While the built-in record types cover things that every team has in common, you most likely need to keep track of data that is specific to your team and industry.
In these situations, you can easily create your own record types.
If you’re a transportation company, your conversations may refer to physical trucks, planes, and ships in the real world.
You can link contacts to records for your products, services, licenses, and subscriptions. During support, everyone on your team will know exactly what your relationship is with each contact.
An educational institution can create records for students, instructors, courses, and rooms. Those records can then be linked to assets (like tablets and projectors) and support requests. If an instructor opened a support request about their projector being broken, you’d know exactly what model it is and where to find it on campus.
