Pros

“Long learning curve, English parts descriptions ( modifier,modifier,modifier,object ). ”

Charles D.

Owner and Operations

“The integrations with Auto Vitals is very good and has helped our shop grow the bottom line.”

Ken A.

Owner / CEO

“My favorite aspect of AMS Protractor is all my accounting is integrated. ”

Doug D.

Owner/Service Writer/Technitian/Janitor

Pros

“Some things that I would like to note are the limited invoice template options (enabling qr code for custom invoices, editing certain fields, like moving phone number below email for the default template, etc.)”

Albaraa A.

Owner

“The customer portal is a huge advantage because customers can approve estimates online, view invoices, check repair status, and keep track of service history without constant back and forth communication.”

Tyler S.

Automotive Technician

“It’s an all in one app, I can have my inventory, invoices, reports, and the added labor guides is a huge bonus, and LOVE the live links for customers so I don’t have to send them multiple times if they want to change something, love have I can enter the vin and the vehicle information come up. ”

Chester H.

Owner

Cons

“A bit hard to navigate if not familiar with the software. ”

Doug D.

Owner/Service Writer/Technitian/Janitor

Cons

“Also from time to time, it will glitch and not allow you to add appointments to personal calendar so you will have to log off and log back in for it to be fixed.”

Sandra G.

President

“I encounter formatting glitches and data field errors when attempting to use either the built-in ARI "custom" templates or my own custom-designed versions.”

Dustin E.

Owner Technician

“What I like least about ARI is the constant changes that can sometimes make it difficult to keep up with new processes, features, or updates.”
