Card Fees and the Margin Hiding in Your Invoices

Card processing is priced as a percentage, which means the cost is invisible on a small invoice and substantial on a large one. Most businesses set the payment options once, at the small-invoice stage, and never revisit them.

On a $9,000 invoice, the difference between card and bank transfer is roughly the cost of a month on a plan. Not once — on that invoice, and on every comparable invoice after it.

The Change

This is not about removing card payment. Card is convenient, clients expect it, and for small amounts the fee is genuinely not worth managing.

• Set bank transfer as the default option on invoices above a threshold you choose.
• Keep card available as a second option for anyone who prefers it.
• Do not add a surcharge without checking the rules in your state and with your processor.
• Say nothing about fees on the invoice. The default does the work; an explanation invites a negotiation.

Why Defaults Carry It

Most clients pay by whatever method the invoice presents first. This is not manipulation — both options are there and both are clearly labeled. It is simply that a default is a decision somebody has already made for you, and most people accept it when the alternative is equivalent.

Where It Fits

This is a stack-build change and one of the few in the entire method that pays back immediately and permanently, with no behavior change required from anyone in the business. It takes about ten minutes in most platforms.
