Ecosystem

4b2b Ecosystem · Romania

Your gym, run with 4gym and connected to the entire 4b2b ecosystem

4gym runs your gym, sports club or studio — memberships and member access, group class scheduling, trainers and personal-training sessions, door access control — and connects it, through the 4b2b ecosystem, to the products you need: membership invoicing, accounting, member reminders over SMS and WhatsApp, CRM and hosting. One account, shared data, no manual integrations and no re-entry.

Key integrations · around the gym you run with 4gym

The gym you run with 4gym connects via API to the separate products in the 4b2b ecosystem. Each integration runs on the same account, with data synced automatically — no manual export, no re-entry.

Invoicing connected to your gym

4invoices.net

Memberships and session packs sold at the front desk become receipts and invoices automatically

A separate invoicing product in the 4b2b ecosystem that the gym you run with 4gym connects to via API. A membership activated or renewed at the front desk automatically triggers receipt or invoice issuing in the invoicing product — no manual export, no re-entry.

What you connect
  • Membership → receipt / invoice automatically

    Every membership sold or renewed in the gym run with 4gym reaches the invoicing product and generates the matching document, with member data pulled from the record.

  • Sync via API

    Membership types, prices and members stay aligned between the gym and the invoicing system over API, with no double maintenance.

  • Connected payments

    A card payment for a membership or session pack automatically marks the document as paid in the invoicing product, through the ecosystem's payments integration.

  • One 4b2b account

    Turn on invoicing on the same account you run the gym with — no separate provider, no re-onboarding.

Digital contracts connected

4mycontracts.net

Membership agreements and trainer contracts, generated from your gym data

A separate contract-management product in the 4b2b ecosystem. Membership agreements, data-processing agreements, health declarations or contracts with freelance trainers are generated with data pulled automatically from the gym you run with 4gym and sent out for electronic signature.

What you connect
  • Generated from gym data

    Member and trainer data from the gym automatically populates the document in the contracts product, with no re-entry.

  • Signing and tracking

    Documents are signed on a tablet at the front desk or on the member's phone, and their status flows back into the shared 4b2b account panel.

  • Connected via API

    The gym and the contracts product exchange data over API, with no manual integrations.

  • On the same 4b2b account

    Turn on contracts on the account you run the gym with — no separate provider.

Member reminders

4notify.net

SMS, WhatsApp and email triggered by gym events

A separate notifications product in the 4b2b ecosystem. Events in the gym you run with 4gym — a confirmed class booking, a membership about to expire, a waitlist spot that just opened — can automatically trigger messages over SMS, WhatsApp and email, with no integration code to write.

What you connect
  • Triggered by gym events

    Class booking confirmed, membership close to expiry or a waitlist spot released — every step automatically starts the member message, through the gym's connection to the notifications product.

  • SMS + WhatsApp + email

    Booking confirmations and no-show reminders for capacity-limited classes across multiple channels, managed from one place on the 4b2b account.

  • Connected via API and webhooks

    The gym talks to the notifications product over API and webhooks, with no manual integrations.

  • GDPR-friendly

    Consent and opt-out handling stay in the notifications product, connected to the member data in the gym.

Human resources for your gym team

4softhr.net

From the front desk to every trainer's file

A separate human-resources product in the 4b2b ecosystem. The gym team you run with 4gym — trainers, group class instructors, front desk — is managed in the HR product: files, timekeeping, shifts and onboarding, on the same account, with no re-entry.

What you connect
  • Your gym team, organized

    Trainers, group class instructors and front-desk staff get files, contracts and timekeeping in the HR product, with no parallel spreadsheets.

    Plan front-desk shifts and instructor rosters across studios and training floors directly in the HR product connected to the shared 4b2b account.

  • Connected via API

    The gym and the HR product exchange data over API, with no hand-written integrations.

  • On the same 4b2b account

    Turn on HR on the account you run the gym with — no separate provider, no re-onboarding.

Online bookings connected

4Appointments.net

Group classes, personal-training sessions and fitness assessments, booked online 24/7

A separate bookings product in the 4b2b ecosystem. The booking widget mounts directly on the website of the gym you run with 4gym — for group classes, personal-training sessions or fitness assessments — and every new booking flows on to the member record, reminders and invoicing.

What you connect
  • Booking widget on the site

    Members pick their class and slot right on the website of the gym run with 4gym, without leaving the page.

  • Reminders via notifications

    Confirmations and reminders go out through the connected notifications product so seats in capacity-limited classes don't go empty.

AI summary

4gym advantages in the 4b2b ecosystem

  • Run your gym — memberships and member access, group classes, trainers and personal-training sessions, door access control — and connect invoicing, accounting, CRM and reminders in the same account, with no manual integrations.
  • Shared data: a membership sold or renewed at the front desk automatically generates the receipt or invoice and lands in the CRM, with no re-entry.
  • Member reminders via SMS and WhatsApp, triggered automatically by gym events (class booking, membership about to expire, waitlist spot released).
  • Hosting included on EU infrastructure, with SSL and CDN, no separate provider.
  • Gym management: class timetable with limited spots and a waitlist, member card with membership and attendance history, trainer commissions and a recurring-revenue report, from a single account.
  • Single sign-on and one panel for the whole ecosystem — including the presentation site built with 4buildsite, the sister brand.

Cons

We are transparent — here is where 4gym is not yet the best fit:

  • Not an enterprise platform for international fitness-club chains with a dedicated SLA and highly complex workflows.
  • No native integration with every international multi-club membership aggregator on the market.
  • Turnstiles and card/QR readers connect over API — older hardware without a network interface needs the team, not just panel settings.
  • The connected business products are tuned for the Romanian market — less relevant outside RO.

Short verdict

Choose 4gym when you want one place to run your gym and manage the business — memberships, group classes, trainers and access control plus invoicing, accounting and CRM in the same account. If you only need a standalone class-booking app with no connected back office, a classic application may be enough.
