See erplain in action

We are running a boat yard in the Caribbean with a hydraulic workshop and wanted an inventory system that also produced invoices. I looked online at various options and erplain seemed to tick all the boxes. I can't recommend erplain highly enough, it's so easy to use, the invoices can be created quickly and immediately emailed to the client.
