How to finance your operating needs: The complete guide

Operating Cash Flow (OCF), also known as Working Capital Requirement (WCR), is one of the major financial challenges facing French companies. According to our research, nearly 90% of companies generating over €2 million in sales face recurring WCR problems. In this article, we explore the different financing solutions available to optimize your cash flow.
What is operating cash flow?
BFE corresponds to the funds required to cover your company's operating cycle. It is calculated according to the following formula:
BFE = Inventories + Trade receivables - Trade payables
A positive EBT indicates that your company needs to finance the gap between sales receipts and the payment of current expenses. This situation, while normal for most companies, can create significant cash flow pressures.
BFE components
- Inventories: value of goods awaiting sale - Trade receivables: amounts due from customers (payment terms)
- Trade payables: amounts due to suppliers
Why finance your BFE?
BFE financing is crucial to maintaining your company's financial equilibrium. On the one hand, it ensures business continuity by guaranteeing payment of salaries and fixed charges. On the other, it enables you to seize growth opportunities without compromising your financial stability.
Companies that control their BFE can :
- Invest in marketing and customer acquisition- Recruit key talent at the right time- Build strategic inventories- Negotiate better terms with suppliers

4. Traditional banking solutions
Banks offer several products to finance BFE, each with its own specific features:
The authorized overdraft or overdraft current account is a flexible, one-off solution, but its high cost over time and its dependence on the banker 's approval make it less attractive for regular use.
Short-term credit offers short- to medium-term financing (3 to 12 months), but often involves substantial collateral and a lengthy, complex process that can hamper entrepreneurial responsiveness. For a more modern approach, discover the best short-term financing solutions available on the market.
Conventional bank loans often require fixed asset guarantees and can impact your available working capital.
5. Participative financing
Crowdfunding can be an interesting alternative for some companies, particularly when it comes to financing specific projects or product launches. This approach makes it possible to mobilize a community while validating market interest.

Optimizing BFE management
Preventive strategies
Proactive BFE management begins with optimization of the three main components. Negotiating payment terms enables us to reduce customer lead times while extending supplier lead times, thus creating a natural leverage effect on cash flow.
Improving inventory management is another major lever:- Optimize rotation to reduce downtime- Implement demand forecasting tools- Negotiate flexible supply conditions.
Speeding up cash receipts means setting up efficient reminder systems and automating invoicing processes. Last but not least, diversifying sources of financing means combining several solutions to optimize the overall cost of capital.
Steering tools
Effective cash flow management requires the right tools. The cash flow dashboard provides real-time monitoring of cash flows, while the BFE forecast enables you to anticipate future needs. Performance indicators such as DSO (Days Sales Outstanding), DPO (Days Payable Outstanding) and inventory turnover provide a clear view of operational efficiency.
