- [FAQ](https://docs.payflow.appfleece.com/faq): Browse the questions below or use the sidebar. For platform constraints and workarounds in depth, see Limitations.
- [Why does Payflow keep the cheapest shipping option first?](https://docs.payflow.appfleece.com/faq/cheapest-shipping-first): Shopify checkout expects the cheapest eligible normal shipping option to remain the default first option. Payflow keeps the cheapest rates first so delivery reordering stays aligned with Shopify checkout behavior. You c
- [COD fee not showing, still showing after removal, or wrong amount?](https://docs.payflow.appfleece.com/faq/cod-fee-not-working): Fee not showing at checkout 1. COD Setup is active — open Payflow → Cash on Delivery Setup and confirm the status is Active. 2. Keyword match — the shipping rate name must include the keyword configured in COD Setup (e.
- [Why are credit card methods different in the US and Canada?](https://docs.payflow.appfleece.com/faq/credit-card-methods-us-canada): On US and Canada stores, customizing credit card methods (e.g. Visa, Mastercard as separate entries) requires Shopify Plus. Other payment methods can be customized on all plans. This behavior comes from Shopify’s checko
- [Does Payflow apply to draft orders?](https://docs.payflow.appfleece.com/faq/draft-orders): Yes when the customer completes checkout from a draft order link. It does not apply when a merchant builds an order manually inside Shopify admin — that flow does not run Shopify Functions.
- [Why did hiding PayPal from Express checkout also remove it from the payment list?](https://docs.payflow.appfleece.com/faq/express-checkout-behavior): Shop Pay, PayPal, Apple Pay, and Google Pay appear in two places at checkout: the Express checkout row (top of the page) and the payment method list (after the address step).

- [Does Payflow take a commission on COD fees or orders?](https://docs.payflow.appfleece.com/faq/payflow-pricing): No. Payflow does not take any commission, percentage, or per-order fee from your checkout — including COD fees. The COD fee is implemented as a Shopify shipping rate that you create in your own Shopify admin → Settings
- [How can I offer a discount for a specific payment method (e.g. prepaid)?](https://docs.payflow.appfleece.com/faq/payment-method-discounts): Why this isn't possible automatically Shopify evaluates discounts before the customer picks a payment method. When the discount function runs, no payment method has been selected yet — so there is no way for Payflow (or
- [Can I charge a percentage fee on the order (e.g. 3% COD)?](https://docs.payflow.appfleece.com/faq/percentage-fee-cod): Not as a true percentage line item. Fees tied to cart total must use flat amounts, typically on a shipping rate with order-amount tiers. Payflow’s percentage-to-tiers calculator (in the Help center and Cash on Delivery (
- [Can I rename Shop Pay, PayPal, or Apple Pay?](https://docs.payflow.appfleece.com/faq/rename-branded-payment-methods): Not the display name. Methods that show a brand logo at checkout cannot be renamed (a Shopify platform rule). You can still hide or reorder them. Payflow warns you in the editor if you try to rename one.
- [My rule isn't working — what should I check?](https://docs.payflow.appfleece.com/faq/rule-not-working): Work through this checklist whenever a customization does not behave as expected. 1.

- [Can I target shipping rates by their actual price?](https://docs.payflow.appfleece.com/faq/shipping-rate-price-targeting): Yes. Delivery Customization can target the actual checkout price Shopify provides for each shipping rate, not only the rate name shoppers see. This is useful when the rate amount is more reliable than the title: hide f
- [How many rules can I save?](https://docs.payflow.appfleece.com/faq/shopify-rule-limits): Shopify allows 25 active and 25 testing rules per customization type. In Payflow, that includes Payment customizations, Delivery customizations, Checkout rules, and Payment instructions where Shopify exposes the correspo

- [Tiered COD & Payment Fees by Order Amount](https://docs.payflow.appfleece.com/guides/tiered-fees-by-order-amount): Shopify cannot charge shipping as a percentage of the cart — each tier stores a flat price only.
