OSS
TIME
Time to take control of your club.
No more paper and spreadsheets. OSS Time handles the admin around your club — so you can focus on training.
First month free · No commitment · Onboarding included
No more paperwork. No more spreadsheets.
Club admin eats up more of your time than training itself. OSS Time takes it off your hands — so you can focus on your members.
Who is OSS Time?
Martial arts clubs
Club management software — judo, BJJ, karate, boxing, taekwondo and other martial arts. Complete club management in one place.
Sections and branches
Running a club in several places? Member records, lesson schedules and attendance for each gym and section separately.
Coaches
Scan attendance from your phone, check payments and manage members — right from training.
Club management
Statistics, payment overviews, coach management and online registration of new members. Keep your club under control.
Everything to run your club. In one place.
From new member registration through attendance and payments to statistics and accounting export. Click a feature and explore it in detail.
Attendance records itself
No more paper sheets and copying into spreadsheets. Just scan a membership card — OSS Time records attendance, deducts an entry and shows membership status right away.
- Scan a barcode = attendance done
- Instant payment status — green, amber, red
- Automatic entry deduction
- No paper, no manual rewriting
Members under control
Complete records in one place — contacts, programs, payments, attendance and belts. Filter by branch, program or membership status. Search without diacritics.
- Color-coded statuses — see at a glance who's paid
- Visual display of belts and gradings
- Family and group memberships
- Detail with full attendance and payment history
New member registration online
Share a public registration link or QR code. A new member fills in the form, accepts the terms and appears in your records right away — and instantly receives a confirmation email with payment details.
- Confirmation email with a QR code to pay the fee
- GDPR and terms consent
- Automatic payment reference number
- New member straight into records, no rewriting
Show this QR code to a prospective member — they scan it with their phone and open the registration form.
Payments under control
To record a payment just enter a name or payment reference — we handle the rest. OSS Time recognizes family and group payments by itself, sends a payment receipt and tracks unpaid memberships and used-up entries.
- Enter a group or family payment with a single form
- Payment receipt emailed to the member
- Notifications for unpaid memberships and used-up entries — with a QR code to pay
- Entry-based and time-based memberships and family plans
- Export payments to accounting (Pohoda)
Program: Parent + Child, siblings… (3,750 CZK)
See how your club lives
No manual spreadsheets. Attendance and utilization charts calculate themselves — who attends, which day is busiest and how full individual lessons and gyms are.
- Attendance by students, lessons and branches
- Utilization of individual lessons and gyms
- Busiest days of the week
- Date range selection and data sorting
Attendance statistics
Belts made clear
No more guessing who got which belt and when. Set up a belt system to match your association and see each member's current belt and full progression history.
- Custom belt system tailored to your club
- See the current belt and progression for each member
- Date awarded and a custom note for each belt
- For judo, BJJ, karate, boxing and other martial arts
And that's not all
Multiple branches
Manage several gyms and sections from one place — each with its own lessons, schedule and statistics.

What we're building
OSS Time keeps evolving. Here's what we're working on right now.
Student portal
A self-service portal where every member sees their schedule, attendance, payments and membership status.
Event registration
Seminars, camps, competitions — members sign up with a single click.
Accounting exports
Beyond the Pohoda export, we're building integrations with more accounting systems — even custom ones for your club's needs.
