Access external orders (e.g. online orders) through the POS. Please note that for the external orders to be accessible in the POS they have to first be imported to Sitoo Backoffice.
Make validated returns on orders from your E-commerce. Import E-commerce orders with an External ID and additional information in the payment section to be able to search for the order in POS.
If you are using Klarna as checkout in the E-commerce then you are able to import the orders with additional data to directly update the invoice in Klarna.
