How to Build a Multi-Vendor Marketplace App: Features, Payments and Launch Plan

We built SkyeOne, an event booking marketplace that brings venues, caterers and decorators into one place. Most of what follows comes from that kind of work: the parts founders underestimate are always the vendor tools and the money flow.

The three sides you are building

Payments and commissions

Marketplaces need split payments: collect from the customer, keep your commission, pay each vendor. Use a gateway built for this, such as Razorpay Route in India or Stripe Connect internationally, instead of handling vendor money yourself. Decide early how refunds and cancellations affect the split.

Vendor onboarding

Start manually if needed: your team onboards the first vendors, checks documents and sets up listings. Self-service onboarding can come later. Verification protects your brand; a single bad vendor damages trust for everyone.

What to launch first

• One city or region.
• One or two categories.
• The core flow: discover, book, pay, review.
• A simple vendor dashboard and an admin panel.

Everything else, such as loyalty, advanced search and vendor analytics, waits until the core flow works. Our scoping framework helps decide what waits, and the cost of an MVP explains where budget goes.

Trust and quality

Reviews only from real transactions, clear refund rules, verified vendors and fast support. Real-time availability matters too: in SkyeOne it removed the back-and-forth phone calls that slow event bookings.

Solving the chicken-and-egg problem

Buyers come for choice, and vendors come for buyers. Most successful marketplaces start by narrowing the focus:

• One city or neighbourhood before expanding.
• One category where you can sign enough vendors by hand.
• Supply first: onboard vendors personally and help them list well before you spend on buyer marketing.
• Do things that do not scale at the start, such as manual matching or phone support, and automate once patterns are clear.

The admin panel matters more than you think

Your operations team will live in the admin panel. Plan for vendor approvals, listing moderation, order overrides, refunds and disputes, commission settings, payouts and reports. A weak admin panel means your team runs the marketplace from spreadsheets and chat groups.

Common mistakes

• Launching in many categories and cities at once.
• Building complex vendor tools before you have vendors.
• Handling split payments manually instead of using a gateway's marketplace features.
• No clear refund and dispute policy before launch.

Technology choices

A marketplace usually needs a mobile app or responsive web app for customers, a web dashboard for vendors and admins, a backend with search, payments and notifications, and real-time updates for availability.

At Creuto we start marketplace projects with a PRD that maps all three sides and the money flow before any design begins.
