Marketplace app development
We build two-sided marketplaces for founders who need buyers and suppliers to find each other, transact, and come back. A typical first version is a standard web app at $16,000 with payments and payouts at $2,500 and an admin panel at $3,500; with mobile apps for both sides it moves toward $25,000 to $40,000. Our marketplace work includes rider and driver apps for WePlus, a ride-hailing platform, where real-time matching, live location, and payouts all had to work on day one. This page covers what a first version includes, the price range, the compliance points that matter for money moving between strangers, and how we keep the launch small enough to test demand.
Relevant work
WePlus: rider and driver apps for a ride-hailing platform, with matching, live trip tracking, fares, and driver earnings. The same two-sided pattern applies to services, rentals, tutoring, freelance work, and local commerce.
The typical first version
- Supplier onboarding with profile, listing, availability, and approval by your team.
- Buyer search with filters and location, listing pages, and a booking or checkout flow.
- In-app messaging so contact and payment stay on the platform.
- Stripe Connect payments: collect, hold, take a commission, and pay out.
- Ratings and reviews after each completed transaction.
- An admin panel for approvals, disputes, refunds, and moderation.
To launch smaller, build the buyer side first and onboard suppliers by hand through the admin panel. That can bring the build toward $9,000 plus payments.
Compliance notes
- PCI DSS. Card payments run through Stripe, so card data never touches your servers and Stripe carries the PCI burden. You complete a short self-assessment questionnaire.
- Know your customer. Paying suppliers requires identity verification. Stripe Connect handles it and collects tax details for 1099 reporting in the US.
- Marketplace facilitator tax. Many US states require marketplaces to collect sales tax on behalf of sellers. We wire in Stripe Tax or your tax provider and recommend you confirm obligations with your accountant.
- Consumer protection. Clear cancellation and refund terms, shown before checkout and applied automatically.
- Privacy. Location and messaging data are sensitive; we minimize what is stored and honor deletion requests.
What makes marketplaces hard
The software is rarely the hardest part; liquidity is. A marketplace with great code and no suppliers is empty. That is why we push for a narrow first market, one city or one category, and an admin panel that lets your team do by hand what the product will automate later. The second hardest part is money: refunds, partial cancellations, disputes, and payout timing. We design these flows in the plan, before design starts, because they shape every screen.
How we work
Every first version starts with a signed plan listing every screen and workflow, then a clickable design you approve on your phone, then the build, then launch. You get a written weekly plan, a daily update, and a demo every Friday. You pay in four equal milestones tied to those stages, and you own the code and the cloud accounts from day one. After launch, a care plan from $1,000 a month or a dedicated engineer at $8,500 a month keeps the product moving.
What we leave for later
The fastest way to a marketplace product that earns its keep is a first version that does fewer things well. These are the items we usually move to after launch, once real usage shows they matter:
- Advanced search ranking and recommendations
- Supplier subscriptions and promoted listings
- Native mobile apps for the supply side
- Multi-city or multi-currency support
- Automated dispute resolution
Each one is a fixed-price addition later. Leaving them out keeps the first version inside the range above, shortens the time to launch, and means you spend on what customers actually ask for.
Timeline and team
A lean first version ships in about 5 weeks, standard in about 8, and large in about 12. A typical team is a product designer, two or three engineers, and a delivery lead you talk to every day, with a senior engineer reviewing every change. You see the work every Friday, and you can stop after any milestone with the code and designs in your hands.
Questions founders ask
How much does a marketplace app cost?
Most first versions run from $16,000 plus payments and admin on web, to $40,000 or more with mobile apps for both sides.
Do you build with Stripe Connect?
Yes. It handles supplier identity checks, payouts, and keeps card data with Stripe for PCI purposes.
Can you build real-time matching?
Yes. We built it for WePlus's ride-hailing apps, including live location and trip tracking.
Which side should I build first?
Usually the demand side, with suppliers onboarded by hand through the admin panel.
How fast can we start?
Usually within two weeks of a signed plan. The first week is design, and you see screens by the end of it.
Can you work alongside our own engineers?
Yes. Many clients keep an in-house lead and add our engineers to the same repository, stand-ups and review process. We follow your conventions, document what we build, and hand over cleanly whenever you want to take a piece of work in house.
Do you sign an NDA before the first call?
Yes, on request. Several of our clients, including a consumer AI company, work with us under NDA, and we never show their work without written permission.
What happens after launch?
Most clients move to a care plan from $1,000 a month for fixes and small features, or keep one or two dedicated engineers at $8,500 a month each.
