Working Capital Lines of Credit for Growing US Companies — How to Fund New Contract Growth

Winning a major new contract should be cause for celebration. For many growing US companies, it's also the moment a serious cash flow problem becomes unavoidable. The contract is signed, the work begins, but the revenue doesn't arrive for 30, 60, or 90 days — while payroll, materials, subcontractors, and overheads need to be funded right now.

A working capital line of credit is the most effective tool for bridging that gap — and for businesses with strong contract pipelines, it can be structured quickly and at scale. This guide explains how it works, who qualifies, and how US-based advisors, brokers, and CPAs can refer clients who need this type of facility.

The Contract Growth Problem

US companies across technology, manufacturing, construction, logistics, professional services, and government contracting face the same fundamental challenge when they scale: growth consumes cash before revenue arrives. The faster a company grows, the more acute the problem becomes.

Consider a mid-sized staffing firm that wins a new contract to supply 50 additional staff to a Fortune 500 client. The contract is worth $3 million over 12 months. The client pays on 45-day terms. The payroll runs weekly. From day one, the company is funding several hundred thousand dollars in payroll before it sees a single dollar of revenue from the new contract — on top of its existing operational costs.

Without a working capital facility in place, the options are unattractive: turn down growth, draw on personal reserves, or approach a bank that will take weeks to respond and likely decline based on a balance sheet that doesn't yet reflect the new contract's value.

💡 The core issue: Traditional bank lending is backward-looking — it assesses what a business has done, not what it is contracted to do. A specialist working capital line is structured around the forward-looking reality of a company's contracted revenue and receivables pipeline.

What Is a Working Capital Line of Credit?

A working capital line of credit is a revolving facility — a pre-agreed borrowing limit that a company can draw on, repay, and draw again as needed. Unlike a term loan (which is disbursed in full and repaid over a fixed schedule), a revolving line gives the business maximum flexibility: draw what you need when you need it, repay it when your customers pay you, and the capacity resets.

Interest is charged only on the outstanding drawn balance, not on the full facility limit. A company with a $2 million facility that has $600,000 drawn at any point pays interest on $600,000 — not the full $2 million. This makes it a highly efficient form of financing for businesses with lumpy or seasonal cash flows.

How the Facility Is Structured

Working capital lines for growing US companies are typically structured in one of three ways depending on the nature of the business and its revenue:

Who This Works Best For

Working capital lines are not a one-size-fits-all product, but the following profiles consistently represent the most compelling applications:

Government Contractors

Federal, state, and municipal government contracts are among the most attractive receivables a lender can hold — the counterparty risk is essentially sovereign, payment terms are predictable, and contracts are typically long-running. A staffing agency, IT services provider, or construction company with a confirmed government contract can often access a working capital facility faster and at better terms than a comparable commercial business. The SBA's own Working Capital Pilot Program delivered $150 million in support to US manufacturers in early 2026 — testament to how mainstream this financing has become for the government contracting sector.

Technology and SaaS Companies

Tech companies with enterprise contracts often invoice quarterly or annually — but their engineering and operational costs are monthly. A working capital line smooths that mismatch, particularly for companies scaling rapidly after a significant new enterprise deal or following a round of investment that came with aggressive growth targets.

Staffing and Professional Services Firms

Staffing firms are perhaps the most natural fit for receivables-based working capital finance. Weekly payroll funded by monthly or 45-day client invoices creates a structural cash flow gap that grows in direct proportion to the company's success. A well-structured receivables facility grows automatically as the business wins more clients — the facility scales with the revenue, rather than requiring repeated renegotiation with a bank.

Manufacturing and Distribution

Manufacturers and distributors dealing with large purchase orders — particularly those supplying to major retailers or industry prime contractors — often need to fund significant materials and production costs before they ship a single unit. Purchase order finance or a receivables line that activates as soon as goods are shipped and invoiced is the standard solution for this sector.

Construction and Infrastructure

Construction companies managing multi-phase projects face front-loaded costs — labour, materials, plant — against back-loaded milestone payments. A working capital line provides the buffer to fund mobilisation and early-phase costs without stalling a project or accepting punitive cash retention terms from the main contractor.

Business TypeCommon TriggerTypical Facility Size
Government contractorNew federal or state contract signed$500k – $10m+
Staffing / professional servicesNew enterprise client win$250k – $5m
Technology / SaaSEnterprise contract, annual billing gap$500k – $15m
Manufacturing / distributionLarge purchase order received$500k – $25m+
ConstructionNew project mobilisation$1m – $20m+

What Lenders Look For

Specialist lenders assessing a working capital application focus on a different set of criteria than a traditional bank:

📋 Preparation matters: The quality of presentation to a lender directly affects both the speed of approval and the terms offered. A well-packaged submission — covering the business background, contracted revenue, customer quality, and facility requirement — consistently outperforms a raw application, even for identical businesses. This is where an experienced broker adds the most value.

The Role of the Advisor, CPA, or Broker

For many growing US companies, the first person they turn to when a financing need arises is not a lender — it's their CPA, their attorney, their commercial insurance broker, or a trusted business advisor. These professionals often know their clients' businesses in detail, understand the strategic context of a new contract win, and are well-placed to identify when a working capital facility could unlock significant growth.

The challenge is that most CPAs and general business advisors don't have direct relationships with the specialist lenders who structure these facilities — and the mainstream banking relationships they do have are often ill-suited to the agility and scale that a growth financing situation requires.

This is where partnering with a specialist finance broker adds real value — both for the client and for the referring advisor. The broker handles the full structuring, lender selection, negotiation, and placement process. The advisor makes the introduction, remains involved in the client relationship, and earns a referral fee on completion.

How the Process Works

For a US company (or their advisor) approaching us about a working capital facility, the process is straightforward:

  1. Initial discussion. We start with a conversation about the business, the contract or growth trigger, and the funding requirement. No paperwork at this stage — just a clear picture of whether the facility makes sense and what structure is appropriate.
  2. Information gathering. We collect the relevant financial information — typically the last 2 years of accounts, recent management accounts, aged debtor reports, and the contract documentation if the facility is contract-based.
  3. Lender selection and submission. We identify the most appropriate lenders from our panel for the specific situation and present the deal in a structured, professional credit submission. We manage all lender correspondence.
  4. Credit approval and term sheet. Most working capital facilities can be approved in principle within 5–10 business days of a complete submission. The term sheet sets out the facility limit, pricing, and key conditions.
  5. Legal completion and drawdown. Once terms are agreed, legal documentation is completed and the facility is activated. The company can draw funds immediately on completion.

Pricing — What to Expect

Pricing on US working capital facilities varies significantly based on the structure, the lender, and the risk profile of the borrower. As a general guide:

Facility TypeTypical Pricing (2026)Fees
Receivables / invoice finance linePrime + 1.5% – 3.5% p.a.0.5%–1.5% arrangement fee
Contract / PO finance1.5% – 3.5% per 30 days on drawn balanceStructuring fee varies
Unsecured revolving credit8% – 18% p.a. depending on profile0%–2% origination fee
Asset-based lending linePrime + 1% – 3% p.a.0.5%–1% arrangement fee

For the right business with strong receivables and a creditworthy customer base, pricing at the sharper end of these ranges is achievable. A well-presented deal with a compelling credit story consistently commands better terms than a raw application — which is why the quality of the introducing advisor's initial framing matters as much as the underlying financials.

Frequently Asked Questions

What is a working capital line of credit?

A working capital line of credit is a revolving facility that allows a business to draw funds up to a pre-agreed limit, repay them as cash comes in from customers, and draw again as needed. Unlike a term loan, it's flexible — the company only pays interest on what it draws, and the facility remains in place throughout the agreed term. It's designed to smooth the gap between when costs are incurred and when customers pay.

Who qualifies for a working capital line of credit in the US?

Typically, US companies with at least 12 months of trading history, demonstrable revenue (usually $500,000+), and a clear growth trajectory — such as a recently signed contract or purchase order. Lenders focus heavily on the quality of the company's receivables or the creditworthiness of the counterparty on a new contract. Strong contracts with government entities, blue-chip corporations, or institutional buyers are viewed most favourably.

How is a working capital line different from a bank overdraft?

A bank overdraft is typically limited in size, can be recalled at any time, and is approved conservatively by high street banks. A specialist working capital line is structured specifically around the company's receivables or contract pipeline, can scale with the business, and is arranged by lenders who understand growth financing. It's also more reliable — a formal facility cannot be pulled overnight in the way a bank overdraft can.

Can a company use a working capital line to fund a new government contract?

Yes — and this is one of the most compelling use cases. Government contracts are typically long in payment terms but highly creditworthy. A working capital line secured against a confirmed government contract (or a receivables facility drawn against invoices raised to a government counterparty) is a well-established structure with strong lender appetite in 2026.

How much can a US company borrow on a working capital line?

Facility sizes range significantly depending on the lender and the company's revenue. At the lower end, facilities from $250,000 to $1 million are available for established small businesses. Mid-market companies with strong contract pipelines can access $1 million to $25 million. Larger bespoke facilities above $25 million are available for the right companies and counterparties.
