Cost reality

Hosted free tier historically offered; self-host available. Verify current pricing and license.

Pricing and free-tier limits change frequently; re-check official pricing before budget decisions.

Official pricing

Tasks reduced or augmented

Software does not replace community or ops staff. It may reduce or augment:

Recurring membership invoices
Client portal for PDFs

Human oversight still needed

License verification
Tax configuration
Payment reconciliation

Manual process this can replace

Structured task-fit review has not been completed for this tool. Treat the free-text examples above as evaluation prompts, not replacement claims.

Risks

Area	Notes
Vendor lock-in	Evaluate export formats and API completeness before deep customization.
Security	Apply updates promptly; restrict admin access; enable TLS.
Compliance	Operator remains responsible for privacy and local regulatory obligations.
Licensing	License has changed over versions; verify the version you deploy. Do not assume OSI open source without checking.
Operational	Plan backups, monitoring, and a restore drill before production use.

Coworking fit

Roles: finance, owner-operator, operations-manager
