Now let's process some sales! This chapter shows you step by step how to complete your first sale — from a simple direct sale to table service with split payment.

Direct Sale (without tables)

The simplest way: select articles, check out, done.

Step 1: Select Articles

1. Switch to the POS (click "Kasse" in the header bar)
2. You see the article groups as colored tiles
3. Tap a group (e.g., "Getränke" / Beverages)
4. Tap an article (e.g., "Cola 0,3l")

The article appears on the receipt (right side):

  Bon
──────────────────────────────
  1× Cola 0,3l          3,50
──────────────────────────────
  Gesamt:                3,50

Step 2: Add More Articles

• Same article again? Simply tap it again → the quantity increases
• Different article? Switch group and tap
• Change quantity? Tap the article on the receipt → enter quantity
• Article with options? For articles with extras (e.g., pizza toppings), the options dialog opens automatically

  Bon
──────────────────────────────
  2× Cola 0,3l          7,00
  1× Weizen 0,5l        4,20
  1× Pizza Margherita    9,50
──────────────────────────────
  Gesamt:               20,70

Step 3: Check Out

1. Tap "Zahlen" (Pay) (or the total amount)
2. Select the payment method
3. The receipt is printed (if a printer is configured)

3. The remaining amount is settled with a second payment method (e.g., "EC-Karte" / Debit card)

You can combine any number of payment methods: cash + card, card + customer credit, cash + voucher, etc.

Customer Credit

1. Select the customer
2. Select "Hausbon" (House tab) as the payment method

Split Payment

Splitting by Items

Table 5 has ordered: 2× Cola (7.00 €), 1× Weizen (4.20 €), 2× Pizza (19.00 €)

Guest A wants to pay: 1. Tap the items for Guest A (e.g., 1× Cola + 1× Pizza) 2. Amount: 12.50 € 3. Select payment method → Receipt is printed

Guest B pays the rest: 1. The remaining items are already selected 2. Amount: 17.70 € 3. Select payment method → Receipt is printed → Table is freed

Splitting Evenly

Alternatively, you can divide the total amount by the number of guests and charge the same amount each time.
