CASE STUDY · ELECTRICAL CONTRACTOR

39 PERCENT GROSS. 6 PERCENT NET.

QUICK ANSWER

A $3.1M electrical service contractor came to us running the business from fear. A partner separation had pulled six figures out of the company, and everything after that was scrambling. The numbers said the work was fine: gross profit at 39.17 percent, net at 6.07. That leaves 33 points of overhead in between, about $1.03M a year on $3.1M of revenue. She wasn't losing money on jobs at all. She was losing it on structure, and no amount of selling harder closes a hole that size.

This owner is not the usual case. She used to run a weekly profit and loss broken down by job, so she knew what good looked like. The crisis took the routine away, and once you're working from the bank balance each morning the structural problem gets no attention at all.

THE SITUATION

A $3.1M ELECTRICAL SUB. RUNNING ON THE BALANCE, NOT THE NUMBERS.

A $3.1M commercial and residential electrical service contractor. A partner separation had taken six figures out of the business, and since then decisions were being made from the morning bank balance. Real money sat frozen in an unpaid invoice and a bank error still working through resolution, receivables were stretching past 60 days, and the collections list ran 80 accounts deep with no way to rank them.

THE PROBLEM

THE JOBS WERE FINE. THE STRUCTURE WAS NOT.

39.17 percent gross profit on service electrical work is a healthy number. It says the pricing is right, the technicians are productive and the work is being sold well. Then 6.07 percent net says almost none of that reaches the bottom.

Thirty three points of overhead is the whole story, and on $3.1M that is about $1.03M a year. A contractor in that position can double the sales effort and change nothing, because that cost sits outside the work.

On top of it she was carrying debt from a previous business and vehicle debt, both of which service out of the same overhead the business was already too heavy to carry.

WHAT WAS REALLY WRONG

AN 80 ACCOUNT LIST WITH NO ORDER TO IT.

The collections problem came down to sequencing, and never to diligence. Eighty accounts on one list, all of them equally urgent because nothing ranked them, and invoices going out in batches after work completed, never on completion.

The overhead problem was built the same way. $1.03M a year is not one line item, so there was nothing obvious to cut. It needed the whole cost base read against revenue before anything could be targeted, which is what turned an intimidating number into 4 identifiable points.

Four points on $3.1M is about $124,000 a year, and it moves net from 6.07 percent to roughly 10.1. That clears the 10 percent minimum we work to without selling one additional job.

Cash Control System
THE INTERVENTION

WHAT CHANGED, WEEK BY WEEK.

Week 1: Started cash flow forecasting to sequence who gets paid, when, and how much extra, so decisions came off a plan and not off the morning balance.
Weeks 1 to 3: Changed invoicing to go out immediately at completion, no longer in batches, and ranked the 80 account collections list so effort went where the money was.
Weeks 2 to 4: Brought accounts payable current and built the payoff order for the prior-business debt and the vehicles.
Weeks 3 to 4: Read the full cost base against revenue and identified 4 points of overhead to remove, about $124,000 a year.
Next 60 days: Removing those 4 points, and building a commercial branch alongside the service side plus a cash reserve, so net 60 terms stop being a threat.
THE OUTCOME

THE NUMBERS, NOT THE FEELING.

60+ TO 30 DAYS
Receivables, Done
CURRENT
Accounts Payable, Done
4 POINTS
Overhead Identified, About $124K a Year
6.07 TO 10.1%
Net Profit, Targeted

Thirty days. The receivables move, the payables position and the payoff order are done and hold today. The 4 points of overhead are identified and not yet removed, so the 10.1 percent net is a target and not a result. That is the honest state of this engagement and it will be updated when the reduction is complete.

WHAT THIS MEANS FOR OTHER CONTRACTORS

DOES THIS SOUND FAMILIAR?

The signature of this one is a healthy gross margin beside a thin net. If your jobs price well and your bottom line is small, that cost sits outside the work and no sales push will reach it.

The second signature is a collections list with no order. Eighty open accounts is not unusual on service work. Eighty open accounts where nobody can say which five to work this week is what turns a receivables position into a cash emergency.

The third is subtler and worth watching for. This owner knew her numbers before an event took the routine away. Capability is not the same as current visibility, and a good operator six months after a shock can be running as blind as one who never looked.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because 33 points of overhead sit between them. On $3.1M of revenue that is roughly $1.03M a year of cost that is not attached to any job. Service electrical work carries real overhead, trucks and dispatch and inventory and licensing, so a high gross margin is normal and is no protection at all. The number to watch is the distance between the two margins, because that distance is the entire operating structure of the business.
Because sequencing buys the time to do the second thing properly. Overhead reduction is a set of decisions about people, vehicles, software and commitments, and those are bad decisions to make in a week when payroll is uncertain. Getting receivables from 60-plus days to 30 or less, bringing payables current and ranking the collections list took about three weeks and turned the cash position from reactive to planned. The 4 points were identified after that, with room to remove them deliberately.
Ten percent is the minimum we work to, not the ceiling. It is the level at which a business can absorb a bad quarter, fund its own growth and pay its owner properly. This contractor moves from 6.07 to roughly 10.1 on the overhead reduction alone, with no additional revenue. Where the target sits above that depends on the trade and the revenue band, and the published benchmark rows carry those figures by trade.
