Hello elk, Thanks for taking time to respond to me. Heard for point 1, it is therefore necessary to each price change of the same article, create a new reference. Regarding point 2, I understood that we could use the barcode scanner to fill the field during the item creation. However, I find the article search inconvenient, especially since the field used for the search is based on the barcode, whereas a search from the description of a product is more meaningful (we are human beings, not machines ;-) I was thinking of making a small paper catalog with the articles and their associated barcodes, which would have allowed me to scan this one to do the research. What do you think ? Maybe this could be a suggestion for improvement of the software? How do you propose this to NCH Software?
