Frequently asked questions
Jonas Club Software scores F on the API Report Card. No open, self-serve API. Integrations route through Jonas ARC, an integration platform exposed only to vetted partners under signed agreements; there is no public documentation or key signup. Clubs can fall back to ODBC and Crystal Reports exports.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Jonas Club Software is an integrated management suite for private clubs, covering club accounting, member billing, POS (F&B and pro shop), tee-sheet and reservations, banquets/events, inventory, payroll, document management, member CRM, websites and a member mobile app (ClubHouse Online).
Vertical: POS / Hospitality (private-club management). Club staff use Jonas daily for: ringing F&B and pro-shop sales on fixed and mobile POS; running tee-sheet, court, dining and spa reservations; managing member rosters, dues, statements, minimums and AR; processing banquet event orders/BEOs; tracking inventory and purchase orders; running club accounting (GL, AP, bank reconciliation) and payroll; producing financial and member reports; and pushing email/SMS marketing campaigns.
High within its niche, low overall. Jonas Club Software is one of the two dominant private-club platforms in North America (the other being Clubessential Holdings) and is heavily entrenched at high-end Distinguished/Platinum clubs.
Member profiles (PII, household relationships, membership class/status, dues schedules, sponsor links). Account ledgers, statements, minimums, dues billing and AR aging. POS transactions (F&B and retail), tabs, gratuities and tax.
Founded September 1990; ~35 years old. The core Jonas Club product is a long-lived Windows/.NET + SQL Server stack with web and mobile front-ends (ClubHouse Online, Mobile POS, GM App, Kitchen Display) layered on top.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Jonas Club Software API and MCP server so AI agents and internal tools can read and write Jonas Club Software data. See the Jonas Club Software integration docs at supergood.ai/docs/jonas-club-software-api.
