Processing fees help you recover the cost of credit card transactions by adding a transparent fee to relevant payments. Using this feature, you can automatically apply a fee as a percentage of the invoice amount when members or companies pay with a credit or debit card. Processing fees apply exclusively to card payments and do not support other payment methods, such as bank transfers, checks, or point-of-sale (POS) payments.

If you manage a coworking space where credit card fees impact your bottom line, you may find this tool valuable. In this article, you will learn how to set up processing fees, apply them correctly, and understand key system behaviors when using this feature.


Summary

  • Set up processing fees for credit card payments.

  • Choose the percentage fee for different card types, including Visa, Mastercard, and American Express.

  • Link processing fees to a Billing Plan to track revenue correctly.

  • Apply fees automatically to unpaid invoices once credit card details are added.

  • Understand how partial payments and alternative payment methods affect processing fees.

  • Turn off processing fees when needed and see how the system handles existing invoices.


Before you start

Important: Merchants can apply surcharges where permitted by federal and state laws. However, before charging fees, clear customer notification, such as prominent signage or explicit terms in agreements, is required.

When and why to use processing fees?

If you want to recover the transaction costs charged by credit card providers without manual adjustments, processing fees help you do this automatically. You may use this feature if your space processes numerous credit card payments and you want to avoid hidden costs that could impact your finances.

What you can achieve

With processing fees, you can set automatic charges for credit card payments to cover transaction costs without manual work.

You can:

  • Define a default fee and custom fees for Visa, Mastercard, and American Express.

  • Link fees to a specific Billing Plan so they are tracked under the correct revenue account.

  • Apply fees to all unpaid invoices when card details are added, ensuring no manual edits are needed.

For example, if a member adds a credit card after an invoice has been issued, the system will adjust the invoice to reflect the correct fee. If a member pays part of an invoice with a card and the rest with another method, only the card portion will include a fee based on the first payment method.

Processing fees do not apply to payments made by bank transfer, check, PayPal, or through hosted gateways. The system removes any card fee if a non-card method is chosen.
