Everything is connected
One person, one family, one club, one source of truth. Payment, session, attendance, evaluation and certificate are tied to the same activity, so every screen links through to every other screen.
The membership platform for sports clubs in Belgium
Less admin. More sport.
One platform for the board, coaches, parents and athletes. Membership fees, registrations, calendar, attendance and development, connected in one club.
- Everything connected: one person, one family, one source of truth
- The platform thinks ahead: signals with the action attached
- Belgian practice built in: certificates, UiTPAS, direct debit, federations

The problem
A club runs on volunteers doing evening admin in five separate systems
That costs members, money and coaches.
- The secretary tracks membership fees in Excel and the banking app, makes certificates one by one and redoes the season rollover every summer.
- The treasurer matches bank transfers without a reference and only finds out in November who hasn't paid.
- The coach takes attendance on paper or in a WhatsApp group and doesn't know who is injured or who hasn't paid yet.
- The parent has a different account for every club and every child, and no overview of what is still outstanding.
- The athlete gets one evaluation a year, without a voice of their own and without a trend.
- The club doesn't see a member drifting away. The membership fee that stops coming in is the first signal.
The solution
One platform, three promises
Membrix replaces the separate systems with one connected whole that thinks ahead with you.
The platform thinks ahead
Membrix tells you what needs attention. A member drifting away, a membership fee falling due, a child ready for the next level. Every signal comes with the action attached.
Belgian practice is built in
Health insurance fund certificate, tax certificate 281.86, UiTPAS reduced rate, structured communication (OGM) with CODA import, SEPA direct debit, federation affiliations and the criminal record extract for coaches. As standard, with no plug-ins.
Signals
A member list records what happened. Membrix tells you what needs to happen now.
Attendance, payments and evaluations live in one connected whole. So Membrix sees links you miss in separate lists, and prepares the next step.

The rules built in, and you can prove it
A club that works with children has had a series of Flemish and Belgian obligations since 2023. Membrix builds them in as product rules.
- Criminal record extract for coaches and volunteers, with expiry date and reminder
- Own login from age 13, below that the parent acts on the child's behalf
- Both parents get the same information, even after a separation
- Tax certificate 281.86 and the Belcotax file in one click
- Medical form visible only to the supervisors of that activity
