The Cooter Muck OMS is a rails app that tracks sales, invoices and inventory, as well as store inventory and sell-through. It ties into both ERP systems though EDI and the highrise API to tie together sales opportunity, invoicing, customer care and followup and order / shipment tracking and payment management.

It's not SAP, and it's not terribly pretty, but it's worked well for us as it's grown over the last 5 years.

It's a standard rails app, hosted on Heroku. Not a heck of a lot to say, but the cascading invoice / payment calculation stuff is interesting.

This internal tool has been tracking our sales since the company was started.
