Advisory built on
your actual numbers.

Sometimes you just need a numbers guy (or lady). That's us. You didn't start your business to stare at spreadsheets. But the financials are where the real story lives: what's working, what's not, and where the opportunities are.

First, we make sure your books are clean, accurate, and up to date. That foundation is essential for diagnosing what's going on and where to go next.

Plumb Line translates your P&L, cash flow, and job costing into clear, actionable guidance so you can focus on the work and the team while your business grows the right way. And it's something many trades business owners are missing. That's the difference between the owner that's stuck at the same size, putting out fires versus the owner whose bottom line has doubled.

How do you know if you’re charging enough?

Far too often business owner-operators undercharge and leave money on the table. But keeping prices too high can inhibit your growth. It’s a balancing act that needs to consider your costs, the local market environment, your competitors, your positioning, among other factors. It requires a complex analysis with specialized expertise. That’s exactly where Plumb Line comes in.

We give you clear recommendations for growth so you can make informed decisions with confidence in your numbers.

The guidance that actually moves your business forward.

01

Financial Advisory

We dig into your P&L, cash flow, and job costing to find where margin is hiding and where it's leaking. Practical recommendations grounded in your real numbers.

  • Profitability analysis by service line and job type
  • Cash flow forecasting and seasonal planning
  • Growth strategy grounded in what the numbers actually say
02

Industry Benchmarking

How does your overhead compare to other shops your size? What should your gross margin look like on service calls? We answer those questions with real comparative data.

  • Performance benchmarked against peers in your trade and revenue band
  • Overhead, labor burden, and margin targets calibrated to your market
  • Actionable gaps identified, not just numbers on a page
03

Exit Readiness

Whether you're five years out or just starting to think about it, we help you build a business that's attractive to buyers—clean books, strong margins, and systems that run without you.

  • Business valuation awareness and improvement roadmap
  • Owner dependency reduction and documentation
  • Buyer-ready financials when the time comes

Does your accountant tell you what happened, but not what to do about it?

That's the difference between accounting and advisory. Plumb Line gives you the straight answer and the next move.

Built for trades owners
who want more.

We work with owner-operators who've built something real and want to make it stronger.

If you're good at your trade but want a sharper handle on the business side, we're built for exactly that conversation.
