I can absolutely see how setting up an automation or a tile for surcharges would help your POS order management. This is certainly possible and the best way to achieve this setup is to use an app. We have a couple of apps on theShopify App Storethat can do this on the POS. You can check them out below.
These apps have free trial periods so I encourage utilizing them to see if any of them is a good fit for your store. Bear in mind that these are third-party apps so if you have questions about them, I suggest reaching out to the app developers or app support team as they can best address any concerns you have about their apps. You can find their individual contact details on the app listing page.
How are your business and Shopify POS so far?
