I'd like to know if it is possible for an employee to see stock in other stores, so a client can be redirected when a certain product is not available anymore, but in another store.
You can give access rights to your employes to enter to your back office and at least check the option for "Items" to be able to access your item list.
After that, your employee can enter your back office to check stock levels across different stores.
And, by giving them access rights to the back office, you also provide them with access to enter the Loyverse Dashboard app with their own email and password.
The dashboard app could be even more convenient to check your inventory.
If you only gave them access to the "items," they will not see any sales details in dashboard app, just the inventory.
