"Mareaka, I reviewed our profit and loss statement we get from our accountant, and it looks profitable, but something is still off—what are we missing?"
Your profit and loss statement might look great on paper — but if you’re not breaking down jobs by crew or service type, you could be losing money without even realizing it.
Your revenue isn’t the truth — your job costs are.
Let’s get into it — because this week’s not about more sales, it’s about knowing which jobs are actually making you money.
Why total revenue can lie — and gross profit tells the real story
How your P&L should guide pricing, labor, and material decisions
Simple ways to use your reports as a tool, not a trophy.
Before we dive into it, let me introduce myself if we haven’t met yet.
I’m Mareaka from Bunch Accounting, and I specialize in helping roofing and HVAC business owners like you make confident, profitable decisions.
Roofers and HVAC owners love seeing those big sales numbers.
But top-line revenue doesn’t tell you who’s really making you money.
If you’re not tracking gross profit per job, you’re flying blind.
You might think you’re crushing it, but your margins could be leaking faster than a bad flashing job.
Your P&L is more than a report — it’s a decision-making tool.
When you read it right, it tells you which jobs, crews, or services are actually profitable.
Here’s where most contractors go wrong: they only look at total income and total expenses.
That’s like checking the scoreboard without watching the game.
You might have one crew consistently finishing under budget and another constantly running over on labor.
You might be pricing HVAC installs right, but losing margin on service calls.
Until you track job costs — materials, labor, subs, permits — against the specific revenue for that job, your P&L is just a guess.
To start seeing the truth in your numbers:
Track every job separately. Use QuickBooks Projects or Job Costing software to record income and expenses per job.
Review Gross Profit % per job. That’s what tells you which work is worth repeating.
Identify margin killers. Over-time, material waste, and underbidding are the silent profit leaks.
When you start comparing gross profit per job instead of just total income, you’ll finally see where your business is winning and where it’s bleeding.
A roofing client was pulling in $2M a year but couldn’t figure out why cash was always tight.
We job-costed their projects and found one crew was consistently 12% less profitable than the others due to longer tear-off times and higher waste.
By addressing that crew’s process, they added $80K in profit that year — without adding a single new job.
Your P&L is more than a trophy — it’s a tool. It’s not there to make you feel good about hitting sales goals; it’s there to help you make better business decisions.
When you start reading your numbers like a CFO, you stop guessing and start leading..
