Won a big contract? Funding the start-up costs before the first payment

A big new contract means materials, staff and gear paid upfront, with the first payment weeks away. How to size the start-up cash gap and fund it without risk.

Quick answer

A new contract often needs materials, staff, equipment and insurance paid weeks before the first invoice is settled. Size the gap by mapping costs and payment milestones over the contract's first few months, negotiate a deposit or early progress claim, then fund what's left with a short-term cash loan, a cash line or property-backed cash repaid from contract payments.

Key points

  • The first invoice is often 30 to 60 days after work starts.
  • Mobilisation costs (materials, labour, gear) come first.
  • Ask for a deposit or an early first milestone.
  • Lenders like a signed contract with clear payment terms.

Winning the big one is a great feeling. Then reality arrives: you need to buy materials, put on extra staff, maybe hire or buy equipment, and get insurance sorted, all before you’ve sent a single invoice. And the first payment, once you do invoice, might be 30, 45 or 60 days away.

That’s the start-up gap. It’s one of the most common reasons good businesses need cash fast.

What costs come before the first payment?

Cost When it’s paid Notes
Materials and stock Before or at the start Often the biggest item
Extra labour Weekly or fortnightly from day one Plus super with every pay run
Equipment hire or purchase At the start Consider hire for short contracts
Insurance and licences Before you start Some contracts require higher cover
Travel and accommodation Ongoing For regional or interstate work
Subcontractors On their terms Often shorter than your client’s

The gap runs from the first of these costs until the client’s first payment clears, and it often grows for a month or two before payments catch up.

How do you map the gap?

  1. List each cost with the date you’ll pay it.
  2. List the contract’s payment milestones, with the date you’ll realistically be paid (add a week or two to what the contract says).
  3. Add your normal business income and costs alongside.
  4. Track the running balance.

The cash gap calculator does this for you and shows the deepest point and how long it lasts. That’s the amount and term to fund.

How can you shrink it before borrowing?

  • Ask for a mobilisation payment or deposit. Many clients will agree, especially if you explain the materials cost.
  • Negotiate an early first milestone. A smaller first claim at two weeks rather than a big one at six.
  • Line up supplier credit. A trade account with 30-day terms means materials are paid closer to when you’re paid. See our supplier terms guide.
  • Hire before you buy. For a one-off contract, hiring equipment keeps cash in the business.

How do you fund the rest?

  • Short-term cash loan. Ideal for a defined gap with the contract payments as the exit. See short-term business loans.
  • Business cash line. Useful if the contract has many stages and the gap rises and falls.
  • Property-backed cash. For larger contracts, with interest prepaid or added so there are no monthly repayments while you’re mobilising. See property-backed cash.

Lenders will want to see the signed contract, the payment schedule and your normal bank statements. A clear margin on the job helps too.

Building a start-up budget the lender will believe

A clear budget helps you as much as the lender. Keep it to one page:

Line What to include
Contract summary Client, value, start date, duration
Payment schedule Each milestone or claim, amount and expected date paid
Upfront costs Materials, equipment, insurance, licences, mobilisation
Ongoing costs to first payment Wages and super, subcontractors, travel, hire
Your margin Expected gross profit on the job
Funding needed The deepest point of the gap, plus a buffer
Exit Which payments repay the funding, and when

If the contract is with a large organisation, note their usual payment practice as well as the contract terms. A lender knows that “30 days” on paper and “30 days” in practice can differ, and a realistic schedule builds confidence.

Watch for these risks

  • Payment terms longer than your suppliers’. You’ll carry the difference for the whole contract. See slow-paying invoices.
  • Retention money held back until completion, which reduces each payment.
  • Variations that you fund before they’re approved.
  • One client becoming most of your work. If they pay late, everything stalls.

An illustrative example

Illustrative only. A Darwin electrical contractor wins a $480k fit-out contract paid in monthly progress claims on 30-day terms. Materials, two extra electricians and a scissor lift hire cost about $140k before the first claim is paid. The client agrees to a small mobilisation payment. A short-term facility covers the rest and is repaid from the second and third progress claims.

Turn the win into cash flow

You’ve done the hard part by winning the work. Let’s make sure cash doesn’t hold you back. The enquiry takes about a minute and won’t leave a mark on your credit file. We won’t share your details around a long list of lenders. A real person reads about your contract and calls to talk through the start-up costs.

Please be accurate about the contract value, payment terms and your current turnover. It’s what lets us match you to the right funding first time.

Frequently asked questions

Can I borrow against a contract I've just won?

You can use the contract as evidence of where repayment will come from. Unsecured cash is still sized mainly on your existing turnover, while property-backed cash can fund larger amounts with the contract as the exit.

Should I ask the client for a deposit?

Yes, especially for materials-heavy work. Even a modest mobilisation payment or an early first milestone shrinks the gap and shows the client is committed.

How do I estimate start-up costs?

List materials, extra labour, equipment hire or purchase, insurance, licences and travel for the period before the first payment arrives. Add a buffer for the first payment being late.

What if the contract is bigger than my business has handled before?

Be upfront about it. A lender will want to understand how you'll deliver, your margins on the job and the payment terms. A clear plan makes a bigger contract easier to fund.
