Rezdy is a booking and distribution platform built around reselling activities through agents and a B2B marketplace. Social Good Software runs cultural admissions and membership on Blackbaud Altru. The difference is the channel: Rezdy sells through resellers; a museum sells to its own members and donors.
A reseller channel vs a direct member relationship
Rezdy’s strength is distribution: pushing tours and activities out to online travel agents and reseller networks. A cultural nonprofit works the other way, deepening a direct relationship with members and donors over years. Rezdy is not built for membership tiers, renewals, or a donor record, because that is not the job it does.
When Rezdy is the right call
For a tour or activity operator that wants to distribute inventory through agents and a reseller marketplace, Rezdy is a capable, purpose-built channel platform.
A direct relationship, on Altru
Social Good Software runs admission, membership, and donations directly on Altru, so every sale strengthens your own constituent record rather than a reseller’s.

You sell direct, not through resellers, if…
A distribution platform optimizes the channel; a cultural nonprofit needs the direct relationship.
