Can installers reschedule their appointments less than 6 hours in a single day?

No. ReadiCharge values the customer's convenience. Remember, Basic Installation service is estimated to take up to 6 hours (with travel time), so to ensure an installer is able to complete the installation in one visit, ReadiCharge requires them to be available for at least 6 hours in a day. 

Additionally, some service tiers, or multiple charger installations, may take unto 12 hours so an installer's availability needs to accommodate the services they selected to offer. (Go to your App Settings to edit your service offerings.) Please follow this LINK for more information on rescheduling.

Please note: Missed/cancelled appointments negatively affect your rating and your ability to get future jobs via ReadiCharge.
