# How do I include the credit card fee in my invoices?

The credit card processing fee can be included in your invoices by increasing your prices a percentage slightly more than your credit card fee. Or use this formula to raise your prices the exact amount of the fee:

```
(price + fixed) / (1 - rate)
```

where *price* is the original price, *fixed* is the fixed component of the fee (ie. 0.3), and *rate* is the percent component of the fee (ie. 0.034).

If your agreement or contract with your customers allows you might be able to add the fee as a separate line item on the invoice so long as it applies to all payment methods equally.

Then set a discount equal to the price increase to offer your customers the original price for ACH payments. Visit the [My Account](https://www.receivabl.es/account) page, enable the checkbox 'Discount ACH payments', and enter the discount rate.

This is the preferred practice for recovering credit card processing fees and is actually [protected by legislation](http://www.ncsl.org/research/financial-services-and-commerce/credit-or-debit-card-surcharges-statutes.aspx) in 10 U.S. states: California, Colorado, Connecticut, Maryland, Massachusetts, Nevada, Oklahoma, Washington, Wisconsin and Wyoming.
