Ready-to-launch booking app with Stripe deposits & Serverless backend.
HoldMySlot is a production-ready, multi-platform scheduling SaaS built for service professionals (hairdressers, mechanics, therapists, etc.) to completely eliminate no-shows and automate booking management. The platform is designed as a turnkey B2B2C marketplace where providers can onboard, set their services, and require dynamic upfront deposits via Stripe. Built on an ultra-modern, serverless tech stack, the codebase is designed for scalability with near-zero maintenance costs. Core Value Proposition & Features: Stripe Connect Integration: Fully automated provider onboarding, KYC, and payment routing. Deposit & Refund Engine: Automated deposit capture to protect against no-shows. If a client cancels before the deadline, they are automatically refunded; if after, the provider keeps the deposit. Complex Scheduling Algorithm: Real-time availability calculation preventing double-bookings and respecting edge cases (dynamic service duration, custom working hours). Multi-Channel Notifications: Granular communication system including Push Notifications, transactional emails (via Resend), and 1-click WhatsApp/SMS deep-linking. SaaS Dashboard: A clean, intuitive dashboard for providers to view their agenda, manage conflicts, and track revenue. Tech Stack: Frontend: React Native with Expo (Ready for iOS, Android, and Web deployment). Backend: Supabase (BaaS) utilizing PostgreSQL for robust relational data and Row Level Security (RLS) for rock-solid privacy. Logic: Deno Edge Functions for secure serverless operations (handling Stripe webhooks, slot algorithms, and emails) ensuring 0ms cold starts. Payments: Stripe API (Checkout Sessions & Connect). Why Buy This? This is not a simple template; it is a fully functioning business engine. The most challenging technical hurdles of building a marketplace—multi-party payments, complex time-zone aware scheduling, and serverless background tasks—have already been solved. It is perfect for an agency wanting to white-label a booking solution or an entrepreneur ready to launch and market a scheduling SaaS immediately.

Reason for selling
I am a developer at heart, and I built this project to solve a complex technical challenge: creating a flawless, automated scheduling architecture with dynamic Stripe deposits to solve the "no-show" problem in the service industry. The product is now 100% finished and production-ready, but I do not have the marketing skills, time, or capital to acquire users and run a B2B SaaS. I prefer to sell the technology to someone with distribution in the salon/services industry or to an agency that wants to white-label it.
