The platform enables service-based businesses to accept 24/7 online bookings through embeddable widgets, Google Business Profile, a branded consumer app, and direct booking links, with automatic confirmations and reminders, calendar synchronization (Google, Outlook, iCal), subscription/membership management, and integrated POS and card payments via Mollie (including the new OA-Pay hardware terminals launched in 2025). Underlying architecture is a REST API with webhooks, single sign-on via secure hash, and Zapier endpoints, all hosted on dedicated ISO 27001-certified servers in the Netherlands with a 99.99% uptime SLA and OWASP penetration testing.

The company serves approximately 4,000+ businesses across the Netherlands and Belgium in verticals including medical and health, beauty and wellness, education, sports, leisure, retail, and government. Customers range from solo practitioners on the Solo tier (€20/month annual) to large franchise and government organizations on the Platinum tier (from €250/month with custom domain, dedicated account manager, and bespoke development). Pricing is tiered by resource count (Solo 1, Groei 2–10, Pro 11–20, Platinum unlimited) with add-on modules for POS (€15/month), Consumer App (€10/month), OA-Pay terminals (€10/month + transaction fees), SMS credits, and white-label custom-domain branding (€500 one-time). Go-to-market combines product-led self-serve signup with a 14–30-day free trial, sales-assisted demos for Platinum, and a white-label/channel program embedding the platform inside franchise networks and dealer associations.

Revenue mechanics span recurring subscriptions (primary), hardware sales of OA-Pay terminals, transaction fees on Mollie-routed payments (Maestro/V-Pay 0.20% + €0.06, consumer cards 1.80% + €0.10, business cards 2.90% + €0.10), SMS credit bundles, and a €500 one-time white-label setup fee.
