Winning a big commercial electrical job feels great. It also changes the shape of your cash flow in ways that catch many contractors off guard. Commercial work usually comes with progress billing and retainage, two concepts that can leave a profitable job starving your bank account until well after the work is finished.
Progress billing means you invoice as the job moves along, typically monthly, based on the percentage of work completed. You usually submit a pay application showing the contract amount, what you have billed, and what you are requesting for the period. This is usually based on a schedule of values that breaks the contract into line items like rough-in, fixtures, and gear.
Retainage is a percentage of each payment, often 5 to 10 percent, that the owner or general contractor holds back until the project reaches completion or another agreed milestone. It exists to give them leverage that the work will be finished properly. The percentages and release terms vary by contract, so read yours carefully.
Suppose you win a $200,000 electrical contract with 10 percent retainage. If you bill your way through the whole job, $20,000 is held back. And that $20,000 is not profit sitting around, it is a chunk of the money you already spent on payroll and materials. If your margin on the job is 15 percent, or $30,000, a third of the profit is stuck in retainage until the end, and sometimes beyond it, if closeout drags on. These figures are only an example.
Now layer on payment timing. If you invoice at the end of the month and the owner pays 30 to 45 days later, your labor and material costs are well ahead of your cash. Larger jobs can require serious working capital even when the contract is solid.
Retainage should not disappear into general receivables. In your books, track retainage held on each job as a separate receivable, so you can see how much has been withheld, what has been released, and what is outstanding. A report by job, showing contract amount, billed to date, retainage held, and cash collected, is one of the most useful views a commercial electrical contractor can have.
Keep your schedule of values and pay applications consistent with the books. Mismatches between what you billed and what you recorded create headaches at closeout, when the owner wants everything reconciled before releasing the final payment.
You will sometimes hear about front-loading the schedule of values, meaning assigning larger values to early work like mobilization and material purchases so you are paid sooner. There is a legitimate version of this, since materials and setup really do cost money early, and an aggressive version that can cause trouble if it distorts the true progress of the job. Stay honest and transparent, and make sure your numbers can be defended if questioned.
Many retainage problems come from sloppy closeout. Punch lists linger, final documentation is missing, and lien waivers or warranty paperwork are not turned in. Each of those gives the other party a reason to delay release. Build a closeout checklist and begin working it before the job is fully finished. Track the date retainage is eligible for release and follow up on it, since nobody else will remember.
If you are managing multiple large jobs, keep a running list of retainage balances and expected release dates. It is part of your cash forecast, even though it is often forgotten. You may also want to talk with your attorney about notice requirements and lien rights on Louisiana projects, since deadlines matter.
If commercial jobs are a major part of your business, plan funding for the gap between costs and collections. A line of credit sized to cover your largest job's float, a discipline of turning in pay applications promptly, and realistic cash forecasts all help. Our post on separating service from construction results explains how to see whether these jobs really earn their keep.
Retainage and progress billing are part of the deal on commercial work, but they do not have to be a surprise. Understand the terms, track retainage separately, bill promptly and accurately, work the closeout early, and plan for the cash gap. Done well, large jobs can grow your business without starving it.
