Overtrading occurs when a company grows revenue faster than its working capital can support. The company is profitable on paper but runs out of cash because it must pay suppliers and staff before collecting payment from customers. Revenue grows, the order book looks healthy, but the bank account is empty. Overtrading is insolvency caused by success, not failure.

How does overtrading lead to insolvency?

The cycle: company wins a large contract (or grows sales rapidly), must buy materials and pay staff to fulfil orders, payment from customers arrives 30 to 90 days later, but next month new orders require more materials and staff now. Each month the gap between cash out and cash in grows wider. Eventually the company cannot pay suppliers or HMRC and enters insolvency, despite having a full order book and profitable contracts.

What are the warning signs of overtrading?

Key indicators: revenue growing faster than 30% per year without matching equity injection, creditor days lengthening (paying suppliers later and later), debtor days stable or rising (customers not paying faster), stock levels rising (buying more than selling), overdraft permanently at limit, requesting extended terms from suppliers, HMRC arrears building up, and directors taking no salary or dividends (all cash goes to operations).

Which types of companies are most at risk of overtrading?

High-risk sectors: construction (large contracts, payment milestones delayed, materials upfront), recruitment (paying temps weekly, collecting from clients monthly), manufacturing (raw materials upfront, 60-day customer terms), and any business that wins a contract significantly larger than its normal order size. Fast-growing startups funded by revenue rather than equity are particularly vulnerable.

How do I protect myself from an overtrading customer?

Key protections: check their balance sheet (is working capital positive and growing with revenue?), ask for shorter payment terms or upfront deposits if they are growing fast, monitor creditor days in their accounts (are they stretching suppliers?), watch for HMRC arrears (a common sign), and limit your credit exposure to what you can afford to lose. A company that is growing 50% year-on-year with flat working capital is a time bomb.

Can overtrading be fixed?

Yes, if caught early. Solutions: equity injection (new capital to fund the growth), invoice factoring (converting receivables to immediate cash), slower growth (turning down work until cash catches up), renegotiating customer terms (shorter payment cycles), and renegotiating supplier terms (longer to pay). The key is that the directors recognise the problem before cash runs out completely. Many do not.

Overtrading: When Growth Kills a Company

A growing order book, rising revenue, profitable contracts. And then insolvency. Overtrading destroys companies that appear to be succeeding. The books show profit; the bank account shows zero.

How overtrading works

The overtrading cycle:

Company wins work (new contract, sales growth, big order).
Must spend to deliver (materials, subcontractors, staff, equipment). Cash goes out immediately.
Customer pays later (30, 60, or 90 days after invoice). Cash comes in slowly.
Gap widens each month because next month brings more orders needing more spend.
Cash runs out before revenue catches up. Suppliers go unpaid. HMRC debt builds. Insolvency.

The paradox: the P&L shows profit on every job. The company is winning. Revenue is up. Margins are healthy. But the balance sheet is bleeding cash. Profit does not equal cash. Overtrading is the gap between the two.

Warning signs in the accounts

Revenue growth outpacing working capital. Revenue up 40% but net current assets flat (or negative). The company is growing faster than its capital base can support. Every new sale consumes more cash than the business has.

Creditor days increasing. The company is paying suppliers later (30 days becomes 45, then 60). They are using supplier credit as a free overdraft. When suppliers refuse further credit, the house of cards collapses.

Overdraft at maximum. Permanently at the overdraft limit (or repeatedly requesting increases). The working capital shortfall is being funded by the bank, not by the business. One refused overdraft extension triggers crisis.

HMRC shown as a major creditor. Companies that are overtrading often delay VAT and PAYE payments (because HMRC does not stop supplying goods). If "other creditors" or "taxation" is growing rapidly in the accounts, this is a red flag. HMRC eventually issues winding-up petitions.

High-risk sectors

Construction

Large contracts with milestone payments. Materials and subcontractors must be paid before certifications are issued. A contractor winning a £5M job with £500K working capital must bridge £4.5M of cash flow across the project lifecycle. One delayed payment from the main contractor triggers a chain reaction.

Recruitment

Temps and contractors paid weekly. Clients invoiced monthly (or longer). A recruitment agency placing 100 temps at £500/week pays out £50K/week but collects £200K/month. The timing gap means £50K to £100K of permanent working capital is needed just to stand still.

Manufacturing

Raw materials purchased upfront. Production takes weeks. Finished goods shipped. Customer pays 60 days after invoice. A manufacturer growing 30% needs 30% more working capital just to fund the longer pipeline. Without equity injection, the bank fills the gap (until it does not).

Fast-growing startups

Revenue-funded startups (no VC, growing on profits) are classic overtrading candidates. They are succeeding: customers love them, sales grow 50% or more per year. But each sale costs cash before it returns cash. Growth becomes a treadmill you cannot step off without falling.
