I'm working on a Cocoa-based ERP that uses PostgeSQL on the backend. Invoicing is among the things it does. Yes, it is possible to do write such a thing, though you will have to work out a preferred way to (un)persist your data objects to/from the database (or use someone else's framework that does this). Apple hasn't addressed the need for Cocoa to interact with database servers, so you'll be on your own in this dept.

Hi

I am a 4D developer for almost 15 years.
In the beginning of this year I am studding the idea of chancing my range of Invoice Programme made in 4D to XCODE/Objective-c 2.0/Cocoa.

One of the reasons is the very expensive cost that 4D has when you work in Client/Server Mode. And the constant need of upgrade 2003 to 2004 to v11 and so one in future. The other is the idea of a new project that merge iPhone and Mac in a invoice program.

Its easy and is the interface will be nice.
Can I made a invoice program in cocoa.
Is there any one made a program with this framework(Xcode;cocoa;objective-c 2.0)

My invoice program have modules of TPV, Code Bar its a small ERP

Best regards
