A travel marketplace lives or dies on its hosts. Before you design screens, line up the first partners who will list stays, tours, guides or workspaces, and decide how money moves when a trip is booked, changed or cancelled. Then build the side that brings the supply first. With us, a first version of a marketplace app typically costs $5,000 to $15,000 and takes 2 to 4 weeks, plus store review.
This guide is about the two-sided business: travellers on one side, hosts or partners on the other. If you’re building an app for travellers on top of someone else’s inventory, read our travel app development guide instead.
| Part | Questions to settle before the build | What breaks if you don’t |
|---|---|---|
| Supply | Who lists first, and why would they bother? | Travellers search and find nothing |
| Listings | What must every listing include, and who checks it? | Photos and prices that don’t match reality |
| Booking rules | Instant booking or request first? How far ahead? | Double bookings and angry hosts |
| Money | Deposit or full payment? When do hosts get paid? What’s your fee? | Refunds paid out of your own pocket |
| Cancellations | Who can cancel, until when, and who pays for it? | Disputes you settle by hand |
| Trust | Reviews, checked profiles, a way to report someone | Fake listings and no-shows |
| Price display | Does the first price include every mandatory fee? | Legal trouble in some markets and lost trust |
A marketplace with no hosts has nothing to sell, so the first version usually serves the side that brings the supply. Traza, a marketplace for tattoo artists in Australia, worked this way. Its artists already took bookings on the website, and the first app was for them, so they could run bookings from their phone (Traza case study).
In travel, supply often means partner companies rather than individuals. FlyDesk, a marketplace for coworking desks and meeting rooms, lists 577 offers in 26 countries from 44 partners, including WeWork. Big partners bring many listings at once, but each one has its own data, prices and rules to keep in sync.
Sign the first hosts by hand. Talk to them before you build their screens: how they take bookings today, how they want to be paid, and what makes them cancel.
The market won’t do this for you in 2026. UN Tourism counted about 690 million international tourist arrivals in the first half of the year, only 0.4% more than a year earlier. With demand that flat, a new marketplace wins bookings by having stays and tours the others don’t, which brings you back to signing hosts.
Every booking moves through states, and each state has a money rule. Write them down before anyone designs a screen.
| Booking state | What happens to the money |
|---|---|
| Requested | Nothing yet, or a card hold if the host must confirm |
| Confirmed | Charge the deposit or the full price |
| Cancelled early by the traveller | Refund by your policy, minus any non-refundable fee you showed up front |
| Cancelled late by the traveller, or a no-show | The host keeps the deposit or part of the price |
| Cancelled by the host | Full refund to the traveller, plus your rule for what the host owes |
| Completed | Pay the host, minus your fee |
| Disputed | Hold the payout until someone on your team decides |
One detail shapes the whole flow: an online card hold usually lasts only 7 days. For trips booked further ahead, charge the deposit and refund it by your rules. Traza’s artists take deposits and mark each session complete, no-show or cancelled, and each booking shows only the actions that fit its stage. Our guide on how to create a booking app with deposits walks through the deposit flow step by step.
Travellers pay you once, and hosts expect their share on time. Stripe Connect is built for this: a marketplace collects payments from customers and automatically pays out a portion to sellers or service providers. Stripe checks each provider’s identity before it pays them.
Check coverage before you choose a provider. On Hoozin, an event app we built, the plan was to take ticket payments through Stripe. The team switched to PayPal to reach more markets, because PayPal works in over 200 countries. Your host list tells you which countries you need on day one.
Fees that appear only at the last step of checkout are now a legal problem in some markets. In the US, the FTC’s Rule on Unfair or Deceptive Fees took effect on May 12, 2025. It covers short-term lodging and live-event tickets, and it requires businesses to tell consumers the total price, with fees, up front. If your marketplace lists stays for US travellers, put the total price in search results from the first version.
In the EU, selling two or more types of travel services for the same trip, such as a flight and a hotel, can make you the organiser of a package. The organiser is responsible for every service in the package, and travellers are protected if the trader goes bankrupt. If you plan to bundle, talk to a lawyer before you build the checkout. This guide isn’t legal advice.
Short-term stays in the EU have a new rule too. Regulation (EU) 2024/1028 on short-term rentals has applied since 20 May 2026. According to the European Parliament’s summary, each rented unit gets a registration number so that the data platforms share can be matched to hosts and units, and platforms regularly send information about rental activity to a single digital entry point in each member state. Countries set up registration differently, so check each market you list in. Put a registration number field in the host listing form from the first version, and plan a regular data export.
Travellers book rooms and tours from strangers, so trust features belong in version one. Ratings after each trip, checked profiles and a way to report someone are the basics. On Luanda, a listings marketplace we built, ads are verified with a code sent to the seller’s phone or email. In Traza, the artist and the client chat inside each booking, so the whole history sits in one place.
Stays, tours and transport happen in the real world, so Apple requires a payment method other than in-app purchase, such as a card or Apple Pay (guideline 3.1.3(e)). That means the app stores don’t take a share of the booking. Digital extras sold inside the app follow other rules, so check each one separately.
A first version of a marketplace app typically costs $5,000 to $15,000 with us and takes 2 to 4 weeks, plus store review. An app for one side, built on a website and API that already work, is the fastest start. Both sides from scratch take longer, and deposits, split payments, refunds and payouts in several countries each add work. Our marketplace app development page shows how we scope it.
You can see what your marketplace idea costs to build with our project estimate before you talk to anyone. It turns your brief into user stories for both sides. You confirm what is in scope, and every hour in the budget traces back to a story you kept. We check the hours the AI suggests against what our team actually books on finished projects, then multiply by our published rate of $39-55 an hour. The discovery option also names customer groups you could sell to and gives each a market size (TAM, SAM and SOM) with a note on what the number covers. Treat those as hypotheses to test, not verified demand.
Below is an example run of the estimate’s math with sample inputs, for a local services marketplace with a client app, a provider dashboard and online payments. Every input is an assumption. Only the arithmetic is ours.
| Input (assumption) | Value | Output | Value |
|---|---|---|---|
| Work items | 12, in 7 phases | Budget | $8,100 to $16,700 |
| Revenue a month per paying customer, from your fee | $14 | Timeline | 4 weeks |
| Margin | 80% | Customers who pay for the build ($12,400) | 214 |
| Months a customer keeps paying | 8 | First month that earns more than it spends | Month 3 |
| Cost to win a customer | $30 | Month the build is paid back | Month 7 |
| New customers a month | 150 |
Change the fee or the cost to win a customer and the payback month moves. That shows you which guess to test first with real hosts and travellers.
Most take a fee on each booking before the host is paid. Some also charge hosts for promoted listings. Luanda, a listings marketplace we built, sells paid ad packages and shows premium ads on its main page.
Use a payment provider built for marketplaces, such as Stripe Connect, which collects from the traveller and pays the host’s share to the host’s account. Check that it supports every country your hosts are in. Hoozin moved from Stripe to PayPal for that reason.
In the US, the FTC’s fees rule has covered short-term lodging since May 12, 2025, and requires businesses to tell consumers the total price, with fees, up front. Other countries have their own rules. Showing the full price everywhere saves you from rebuilding checkout later.
The side that brings the supply. Travellers leave if they find nothing to book, so sign hosts or partners first and give them the tools they need, as Traza did with its artist app.
Who can cancel, until when, what gets refunded and who pays the payment fees on a refund. Write it before the build, because each rule becomes a booking state and a money movement in the app.
