Return Pfand in Shopify POS (Apply Return Credit)

This new POS flow lets staff return Pfand deposits without manual discount codes.

How it works

1. Open the Pfand POS tile and tap Return Pfand.
2. Select the returned bottles (fixed fees only).
3. Review the total return credit.
4. Tap Apply Return Credit to add a negative line item to the cart.

The cart total is reduced by the exact deposit amount that the customer returned.

Notes

• Only fixed Pfand fees are listed (percentage fees are excluded).
• The return credit is added as a custom sale line item titled Pfand Return Discount.
• If the return credit exceeds the cart total, the POS total can go negative. We can add a safeguard later if needed.
