Overtrading
When a business takes on more work than its cash flow can sustain - growing revenue faster than it collects payment. Despite a full order book, the business struggles to pay suppliers, wages, and overheads on time because cash is leaving faster than it arrives.
Overtrading occurs when a business takes on more work than its cash flow can sustain. Sales may be growing and the order book may look healthy, but cash is leaving the business - in wages, supplier payments, and overhead costs - faster than it is being collected from customers. The result is a cash flow crisis despite a full pipeline, a scenario that catches many growing small businesses off guard.
What Causes Overtrading
Overtrading typically develops gradually. A business wins a series of contracts or orders, each requiring upfront expenditure before any customer payment is received. If payment terms are long - 30 to 60 days after invoice is common across construction, office furniture, and promotional merchandise - cash leaves the business faster than it comes in.
Common triggers include:
- Taking on a large contract without securing an upfront deposit or staged payment schedule
- Extending credit to new customers without credit-checking them first
- Growing headcount rapidly, funded from trading cash rather than external finance
- A seasonal spike in demand that isn't matched by flexibility on supplier payment terms
The warning signs are visible before the crisis hits. Suppliers chasing overdue payments, the overdraft being hit before payroll runs, delays in meeting VAT or tax obligations, and difficulty paying sub-contractors on time are all early indicators that cash outflows are outpacing inflows.
Managing the Overtrading Risk
Managing overtrading is primarily a cash flow discipline. The goal is to match the timing of cash outflows to cash inflows as closely as possible. Practical steps include negotiating stage payments or deposits on larger contracts, chasing outstanding invoices proactively before payment becomes overdue, and using credit terms from suppliers to defer outflows where possible.
Some businesses use invoice financing to access cash tied up in unpaid invoices before the customer pays. This can ease short-term pressure but adds cost and should be assessed against the margin impact.
Revenue is not cash
A business with £1 million in annual turnover and 60-day payment terms has - on average - around £164,000 sitting in unpaid invoices at any given time. If most costs fall due in 30 days or less, that timing gap creates a structural cash deficit regardless of how profitable the business looks on paper.
