The Inspection Support Network has established a valuable partnership with Guardian Services to cater to your credit card processing needs. The following article will walk you through the process to set up Credit Card Processing. You'll need to get a Guardian account and then you'll want to connect it to your ISN.

The steps for both of these processes are outlined below:

1. Getting a Guardian Account

First, you need to ensure you have an account with Guardian Financial. They offer the most competitive rates in the inspection industry, have no monthly fees, and are the sole officially supported Credit Card Processor for ISN. If you don't have a Guardian account yet, reach out to them today to discuss making the switch!

2. Finding Merchant ID, User ID, and Password

  • Your User ID and Password will be the same ones you use to log into your account.

  • To locate your Merchant ID, log in to your Cardpointe account and navigate to Administration β†’ Descriptors β†’ Location, then identify the numbers prefixed by MID.

3. Connecting Your ISN and Guardian Accounts

  • Initiate the process by navigating to the "Settings" menu.

  • Within the "Settings" menu, specifically, locate and select "Office Settings."

  • Once you are in the "Office Settings" section, please identify the subsection titled "My Office Settings."

  • Within this subsection, proceed to locate and click on the option labeled "Payment Options."

Path: Settings > Office Settings > My Office Settings > Payment Options

  • Check the box for 'Use the ISN Payment System' if it's not already selected.

  • Choose Guardian Financial in the Card Payment System section.

  • Enter your Guardian Financial account's Merchant ID, User ID, and Password.

  • Click 'Save Payment Preferences' to complete the setup.

4. Enable Credit Card Authorization

  • At the bottom of this page, select whether or not you want to use Credit Card Authorization, and don't forget to click Save Payment Preferences.

We strongly advise against using Credit Card Authorization since inspection prices can change once an inspector is on-site. Once a card has been authorized, the authorized amount cannot be modified, necessitating a new charge.

Congratulations, you've successfully configured Credit Card Processing within ISN. Happy inspecting!
