Accounts Payable

In Plain English

The money a company owes to its subcontractors and suppliers for work already done but not yet paid.

Definition

Accounts payable (AP) in construction represents the amounts a contractor or owner owes to subcontractors, suppliers, and vendors for goods and services received but not yet paid. Managing AP efficiently protects subcontractor relationships, avoids mechanics lien filings, and maintains cash flow. AP aging reports show outstanding invoices categorized by the number of days past due.

Why It Matters in Bidding

How a contractor handles payables directly shapes its standing with the subs and suppliers it relies on to staff future bids competitively. A reputation for paying on time earns better unit pricing and first call on scarce trades, while chronic late payment invites lien filings and bid premiums that erode margin. Estimators feel this indirectly: vendor quotes carried into a bid reflect the company's payment history.

Example

After award, a GC schedules its concrete sub's $120,000 invoice in the AP system tied to the owner's pay-app cycle so the sub is paid the week after funds clear, keeping the crew on the next phase.

Frequently Asked Questions

Vendors and subs build payment history into their quotes. A contractor known for prompt payment receives sharper pricing and gets priority during busy seasons, letting the estimator carry leaner numbers. Slow payers see padded subcontractor quotes or refusals to bid, which raises the base price and weakens competitiveness on hard-bid jobs.
Pay-when-paid clauses let a GC defer subcontractor payment until the owner pays the corresponding amount, aligning payables with receivables to protect cash flow. Enforceability varies by state, and many courts limit it to timing rather than eliminating the obligation. Subs scrutinize these clauses closely before bidding because they shift owner non-payment risk downstream.
Aging reports group unpaid invoices by days outstanding so a contractor sees which obligations are current versus 30, 60, or 90 days past due. This flags lien-exposure risk, helps prioritize payments to critical subs, and supports cash-flow forecasting. Lenders and sureties also review aging when underwriting credit lines and bonding capacity.
