A default agreement is one that ISN sends out if no agreement association has been made under the 'Associate Agreements and Inspection Types' page.
Setting your default agreement in ISN is a simple process that takes little to no time at all!
Go to Settings -- Office settings -- Inspection and Fee Settings -- Agreements
Once on the agreements page, click on the DEFAULT button/column of the agreement that is to be your default.
NOTE: The agreement marked as the default is the agreement sent out for all inspection types unless otherwise specified in Associate Agreements and Inspection Types
