Bookkeeping for Electricians: Progress Billing, Job Costing and QuickBooks

Bookkeeping for electrical contractors means tracking each job's labor, materials, permits and subs against what you billed, including jobs billed in stages. The essentials are a QuickBooks setup that separates service from project work, progress billing with retainage tracked, crew hours tied to jobs, and money set aside for quarterly taxes and slow stretches.

What's different about bookkeeping for an electrical contractor?

Bookkeeping for an electrical contractor is different because cash and work don't line up. A service call gets paid on the spot, but a remodel, addition or tenant fit-out can run for weeks with wire, gear and labor going out long before the final payment comes in. If the books only show deposits and bills, a busy month can look profitable while the bank account runs dry.

Labor is the other big difference. Electrical work is labor-heavy, crews mix journeymen and apprentices at different rates, and hours on a long job get spread across weeks of timesheets. If those hours aren't tied to the job, you can't tell whether the $18,000 basement job made money until it's far too late to do anything about it.

How should electricians set up QuickBooks?

Electricians should set up QuickBooks with service and project income on separate lines, labor and materials as job costs, and every bill and timesheet tagged to a job or customer. That gives you a profit and loss you can read at a glance and job reports that show which projects paid and which ones didn't.

How does progress billing work for electrical jobs?

Progress billing for electrical jobs means splitting a larger job into stages and invoicing each one as it's done, usually a deposit, then rough-in after inspection, then trim and final. It keeps cash coming in while materials and labor go out, and it gives both sides a clear record of what's been paid.

1. 1

   Set the stages in the quote.

   For example: 30% deposit to order gear, 40% at rough-in inspection, 30% at final. Put them in writing before work starts.

2. 2

   Invoice the day each stage is reached.

   A rough-in that passed inspection on Tuesday should be billed on Tuesday, not when the job wraps up.

3. 3

   Track retainage separately.

   If a GC holds back a percentage of each payment until the project closes, record it as money owed to you, and put the release date on your calendar.

4. 4

   Bill changes as change orders.

   The extra circuits and the moved panel get their own signed change order and invoice. See change orders.

5. 5

   Chase on a schedule.

   Progress invoices are easy for customers and GCs to let slide. Follow up on every one until it's paid.

That exchange is a sample to show the flow, not a real customer. The wording, timing and number of reminders are set up with you. If you want to see how long you're waiting for money overall, try the DSO calculator.

How do you job cost a panel upgrade?

Job cost a panel upgrade by adding up the panel and breakers, wire and fittings, labor hours at your burdened rate, the permit and any utility or sub costs, then comparing the total to your price. Do it for every upgrade for a few months and you'll see which ones ran over, usually because of surprises behind the wall.

The labor line is where electrical job costs drift. A crew that spends two extra hours tracing an old knob-and-tube run without anyone logging it makes the job look better than it was. Crew timesheets tied to jobs fix that; see billable hours. For the method in general, read job costing and labor burden.

What taxes should electrical contractors plan for?

• Quarterly estimated tax. The IRS says sole proprietors, partners and S corporation shareholders generally need to pay estimated tax if they expect to owe $1,000 or more when they file. See quarterly estimated taxes for contractors.
• Self-employment tax. Owed in most cases once net self-employment earnings reach $400, at 12.4% for Social Security plus 2.9% for Medicare, per the IRS. See self-employment tax and S corp vs. LLC for contractors.
• Payroll taxes. With journeymen and apprentices on payroll, you're withholding and paying employment taxes. See payroll taxes, and keep employment tax records at least 4 years, per the IRS.
• Subs and 1099s. Trenching and low-voltage subs may need a Form 1099-NEC. See 1099s for subcontractors and W-2 vs. 1099.
• Sales and use tax. How materials and gear are taxed depends on your state and on whether the work is a repair or a capital improvement. See sales tax on labor vs. materials.

What BRIX does for an electrician's books

BRIX keeps the paperwork that feeds the books moving: invoices go out by stage or at job close, unpaid ones get followed up, customers, invoices and payments sync to QuickBooks, crew clock-ins become payroll-ready timesheets, and expenses, 1099 subs and sales tax stay organized with reminders before estimated tax dates. BRIX doesn't file taxes or give tax advice.
