Turnkey marketplace development: sellers, buyers, commission
A marketplace connects two sides and earns on every deal. We build it turnkey from €34,900 after an architecture session, and the code and accounts are registered to you.
Platforms and SaaSTimeline: after the architecture session
What a two-sided marketplace looks like
You need a marketplace when you do not sell yourself but connect those who offer with those who search: sellers and buyers, specialists and clients, schools and parents. Your income is a commission on every deal or a listing fee. The main challenge is attracting both sides: without sellers there is nothing to show, without buyers sellers have nothing to do.

- How to create your own marketplace: where to start. Choose one niche and one side to start with, usually sellers. Launch a minimal version, check that deals happen and only then expand the features.
- Marketplace business model. A commission on every deal, a seller fee for listing, a subscription for extended features, or a mix of these. The model determines how accounts and payment are built.
Approximate display: images and texts are chosen as an example. In your project the features, design and architecture will be different, built for your goals.
Marketplace — from €34 900
A platform where two sides meet, for example sellers and buyers or providers and customers. You earn a commission on every deal.
GRONO is a cashback platform for private education with payments and rewards. International Lyceum Discovery School has accounts for different roles and a CRM. Trendo is a platform with an internal currency and billing. duck.credit is online lending with scoring and an account area. These projects are closest to marketplace tasks: roles, payments, applications and accounts. See also: SaaS service with subscription.
- What we honestly do not call a marketplace. The projects listed are not marketplaces in the strict sense, but their modules will be useful for your platform: login, roles, payment, emails and an admin panel.
We show prices upfront and do not hide them behind a quote on request. The design is built for your niche, with no templates. The code is in your repository, and the domain and service accounts are registered to you. Infrastructure costs €0 at the start, and we take login, roles, payment and email modules from ready projects, so we do not write them again. See also: turnkey platform.
- Custom development or a ready-made builder. A marketplace builder is faster but limits commission logic and design. Custom development pays off if your model differs from the standard one.

What is included in a marketplace from €34,900
One price for the whole list: no extra charges for hours or individual items.
A marketplace starts from €34,900 and is developed after an architecture session for €3,500, the amount of which is credited toward the project. It includes seller and buyer accounts, a catalogue and search, responses and orders, reviews and ratings, commission calculation, an admin panel that needs no programmer and emails about actions. Payments and payouts are connected for your country. See also: architecture session, B2B catalogue and wholesale.
- Multi-vendor marketplace. Multi-vendor means many sellers work on the platform, each with their own account, products and orders. The platform calculates commission itself and shows reports.
- B2B marketplace. For B2B, company roles, counterparty verification, requests for quotes and invoices matter. We define the feature set at the architecture session.
- Architecture sessionFirst comes the product map and an exact estimate: how the two sides work, the commission and the payments. The €3 500 for the session is credited toward the project price.
- Platform foundationLogin, roles and data protection for buyers, sellers and staff.
- Seller accountSellers create their own listings, set prices, accept orders and see their payouts, so you do not need a manager for each of them.
- Buyer storefrontSearch, filters and "near me". Buyers quickly find what they need from several sellers at once.
- Requests and dealsEvery order follows a clear path: request, confirmation, delivery, closing. You can see where a deal got stuck.
- Reviews and ratingsAfter a deal both sides leave ratings that show on the profile. It is easier for buyers to choose, and sellers have something to be proud of.
- Commission and payoutsThe platform automatically keeps its share and pays the rest to the seller. We choose the payment scheme at the session.
- Admin panel and moderationReview of new sellers and listings, disputes, users and reports. The quality of the marketplace is in your hands.
- Emails and notificationsBoth sides learn about requests, statuses and payments right away. A seller never misses an order.
- Launch and handoverWe connect the domain, check deals and payouts on test data, and hand over access and instructions.
Approximate display: images and texts are chosen as an example. In your project the features, design and architecture will be different, built for your goals.
What to add to a marketplace
Optional, now or later. The price is fixed before work starts.
We adapt the platform to the market: language, jurisdiction, payment systems, currency and legal pages. We prepare seller terms and refund rules as templates for your country; your lawyer does the final check. We work with clients from Europe, the US, the UK, the UAE and Kazakhstan. See also: payment and delivery.
- Seller payouts and commissions. The payout method depends on the country and the payment service. We will choose an option at the architecture session and include it in the estimate.

Turnkey promotion: where your customers will come from
A platform does not attract users by itself: channels bring them in.
A platform earns when people sign up and pay. Turnkey promotion: search and articles, emails for new users, ads and partners. The report shows the path from visit to payment for each channel.
Most often we start with search and an email sequence: they keep working after the ads are switched off.
Turnkey promotion: stages and prices
Every month you get a report: how many requests came in and what each one cost. You pay the ad budget directly to the platforms.
So customers keep coming every month, not just on launch day
We will choose 1–3 channels for your business and budget, launch them, and show you every month what a request costs.
How we develop a marketplace
The steps switch automatically, or click any of them to read more.
At the architecture session we map the seller and buyer journey and choose the revenue model and the first version. Then we build the design and the platform foundation, adding the catalogue, deals, reviews and payment. We launch first with a small group of sellers to check that deals happen, then open the platform more widely. We name the timeline in the plan after the session.
- How to attract the first sellers. Start with personal agreements and an easy way onto the platform. We build simple login and invitation emails so it is easy for a seller to begin.
1. Brief
A short 15-minute questionnaire: what the business is, who it is for, what you need and by when. By voice, text or a call.
- We ask only what affects the result and the price
- Materials (logo, photos, texts) can be sent later
- We reply the same business day: what we offer, what it costs and how long it takes
2. Quote and contract
We fix the scope, price, deadline and payment schedule. The amount does not grow without your written consent.
- A contract between our company and yours, or with you personally
- Inside: the scope item by item (as on this page), deadlines, payment stages, warranty fixes
- The code, domain and service accounts are yours: it is written in the contract
- We sign online: a PDF with an e-signature, no paper and no couriers
3. Payment
We invoice your company. Pay by bank transfer or by card.
- No hidden fees: you pay for the domain and service subscriptions directly to them, with no markup from us
- Every payment is tied to a stage: you pay for what you can already see
- Closing documents: invoice and acceptance certificate
4. Trabajo con vista previa
At every stage you get a preview link: you see what is ready and leave your edits right away.
- First the product map and structure, then design, then the build
- We collect edits in one place, so nothing gets lost in the correspondence
- Questions for you come as a list with answer options: reply when it suits you
5. Review and approval
Before launch we check everything ourselves, then you approve the work against the list from the contract.
- Phones and computers, loading speed, forms and emails, payments in test mode
- Legal pages and the cookie banner are in place
- You go through the scope list and sign the acceptance certificate
6. Launch and handover
We publish on your domain and hand everything over to you: access, instructions, source files.
- Domain, email on the domain, analytics and Search Console
- Access to all accounts goes to you, we stay on by invitation
- A short guide: how to edit texts, photos and prices yourself
- After that, if you wish: support, promotion, new modules
