Are you busier than ever and still not sure where the money goes?
Plumb Line partners with HVAC, electrical, and plumbing owners to turn real financials into clear decisions—sharper profitability, honest benchmarks, and a business worth keeping or worth selling.
What Plumb Line Does
You didn't start your business to stare at spreadsheets. But the financials are where the real story lives—what's working, what's leaking, and what's possible.
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.
We build from the compliance layer—clean books and taxes handled by Seneca—to give you the advisory layer that most trades businesses are missing entirely.
How do you know if you’re charging enough?
How We Help
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.
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.
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.
Does your accountant tell you what happened, but not what to do about it?
Who It's For
We work with owner-operators who've built something real and want to make it stronger. Our sweet spot is established businesses doing $1M–$5M in revenue across the mechanical and electrical trades.
If you're good at your trade but want a sharper handle on the business side—we're built for exactly that conversation.
Good Fit
Plumb Line is an advisory practice of Seneca. Seneca handles the compliance layer—taxes and bookkeeping—so your advisory is built on a foundation we trust completely.
