Built by a tinter, for tinters.

My name is Joe Volpe. I have been tinting cars for more than 18 years and I own Frederick Window Tinting in Frederick, Maryland. Every piece of software I tried over those years got me halfway there and then left me duct-taping the rest together with Google Sheets, Calendar, Zapier, and a website I built myself. Booking, pricing, scheduling, invoicing. Nothing was made for the way a real shop runs.

In September of 2025 I decided I was done patching tools that were not built for us. I locked myself in my office and started building RevFlw from the ground up. Nine months of 10 to 16 hour days. Year, Make, and Model pricing. A timeline that runs the install from check in to checkout. Online booking that does not lie about the price. Bookkeeping wired straight into the same ledger as the invoice.

I use it in my own shop every single day. Every feature exists because it solved a problem I ran into on a real install, not because a product manager thought it would be a good idea. If you run a tint shop and you are tired of stitching tools together, RevFlw was built for you. By me. By a tinter.
