Contractor Cash Flow and Retainage

You finish the framing, submit your pay application, and the check arrives for ninety percent of what you billed. The other ten percent stays with the owner or general contractor. On one job that is an inconvenience. Across four or five active projects, it is a pile of earned money you cannot spend, while your crews, material suppliers and insurance carrier still expect to be paid on time.

Retainage is a normal part of construction, and it is not going away. What separates contractors who stay comfortable from those who scramble is how they plan for it: in the contract, in the billing process, and in the cash forecast. This guide covers the mechanics and the practical habits.

How retainage works

Retainage, sometimes called retention, is a portion of each progress payment that the payer withholds until specific milestones are met, typically substantial completion or final completion. The percentage is set by the contract and, on some public work, by statute. Ten percent is a commonly seen figure, but contracts vary, and some reduce the rate after the job reaches a certain percent complete.

Here is a hypothetical example. A $400,000 subcontract with 10 percent retainage holds back $40,000 over the life of the job. If you bill $100,000 in a month, you receive $90,000 and $10,000 is added to the retainage balance. By the final month, tens of thousands may be waiting on punch list items and paperwork.

Why it squeezes cash harder than it looks

The squeeze comes from the gap between costs and collections. Labor is paid weekly, materials often within thirty days, and your own subcontractors may be waiting on you. Meanwhile, your pay application may take weeks to approve, then net-30 or longer to pay, and then ten percent is kept back. Your margin on the job might be around the same size as the retainage itself, which means you are effectively fronting your profit.

Retainage also flows downhill. If you are a subcontractor, the general contractor may hold retainage from you, while you may be allowed or required to hold retainage from your own trades. Check your contract to see whether the retainage you owe down the chain is tied to when you are paid.

Negotiate and document before you sign

The best time to manage retainage is before the work begins. Many contractors successfully negotiate better terms, especially on longer jobs. Read the payment clauses with an attorney if the job is large, since contract language and state rules differ.

Items worth asking about include:

• A lower retainage percentage once the job passes a milestone such as 50 percent complete.
• Release of retainage for your scope when your work is finished and accepted, rather than waiting for the whole project.
• Retainage on stored materials and whether it can be reduced.
• A defined timeline for releasing retainage after final completion.
• Whether a retainage bond or other substitute is allowed in place of cash withholding.

Run a tight billing process

Cash arrives only after a pay application is accepted, so errors and delays cost you directly. Submit on the date the contract specifies, make sure the schedule of values matches the contract, and attach everything required, such as certified payroll, insurance certificates, lien waivers and change order documentation. A missing waiver can stall the entire payment.

Track every change order in writing and get approval before doing the work. Unapproved extra work is a classic source of receivables that never get paid. Keep a simple aging report for each job showing billed, paid, retainage and amounts in dispute, and review it weekly.

Forecast the retainage you are owed

Add a line for retainage to your cash-flow forecast, but be conservative about when it arrives. Closeout can drag on punch lists, inspections, warranty documents and owner approvals. Rather than assuming retainage comes in the month after you finish, assume it arrives later and ask what happens to your payroll if it comes later still.

A good test is to calculate how many weeks of operating expenses your outstanding receivables plus retainage represent compared with your cash on hand. If most of your assets are money held by other people, you have a liquidity risk even if the business is profitable on paper.

Bridging the wait

Some contractors bridge the retainage gap with a line of credit, invoice factoring on approved pay applications where the payer's terms allow it, or working capital. The right fit depends on the contract, whether the receivable can be assigned, and how much the job's margin can absorb in costs. Consider what you would pay for the money and compare that with the cost of delaying a supplier or missing a bid.
