SwimFlow is a complete management platform built for sports clubs. It started as a solution for swimming clubs and grew into a multi-sport system that lets a single organization run several disciplines side by side — each with its own venues, schedules, and public sign-up page. Members register online in a few minutes, pay the way that suits them, and get a scannable membership badge; staff manage everything — members, subscriptions, payments, attendance, and even a club shop — from one dashboard. The whole experience is fully multilingual (French, Arabic, and English), making it a natural fit for clubs and their members.

• Fast, guided online registration with document upload.
• Multiple payment options — online payment, bank transfer, or cash at the club.
• Personal, scannable membership badge.
• Public pages for club activities, news, services, and contact.
• Member management with subscriptions, renewals, and status tracking.
• Multi-sport support — run several disciplines, each with its own venues, schedules, and pricing.
• Payment tracking and validation across all payment methods.
• Attendance / check-in with badge scanning at the door.
• Membership badge printing.

Before — Algerian hotel owners were stuck between two bad options: run operations on disconnected tools — spreadsheets for inventory, manual front-desk logs, no reliable audit trail — or hand 15–25% of every booking to an OTA like Booking.com just to get reservations at all, with no direct relationship to their own guests. Reconciliation errors surfaced only after they'd already hit the books, and there was no way for guests to pay online with local cards (CIB/EDAHABIA).
