Beginning January 1, 2026, Assembly Software will apply a 3% credit card convenience/surcharge fee (maximum % in your state, if lower than 3%) to invoices or accounts paid by credit card.
To avoid this surcharge, we encourage all customers to transition to ACH payments (preferred) before the end of 2025. ACH transfers can be scheduled directly through our Customer Portal (see link below) or initiated by your finance team through your preferred bank.
Payment Options:
ACH (Preferred): Schedule recurring transfers through the Customer Portal (free/no-fee option) or via your bank.
Check: Mail checks to the address below.
Credit Card: Pay via the Customer Portal. A surcharge will be applied in accordance with your billing address's state regulations.
The convenience fee amount will comply with state laws, credit card brand guidelines, and will not exceed Assembly's actual processing costs.
NOTE: Customers in the following states will not be charged, as state law prohibits this fee for using a credit card: CA, CT, KS, MA, ME, and MN.
NOTE: Customers in CO will only be charged/assessed 2%, as this is the maximum % set by the state of Colorado.
Important Reminders:
ACH Payments: Up to $200,000 can be paid through the portal; payments exceeding this amount must be initiated by your bank or sent via check.
Monthly or Quarterly Payers: Must pay using ACH or credit card payments.
Deadline: Please set up your ACH payment method by December 31, 2025, via our GoCardLess app in the Customer Portal to avoid the convenience fee.
