Memberships expire quietly
Expired members keep using the facility because nothing prompts a renewal conversation.
Products
EH Gym ERP
Memberships, subscriptions, attendance, point of sale, finance and reporting for gyms and clubs.
Gym Management PlatformDevelopment / pilot preparation
Product overview
- Built around the reception desk, where membership validity has to be answered in seconds.
- Subscription validity is calculated from the plan, start date, freeze periods and cancellations rather than a status flag someone must remember to update.
- Point of sale, payments and finance records attach to the member and the subscription they settle.
- In development and preparing for pilot use — not presented as a deployed commercial installation.
Intended users
- Reception staff handling check-in and renewals
- Membership administrators managing plans and pricing
- Trainers viewing class rosters and attendance
- Owners reviewing renewals, collections and attendance patterns
Business problems addressed
Slow validity checks
Staff open several files to answer whether a membership is still valid.
Untracked collections
Outstanding balances and daily takings are reconstructed manually after the shift.
Core capabilities
Membership and subscriptions
Plans, renewals, freezes and cancellations with calculated expiry dates.
Attendance and check-in
Fast member lookup with a clear valid or expired state and a timestamped log.
Point of sale and finance
Counter sales, receipts, outstanding balances and daily collection reporting.

- Member identification treated as personal data with restricted visibility

Deployment model
Hosted or on-premises web deployment
Intended for a club-hosted or cloud-hosted deployment with documented environment configuration, database migrations and backup expectations. Reception workflows are designed for reliable local operation once the site is online.
- Separate staging and production environments
- Migration-driven schema updates
- Documented backup and restore procedure
Known scope boundaries
- In development and preparing for pilot — module availability is confirmed per engagement
- Not a multi-branch franchise platform unless separately scoped
- Access-control hardware integrations scoped per deployment
- Statutory accounting remains a separate scope decision
Frequently asked questions
It is a web platform. Reception and administration require connectivity to the hosted environment. Offline-first desktop operation is not part of the current scope.
