Flat rate vs QuickShipper — what's the difference

You choose the delivery method in „Delivery method“ between two tiles. „Flat rate“ — you charge one fixed fee and arrange delivery yourself (no courier is booked automatically). „QuickShipper quote“ — you charge the live courier price and a courier is booked automatically once the order is paid. The „QuickShipper quote“ tile stays disabled („Connect QuickShipper below first.“) until you connect QuickShipper below. Remember: in QuickShipper mode, if no live price comes through, your „Flat fee“ is used as the fallback — so still set a sensible flat fee.
