Custom booking platform and marketplace development

For founders building a two-sided platform

Booking platforms look simple from the outside: a search box, a calendar, a pay button. Underneath sit the hard parts. Availability must never double-book, prices change by season or demand, payments must reach the right host, and listing pages have to be found in search. Generic booking tools work well for one business taking appointments. They struggle when you have many hosts, your own rules and a brand to build.

I build custom booking and marketplace platforms for founders and operators in niche markets: venues, rentals, activities, local services, and directories that want to move from leads to paid bookings. If you're building a different kind of SaaS product, SaaS & MVP development is the better fit.

Proof from platforms I've built

CautElectrician.ro is a two-sided directory. Electricians across Romania sign up for free and keep a public profile with their status, while customers search by county and city, compare profiles and send quote requests, with moderated testimonials building trust. It runs on Nuxt 4 and Supabase, with structured data so county, city and profile pages get found in search.

On Smiles Casino I worked full-stack on the player site of a US social sweepstakes casino, with identity verification (KYC), payment integrations and prize redemptions. That is the same kind of money flow a marketplace depends on: who pays, who gets paid, and what has to be verified first.

How I approach it

We start with how money and availability move: who lists, who books, when a slot is held, when it's paid, and what happens on cancellation. Those rules become the core of the platform, and they are tested before any polish goes on top.

The work then ships in phases. The first phase takes real bookings and payments. Later phases add host payouts through Stripe Connect, pricing rules, reviews or more languages. Each week you test new flows on a staging site. Checkout, invoicing and payment edge cases are covered in more depth under e-commerce and payments.

What affects the price

Booking and marketplace projects start from €14,000; you get a fixed quote after a short scoping call. The price depends on how complex your availability and pricing rules are, whether hosts are paid out through the platform, how many user roles and languages you need, and which integrations, such as calendars, maps or invoicing, are required.

Talk through your platform

Tell me what people will book, who provides it and how you plan to earn from each booking. I reply within one working day, and after a short call you get a phased proposal with a fixed price. Get a quote for your booking platform.
