Configure credit card surcharge rules in Maxio Payments by country, state, and card brand. Customize checkout disclosure language, review surcharge setting changes, and use interchange and scheme fee averages to support surcharge rate decisions.
You can customize how surcharges are applied:
Surcharge amounts are included in the invoice total that syncs to your connected accounting integration (NetSuite, QuickBooks, Xero, Intacct, or Rillet). Contact Maxio Support if you need surcharge amounts broken out as their own line item in your general ledger.
After surcharging is enabled, you can manage your configuration directly in Maxio Payments.
To manage your surcharge configuration
If the country-level toggle is off, surcharging is deactivated.

Each card brand's rate, at both the country and state level, has a maximum of 4%.
Use state-level settings to control where surcharges apply:

Customize the disclosure language shown to buyers during checkout.

Review all edits to surcharge settings in the changelog section.

Important: Interchange and scheme fee averages are informational only. You are responsible for ensuring your surcharge configuration complies with applicable laws, card network rules, and processor requirements. Maxio recommends consulting legal counsel before applying or changing surcharge rates.
For each state or U.S. territory, Maxio Payments shows an estimated average cost of credit card acceptance next to each card brand's rate field. Use these estimates to help inform surcharge rates based on your business requirements and applicable regional regulations. This average is not available at the country level, only for individual states and territories.
Maxio Payments calculates a trailing 90-day average of interchange and scheme fees for each supported card brand and jurisdiction. These estimates are refreshed daily.
If there is not enough transaction data for a specific card brand in a jurisdiction, the field shows Calculating… until enough data is available.
Interchange and scheme fee averages appear alongside each card brand's rate field on the Surcharge Settings page.
To view interchange and scheme fee averages
You can exclude specific product families from surcharging entirely, using settings in both Maxio Payments and Advanced Billing.
To exempt a product family from surcharging
Subscriptions in that product family are never surcharged, even if the buyer's billing address and payment method would otherwise be eligible.
