I made this utility in Java with the GlazedLists library. One of my friends helps his parents run a repair shop, and he wanted to create a utility to make the data-handling side easier. With my programming and his design and choices, we created this. This program allows you to add customers as entries, including things like contact number, broken accessory, current state etc. and you can even print out invoices and receipts.
My friend’s native language is Portuguese and he resides in Portugal, so some of the text in this program is in that language. This is partly the reason why this program is called ‘GCE’ and not something else like ‘Repair Shop Manager v1.0’. Since this is my copy of the program, the majority of it should be in English. I spelled Portuguese wrong in the first screenshot.
