Bridging the Gap Between Contract Win and First Payment for a UK Business

Why contract wins create immediate financial pressure

Winning a major contract is the moment a scaling business is working towards. It is also the moment at which cash demands escalate sharply. The company must hire staff or redeploy resources, procure materials or equipment, fulfil onboarding requirements, and begin delivery — all before a single invoice has been issued, let alone paid.

The larger the contract, the larger the gap. A business that wins a contract worth £500k per year, with a three-month ramp and 60-day payment terms, may need to find £150k–£200k in working capital before the first payment arrives. If that is not planned and financed in advance, the contract win can precipitate a cash crisis.

Mobilisation finance and contract-backed facilities

Some commercial lenders offer mobilisation finance — funding specifically for the pre-revenue phase of a new contract. The signed contract itself serves as the primary security, supplemented by the company's general creditworthiness. The facility covers the mobilisation period and transitions to invoice finance once billing has begun.

For companies with a strong track record of delivering similar contracts, the application process can be relatively rapid. For a company entering a new sector or scaling to a significantly larger contract size, the lender will require more evidence that the company can deliver — evidence of management capability, relevant certifications, and supply chain arrangements.

Negotiating payment terms within the contract

Before looking externally for finance, directors should exhaust the possibility of improving payment terms within the contract itself. A milestone-based payment schedule — releasing cash as deliverables are completed rather than at the end of the contract — dramatically reduces the financing requirement. A mobilisation payment from the customer at contract signature covers the initial ramp costs. Advance payments against purchase orders are common in manufacturing and supply contexts.

Customers who are creditworthy, repeat commissioners of services often have standard contract payment terms that can be negotiated on a bilateral basis. The worst outcome is to accept the default terms without asking. The negotiation should happen before signature, not after.

Invoice finance as the contract scales

Once billing has begun under the contract, invoice finance provides the most scalable way to accelerate cash from the receivable. Each invoice is advanced — typically 80–85% of its face value — within 24 to 48 hours of issue, with the balance released when the customer pays. For a contract generating regular invoices, this converts what would otherwise be a 60-day payment cycle into a near-immediate cash receipt.

The facility limit needs to be set at the beginning to accommodate the expected invoice volume at full run rate, not just the first month's billing. Directors should brief the invoice finance provider on the expected growth profile of the contract so the limit is adequate from the outset.
