How can I add a credit card fee only on POS system sales?

Topic summary

A merchant seeks to add credit card processing fees specifically to POS transactions, not all sales.

Current Limitations:

  • Shopify POS lacks native functionality to automatically apply fees only to credit card payments
  • The platform charges merchants processing fees but doesn’t offer built-in customer surcharge options

Available Workarounds:

  • Create a “credit fee” product visible only in POS and manually add it to applicable transactions
  • Use custom sales under cart modifiers to apply variable percentage-based fees
  • Third-party apps like Feesly Surcharge and Chargly offer automated solutions

User Concerns:

  • Multiple participants express frustration that this isn’t a core feature
  • Third-party apps criticized for adding checkout time, requiring internet connectivity, and lacking reliability
  • Comparison made to competing POS systems that include percentage-based surcharges as standard functionality

Status: The discussion remains open with a Shopify representative acknowledging the feature request will be forwarded to developers, but no timeline provided for native implementation.

Is there a way to add a credit card fee on the POS system? I don’t want it on every sale, just on the credit card sales and I can’t seem to find a way to do it.

Hey, @xtremerconline .

Thank you for reaching out!

Currently, there isn’t a way to charge your customers a specific credit card fee on the point of sale system. Shopify charges the merchant a small fee to allow you to accept major credit cards online and through your POS system. However, there are a few ways around this! You could create a “credit fee” product and only have it available to your POS system; then, you can add this product to the order whenever you want to charge that fee. Another option could be to add custom sales under cart modifiers; this allows you to enter in a custom amount to charge your customers. This is a good option if you want to charge different percentages of the total sale as a fee and not a fixed amount.

I will happily pass along your feature request to our developers as I know this would be a helpful feature to add to our POS system.

Please let me know if you have any further questions!

IM USING FEESLY SURCHARGE FOR POS

How do you navigate to the custom cart modifiers? Thanks!

All third-party apps add time to the checkout and don’t work consistently.

Every other POS system I use/consult on can easily add a % upcharge to the shopping cart.

PLEASE IMPLEMENT THIS!!!

We recently build an app dedicated to adding credit card and other fees specifically for Shopify POS. Would love your feedback on it!

If you have any issues. Happy to dig in. Support@sasquatchstudio.co

cheers

Don’t want a third party app that relies on a web connection and slows down transactions. This needs to be a core functionality!
