Strategies for effective and sustainable SME cash flow optimization

Managing the cash flow of an SME is a daily challenge. As the founder of Evevest, with solid institutional experience, I share with you concrete and proven strategies. These are the methods used by the largest pension funds and family offices to secure and grow their cash reserves. You will discover how to optimize your SME's cash flow, combining prudence and performance.

Why cash flow optimization for SMEs is essential

Cash flow is the lifeblood of any business. Healthy cash flow ensures sustainability, investment capacity, and the ability to manage unforeseen events. Yet, many business leaders underestimate its importance or don't know how to manage it effectively.

Optimizing cash flow for SMEs is, above all:

• To ensure liquidity to meet current expenses.

• Maximize the return on surplus cash.

• Reduce the financial costs associated with overdrafts or credit.

• Preparing for the future by securing resources.

  
  

For example, an SME that anticipates its cash flow needs avoids unnecessary bank charges and can negotiate better terms with its suppliers.

Concrete levers to optimize your SME's cash flow

Here are the main strategies I have observed and implemented in various contexts, always with an insider's perspective.

First step: segment the cash into pockets

The methodological error lies in seeking "the right investment" before mapping one's cash flows. An institutional treasurer never reasons this way. They first segment their cash into distinct categories, each corresponding to a specific liquidity and time constraint.

1. Operating funds. Everyday money : salaries, suppliers, VAT, corporate tax. Total availability, no restrictions. We're not looking for returns here, we're looking for absolute security and immediate liquidity.

2. Emergency fund . Funds that can be accessed within three to six months to absorb an unforeseen expense or finance a known deadline. Investment is possible, but only in liquid assets with very low volatility.

3. Stable reserve . The true surplus , with no identified use for it for two or three years. It is this reserve, and this reserve alone, that can aim for a higher return by accepting a longer maturity.

This segmentation determines everything else. The portion that can actually be invested depends on your operational visibility, your sector, and your business cycle. In practice, we observe that many companies can tie up a significant portion of their cash without ever impacting their ability to operate, simply because this portion has remained unchanged for years.

Second step: choosing the right envelope

Before the product, there's the packaging. It's this that determines taxation, and therefore net return. For a company subject to corporate income tax, two containers structure the majority of investment decisions.

The ordinary securities account (CTO)

The flexibility of the investment package lies in its broad range of assets (money market funds, bonds, target-date funds, ETFs, SCPIs, structured products) and its constant liquidity. However, this comes at a price: income and capital gains are subject to corporate income tax (25% on profits exceeding €42,500), regardless of any withdrawals. Capital is thus subject to recurring tax friction.

When to use it: For an emergency fund and any cash reserves whose use date remains uncertain. The tool for managers who prioritize availability.

The capitalisation contract held by a company subject to corporate income tax

The investment term is capped. Contrary to popular belief, it does not benefit from a total deferral of taxation: it is taxed annually, but on a flat-rate basis and not on actual performance. This base rate is obtained by applying to the nominal value a rate equal to 105% of the average government bond yield (TME) observed at the time of subscription and fixed for the entire life of the contract.

The consequence is decisive: if actual performance exceeds this base, the difference escapes corporate income tax as long as there is no redemption. Unrealized capital gains are not taxed, and the capital operates with reduced friction. Added to this are the absence of social security contributions and the exclusion from the tax base of the 20% tax on asset-holding companies (2026 Finance Law), making it a relevant tool for structuring holding company cash flow.

Note: Euro-denominated funds are only accessible to asset management companies and non-active holding companies. Unit-linked funds remain open to all companies subject to corporate income tax.

When to use it. For stable capital, over the medium to long term, particularly within a holding company. The tool for managers who want to let their capital grow over time.

Third step: Optimize cash investments

Excess cash should not remain idle. It must be put to work without taking excessive risks.

This is where institutional experience becomes truly meaningful. Large investors favor secure, liquid investments that offer a higher return than current accounts.

I invite you to discover how to invest your SME's cash reserves to benefit from solutions tailored to your profile and needs.

What is the best investment for a company's cash reserves?

This question comes up often. The answer depends on several criteria:

• Investment duration : short-term available cash or tied-up funds.

• The acceptable level of risk : safety is the priority.

• The necessary liquidity : the ability to quickly recover funds.

  
  

The most common solutions are:

• Fixed-term accounts : secure, with a moderate return, but not very liquid.

• Money market funds : highly liquid, low risk, variable return.

• Short-term government bonds : safe, but often with a low return.

• Structured investments : suitable for larger cash reserves, combining security and performance.

  
  

In all cases, it is crucial to diversify investments to limit risks and optimize returns.
