Hello there.
I can develop for you a Ms Access database so you can have all your data stored in a safe place. (require a Office Pro licence)
One benefit to use ms Access is that you can create as many label as you want, and design so many templates like Avery has. Also, you can sort, filter and print a group of products.
My offer is, develop for you this database with at least 4 label templates and a main window to manage all products.
(you can export from excel so many product as you wish and keep it centralized)
Please let me know and let's discuss!
PS: Other way is to Print labels by using Excel data in a Word mail merge. More easy and more cheap for you. (50 AUD for 4 Word templates)
