Marketplaces are hard. You need supply and demand, trust systems, and payments all working together. We have built them before and know where founders trip up.

We have built two-sided platforms and know what breaks them

Most marketplace founders underestimate the complexity. A marketplace is two products in one — a buyer-facing experience and a seller or provider-facing experience — and both need to be good enough to attract the other side. Get the provider side wrong and buyers leave. Get the buyer side wrong and providers churn.

The biggest mistake we see is founders trying to build for both sides at once and ending up with a mediocre product on both. We help you choose which side to nail first, build for that audience, and then layer in the second side once you have enough traction to attract them.

Payments in a marketplace are genuinely complex. You are handling funds on behalf of other people, which means compliance, payout schedules, disputes, and refund logic all need to be considered upfront. We have built Stripe Connect integrations across multiple platforms and know where the edge cases live.

Marketplace trust is built through the product design — review systems, profile verification, clear dispute resolution, and communication tools. We wire these in from the start rather than retrofitting them once the platform has scale. Getting the trust layer right early is one of the highest-leverage decisions you will make.

Every type of two-sided platform

From service marketplaces to product platforms to rental networks, the underlying patterns are similar. Here is what we build most often.

Service marketplaces
Connect customers with service providers. From trades and home services to professional skills. Booking, quoting, messaging, reviews, and secure payments built in.
Product marketplaces
Multi-vendor platforms where multiple sellers list and sell products. Category management, seller dashboards, inventory tracking, and split payment processing.
Rental and booking platforms
Availability calendars, booking management, damage deposits, and review systems for rental platforms. Works for spaces, equipment, and short-stay accommodation.
B2B procurement platforms
Buyer and supplier matching for business procurement. RFQ workflows, bulk pricing, approved supplier lists, and purchase order management for enterprise buyers.

Marketplace questions, answered

How do you solve the chicken-and-egg problem for a new marketplace?

You pick one side first. Most successful marketplaces seed supply before demand — get the providers or sellers in place so that when buyers arrive, there is something to find. We help you build a launch strategy during Inception and design the product to incentivise the side you need first. There is no magic technical fix for this, but the right product design makes it much easier.

How much does a marketplace app cost to build in Australia?

A marketplace typically costs between $80,000 and $400,000 depending on the type of transaction, payment split complexity, trust features, and whether you need mobile apps, a web platform, or both. We scope every marketplace in Inception so you know exactly what you are committing to before a dollar is spent on development.

How do payments work in a two-sided marketplace?

We use Stripe Connect for most marketplace payment flows. It handles the split between your platform fee and provider payouts, manages identity verification, and supports instant or scheduled payouts. The configuration depends on your fee model and whether you hold funds in escrow before releasing them.

How long does it take to build a marketplace app?

A well-scoped marketplace typically takes 16 to 22 weeks from first call to launch. They are complex builds because you are essentially building two user experiences simultaneously — one for each side of the market. We build iteratively and prioritise the core transaction loop first.

Do I need to build a mobile app or can I start with web?

For most marketplaces, starting with a responsive web app is the faster, more cost-effective path. You can test whether the market works before committing to a native mobile build. Once you have traction, adding iOS and Android apps is much easier. We help you make this call during Inception based on your specific users and use case.

How do you handle trust and safety in a marketplace?

Reviews, ratings, identity verification, dispute resolution flows, and clear provider profiles are the foundation of marketplace trust. We build these as part of the core product — not as afterthoughts. The specific implementation depends on the type of transaction and the risk level involved.
