Everything you need to know about ClientFlow

ClientFlow is built for service professionals with recurring clients: fitness studios & personal trainers, music & language tutors, yoga instructors, martial arts schools, swimming coaches, freelance consultants, subscription box businesses, cleaning services, and any business with regular clients who pay monthly.

Most users are up and running in under 5 minutes. Simply sign up with Google, add your clients (or import from a spreadsheet), and start tracking payments immediately. No technical knowledge required.

The free tier allows you to manage up to 5 clients with full access to payment tracking, WhatsApp link generation, email reminders, and 3 message templates. No time limit, free forever. Perfect for testing or small operations. Upgrade to Starter ($14/mo) for unlimited clients and more features.

Free users can generate wa.me links that open WhatsApp with a pre-filled, personalized message including the client name and amount due. PRO users can send automated messages directly through the official WhatsApp Cloud API - just click "Send" and reminders go out automatically. Email reminders are free for all users.

Yes! Create unlimited message templates with dynamic variables like {{name}}, {{amount}}, {{month}}, and {{due_date}}. Each template auto-fills with client details when you send a reminder. Save time while keeping messages personal.

ClientFlow tracks any payment method your clients use - cash, bank transfer, credit card, PayPal, or any other method. Simply mark payments as paid, partial, or unpaid. We don't process payments - we help you track and follow up on them.
