Fons is a streamlined practice management platform built to eliminate the administrative headaches of running an appointment-based business. Instead of chasing payments or manually coordinating calendars, you get an automated system that handles booking, reminders, and instant billing. You can set up your personal booking link, allow clients to schedule themselves, and automatically collect payments the moment a lesson or session ends. The platform focuses on the relationship between you and your clients by removing the friction of 'business talk' regarding money. You can manage your entire studio from your phone or desktop, track your income in real-time, and provide a professional portal for your clients to manage their own schedules. It is designed specifically for solopreneurs and small teams who want to spend more time teaching or coaching and less time on spreadsheets.

Mollie is a flexible payment platform designed to help you grow your business by simplifying how you accept money online. Instead of managing multiple contracts with different banks, you get a single solution that supports major credit cards, digital wallets like Apple Pay, and local European methods like iDEAL and SEPA. You can integrate the checkout experience directly into your website or use pre-built plugins for popular e-commerce platforms. The software focuses on transparency and ease of use, providing you with a clear dashboard to track transactions, handle refunds, and manage payouts in real-time. It scales with your volume, offering a pay-as-you-go model that ensures you only pay for successful transactions. Whether you are a small boutique or a high-volume international retailer, you can customize the checkout flow to match your brand and boost conversion rates.
