For proposal checkouts Sprwt applies its platform service fee using the Sprwt Proposals Service Fee (Amount $) value (plus any variable sales fee) instead of the fee used for regular online orders, once the subtotal is above the platform's minimum-cart thresholds. It appears in the Totals card and at checkout as Service Fee; if you enable Show Processing and Service Fees Separately (Business: Cart), the card-processing fee is listed on its own Processing Fee line, otherwise both are combined under Service Fee. Whether the customer or your kitchen absorbs processing fees follows your normal processing settings.
