Sometimes you have to take a different approach - you can setup your vendors like they are items but, no prices - when a customer picks an item, you select the vendor's name from the POS App screen - then enter the item's price, quantity and in the Note Field, enter what the item is. At the end of the event, you can run a Transaction Report to see what was sold. Hint, instead of the canned Transaction Report, use the Export feature - when you Export a report to a CSV file you get more information (shows more fields) than the canned Report. This is especially helpful as you want to see the Notes Field so you know what item or items were sold. Suggest using Excel to manipulate the CSV file data for creating a cleaner looking Report. Some things to keep in mind - all of the transactions will be associated with the Square Account that's used so it's going to look like income to that Account - if your organization has a Square Account already that will make things easier rather than using a member's Square Account. Also ensure that the Account is setup for Taxes (if applicable) ahead of time which will save some checkout time. There's other things to consider too - like what hardware you plan to use - for example - a smart phone with a Magstripe Reader or better yet, an iPad with a Contactless and Chip Reader. Last, best to have an internet connection or at least hotspot capability. (Note, you should be able to just use Square's POS App which is free - no need to spend extra money.)
