[Pharo-dev] Invoice management

Ciao, I hope this email and relative question does not create problems to the list. 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
