Run on Layers3D every day since the first line of it was written.
Before Layers3D, a lot of the day went to admin: retyping quotes, digging through folders for the right file, and chasing customers who sent a quote request with no file attached. The owner puts the time it gives back at about 1 to 2 hours a day, now spent on more productive work.
The shop's part-time worker uses it too. They look an order up, grab its files straight from the order instead of searching a folder for them, and send the job to a printer. Chasing files stopped being a chore: the request goes out from the order, and the file comes back onto it.
The pricing engine was calibrated on this shop's completed jobs. When it re-quoted the history it had learned from, leaving each job out in turn, its error fell from 46% to 15%. Those are the numbers the ROI page uses.
