Custom Fees lets you add any type of additional charge to your store's checkout without writing a single line of code. From payment processing costs and handling fees to international surcharges and weight-based charges, you can automatically apply the right fee to the right order every time. Set up your rules using fixed amounts, percentages, or weight-based calculations, and fine-tune exactly when they apply with flexible conditions. There's no limit to how many rules you can create, so your fee structure can be as simple or detailed as your business needs. Pricing is straightforward: the free tier resets every month, you only pay a percentage of the fees you collect, and your rate goes down as your volume grows. Your customers see transparent, clearly labeled fees right at checkout. Stop absorbing hidden costs and start recovering your margins on every order.
