Physical cash costs retailers less than a third of a credit card transaction to accept, yet millions in liquidity sit idle in back-office safes for days. G4S head of retail Nick Belmont explores how forward-thinking retail groups are reclaiming that capital
For a chief financial officer or group treasurer, cash flow is everything. It makes the difference between a retail business with the agility to scale and one held back by high operating costs. Yet, across high-volume enterprise retail, substantial liquidity remains compromised right under our noses. Trapped cash is often left to languish in secure safes for days before it is banked.
Card payments are becoming more expensive than ever. The total cost to UK retailers of processing card payments reached £1.48bn in 2024, representing an eye-watering 108% increase in card-processing costs since 2019.
Meanwhile, physical currency remains a resilient, highly cost-effective payment choice. Physical cash accounts for 19.2% of all UK retail transactions, with processing costs averaging just £0.02 per transaction (0.15% of sales value), compared to 0.28% for debit cards and 0.52% for credit cards. Customers settle nearly one in five transactions with cash, an asset that costs retailers less than a third of a credit card to accept.
The hidden penalty of the safe
If cash is so cost-effective, why does it feel like such an operational drain?
Faced with widespread bank branch closures and low interest rates, many retail groups have reduced Cash-in-Transit (CIT) collection schedules from daily to weekly or bi-weekly to trim transit invoices. While this may make sense on paper, this operational compromise creates an invisible bottleneck: it traps cash in back-office safes.
When currency sits inside a store safe, it is dead to the bottom line. It cannot pay down revolving credit lines, lower interest costs, or support free cash flow to grow your business.
Across a standard seven-day weekly banking cycle, cash sits idle for an average of four days. For a retail group taking £155,000 a day in physical cash, a four-day safe delay leaves £620,000 in trapped cash permanently locked behind steel doors.
When accounting for physical transport, counting, and bank clearing times – stretching the window to seven days – that trapped cash value surges to over a million.
Moving beyond the smart safe: What’s inside the blueprint?
To release this capital, forward-thinking enterprise retailers are shifting from standalone smart safes to connected cash ecosystems, bridging the gap between back-office physical deposits and digital bank credit.
But how do you implement this across a multi-store estate?
In our upcoming G4S Whitepaper, Capital in Motion: Unlocking Trapped Cash in Retail Safes – launching this November – we provide an actionable blueprint for finance leaders to modernise their cash operations.
Inside the upcoming guide, you will discover:
- The liquidity formula: Calculate your group’s exact volume of trapped cash across multi-store estates
- Compressing the conversion cycle: Point-of-sale optical validation enables instant, same-day bank credit before CIT collection even occurs
- Risk and liability offloading: Transfer physical security risks off your balance sheet the moment cash enters the safe
Stop letting your most cost-effective payment method drag down your working capital.
