Capital Equipment: Buy, Lease, or Finance? The Decision That Costs SMBs Thousands When Made Wrong

The Equipment Decision Most Owners Get Wrong#

The conversation typically goes: "We need a new van. The old one is costing £800/month in repairs." "How much is a new one?" "£28,000." "Can we afford it?" "We have £31,000 in the bank." Decision: buy it outright. What wasn't considered: payroll due next Friday (£12,400), supplier payments due end of month (£8,200), and a slow January coming. After buying the van outright, the bank balance is £3,000 heading into a slow month. The business is asset-rich, cash-poor, and one delayed invoice away from a crisis. A £28,000 van on finance at £490/month would have cost £2,940 more over five years but preserved £25,000 of working capital.

Outright Purchase: When It Makes Sense#

Buy outright when: you have strong cash reserves well above your three-month operating cost buffer, the equipment has a long life with low maintenance cost, you want to avoid interest cost and have the cash to avoid it without stress, or you're buying at a significant discount (auction, distressed seller) that more than covers the opportunity cost of the cash. The key test: after buying this outright, do you still have three months of operating cash plus a safety margin? If yes, outright purchase is often the right choice.

Leasing: The Cash Flow Preserving Option#

Leasing keeps the equipment off your balance sheet (depending on lease type), preserves working capital, and allows you to upgrade at end of term. The total cost is higher than outright purchase — you're paying for the financing. But for equipment that depreciates quickly (technology, vehicles, some food equipment), leasing can be economically rational even ignoring cash flow benefits. The test: will the equipment generate enough incremental revenue to cover the lease cost plus a margin? If the £450/month oven generates £900/month in incremental catering sales, it pays for itself plus profit from day one.

Finance and Hire Purchase: The Middle Ground#

Hire purchase (HP) or equipment finance splits the cost over time with interest, and you own the asset at the end. Better than leasing if you want ownership; better than outright purchase if you need to preserve cash. The decision variable is the interest rate. At 5–7%, the interest cost on a £20,000 machine over 3 years is £1,500–£2,100 — worth paying if the cash preserved generates more than that in your business. At 15%+, the interest cost is significant and you should reconsider. Always model the total cost of finance, not just the monthly payment.

Modelling the Decision in AskBiz#

AskBiz's capital planning tool lets you enter three scenarios: outright purchase (show the cash flow impact on your 13-week forecast), lease (show the monthly cash flow impact for the lease term), finance/HP (show the monthly payment and total interest cost). Each scenario updates your projected cash position so you can see the real-world impact on your liquidity. For the £28,000 van example: outright purchase scenario shows a £3,000 cash position entering January (dangerous). Finance at £490/month shows £28,000 preserved with a £490/month outflow (manageable). The decision becomes obvious when you can see the numbers, not when you're guessing.

• A £25,000 commercial oven bought outright drains your working capital and may have been available on a £450/month lease.
• A £15,000 CNC machine financed at 8% over 3 years costs £18,720 total but preserves £15,000 of cash that generates more than £3,720 in the business over three years.
• Capital expenditure decisions are the ones that can cripple a healthy business if made without a cash flow model.
