You can set the checkout period, between 1 and 21 days, using the administrator tools.
First, log into your MackinVIA Administrator account (https://www.mackinvia.com/Admin) with your Mackin.com email address and password.
Choose Settings > Checkouts/Requests (make sure you select the correct VIA if there is more than one account).
Make sure the button next to Checkouts reads Enabled. (If the button reads Disabled, click to enable.) Enter the desired number of checkout days in the Loan Period box under Checkouts (you can choose up to 21 days).
Click Save Changes when you’re finished.
