When a business grows, the problem is usually not a lack of sales, but a lack of liquidity. You get paid by large customers in 60, 90, or 120 days, while payroll, suppliers, taxes, and purchases can’t wait. That’s where a well-designed working capital financing structure makes the difference between growing with peace of mind and living with constant cash flow stress.
In this article, we’ll take a practical look at how to combine four key tools—promissory note discounting, invoice advances, factoring, and confirming— to build a diversified, flexible financing structure that’s less reliant on traditional banks.
Working capital financing is everything you use to fund day-to-day business operations: purchases of inventory, raw materials, salaries, taxes, fixed expenses, etc., until you collect payment from your customers.
In B2B companies that sell to large corporations or government agencies, the mismatch between collection terms (60/90/120 days) and payment terms is the main source of cash flow strain. This isn’t a one-off problem—it’s structural. That’s why the solution isn’t just to “hold on” or ask the bank for more lines of credit, but to design a stable and diversified financing structure based on your receivables (invoices and promissory notes).
Entrusting all your working capital financing to a single institution or a single instrument (for example, only a bank credit line or only a discount line) carries several risks:
– CIRBE limit: Your bank lines of credit are counted toward your CIRBE limit, and once you reach certain exposure levels, it becomes harder to grow or renegotiate terms.
– Lack of flexibility: The bank may revise limits, collateral requirements, or terms just when you need liquidity the most.
– Risk concentration: If an institution decides to reduce its exposure to you, your financing structure is immediately affected.
– Products ill-suited to your reality: Standard credit facilities and lines often do not align well with the type of debtor, seasonality, or your operational needs.
The alternative is to diversify: combine different instruments (promissory notes, invoices, factoring, confirming) and different providers, including independent finance companies specializing in working capital that do not use CIRBE and apply risk criteria tailored to the debtor.
What it is
Short-term financing that allows you to receive payment in advance for promissory notes issued by your customers (typically large companies or corporations). You submit the promissory note and receive the funds, minus the agreed-upon interest and fees.
When it’s most suitable
– When your customer pays you via promissory notes due in 60/90/120 days.
– When you have large, creditworthy customers and want to convert those notes into immediate liquidity.
– When you want to avoid cash flow constraints to pay payroll, suppliers, and taxes.
Key Benefits
– You convert credit sales into cash receipts.
– It’s a very flexible solution for recurring working capital needs.
– With specialized financial institutions like Workcapital, many transactions do not require the same guarantees as traditional banks and do not appear on your CIRBE credit report.
With and without recourse
– With recourse: if the payer fails to pay by the due date, the ultimate risk falls on your company. These arrangements typically offer more competitive pricing.
– Without recourse: the financier assumes the risk of nonpayment under certain conditions; this can help you improve balance sheet ratios by treating part of the financing as “off-balance-sheet” and reducing bank concentration.
What it is
Financing based on invoices issued and accepted by your customers, without the need for a promissory note. You submit the invoice and receive a full or partial advance.
When it’s most suitable
– When you invoice large companies or government agencies that pay on long-term terms.
– When your customers use bank transfers or payment receipts instead of promissory notes.
– When you don’t want to increase your bank credit lines but do need immediate liquidity.
Key Benefits
– You don’t need to switch banks or overhaul your entire operations.
– The assessment focuses on the debtor’s (your client’s) creditworthiness, not just your financial statements.
– A 100% digital process with minimal documentation if you work with a specialist like Workcapital.
What It Is
Factoring combines invoice financing and collection management. You assign your trade receivables from specific customers to the financier, who advances you the amount and manages the collections.
When It’s Most Appropriate
– Companies with a recurring volume of invoicing to specific customers (top customers).
– Growing small and medium-sized businesses that want to professionalize their accounts receivable and obtain ongoing liquidity.
– Companies with a high concentration of risk in a few debtors.
With and without recourse
– With recourse: the risk of default remains yours. These solutions are typically competitively priced and operationally flexible.
– Non-recourse: the lender assumes the risk of default (subject to limits and conditions). This helps you:
· Reduce concentration risk with large customers.
· Improve your financial ratios by treating part of that financing as off-balance-sheet.
· Reduce traditional bank exposure and pressure on the CIRBE.
Key Benefits
– Recurring liquidity from your accounts receivable portfolio.
– Professional collections management, reducing internal workload.
– Ability to set limits per debtor and establish credit policies consistent with your growth plan.
What It Is
A tool that allows you to finance payments to your suppliers. The financier pays your suppliers on the agreed-upon date (or even earlier, if the supplier chooses to receive payment in advance), and you maintain your usual payment terms.
When it’s most suitable
– Companies with a significant volume of purchases from key suppliers.
– Situations where you want to improve your negotiating power with suppliers (payment terms, prices, early-payment discounts).
– When you want to ensure there are no issues with payroll or supplier payments, without straining your bank lines of credit.
Key Benefits
– Strengthens relationships with suppliers: they can get paid sooner if they choose.
– Allows you to standardize payment processes and gain control.
– Diversifies your sources of working capital financing, since you’re financing “payments” and not just “receipts.”
The key isn’t to have every product, but to design a structure that aligns with your business model, customer base, and working capital volume. Here are some practical guidelines:
Typical scenario
– 3–10 large customers who account for the majority of your revenue.
– Long payment terms (60/90/120 days).
– Monthly cash flow strain to cover payroll and taxes.
Recommended combination
– Discounting promissory notes (when your customer pays you with promissory notes).
– Invoice advances (for clients who pay by bank transfer or check).
– A comprehensive working capital line that allows you to use one or the other depending on the type of payment instrument and the timing.
Objective
– To convert a significant portion of your credit sales into immediate liquidity.
– Avoid relying solely on your bank credit line and reduce pressure on your CIRBE credit rating.
– Gain the capacity to accept a higher volume of work from these clients without compromising your cash flow.
Typical Situation
– You regularly invoice several medium- and large-sized clients.
– You’re experiencing double-digit growth, and your working capital needs are increasing faster than your bank lines of credit.
– You’re starting to notice that managing collections and monitoring customer risk are becoming more complicated.
Recommended Combination
– Recourse factoring for certain customers and invoice advance lines.
– Discounting promissory notes for specific transactions or clients who use this payment method.
– Specific advice on working capital financing to define limits per top debtor and credit policies.
Objective
– Align your financing structure with your growth: ensure your credit lines keep pace with rising sales.
– Professionalize customer credit management: fewer collection issues and greater ability to forecast cash flow.
– Begin diversifying financial providers beyond traditional banks.
Typical Situation
– A significant portion of your revenue comes from 3–5 large accounts.
– You get paid well, but late, and a problem with one of these customers would have a direct impact on your cash flow.
– Your banks are already heavily exposed to these debtors through your discount lines.
Recommended Combination
– Non-recourse factoring for your top clients, up to certain limits.
– Supplement this with invoice advances or recourse discounting of promissory notes for the rest of the portfolio.
– Confirming with suppliers to increase margins on payments.
Objective
– Reduce risk concentration on the balance sheet and improve financial ratios.
– Free up credit lines (CIRBE) and diversify financial providers.
– Protect your cash flow against potential delays or collection issues.
Typical Situation
– High volume of purchases and sales.
– Interest in optimizing supply chain financing costs and building supplier loyalty.
– Need for flexibility, reporting, and customized solutions.
Recommended Combination
– Well-designed supplier factoring programs, combined with factoring lines (with or without recourse) for specific customers.
– Custom solutions to finance specific projects or campaigns (for example, supplemental working capital loans).
Objective
– To optimize the overall cost of supply chain financing.
– Improve negotiating power with suppliers by providing them with access to liquidity.
– Gain flexibility and diversify beyond traditional banking.
Let’s imagine an industrial SME with annual revenue of 8 million euros, primarily from six major accounts that pay on a 90-day terms.
Company objectives:
– Ensure liquidity to sustain projected annual growth of 15%.
– Reduce monthly cash flow pressures.
– Avoid relying solely on traditional banks for financing.
Possible structure:
Global working capital line with a specialized partner (e.g., Workcapital)
– A comprehensive credit line that combines:
· Discounting of promissory notes (for customers who use this method).
· Invoice advances (for those who pay by bank transfer).
– Flexible use depending on the composition of monthly sales.
Non-recourse factoring for 2 top clients
– To reduce risk concentration and improve financial ratios.
– Specific limits per debtor, reviewed periodically.
Supplier Confirming
– Program for key raw material suppliers.
– Objective: to negotiate better purchasing terms and ensure that payments are processed without issues.
Traditional bank support policy
– More tactical use, for very specific peaks in demand.
– Less structural dependence on this line of credit, which reduces pressure on CIRBE.
Result:
– The company converts a significant portion of its credit sales into immediate liquidity.
– Gains room to maneuver with banks and customers.
– Financing is aligned with its business model and growth rate.
Focusing only on the interest rate
The actual cost includes fees, underwriting costs, hidden terms, and, above all, the opportunity cost of not having the liquidity to take advantage of business opportunities.
Relying on a single lender
A unilateral decision can leave you unable to react. Diversifying suppliers and products reduces that risk.
Failing to Segment by Debtor Type
Financing invoices from a highly creditworthy top-tier customer is not the same as financing those from a new customer with a shorter credit history. Designing credit limits and products based on debtor profile is key.
Failing to calculate the impact on CIRBE and the balance sheet
Certain financing methods (such as non-recourse factoring) can improve ratios and reduce traditional bank exposure. Ignoring this effect means missing out on a very important lever.
Viewing working capital financing as tactical rather than strategic
Many companies only react once cash flow pressures have already arisen. Proactively designing a financing structure allows you to grow with fewer surprises.
For many SME managers, CFOs, and treasury managers, the challenge isn’t understanding each product individually, but rather how to optimally combine them based on their specific circumstances: customer type, volume, seasonality, relationship with banks, and growth objectives.
That’s where a partner specializing in working capital financing adds value:
– They analyze your customer portfolio (debtors) and your collection/payment terms.
– Designs a structure that combines promissory note discounting, invoice advances, factoring (with or without recourse), and confirming.
– It sets limits per top debtor and usage policies that balance cost, flexibility, and security.
– Offers digital processes, agile decision-making, and solutions that do not appear on the CIRBE credit report, helping you reduce your reliance on traditional banks.
