Processing Fee on Ecommerce Store Checkout

What’s New?

Store owners can now apply Processing Fees directly on Ecommerce store checkouts — allowing businesses to pass on additional charges such as payment processing or convenience fees to customers.

Key highlights:

A new
“Processing Fee”
option is now supported for Ecommerce checkout flows.
The fee is calculated on the total transaction amount (
Subtotal - Discounts + Taxes + Shipping
).
The charge appears as a
separate line item
during checkout and on the final order summary/receipt.
Fees are
rounded to two decimal places
for consistency.
Store admins can configure the percentage and label of the processing fee under
Payments → Settings → Miscellaneous Charges → Processing Charges
.

How to Use It?

Go to
Payments → Settings → Miscellaneous Charges → Processing Charges
.
Enable
Processing Fee
and set the percentage and label name.
Ensure Ecommerce Stores is selected as an applicable channel.
Save the configuration — the fee will now automatically apply to customer checkouts.

Important Notes:

Upsell products currently do
not support
processing fees.
All fees are
rounded to two decimal places
before being added to the total.
Disabling the feature won’t remove fees from existing orders unless they’re editable.
