Service businesses struggle to connect with clients. Gwmart needed an app where vendors could showcase services and clients could book with confidence.
Small service businesses — from hair stylists to contractors — often lack the web presence to compete with larger companies. Clients struggle to find trusted vendors and compare services. Gwmart wanted to level the playing field: create a marketplace where any service vendor could list their offerings, manage appointments, and collect payments — all through one simple app. The challenge was building trust in a crowded marketplace while keeping the vendor onboarding process dead simple. 'Most marketplace apps are built for buyers,' Grace said. 'We needed to serve both sides equally well.'
Both vendors and clients tell us the app is 'just easy.' That simplicity required serious thought and great execution.
Grace Williams
Founder, Gwmart
We created a two-sided marketplace that works seamlessly for vendors and clients alike.
Using React Native, we built one app with two distinct experiences. For vendors: simple service listings with photos, pricing tiers, availability calendars, and built-in payment processing. For clients: smart search with filters, real-time availability, secure booking, and a rating system that builds trust. The backend (Node.js + PostgreSQL) handles complex scheduling logic — preventing double-bookings, sending automated reminders, and managing cancellations gracefully. We integrated Stripe Connect so vendors get paid directly without hidden fees. The app includes in-app messaging so clients and vendors can clarify details before booking. Everything was designed to reduce friction on both sides of the transaction.
From scattered vendors to connected marketplace — service businesses now have a professional home.
Gwmart launched with 500+ service vendors across multiple categories. The app reached 15,000+ downloads in the first two months. Vendors report 40% more bookings compared to social media alone. Clients love the ability to compare services and read verified reviews. The platform now facilitates thousands of bookings monthly with a 4.5-star rating. 'You gave small businesses the tools that big companies take for granted,' Grace said.
