Contract Financing: Funding Work Between Payment Milestones
A finished milestone does not always release cash immediately. Compare funding for the work, customer acceptance and the payment interval that follows.

The crew can finish a stage of work on Friday and still be weeks away from customer payment. Someone may need to inspect the installation, approve the milestone and process the invoice before cash reaches the business. Meanwhile, payroll and supplier bills continue.
Contract financing should cover that interval as well as the work itself. For an established business taking on a larger project, the decision is whether a dedicated contract facility, an existing credit line or another working-capital structure can fund the required costs without draining cash from other jobs.
Find the event that actually releases payment
Read the payment schedule alongside the scope of work. A date in the project plan is not necessarily the date the customer must pay. Identify what has to happen before each installment becomes payable: delivery, installation, testing, written acceptance or another agreed condition.
Then separate three dates in the cash plan: when the work is expected to finish, when the invoice can be submitted and when payment is expected. If the customer has a review period, include it. If part of the price is held until final completion, keep that amount separate from earlier receipts.
This matters when negotiating the project, too. A mobilization deposit or more frequent progress payments can reduce the amount that needs financing. Ask whether those terms are commercially workable before assuming the whole gap must be borrowed.
If an upcoming contract would stretch your current resources, discuss the contract financing request with Sussex Capital. Share the expected start date and the first significant spending commitment; you can begin the conversation while the remaining details are being organized.
Choose a facility that funds the work you must perform
A contract-finance proposal should identify the costs it will actually cover. Supplier purchases, employee wages, subcontractors and overhead do not necessarily receive the same treatment. Ask whether funds go to the business or directly to approved payees, and what must be verified before a draw is released.
A facility designed mainly to pay a goods supplier may not solve a labor-heavy installation project. Our purchase order financing versus factoring comparison explains the distinction between financing fulfillment and financing an invoice after delivery.
SBA-backed structures may also be worth discussing where the business and transaction qualify. The SBA describes Contract CAPLines as financing costs tied to specific contracts, including allocable overhead, with revolving or non-revolving structures. Its Working Capital Pilot offers monitored credit lines that can support large contracts or projects. These are program examples, not a promise that a particular provider will offer either structure for your request.
An existing business line of credit may be simpler to use if its permitted uses and available capacity fit the job. The tradeoff is shared capacity: money committed to the new contract cannot simultaneously cover the company's other obligations. Compare the proposed peak draw with what the business needs for its ordinary operations.
Sussex's financing programs include purchase order and contract finance, business credit lines, SBA financing and receivables-based options. The useful comparison is how each proposed structure handles this contract's costs, payment conditions and repayment source.
Do not count unfinished work as available invoice funding
A signed contract, recorded revenue and an eligible invoice are different things. If payment still depends on completion or acceptance, confirm whether a receivables provider will advance against that amount at all.
The OCC's asset-based lending handbook identifies unbilled receivables among assets commonly excluded from borrowing eligibility. It also explains that eligibility varies with the borrower, collateral, industry and lender. That banking guidance is a reason to ask specific questions, rather than a universal rule for every financing provider.
For a staged contract, ask how the proposal treats progress invoices, customer holdbacks, disputed work and unapproved changes. Do not build the funding plan around financing a final installment until its eligibility is confirmed.
Where contract financing is expected to be repaid through a later receivables facility, establish how the two arrangements connect. The payoff amount, reserves, fees, collateral rights and control of collections must fit together. Otherwise, completing the work can expose another cash shortage instead of clearing the first one.
Size the request around the deepest cash requirement
Consider a hypothetical established commercial installation business evaluating a $1.2 million contract. Before its first progress payment arrives, it expects $620,000 of project cash outflows. A $120,000 customer deposit and $100,000 of business cash available for this project leave a $400,000 funding requirement before financing costs.
Suppose customer acceptance takes longer than planned while the business incurs another $80,000 of scheduled project costs. The requirement becomes $480,000 before financing costs. Nothing about the contract's face value has changed; the timing has changed the cash needed to perform it.
Those figures are planning assumptions, not an approved facility or a borrowing limit. Extend the schedule through final collection, add financing charges and repayments, and test whether a later stage creates a higher requirement. The business contribution also needs to leave adequate cash for existing work.
The supporting working-capital forecast guide explains how to lay out receipts and payments. For this decision, use the forecast to compare actual draw conditions and repayment dates, rather than selecting a facility solely because its stated limit exceeds $400,000.
Protect the margin and the rest of the business
Financing can bridge timing, but it adds costs to the contract. Compare the expected margin after financing charges, extra supervision, likely rework and any other costs the original estimate omitted. A delay can extend financing costs while also consuming crew capacity needed elsewhere.
Be especially careful with changes to scope. Show an approved change and an anticipated change separately; additional work does not automatically produce an agreed additional payment. Where contract language is unclear, have the appropriate adviser resolve it before relying on that receipt.
