Construction Company Working Capital & Bridge Financing in Boston, Massachusetts

Scan the list below, find the situation that matches yours — slow GC payments, a payroll shortfall, a material deposit due before your next draw — and go straight to that guide. Each one covers qualification criteria, typical rates, and how to apply.

What to know before you pick a path

Boston's construction market runs on long payment cycles. Public work through MassDOT or the MBTA can stretch net-60 to net-90, and private GCs often push subcontractors to the same schedule whether their contract requires it or not. That gap — between when you pay labor and materials and when the check arrives — is the core problem every product below is trying to solve.

The four practical options, compared:

Product	Best fit	Typical APR	Speed to fund	Min. credit
SBA 7(a) working capital line	Established firms, lower cost priority	8.5–11%	30–45 days	640+
Bank / credit union line of credit	Firms with 2+ years of strong financials	8–20%	2–4 weeks	680+
Online working capital loan	Speed priority, fair credit	15–45%	1–3 days	580+
Invoice factoring	Specific receivables, no new debt	1–5% fee per invoice	1–3 days	Flexible

SBA 7(a) loans are the lowest-cost path if you can wait. The SBA guarantees up to 85% of the loan, which lets participating lenders offer rates in the 8.5–11% range on amounts up to $5,000,000. The catch: you need 24 months in business, a 640+ FICO, and 30–45 days of patience for approval. They're the right tool for a planned line of credit going into a large project — not for covering payroll next Friday.

Bank and credit union lines sit in the same tier. Boston has a dense network of community banks and credit unions that actively lend to contractors — East Cambridge Savings, Rockland Trust, and Eastern Bank among them. Rates run 8–20% APR. Underwriters will want 12 months of bank statements, a minimum debt service coverage ratio of 1.25x, and total debt service below roughly 43–50% of gross monthly revenue. If your books are clean and your receivables are documented, this is the path to build toward.

Online working capital loans close in 1–3 business days and accept lower credit scores, but you're paying for that speed and flexibility — 15–45% APR is common. Use them surgically: cover a specific, short-term gap and pay them off as soon as the draw clears. Rolling short-term high-rate debt month to month is what kills otherwise healthy contractors.

Invoice factoring is worth understanding separately because it isn't a loan. You sell a specific receivable — say, a $120,000 draw request approved but not yet paid — at a 1–5% discount and receive 80–90% of face value in 1–3 days. The factor collects from your customer. There's no debt on your balance sheet, and credit score matters far less than your customer's creditworthiness. For subcontractors waiting on slow GCs, this is often the cleanest tool. Contractors doing federal or state government contract work will find that some factors specialize in public-sector receivables and are familiar with assignment-of-claims paperwork.

What trips people up in this market:

• Applying for the wrong product under time pressure. An SBA loan is not a payroll solution if you need funds in a week.
• Thin documentation. Boston lenders — online and traditional — will ask for 12 months of bank statements. Have them organized before you start.
• Stacking multiple high-rate products. If your monthly debt service starts crowding that 43–50% ceiling, new lenders will decline you regardless of revenue.
• Ignoring equipment as a separate line item. If part of your liquidity crunch ties back to a machine purchase, equipment financing for Boston excavation contractors prices differently from working capital — typically lower rates with the asset as collateral — and shouldn't be bundled into a working capital ask.

Minimum annual revenue of $250,000+ is a practical floor for most unsecured products here. Firms below that threshold should look at SBA microloans (up to $50,000) or factoring rather than trying to force a fit with products designed for larger operations.

Contractors elsewhere in the country solving the same problems will find the same product logic applies — the Albuquerque guide and the Anchorage guide both cover regional lender differences worth reading if you're working multi-state projects or comparing market conditions.
