SME financial management: cash flow and treasury.

Companies do not go bankrupt for lack of profit: they go bankrupt for lack of cash. The cliché contains a truth that too many owners discover too late. You can have a profitable business on paper and run out of money to pay next month's payroll because your customers take 90 days to pay while your suppliers demand 30. Profit is an accounting opinion; cash is a bank fact. And it is the bank fact that decides whether your company survives.

The difference between profit and cash that can sink you

Your income statement says you made €100,000 this year. Your bank account says you have €5,000. How is that possible? Because you invoiced a lot but collected little (customers who owe you). Because you bought stock you have not yet sold. Because you invested in equipment you amortise over 5 years but paid for in cash. Because the VAT on issued invoices is paid to the tax authority even if you have not yet collected from the customer.

Understanding this difference is the first step in financial management. The second is actively managing treasury so the money is in your account when you need it, not in your customers' accounts.

The 13-week cash flow plan

The most useful financial management instrument for an SME is the 13-week treasury plan (one quarter). It is a simple table that projects, week by week, expected receipts, committed payments and the resulting cash balance.

For each week, record the opening balance, expected receipts (invoices to collect with realistic, not optimistic, dates), committed payments (payroll, social security, rent, suppliers, taxes, loans) and the closing balance. If any week ends with a negative balance, you have a problem to resolve before that week arrives: accelerate collections, delay non-critical payments or arrange financing.

Update the plan weekly with real data. In 30 minutes a week you will have more financial control than 90% of Spanish SMEs.

The 6 financial ratios to watch

Liquidity ratio (current assets / current liabilities)

Measures your ability to pay short-term debts with your liquid assets. A ratio above 1.5 is healthy. Below 1 you are in the risk zone.

Days sales outstanding (customers × 365 / sales)

Measures how many days it takes to collect from customers. In Spain, the average is around 75-85 days, but the Late Payment Law sets a maximum of 60 days (30 for the public sector). Every day you reduce DSO frees up cash flow.

Days payable outstanding (suppliers × 365 / purchases)

Measures how many days it takes to pay your suppliers. Ideally, your payment period should be longer than your collection period so cash flow works in your favour.

Gross margin (sales - cost of sales) / sales

Measures the direct profitability of your activity before overheads. A low gross margin signals that prices are too low, costs too high, or both.

EBITDA / sales

Measures your business's ability to generate operating profit before depreciation, interest and taxes. It is the indicator banks and investors look at first.

Leverage ratio (total debt / equity)

Measures your company's leverage. A ratio above 2 indicates a debt level that can be dangerous, especially in a rising interest-rate environment.

Annual budget: your financial GPS

An annual budget is not a prediction: it is a financial plan that establishes the revenues you expect to generate (by business line, by customer, by market), the costs you will incur (fixed and variable), the investments you will make, the financing you need and the expected result.

The budget lets you compare each month actual versus forecast, spot deviations before they get serious, and make informed decisions on expenses and investments.

Profitability by service, product and customer

One of the most important (and most neglected) financial decisions in SMEs is knowing the profitability of every business line, every service and every customer. It is common to discover that 80% of the profit comes from 20% of customers, that some services that look profitable are not when you allocate all costs, and that some customers who invoice a lot are barely profitable because of the resources they consume.

This analysis sometimes produces uncomfortable decisions (dropping a service, parting ways with a customer), but those are the decisions with the biggest impact on overall profitability.

Funding sources for SMEs

The most relevant funding options for Spanish SMEs in 2026 include self-financing (reinvesting profits, the healthiest), bank financing (credit lines, loans, invoice discounting), ICO lines for investment and liquidity, mutual guarantee societies (SGR) that back operations with banks, factoring and confirming to accelerate collections and manage payments, and subsidies such as Kit Digital, Kit Consulting, DigitalICE in Castile and León and Digiempresas in the Canary Islands, bearing in mind that current legislative provisions allow new calls to open as planned.
