Do commission-free ordering platforms still charge per order?

Check each one. Some charge a monthly plan, and card payments carry the payment provider's fee. Menuthere charges no per-order fee.

• Shopify adds 0.2% to 2% when you use a third-party payment gateway.
• Square Online's card payments cost 2.9% to 3.3% plus 30 cents, and it has paid plans.
• With Menuthere, the only per-order cost is your gateway's fee, and only if you turn online payments on.
• Ask: is there a commission, a per-order fee, an order limit or a setup fee?
