. The interest rate or percentage alone does not tell the whole truth. Below is a concrete example that helps understand the actual costs.
Example: A company needs EUR 100,000 in working capital for 45 days. Credit facility (6% p.a.): 100,000 x 0.06 x 45/365 = EUR 740 Invoice financing (1.8%): 100,000 x 0.018 = EUR 1,800 Merchant financing (8% p.a.): 100,000 x 0.08 x 45/365 = EUR 986 The credit facility is the cheapest in euro terms but requires collateral and a longer application process. With invoice financing, the funds are available within 24 hours without collateral.
Applying for Working Capital Financing
The application process varies significantly depending on the financing form. A traditional bank loan or credit facility requires more extensive documentation, while invoice financing has a considerably lighter process.
Typically required documents:
- Latest financial statements (income statement and balance sheet)
- Current year interim financial statements or income statement
- Cash flow forecast for at least 6 months
- Company's basic details and trade register extract
- For invoice financing: sales invoices and customer information
Most Common Mistakes in Working Capital Financing
In my own business and working with clients, I have identified several recurring mistakes that entrepreneurs make with working capital financing.
Avoid these mistakes:
- Applying for financing too late – apply before the situation becomes critical
- Comparing only one option – request quotes from multiple providers
- Forgetting actual costs – calculate the total cost on an annual basis
- Using financing incorrectly – working capital financing should not be used for investments
- Neglecting cash flow forecasting – without a forecast, you don't know your actual need
"The biggest mistake in working capital financing is assuming you don't need it. Every growing company will sooner or later encounter a situation where cash flow is insufficient to cover the working capital required by growth."
Summary
Working capital financing is a fundamental tool for every SME, ensuring business continuity and enabling growth. Choose a financing form based on your company's needs: a credit facility for seasonal fluctuations, invoice financing for B2B companies with long payment terms, merchant financing for wholesale trade, and a Finnvera guarantee for growth companies.
📌 Summary
Working capital financing options include credit facility (4–8% p.a.), invoice financing (1–3% per invoice), merchant financing (5–12% p.a.), and Finnvera-guaranteed loan (3–6% p.a.). The choice depends on cash flow cyclicality, speed requirements, and collateral situation. Invoice financing is the fastest and most flexible option for B2B companies.
