How to Add Processing Fees to Your Online Store Checkout

If you run an online store, you might sometimes want to pass along certain costs like payment processing or convenience fees to your customers. This helps keep your pricing transparent and ensures your business doesn’t absorb those extra expenses. Fortunately, there’s an easy way to add these fees directly at checkout, so your customers see them clearly before completing their purchase.

📌 Why This Matters

Adding processing fees at checkout lets you recover costs related to handling payments or other services without hiding them in your product prices. It makes your pricing more transparent and ensures your business stays profitable by covering those extra fees customers incur when paying online.

✨ What’s New

  • Processing Fee Option: You can now apply a processing fee as a separate charge during checkout on your online store.
  • Clear Fee Calculation: The fee is automatically calculated based on the entire transaction amount, including subtotal, discounts, taxes, and shipping.
  • Visible on Order Summary: This fee shows up as its own line item during checkout and on the final receipt, so customers know exactly what they’re paying for.
  • Rounded Charges: Fees are rounded to two decimal places to keep everything clean and consistent.
  • Customizable Settings: You can set the percentage rate for the fee and change the label to whatever makes sense for your business.

🛠️ How to Use It

  1. Step 1: Go to your payment settings under Miscellaneous Charges.
  2. Step 2: Enable the Processing Fee option and decide on the percentage rate and label (for example, “Payment Processing Fee”).
  3. Step 3: Make sure this fee applies to your online store channel.
  4. Step 4: Save your changes—now, the fee will automatically be added at checkout for customers.

💡 Important Things to Know

  • Processing fees currently do not apply to any upsell products you might offer.
  • All fees are neatly rounded to two decimal places before they’re added to the order total.
  • Turning off this fee in settings won’t change or remove fees that were already applied to existing orders.



💡 Pro Tip

Communicating any added processing fees clearly at checkout can help maintain trust with your customers while covering the cost of payment methods, protecting your bottom line.
