The buyer's, the seller's and the operator's product, designed together.
-

Who buys, who sells, who runs it, and what each can do.
-
Buyer journeys
Search, listing pages, trust signals and checkout.
-

You receive
- Flows for every role
- A permission and state matrix
- UI and a clickable prototype
Designed for the deal between strangers.
Good marketplace UX design makes two people who have never met willing to trade. In B2B, B2B2C or C2C, each side gets its own journey and the operator sees both.
Every screen is designed for
- A side with no supply yet
- Listing waiting for review
- Seller not yet verified
- A search with no match
- Offer waiting for a reply
- Questions before the deal
- Payment held, payout pending
- Refund or dispute
- Account suspended
Marketplaces we have designed
Two- and three-sided products, each with the operator behind it.

When marketplace design is the right frame
It fits when the product only works if more than one side shows up and trusts the other.
-
More than one side must join
Buyers and sellers, or clients and providers, each need a reason to sign up and return.
-
Trust decides the first deal
Buyers want reviews and verified sellers before they pay; sellers want to know they will be paid.
-
Someone runs the market
Your team approves listings, settles disputes and releases payouts.
-
A build is planned
An in-house or partner team will develop the product from the design.
A different starting point
Let's design both sides before anyone builds them
Tell us who buys, who sells and who runs the market. We will come back with a useful scope and a realistic next step.
Scope, access and who does what
Marketplace work starts through the service that fits your stage, and its proposal sets the terms.
- Scope
- Per service set in the proposal you start with
- Timeline
- Agreed after scope, access and dependencies
-
You provide
- The product
- Access to the live marketplace or staging, with a test account for each side and the admin.
- Evidence
- Funnel data for each side, support and dispute themes, and where deals fall through.
- Decisions
- A product owner who can settle trade-offs between the sides.
- Engineering
- The team, the stack, and the payment and identity providers you use or plan to.
-
Who does what
- ANODA
- Maps the sides and the operator, designs the journeys, states and screens, and documents what engineering needs.
- Your team
- Shares access and context, reviews each step, builds the product and runs the providers behind payments and verification.
-
Boundaries
- Outside marketplace design
- Development, payment and identity provider setup, pricing and commission strategy, and legal or tax review.
- After the design
- Your team or partner builds the product. Implementation reviews are scoped separately when needed.
In the client's words
ANODA gave the marketplace a clearer design direction, from the first vehicle search to the seller journey. Bringing the identity and interface work together made it easier to review the product as a whole and decide what the development team should build.

Marketplace Design: common questions
How do we choose a marketplace design agency, and what should we ask to see?
Look for a team that has designed more than one side of a real marketplace and can show the work behind the screens: how a seller gets verified, what a buyer sees when a search finds nothing, how a dispute reaches the operator. Ask which roles they designed for, whether the operator's tools were designed or left for later, what was built and who on the team did the work.
What does marketplace design include, and what drives the cost and timeline?
A role and workflow model, the buyer and seller journeys, listings and search, reviews and verification, checkout and payouts, messaging, the operator's tools, a prototype and the UI with its states. Cost and timeline depend on the number of sides and roles, the platforms, whether the product is new or live, and the evidence you already have. The service you start with sets a custom scope in its proposal, and the timeline is agreed after scope, access and dependencies.
Which roles and workflows do you design for — B2B, B2B2C or C2C?
Buyers, sellers or providers, their team members, and the operators and support staff who run the market. The workflows are joining, listing, searching, comparing, messaging, making an offer, paying, getting paid, reviewing and disputing. The model changes the weight: B2B needs quotes, approvals and invoices; B2B2C design serves a business's tools and its customers' journey at once; C2C marketplace design leans hardest on identity, reviews and safe payment, because both sides are private people.
Which ANODA services fit a marketplace, and where do we start?
It depends on the stage. Product Discovery when the model or the first side is unclear; MVP Design for a first release around one core loop; UI/UX & Product Design for the whole product; a UX Audit when a live market loses one side; UI Redesign when only the interface has aged. Web App Design and Mobile App Design cover each platform, Dashboard Design the sellers' and operators' numbers, and Web App Development builds it. Availability and reservations belong to Booking & Reservation.
How do you handle trust, permissions, payments and edge cases?
With the flows, not after them. Each screen is drawn for a listing in review, an unverified seller, a search with no match, an offer with no reply, money held before payout, a refund, a dispute and a suspended account. A permission matrix sets out what each side and the operator can see and do. Messaging gets its own rules: what can be shared before a deal, and when the operator can step into a thread. For payments we design the states and messages around the provider you choose; its rules and compliance stay with your team.
What do you need from our team to start?
Access to the product or staging with a test account for each side and the admin, the funnel data you have for each side, support and dispute themes, a product owner who can decide, and contact with engineering and the payment and identity providers you use or plan to. For a live market, the moments when either side writes to support tell us most.
Which marketplaces have you designed?
Autodice, a car marketplace where dealers bid for the buyer — 3 roles served from one homepage. ParaVistaStays, a villa marketplace for travellers, hosts and creators — 347 unique screens. SpaceBridge, where owners offer space to charities — 2 user roles. Wildcast, a podcast-ad marketplace — 3 portals redesigned. EasyRent, a water-sports rental marketplace — 3 user roles: renters, suppliers and administrators. Each case shows its roles, flows and states, not only the finished screens.
Can you work with our live marketplace, design system and team?
Yes. Autodice, ParaVistaStays and Wildcast were all redesigns of products already in use. We work in your design files and system where they exist, alongside your designers and engineers. Where there is no system yet, we set up the parts a marketplace repeats — listing cards, filters, offer and payment states — and hand over everything we make.
