American Express

American Express (Amex) is accepted by default on all storekit stores, allowing customers to pay with their Amex cards alongside Visa and Mastercard.

Availability

American Express is enabled by default for all stores and works in all regions where storekit Payments is available.

Some merchants prefer not to accept Amex due to higher processing fees. To disable Amex for your store, contact support.

Amex can be disabled on a per-store basis. If you have multiple stores, let support know which stores you’d like to disable it for.

Reason	Consideration
Higher fees	Amex typically charges higher processing fees than Visa/Mastercard
Customer base	If few of your customers use Amex, the higher fees may not be worth it

Reason	Consideration
Customer preference	Some customers exclusively use Amex for rewards
Higher spending	Amex cardholders often have higher average order values
Business customers	Many corporate cards are Amex

If you’re unsure, we recommend keeping Amex enabled. The convenience for customers often outweighs the slightly higher processing fees.
