I use infix to amend my sales orders which SAP Small Business generates for me. I use that document to confirm orders to customers (with dollar amounts) and for production (where I have to eliminate the $ amounts for confidentiality reasons). We don’t write separate production orders.
It also comes in handy for all the PDFs I receive from clients where I have to amend text. It saves me time as i don’t have to go back to the client and ask for word docs.
Overall a great product!
Wishing you all the best,
