In practice, the number of businesses relying on this type of financing is significant. Surveys show that nearly half of UK SMEs face cash-flow challenges. Around 45 percent of firms seeking external finance say they do so specifically for working capital. Late payments from customers make the picture even more difficult, with almost two thirds of SMEs reporting delays as a major issue. As a result, even profitable companies find themselves reaching for short-term credit to stay liquid.
Short-term finance solves an immediate problem, but it comes at a cost that is often higher than many businesses realise.
The true cost of short-term borrowing
For a business using an overdraft to pay a large expense like rent, the cost escalates quickly. A company paying £10,000 in rent while sitting in overdraft for a month could easily pay more than £100 in interest for that single month alone. Over a year, this becomes more than £1,400 in interest before even accounting for the rent itself.
What begins as a temporary solution can easily turn into a recurring debt cycle. Once a business starts relying on short-term borrowing each month, interest charges begin to erode margins, restrict budgets and reduce the flexibility needed to invest in growth.
The impact on SME growth and stability
Research consistently shows that businesses with healthy cash flow are significantly more likely to grow. When cash is readily available, companies can secure better supplier terms, react quickly to opportunities and withstand unexpected shocks without resorting to high-cost borrowing. Managing large outgoing expenses efficiently is therefore a key driver of long-term stability.
Among those large expenses, rent is one of the most important.
Why rent makes the cash-flow challenge worse
Using credit for rent dramatically increases its real cost. Instead of paying only the contracted rental amount, the business also pays the interest associated with borrowing. This makes an already large expense even more burdensome and increases financial pressure every month. Because rent is predictable, recurring and substantial, relying on credit to cover it quickly becomes one of the least efficient ways to manage cash flow.
Why businesses are exploring alternatives
A growing number of companies now prefer predictable, fixed-fee payment methods over interest-based borrowing. Fixed fees make costs easier to plan for, protect margins, and avoid the risk of a temporary cash-flow issue turning into a recurring debt problem. Another advantage is tax efficiency. When a business pays a simple processing fee instead of using credit, that fee is typically tax-deductible. The effective cost becomes lower than the headline percentage.
Card payments also provide an added benefit that borrowing does not: rewards. Many businesses use corporate cards to earn points on travel, accommodation or operational expenses. If a major outgoing like rent can generate those rewards, it creates additional value.
A more efficient way to pay rent
When rent is one of your largest monthly expenses, reducing the cost of paying it and avoiding reliance on high-interest credit is not just a financial optimization. It is a strategic decision that improves liquidity, strengthens cash flow and creates long-term resilience.
