Billing by phase on electrical projects: a simple guide

Waiting until punch list to bill the whole job is a cash flow trap. You've already paid labor, materials, and overhead while the drywall sub and the inspector control your schedule. Billing by phase matches invoices to work you've actually finished — so money comes in closer to when cost goes out.

Electrical finishes in waves: rough-in, temp power, trim, devices, final ties, corrections. If you bill once at the end, your cash out (weekly payroll) and your cash in (one big check) never line up. That forces credit cards, lines of credit, or juggling slow-pay vendors — problems that a simple payment schedule would prevent.

Owners feel this as "we're always busy but the account feels tight." Busy means payroll is running. Tight means money is lagging behind work you've already done. Billing by phase closes that gap.

On typical residential or small commercial work:

• Rough-in complete / service inspection — in-wall work verified before cover.
• Trim / devices — plates, gear, fixtures after paint.
• Final inspection / sign-off — energization, labels, closeout documentation if required.

Pull a percentage at each gate that reflects the cost and risk you've absorbed at that point — not just equal thirds unless that actually matches your cost.

A common starting point: 30% deposit (commitment and early materials), 40% at rough-in sign-off, 20% at trim, 10% at final. Adjust it if you front-load expensive gear or have long-lead items — take more upfront when your exposure is higher.

Write the phases into the contract with clear completion criteria — like "passed rough electrical inspection" — so there's no argument about whether the invoice is due.

Explain once, clearly: billing by phase keeps the crew paid and material flowing. It's standard on project work, not unusual. Most homeowners understand it. Most GCs expect it.

If someone insists on end-only payment, price the risk into the bid, shorten payment terms somewhere else, or walk. Taking a full job on final-only terms is a financing decision — not a sales victory.

Put the payment schedule on the signature page, not buried in the back. People sign what they see when they're already nodding.

Inspectors move dates. Other trades slow you down. Weather happens. Communicate early: "We're done on our side for rough — inspection moved to Tuesday, so we'll invoice per contract after pass."

If your work is done but something downstream is blocking inspection, consider billing for documented completed scope — or negotiate a partial draw with the GC. The point is to avoid going silent until you're desperate. Slipped phases plus radio silence equals mistrust.

The client sees money tied to real progress. You see cash before your full exposure is out. Disputes get smaller because each phase is clearly scoped. If something goes wrong at the end, you're not trying to recover 100% of the job — just the tail.
