An example embodiment includes a system server configured for social network-based inventory management. The system server includes processors and non-transitory computer-readable storage media communicatively coupled to the processors. The media store instructions that, in response to execution by the processors, cause the processors to perform operations. The operations include receiving category specifications and access category definitions for access categories. The access category definitions include relationship criteria for the access categories. The operations include identifying a relationship between a second user and a first user, comparing an identified relationship with the relationship criteria, and determining which of the access categories the second user is included based on the comparison.
