About
routebook isn't a SaaS pitch deck. It's the field service ERP I wish I'd had when I was the Director of Finance watching our HVAC techs run jobs off three spreadsheets and a clipboard. The software we paid for wasn't built for them. So I built one that was.
From the operator who built it
"I was the Director of Finance at a regional general contractor. I watched our HVAC division run on three spreadsheets, a whiteboard, and a clipboard. We paid for software that wasn't built for them. The dispatcher had her own system. The tech had his own system. The bookkeeper had hers. None of them talked. Job costs lived in my head."
"I left to build the platform that would have saved us. routebook is what I would have paid for. Same brain that's been on your side of the desk runs the company today."

Why this matters
Right now, when you call us, you get me. Samuel. (615) 631-3790. That doesn't scale forever, but it's the deal today — and it's part of why early shops choose routebook over enterprise software with a 1-800 number and a tier-2 support queue.
One tier. One price. The whole platform. We don't gate features behind "contact sales." If you can read the pricing page, you know what it costs to run routebook for the next year. That's the whole pitch.
Whatever you're on now, we pull it. Customers, jobs, properties, equipment history, AR. Two weeks typical. No "implementation specialist." No five-figure rollout invoice you didn't see coming.
We build what owners ask for. Not what enterprise IT departments score on a Gartner quadrant. Every feature shipped lately came from a phone call with a customer who ran into a thing routebook didn't do yet.
