We don’t do generic bookkeeping. We work with HVAC, plumbing, electrical, and construction contractors, along with cash-pay chiropractic and MDVIP practices, who are tired of bookkeepers that don’t understand their business. Get job costing, cash flow clarity, and Xero-powered dashboards — without lifting a finger.
Jeremy Brewer isn’t a generic accountant who read about HVAC. He ran calls as a licensed paramedic and turned wrenches in the field before building 911 Bookkeepers.
Our clients are HVAC, plumbing, electrical, and construction contractors, plus cash-pay chiropractic and MDVIP practices. No restaurants, no retail — just businesses whose numbers we actually understand.
Questions get answered the same business day. No waiting a week to find out if your payroll numbers make sense.
Month-to-month. We earn your business every month by being genuinely useful — not by locking you in.
You’ll get a monthly summary you can read in 5 minutes — not a stack of numbers to decode yourself.
Generic bookkeepers don’t understand job costing, seasonal cash flow, or what a slow August means for your December. We do.
Clean, reconciled books in Xero every month with plain-English reports you can actually read.
Know exactly what you made (or lost) on every job, truck, and technician — not just at year-end.
Live Looker Studio dashboard with a 90-day cash projection so you’re never blindsided by a slow season.
Get your chart of accounts, classes, and tracking categories built right from day one.
“I finally know what I’m actually making on each job. Jeremy set up job costing in Xero and now I can see my margins in real time — not six months later at tax time.”
“The cash flow dashboard alone is worth it. I can see exactly what’s coming in for the next 90 days and plan around the slow season instead of panicking.”
“Jeremy actually understands the trades. He’s not just a bookkeeper — he speaks the language and knows what questions to ask.”
Chart of accounts, job costing, maintenance agreements, cash flow, and tax structure in one place.
