I want to make a webapplication invoice program.
The programs needs to add/modify customers and articles, to create invoices.
These invoices have to printed on local printer.
Is this a good way to use B4i or should I use something else?
And how do I put the resulting file(s) on the server of the provider?
Definitely a B4j job, I would even suggest ABMaterial as it will dynamically adapt to the user browser, being it a desktop or mobile device (OS independent)
