Cash Flow: How It Works, Costs, and Alternatives in 2026

What is a cash flow statement?

A line of credit is a revolving credit facility: the bank sets a credit limit that the company can draw upon, repay, and then draw upon again, without having to submit a new application each time. It belongs to the broader category of working capital loans, but differs from it in its flexibility: there is no fixed repayment schedule, and there are no specific restrictions on how the drawn amount may be used. From an accounting perspective, it appears on the liability side of the balance sheet under current bank loans (account 519), within short-term financial liabilities, which clearly distinguishes it from a medium- or long-term loan.

How does a cash flow work on a day-to-day basis?

Authorization is generally granted for one year and is automatically renewed following a review of the application. The company may draw on all or part of the credit line without having to provide documentation for each transaction and repays the amount as soon as cash inflows allow. Interest (agios) is calculated only on the amount actually used and the number of days it is used, making it a significantly less expensive option than a traditional loan if usage remains occasional.

ℹ️ An e-commerce business that must pay its suppliers 60 days before the year-end sales draws €80,000 from its line of credit in October, gradually repays the amount as payments come in during November and December, and pays interest only on the days the credit is actually used.

The Components of the Cost of a Cash Flow Line

The advertised cost (the interest rate) represents only part of the actual bill. Several charges add up, and the bank rarely breaks them down on its own:

• Interest rate: indexed to the 3-month Euribor, plus a margin of 1.5 to 3.5 points depending on the risk profile.
• The Highest Balance Fee (CPFD): 0.05% to 0.50%, applied to the highest balance reached each quarter, even if that peak lasted only one day.
• Transaction fee: 0.025% to 0.05% of the total account debits, regardless of whether the line itself is used.
• The non-utilization fee: 0.10% to 0.25% of the undrawn credit line, charged by some banks to recoup the costs associated with the commitment they have made.
• Application fees: charged upon enrollment, and then often charged again at each annual renewal.

A one-time cash advance may seem easier to negotiate, but it does not cover a recurring need—this is where the revolving nature of the line of credit really comes into its own.

Cash Line, Authorized Overdraft, or Short-Term Loan: Which Should You Choose?

The three tools look similar on paper, but are based on different principles. An authorized overdraft is activated immediately, without any paperwork, but its limit remains low and the cost rises quickly after just a few days of use. A line of credit, on the other hand, is formalized through an agreement, offers a higher limit, and is designed for recurring use. The short-term loan is radically different: a fixed amount released in a single lump sum, repaid according to a defined schedule, tailored to an identified, one-time need—such as a one-off investment. The real challenge, therefore, is not to find the cheapest solution on paper, but the one that matches the nature of the need: one-time or recurring?

ℹ️ A regional distributor whose working capital increases each year as revenue grows uses its line of credit as a permanent buffer, when it would be better off utilizing one of the traditional short-term financing solutions for a one-time investment in a new warehouse.

A properly sized cash flow never fills up completely: it absorbs unforeseen events; it does not finance structural growth.

Cash Flow and Working Capital Management

The cash flow statement can only be fully understood in light of the company’s working capital requirement (WCR). The WCR measures the time lag between accounts receivable, inventory, and accounts payable: the longer accounts receivable take to collect, the wider the cash flow gaps become, and the more the need for short-term financing increases. A company whose customers pay on a 60-day terms while it pays its own suppliers on a 30-day terms faces structural cash flow needs, regardless of its profitability. A single receivable that remains unpaid at its due date is sometimes enough to destabilize the company’s cash flow for several weeks.

Working capital (or “fond de roulement,” depending on the spelling used) measures the safety margin provided by equity and medium-term debt relative to fixed assets. When this working capital is no longer sufficient to cover working capital requirements (WCR), the company must find additional liquidity elsewhere: through a bank overdraft, a line of credit, or by converting receivables into cash via discounting. The banker then reviews the current account balance, typical payment terms, and the effectiveness of customer collections to assess the strength of the company’s financial structure.

A monthly cash flow forecast covering a 12-month period makes it possible to anticipate these cash flow difficulties before they become critical. It distinguishes between operating and financing cash flows and shows the actual net cash position at each due date, rather than a snapshot of the bank balance, which can mask a latent cash need.

We launched Karmen Loan to provide working capital financing without the red tape of traditional banking

Negotiating a line of credit with a bank often takes several weeks—including application review, credit committee approval, and signing the agreement—with no guarantee that the approved credit limit will match the actual need. To address this delay, we launched Karmen Loan: from €30,000 to €5 million, for terms ranging from 1 to 24 months, with a quick response and no assignment of debt. For businesses whose financing needs are directly linked to inventory, our inventory pledge option allows them to obtain a loan up to the value of their inventory, as appraised by a recognized third party (Auxiga), without the owner having to part with possession of the inventory.

How to Obtain a Line of Credit: What Documents to Prepare

The amount granted depends directly on the quality of the application submitted. A bank seeks first and foremost to assess the frequency and actual extent of the cash flow gap, not just the reported revenue:

• Balance sheets and income statements for the last two fiscal years.
• 12-month cash flow forecast, highlighting seasonality or customer payment terms.
• Justification for the need: changes in working capital requirements, longer customer payment terms, and the seasonal nature of the business.
• Status of credit lines already in place with other institutions.
• Bank account information and Kbis certificate issued within the last three months.

This application allows the bank to assess your ability to fund your operating needs over the long term, rather than just at a single point in time. The more detailed the application, the closer the negotiated credit limit will align with your actual needs, without an excessive safety margin that would result in costly non-utilization fees.

Working capital remains a useful tool for absorbing the fluctuations of an operating cycle, provided that its actual cost is kept under control and it is not mistaken for a tool to finance growth. For a one-time need or a need that requires faster access to funds, alternatives such as Karmen Loan make it possible to secure working capital without having to wait several weeks for bank negotiations.
