One Group Central - 2026 Pricing, Features, Reviews & Alternatives

One Group Central is a private, invite-only member portal for organizations that make decisions together: homeowner associations, labor union locals, county professional societies, membership nonprofits, and cooperatives.

Everything members need lives in one branded app. Admins publish documents, send announcements that reach members by email, SMS, and push notification, run polls and elections, manage an event calendar with RSVPs, and organize members into groups. Members get realtime chat with channels and direct messages, a searchable member directory, and their organization's files in their pocket.

The standout feature is voting members can trust. Ballots are encrypted and cryptographically anonymous: no administrator, board member, or even One Group Central staff can see how an individual voted. Every ballot is recorded on a tamper evident hash chain, and every voter receives a receipt they can independently verify. One person, one vote is enforced in code, not by policy.

Setup takes minutes, not migrations. Invite members by CSV, brand the portal with your logo and colors, and turn off any feature you do not need. Sensitive files can be stored in an encrypted document vault, and scanned PDFs become searchable automatically.

Pricing is a flat monthly fee for the whole organization: $49 for up to 100 members, $99 for 300, $149 for 500, and $199 for 1,000. Every plan includes every feature, there is no setup fee, and the 60 day free trial requires no credit card.

One Group Central runs on the web, iOS, Android, macOS, Windows, and Linux, and is built and supported in New York by NJLIGames Ltd.
