Universal Containers sells capital equipment that includes a 90-day warranty for repairs.

Establish a new customer on-boarding administration role and have that Service Resource manually create the 'Asset' records and create custom checkbox fields to determine if the 'Asset' is under 'Warranty' and signed up for the 'Preventative Maintenance Service Contract'

Create a custom object called 'Capital Equipment' and create these records from 'Opportunity Products' when an 'Opportunity' is 'Won'. That record will have a formula checkbox field if it is under 'Warranty'. Create a 'Maintenance Plan' record if the customer signs up for a 'Preventative Maintenance Service Contract'

Use 'Opportunity Products' that will create 'Assets' when the 'Opportunity' is 'Won' with automation. That automation can also create a 'Warranty' record for the 90 day period. If a 'Preventative Maintenance Service Contract' is purchased, have an automation to create a 'Service Contract' record, 'Maintenance Plan' record, and 'Maintenance Asset' records

Set the 'Warranty' and 'Maintenance Plan' as related lists on the 'Account' Record. Create an Automation that will trigger the creation of 'Preventive Maintenance Service Appointments' based on the related 'Maintenance Plan' if a 'Warranty' record is added as well
