How can I enable an option to cover processing fees at checkout on Square Online?

Hi.

We are an Australian not-for-profit charity and we are setting up Square to take online donations. We are wondering if there is a way that we can ALWAYS have appear an option for the customer to select to pay either a calculated or set fee to help us pay processing fees?

We have seen other charities have something like "Would you consider paying an extra $2 to help us with a processing fees" and customers can tick a toggle box to either opt in or out.

Is this possible with Square and, if so, how would we do this so that it appears for EVERY checkout transaction?

Thanks

I worked out a workaround by using a modifier that lists two options - yes, happy to contribute a set amount or no, don't want to contribute. If anyone knows of any better way, please let me know 🙂

Hi @FatalLordes,

Currently, Square doesn't support adding surcharges to Square Online sales. We understand there’s demand for this feature, and this thread is a good one to follow for feedback and announcements on surcharges in Australia.

Your question is unique since it sounds like you're considering an optional donation as a modifier to help cover online card processing fees, rather than as a charitable donation or for goods or services. I’d recommend caution here, especially for charity-related transactions, as it’s essential to stay compliant with ACCC regulations on surcharging. For a more sustainable approach, we recommend incorporating processing costs directly into the pricing of your items and services. 🙂

To be safe side, I suggest reaching out to our Support Team to confirm that using modifiers in this way aligns with compliance requirements. You can call support on 1800 760 137 (Mon - Fri, 9 AM - 5 PM Melbourne time), or contact us via online chat or email. See the below steps.

1. Sign in to your Square account.

2. Head to our contact page https://squ.re/3AWfZs2.

3. Go to "Other", then "I don't see my issue".

4. Click "Message us", "Email us" or "Call Us".

Or, if you see the new chatbot help flow, type “support” to bring up a list of contact methods.
