Funding for construction
Construction funding for the months between pay apps
The cash cycle
Busy and slow months
Building season runs from spring through fall across most of the country and slows in winter, though it varies by location, and Sun Belt contractors may work year-round.
How money moves
Where the cash gets stuck
What owners use funding for
- Mobilize crews and equipment for a new contract
- Buy materials ahead of a price increase
- Meet weekly payroll while a pay app is in review
- Buy or finance an excavator, skid steer or work truck
- Carry a job until retainage is released
- Cover payroll through a winter slowdown
What fits
Funding that suits construction
Business line of credit
Draw for mobilization and payroll, repay when the pay app clears, and draw again on the next job. It matches progress billing better than a lump sum.
Equipment financing
Machines and trucks secure their own financing over years, which keeps big purchases off your working capital.
Invoice factoring
Some factors buy progress billings from creditworthy GCs or owners, turning an approved pay app into cash within days. Expect extra paperwork, like lien waivers, with each invoice.
Underwriting
What funders check in construction
- Work-in-progress schedule and backlog of signed contracts
- Accounts receivable aging, including retainage owed to you
- Who you work for: GC and owner payment history, public or private jobs
- Bank deposits over recent months, which run lumpy in construction
- Tax liens, mechanics liens and judgments against the business
- Licensing, insurance and bonding status
Watch out for
Pay-when-paid clauses
Read your subcontract for pay-when-paid or pay-if-paid language before you fund against it. Under those clauses your cash can wait on a dispute you're not part of, and a funding payment won't wait with it.
Change orders and back charges
Unapproved change orders and back charges can cut a pay app after you've already spent the money. Fund against approved amounts only, and assume disputed work pays late.
Unpaid suppliers can freeze your draw
GCs often want lien waivers from your suppliers before releasing your payment. If a daily debit leaves a supplier unpaid, the waiver doesn't come, and neither does your draw.
In depth
Progress billing and the payment gap
Most commercial work bills monthly. You submit a pay app for the work done, the GC reviews it and rolls it into its own draw, and payment comes after the owner or the owner's lender releases funds. Every step adds days. Public jobs often pay on a published schedule, while private jobs depend on the owner's lender and the GC's habits, so funders weigh who sits at the top of the payment chain.
Fund the gap, not the job. A line of credit drawn for payroll and repaid when the pay app clears usually costs far less than a lump sum sitting on a daily debit. Keep your pay app log current, since funders ask what's billed, approved and paid.
Matching the product to the job
Short-term advances are built for businesses with steady daily or weekly deposits. Construction deposits arrive in lumps, so a daily debit keeps pulling money in the weeks between draws. If you use one, keep it small, tie it to an approved pay app with a firm payment date, and ask for weekly payments. A late draw with a daily debit running is exactly when owners get pushed toward a second advance.
Equipment financing suits machines and trucks, which hold value and secure their own debt. Factoring can work on progress billings from creditworthy GCs, though factors usually leave retainage out. Read MCA versus line of credit before choosing between the 2 most common short-term options.
Openbook Capital shows each offer's total payback, cost in dollars, payment schedule and estimated APR side by side, so a line, a factor and an advance can be compared on the same page.
Bonding capacity and new debt
Sureties weigh credit, capacity and character before they write bonds. A new advance with daily debits and a blanket UCC-1 can make your balance sheet look weaker right when you're bidding bigger jobs. Talk to your surety agent before you sign. Keep your work-in-progress schedule current too, since sureties and funders both read it as proof you know where each job stands.
If bonding itself is the bottleneck, look at the SBA's Surety Bond Guarantee program. It guarantees bid, performance and payment bonds issued by certain surety companies to small businesses, on contracts up to $9 million, or up to $14 million for federal contracts. It doesn't replace working capital, but it can open work your current bonding can't reach.
Questions
Construction owners ask
Do funders work with subcontractors?
Yes, many do. 1 funder we track excludes construction outright, which is why Openbook matches your file only to funders whose published criteria accept contractors.
Can I get funding against retainage?
Rarely on its own, because it isn't payable until closeout and can be disputed. Once the job is accepted and retainage is invoiced, some factors and lenders will consider it.
Should I finance equipment or rent it?
If a machine works most weeks of your season, financing usually costs less than renting over time. For a single job, renting keeps debt off your books.
Will a winter slowdown hurt my application?
Funders expect seasonal dips in construction. They look for deposits that pick back up in spring and for no stretch of negative balances or NSFs during the slow months.
Do I need to show signed contracts?
Often, yes. Funders like to see backlog: signed contracts, approved pay apps and who's paying, because it shows where the money for payments will come from.
