We're a small shop (2 employees), and about 75% of our orders are from existing customers and sent to us via email. The email is read into our ticketing system (we use OTRS), which we use to track and prioritize jobs. We work up quotes manually, in Quickbooks or Excel, depending on the complexity and type of job. We then bill from QB and flip back to OTRS to close the ticket. My question is this -- is anyone using an integrated system that doesn't cost an arm and a leg to read in emailed orders, track them, then invoice them?
