TWF is an NGO that among other things organizes many in person events during the year, including a big conference that attracts up to 10,000 visitors.
They connect with many vendors to fulfill on these events, including catering, decoration, stationery, photography, PR, marketing, equipment rental supplies and freelancers, among others.
They were reluctant of giving Salesforce access to all of them as it would concur in increased costs, time spent on training, and IT security protocols to follow.
