## 💵 Set a Custom Total and Read the Discount Breakdown

Key in the total you want the guest to pay and let the app back-calculate the discount, then read what each line on the bill means.

### 📝 Steps
1. On an open order, tap **Pay**.
2. In the **Functions** row, tap **Custom Total**.
3. Using the keypad, enter the new total in **Target Amount**, then tap **Confirm**.
4. The app adds a flat **Discount** equal to the difference between the current total and your target amount.

If the order has no items, you'll see **No items available for discount**. If your amount is not lower than the current total (or is negative), you'll see **Target amount must be less than current total** — enter a smaller value and try again.

### 📝 Read the bill breakdown
Below the order list, the running totals break down into:
- **SUBTL** — subtotal before tax, service charge, and discount.
- **GST** — tax amount (shown only if tax is enabled; the label may follow your configured tax name).
- **SVC** — service charge (shown only if service charge is enabled).
- **ROUNDING** — the rounding adjustment.
- **DISC** — total discount applied, including any custom total discount.
- **TIP** — tip amount (shown only when a tip has been added).

The **Discounts** section on the **Pay** screen lists each discount by name; tap the gray ✕ next to **Discount** to remove your custom total and restore the original price.

> **💡 Tip:** A custom total always adds a new flat discount — it never edits an existing one. Remove it from the **Discounts** list if you change your mind.
