Plain definition
Overtrading occurs when a business expands sales or activity faster than its working capital and funding can support. Growth can increase cash strain because inventory, receivables, staffing, and delivery costs often rise before customer cash arrives.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
A contractor wins a large order that will produce a healthy margin, but must buy materials now and will collect only after completion in 75 days. The owner sees profit in the quote; the cash forecast shows a breach of the minimum balance in week four. The contract needs a deposit, supplier credit, staged billing, or funding before mobilisation.
Why it matters
More sales do not always make a business safer. Overtrading is a timing and capacity problem, not a claim that growth is undesirable.
Practical consequence
Test every major growth plan in a dated cash forecast, including deposits, payroll, stock, tax, and collection dates. Set escalation triggers before the low point is reached.
