Should trusts be categorized as companies?

Answer

Yes

Context

For the vast majority of Nonprofit use cases, constituents are always customer records in NetSuite. Contacts are almost never used. NetSuite allows you to classify a customer record as a company or individual.

Constituents who are individuals should always be entered as individual customers.

Any other type of constituent (corporation, foundation, household, trust, donor advised fund, etc.) should be entered as a company.
