What Flex Booker does

FlexBooker is a cloud-based SaaS appointment scheduling platform founded in 2014 and headquartered in Columbus, Ohio. The platform enables service-based businesses across more than 11 verticals (including health and wellness, beauty, medical and dental, professional services, automotive, photography, retail, fitness, government, and organizations) to accept online bookings, manage employee schedules, and automate client communications. The core technology stack comprises an embeddable booking widget that auto-detects device type, bi-directional calendar synchronization with Google Calendar, Outlook, Office 365, Microsoft Exchange, and Apple Calendar, automated SMS and email reminder systems, an SMS-based waitlist, integrated payment processing, and native video meeting integrations with Zoom and GoToMeeting. The platform is delivered via web, iOS, Android, and a documented REST API for custom integrations.

The business operates on a tiered subscription model priced at $39-$99 per month based on employee count, with 1,000 bookings included per tier and overage billed in 500-booking blocks at $49. The primary go-to-market is product-led growth via a no-credit-card-required 14-day free trial, supplemented by an inside sales motion offering personal demos for enterprise prospects. Distribution is driven primarily by SEO through industry-specific landing pages and the embedded booking widget, with platform integrations into WordPress, SquareSpace, and Shopify extending reach into the small business website ecosystem. Enterprise-grade deployment is supported via the REST API and SSO through Google and Microsoft/Azure AD.

FlexBooker is a privately held LLC, 100% owned by its co-founders since founding, with no institutional investment, parent company, or acquisition activity disclosed. The company self-reports as consistently profitable and debt-free across 11+ years of operation, serving thousands of business locations and millions of end-users. Named enterprise customers include GoDaddy, Chipotle, Bausch, Briotix, and Complete Benefits Alliance, alongside a long tail of SMB accounts. The company explicitly restricts service availability to the United States, Canada, and the United Kingdom per its Terms of Use.
