Cost of Acceptance: Cards vs. Cash - What’s Really Cheaper for Your Business?

Cash-only business might look like the cheaper option on paper, but once you account for the time, risk, and hidden costs of handling cash, it's rarely the bargain it appears to be.

There's a common misconception that restricting a business to cash-only comes with significant savings, based on the idea that payment equipment costs and processing fees outweigh the extra revenue card payments bring in. That may have been true decades ago, when only a small share of customers reached for a card, but with debit and credit now the default payment method of choice by consumers, the cost of accepting card payments is now lower than the costs associated with accepting cash. If you're considering cash-only or a cash discount to save money, it's worth seeing what cash is actually costing you first.

Calculating your merchant fees for credit and debit cards

When we refer to “merchant fees” we are talking about what it costs your business to accept card payments. Your transaction fees cover part of it, but your merchant statement is where the fuller picture lives, including charges some providers add separately, such as terminal rental fees, chargeback fees, receipt roll costs, point-of-sale integration costs, and more. Your true cost of acceptance is the full total, including transaction fees, set-up fees, hardware, account fees, stationery, chargebacks, international card fees, and more.

Calculating the cost of accepting cash

Card and cash processing costs start out broadly comparable on small, low-value transactions. But as volumes grow, cards become the labour-saving choice: fees are handled automatically, while cash requires counting, reconciling, and banking at every step. Card fees are percentage-based and scale with transaction value, cash carries a flat operational cost per transaction, which is what makes it increasingly expensive as sales volume (not transaction size) increases.Beyond direct bank charges, the primary drawback of cash is the hidden administrative overhead. In evidence submitted to Parliament, the Federation of Small Businesses (FSB) highlighted that "one significant challenge is the labour cost associated with handling cash. Businesses need to allocate staff to count, sort, and reconcile cash transactions, which can be time-consuming and labour-intensive. This process not only increases payroll expenses but also diverts staff time from tasks that contribute to business growth." 

The problem with cash acceptance is that it includes a number of expenses that aren’t immediately visible:

• Handling cash, including opening and closing cash drawers, managing change requests, arranging cash-in-transit collections, and managing the risk of on-site theft and scams — a greater concern when cash is your only payment method.

• Counting and banking cash, including reconciling drawers, making bank deposits, paying associated banking fees, and managing the costs of cash-in-transit services.

• Lost sales and slower service, which can result from longer checkout times, affecting both customer patience and your ability to process a higher volume of transactions.

While the issue of lost income is serious, the reality of lost time is even more concerning for UK merchants. Research from the Post Office reveals that small business owners lose nearly 3.5 hours every week, totalling over 182 hours a year, simply counting physical cash, before spending on average another 30 minutes travelling to deposit takings at the bank. That daily admin leads to missed business opportunities with 13% of owners forced to close their doors early or over busy trading periods to work around bank branch closing times, while 70% delay banking their earnings altogether, shifting unnecessary safety and theft risk to the merchant. On top of these factors is the added cost (and risk) of counterfeit currency. While there are a number of ways you can safeguard against card fraud, it's significantly harder to detect 'fake money' in live transactions, particularly when there's no record of the customer's details other than a receipt of purchase.

Can your business afford the cost?

Cash isn't the low-cost option it might look like on paper — but neither is just any card processor. As the chart above shows, cash carries its own stack of hidden costs, from theft risk to the time lost counting drawers and making deposits. Switch to the wrong provider, though, and you can end up paying a similar price in a different form: hidden fees, contract break fees, terminal rental, and rates that climb depending on the card. Either way, you're footing a bill you never see itemised.

The real fix isn't choosing between cash and cards — it's choosing a provider that doesn't recreate cash's problems in a different shape. A provider like Zeller charges low,  predictable rates on every card, with hardware you own outright instead of rent, so there's no stack of add-on fees working against you either way.
