Hi Dario, maybe you remember I have developed in VSE ST a full package (MIDA) for company management (bookkeeping, stock management, invoicing...). I am sure you can find what you are looking for and I believe it will not be very hard to port what you need to Pharo.

A dear friend asked me if I was able to handle the invoice management: 1 ) create the document with some items 2) print and save the document 3) have the possibility to make some queries on the documents Someone realized something in this direction based on Smalltalk ( Pharo ) ? A base development with possibly to customize...... Thanks for any considerations. Dario
