Construction Underwriting Has to Follow the Draw, Not Just the Bank Statement
Contractor files need project-level evidence: draw timing, lien waivers, retainage, inspections and payment delays, not only bank-statement deposits.
Construction contractors do not break underwriting models only because their credit scores are weak. They break them because the cash cycle is tied to draws, retainage, inspections, change orders, lien waivers, subcontractor payments and delayed upstream cash. A contractor can show strong deposits and still be one unpaid pay application away from payroll stress. Source stack: Built's May 2026 construction-loan documentation work, the American Bankers Association's May 2026 lien-waiver guide, Construction Dive's subcontractor cash-flow coverage, the Federal Reserve Banks' 2026 Small Business Credit Survey, and FTC small-business-financing guidance. The freshest signal is not a single default headline. It is the way construction-finance sources are all pointing to the same operating problem: payment and documentation gaps are not back-office clutter. They are repayment evidence. “Construction loan documentation rarely fails all at once. It fails slowly, across dozens of small decisions that each seemed reasonable at the time.” Built Team, The Hidden Cost of Scattered Construction Loan Documentation, May 2026 Operator read The draw file is the credit file. For a construction merchant, bank statements tell only part of the story. The better question is whether the current draw package, inspection record, lien-waiver trail and receivables timing support the repayment cadence being offered. The load-bearing question is timing A contractor may have revenue booked, invoices out and work in progress, while cash is still trapped upstream. Retainage can hold back final dollars. Change orders can sit in dispute. An inspection delay can freeze the next draw. A supplier bill can come due before the owner releases funds. Construction Dive, citing Billd's 2025 National Subcontractor Market Report, reported that subcontractors waited 56 days on average for payment even though general contractors believed payment occurred around 30 days after a pay application. The same coverage said 43% of subcontractors lacked enough working capital for unexpected expenses or project delays. “A single non-compliant lien waiver can leave your institution exposed to costly mechanics liens and legal liabilities.” American Bankers Association / Land Gorilla, The Definitive Guide to Lien Waivers, May 2026 That matters for MCA, RBF and broker files because daily or weekly collections can remove cash from the same operating window that needs to fund labor, materials, equipment rental and subcontractors. A short-term advance may solve a mobilization gap. It may also turn a payment delay into a second problem if repayment does not flex with project receipts. What a bank statement misses Generic cash-flow review can mistake construction deposits for available margin. A large deposit may include reimbursed materials, pass-through subcontractor costs, mobilization funds or a draw that has already been committed. A low ending balance may reflect a normal project cycle rather than immediate distress. The file has to explain the job, not just the account. For Plutus readers, the practical distinction is simple: probability of default and loss severity are not the same. A contractor with delayed receivables may still be a good credit if the claim stack, lien position, draw controls and repayment timing are clean. A contractor with strong recent deposits may be weak if unpaid subs, missing waivers, equipment liens, tax issues or stacked advances sit ahead of the funder. Signal What it can prove What to verify before funding Recent deposits Cash arrived from a customer, owner or GC Whether the deposit is margin, reimbursement, draw proceeds or money already owed to subs and suppliers Draw history Project cash is being released by milestone Inspection status, budget reconciliation, change orders and next expected release date Lien waivers Payment chain may be clearing Conditional versus unconditional status, through date, sub-tier coverage and whether payment actually cleared Retainage and receivables Earned revenue may still be unpaid Aging, dispute status, customer concentration and whether repayment fits the collection window Existing liens and UCCs Other creditors may sit ahead of recoveries Tax liens, equipment finance, prior positions, supplier claims and payoff timing The evidence stack for contractor files The underwriter does not need to become a project manager. But the file should preserve enough project-level evidence to explain why the repayment source is real. That usually means the project schedule, budget, contingency, draw history, inspections, lien-waiver practice, receivables aging, customer concentration, insurance, subcontractor exposure and existing debt stack. “For each construction draw, lenders should require a completed draw request form, current lien waivers from all contractors and subcontractors, an independent inspection report confirming work completion, an updated project budget reconciliation, and any applicable change orders.” Built Team, Construction Loan Monitoring: Hidden Cost of Scattered Docs, May 2026 The Federal Reserve Banks' 2026 Small Business Credit Survey gives the broader credit context. Small firms are still seeking financing for operating expenses, approvals remain uneven, and rising costs remain a central financial challenge. Construction adds a sharper timing layer because expenses are often paid before the next cash event arrives. “The SBCS is not a random sample; results should be analyzed with awareness of potential biases that are associated with convenience samples.” Federal Reserve Banks, 2026 Report on Employer Firms That caveat is useful. Public small-business data can frame the market, but it cannot replace merchant-level proof. For construction, the source of repayment should be tied to a job, a draw, a receivable or a verified payment stream rather than a broad industry assumption. Where MCA and RBF can fit, and where they can hurt Fast working capital can be useful when the use case is narrow: mobilization, materials for a verified job, a short receivables bridge, a seasonal equipment repair, or a gap between completed work and an expected payment. The problem starts when fixed withdrawals are sized from recent deposits without mapping who has the first claim on those deposits. The FTC has warned that small-business financing products can use different terms and repayment structures, including products with weekly or daily repayment and MCAs tied to future receivables. That does not make every advance inappropriate. It does mean construction files should be especially careful about matching collection cadence to project cash receipts. “Online companies offer a wide range of products. Some involve flat fees, rather than interest, or may require weekly or even daily repayment.” Federal Trade Commission, Small business financing: Staff Perspective outlines issues Operator read Product fit should follow the cash event. If repayment depends on a draw in 45 to 60 days, a daily fixed pull may be the wrong shape even when the contractor looks busy. If repayment can flex with verified receipts, the same merchant may be financeable with a cleaner structure and lower servicing friction. A cleaner contractor underwriting habit For construction merchants, start with the job and work back to the bank statement. Which project produced the cash? Which obligations attach to it? Which draw or receivable will repay the financing? Which parties sit ahead of the funder if the job stalls? What happens if the next inspection, permit, change order or owner payment slips by two weeks? That is the difference between generic cash-flow scoring and contractor underwriting. One reads deposits. The other preserves the evidence that explains whether those deposits are actually available to repay. Keep the funding file connected in Plutus
