Guided sell flow
Pick a plan, apply a coupon, choose a payment method. Tax and totals recompute live as you go, so the number on screen is the number on the invoice.
GST and sales-tax invoices
Numbered, audit-friendly invoices generated the moment you take payment. GST inclusive for India, sales tax added on top for the US.
Automated renewal reminders
Reminders go out before a membership expires over WhatsApp, SMS, or email, with a one-tap nudge whenever you want to chase sooner.
Collections and dues you can act on
See exactly who owes what and how long it has been outstanding, then collect with a reminder or record a payment on the spot.

The two artifacts your members actually see. A WhatsApp nudge lands before the plan expires, and the moment they pay, a numbered tax invoice is ready: CGST/SGST split, SAC code and all.

This is the rhythm of a working gym. GymOS makes each step take seconds and carries the data forward, so the loop closes on its own.

Issue an invoice
A numbered, tax-compliant invoice is generated and saved against the member, ready to send.

GymOS schedules a reminder before the plan expires and lets you nudge over WhatsApp, SMS, or email.

Watch the dashboard
Every sale and cost flows into net profit per branch, so you always know where the business stands.
The reminder pulls them back. The loop keeps running.
Every renewal lands as revenue, every cost lands against it, and the dashboard keeps score in real time.
We read the reviews of the big platforms, then built the opposite.
Across hundreds of owner reviews of incumbent gym software, the same four complaints kept repeating. Each one is a design decision in GymOS.
0% commission, permanently
Payments stay at your desk: cash, UPI, card, bank, recorded in seconds. GymOS never takes a cut of member payments.
logged complaint: “My software takes a cut of every member payment.”
Your data exports anytime
Members, payments, invoices, and expenses export to CSV whenever you want. No tickets, no retention calls.
logged complaint: “Leaving means losing years of member data.”
The quoted price is the bill
Flat monthly tiers in your own currency, taxes stated upfront, no setup fees, no annual lock-in. Cancel or switch anytime.
logged complaint: “The price I was quoted is never the price I am billed.”
A sell flow staff actually use
One dialog the front desk finishes in seconds, with tax and totals recomputing live. Software people avoid produces numbers you cannot trust.
logged complaint: “My staff hate the software, so nothing gets recorded.”

The questions owners ask first.
Do members pay through GymOS?
Today you record payments taken at your desk — cash, UPI, card, or bank — with zero commission, and GymOS issues the invoice instantly. UPI and card payment links that ride on the renewal reminders are next on the roadmap, so a member can pay straight from the message.
How do the WhatsApp reminders work?
You write the message once per channel — WhatsApp, SMS, and email each get their own template with variables like the member name and expiry date — and pick the touchpoints, for example 7 days and 1 day before expiry. Routine renewal reminders are included in your plan rather than metered per message.
Is my data locked in?
No. Members, payments, invoices, and expenses export to CSV whenever you want, and every invoice is downloadable as a PDF you keep. If GymOS stops earning your business, leaving is easy — that is deliberate.
Does it handle GST correctly?
Yes. GST-inclusive pricing with the CGST/SGST split shown on every invoice, your GSTIN and SAC code printed, and sequential duplicate-proof invoice numbers per branch. In the US, sales tax is added on top of the listed price and itemized.
What about multiple branches?
Each branch keeps its own plans, pricing, tax profile, and team. The dashboard rolls everything up to one net-profit number, and teammates you invite can be scoped to a single branch — they see only what they run.
Do I need new hardware?
No. GymOS runs in the browser on whatever is already at your front desk — a laptop, a tablet, or a phone.
Leave the spreadsheet. Run the gym.
NIGHT 21:45. Doors locked, numbers in.
