Financing your first big contract without overtrading

Overtrading is what happens when a business grows faster than its cash can support. It is one of the more painful ways to fail, because it happens to businesses that are winning — and the owners often do not see it coming, because every commercial signal looks positive.

A contract two or three times larger than anything you have delivered is the classic trigger.

Why a big win creates risk

The costs of a large contract land before the revenue does. You buy materials, take on staff, perhaps lease equipment — all upfront. The invoice goes out on completion or on milestones, and then sits on your customer's 60-day terms.

The bigger the contract, the bigger and longer that hole. Meanwhile your existing business still needs funding, and it is usually the existing business that starves.

Work out the true cash requirement first

Before accepting, map the actual cash timeline rather than the profit.

1. List every cost and the week it must be paid.
2. List every expected receipt and the realistic week it will arrive — using your customer's actual payment behaviour, not their stated terms.
3. Plot the running balance week by week.
4. Find the deepest negative point. That is what you need to fund.

Negotiate before you finance

The cheapest funding is a better contract structure. Before taking on cost, try to secure:

• A deposit or mobilisation payment upfront.
• Milestone billing rather than a single invoice on completion.
• Shorter payment terms in exchange for a small discount.
• Extended supplier terms that align with your customer's payment schedule.

Buyers who genuinely want delivery are often more flexible on payment timing than on price. It costs nothing to ask.

Then match financing to the shape of the gap

• Supplier and material costs upfront — trade financing, which pays suppliers directly and clears when the trade settles.
• Completed work awaiting payment — invoice financing, releasing up to 90% of the invoice immediately.
• General delivery costs like labour and overheads — a working capital loan with fixed repayments.
• A short, defined gap with a confirmed incoming payment — a bridging loan.

How trade financing funds supplier payments

Protect the core business

The most common overtrading failure is not the new contract collapsing. It is the new contract consuming all available cash, so the reliable existing business cannot buy stock or pay staff. Ring-fence working capital for business as usual before committing it to the new job.

Warning signs during delivery

• You are delaying supplier payments on other accounts to fund this one.
• The customer is slipping on milestone sign-off, pushing your invoice dates back.
• Scope is expanding without a corresponding variation to price or payment.
• You are using the contract deposit to cover unrelated operating costs.

Any of these warrants an immediate re-forecast. Problems caught in week four are manageable; the same problems in week twelve usually are not.

It is acceptable to say no

A contract you cannot fund is not an opportunity — it is a risk with good marketing. If the peak requirement exceeds what you can raise and the buyer will not improve terms, declining is a legitimate commercial decision. Businesses rarely fail from the contract they turned down.
