All accounts are simultaneously both shopper and seller accounts. By clicking the three lines (menu button) on the top left of the app, you can select ‘VIEW AS SHOPPER/SELLER’ at the bottom of the pop out menu.
To know which mode you are in, notice the Pigee button on the bottom footer menu changes colour. Pink is for Seller and blue is for Shopper.
You have access to both modes so that you can both make purchases and also sell items without the need of a separate account.
There are two other variations to be aware of. Only whilst in Seller mode can you be the owner or staff member of a shop. You can only be the owner or staff member of one shop at a time.
