The Internal store is your cafeteria and desk counter: products
players never see — water, coffee, grips, balls — each with a name, a
price and, optionally, a barcode, a photo, a description and a stock count.
Sell works with a USB or Bluetooth barcode scanner: it types like a
keyboard, so scan into the box (or type the code and press Enter) and the
line lands on the ticket; products without a barcode are one tap away in the
grid. Adjust quantities, then charge in cash or through one of your
terminals — a terminal's commission is recorded the same way as at the desk.
Sales lists every ticket of a day with per-method totals; a mistaken
ticket can be voided (its stock comes back and the row stays for the record).
These sales appear in the financial report and the money summary under
Internal store; they never touch a player's balance.
Only owners and admins with the Internal store permission see this
section — tick it in People & administration when adding or editing an admin.
