I've been in the signage industry for 18 years. Vehicle wraps, shopfront installs, wall graphics, site surveys, design, sales. The lot. I've driven hours to quote a job, stood in a car park writing measurements on whatever was in my pocket, taken photos on my phone, and texted them to the office, then lost half of it before I got back to the desk. I've had installers turn up not knowing where signs go or what they're going into. If it could go wrong, it has.
I've done return visits because a substrate wasn't written down. I've had jobs go sideways because the measurement on the paper didn't match what was actually on site. I've sent PDFs to clients that looked like they came from a Word template from 2009.
Every time I went looking for a tool that actually fixed this, I found two things: generic form builders that didn't understand sign work, or enterprise platforms built for chains with IT departments and $500/month budgets. Nothing built for the shop doing 10–50 jobs a month. Nothing built by someone who'd actually stood on a roof with a tape measure. So I built it.
