Hii

What is the best inventory management app for small businesses?

Because I can't seem to find one that has it all and is free to use.

Some pointers:

- Generate SKU's codes

- Scanning to add inventory

Hope you guys can guide me and or recommend me other ways to do this.

I've found EasyScan app, but 29,99 a month is a bit steep imo.
