Gyms and fitness studios rarely fail on ERPNext because it can't invoice — they fail because the day-to-day objects a gym actually manages don't exist in ERPNext core. There is no Membership Plan, no Class Schedule, no trainer roster, no turnstile check-in, and no clean way to bill a member every month and chase the ones whose card declined. Teams end up bolting Subscription onto a Customer, tracking classes in a spreadsheet, and calculating trainer pay by hand — a stack that breaks the moment you add a second location or a second membership tier. This is where ERPNext native runs out of road for a fitness business.

ECOSIRE builds a proper Frappe app — installed into your own ERPNext bench — that models your operation as first-class DocTypes: Membership Plan, Member, Membership (with start/end, freeze and renewal state), Class Session, Class Booking, Trainer, and Attendance Log. Each connects to the ERPNext modules you already trust: a renewal issues a real Sales Invoice, recurring billing rides on ERPNext Subscription, and trainer commissions post through Journal Entries so your books stay reconciled. We keep everything inside standard ERPNext rather than a disconnected side system.

The behaviour is wired with hooks.py doc events and server scripts — validating class capacity on booking, generating the next invoice on renewal via a doc_events handler, and flagging overdue members through a scheduler_events cron for dunning — rather than fragile manual steps. Client scripts drive the front-desk UX (barcode/QR check-in, one-click renewal, freeze/unfreeze), while whitelisted methods exposed over the Frappe REST API let a mobile app or turnstile controller book a class, log attendance, or read a member's status. Role Profiles and permission rules scope what the front desk, trainers, and accountants can each see, and reports run on native Query/Script Reports so your data never leaves ERPNext.

Because this is build-to-order, we start from your real plans, class formats and commission rules — not a generic template. After a scoping call we deliver a written scope, build on ERPNext v15/v16, and stage it for you to test. Typical delivery is one working week from confirmed scope depending on how many plan types, locations and integrations you need. You receive the installable source, a git repository handover, and a post-go-live support window — you own the app and can extend it yourself or keep us on to evolve it.
