Your shop name ends up with the service history on their report. No Customer names are on the report, just service history and where it was done. It can work in your favor. The theory goes that if they buy the car then they will continue to take the car to your shop since you have serviced it before. The vin decoder is the single biggest time saver for us. We used to have to go to every car, write the vin, hope I can read my own writing and put it in the computer.
Now, punch in the plate, Vin, year, make, model, engine, all come up and fill themselves in the RO. May not be needed for some but if your a high volume shop doing repairs & service, tires and oil changes it's great. Now when you look up parts and labor using Epicor or whoever's catalog parts are correct (most of the time) and labor. SO much easier than the manual route.
