The rates and fees associated with processing credit cards are primarily determined by the risk associated with running the transaction. Because we work with so many Home Inspectors, we have been able to create an account that gives the lowest rates to transactions that have historically been charged at a higher risk level. We try our very best to make sure our pricing is as simple as possible to understand.

*The monthly minimum is made up of your processing fees. Using the average home inspection transaction of $400, you would only need to do about 4 transactions a month to cover the minimum.

**We waive the PCI Compliance fee for the first 12 month of the account. We also have the lowest compliance fee in the industry compared to the average of over $149 annually.
