This article shows how to activate a checkbox on your donation form and event pages allowing the donor and/or event attendee to cover the merchant gateway transaction fee.  It also shows how to set the percentage in your database that they’ll be covering (which varies from gateway-to-gateway). Click this link to view all the merchant gateway options that Trail Blazer integrates with.

Steps to Set the Merchant Gateway Transaction Percentage (%) and Activate it for your Donation Form

Open Website ConfigurationRequires security clearance.

Under the Site Settings tab set the percentage (%) you want your donors and/or event attendees to *optionally cover, and then click [Save]In my example I set the percentage to 3% which covers the 2.75 percent my merchant gateway takes + the .45¢ per transaction.

Navigate to the Donations tab, check the box for ‘Include Merchant Fee Pay Option’, click [Save] and then click the blue hyperlink in the top-right for ‘Click here to refresh your web pages using updated specifications’.

Click [OK] to proceed with the web page refresh.

You’ll be prompted once the refresh is complete.  Click [OK] to finish.

You’ll now be able to view the new option on your donation formIn this example I viewed the form where it’s hosted on Trail Blazer’s secure domain e.g.

If the donor opts to cover merchant gateway fee they’ll receive an email receipt showing the full amount that was charged.  My example is below.

In the database you can build reports that include this data in the Contributions list.

Navigate to Contributions under the Application Menu.

Click the [Format] drop-down and select Columns…

Check the box for ‘AmountDonorOptedGatewayFee’ and click [OK].

The new column will display in the grid (by default it will be added to the far right).

If the merchant gateway fee was covered for the online transaction it will display in the cell.  You can drag the columns left-or-right to rearrange them – my example is below.

You can save this format for future use.





Steps to Add the Option for Event Attendees to Cover the Transaction Fee on an Event
