Marketplace development: structure and launch

By Daniil Belyaev · · 8 min read · updated

A marketplace is a platform with three parties: the buyer, the seller and the operator responsible for the storefront, the settlements and the rules. Technically it starts where an online store starts, but adds seller accounts, money moving between parties and moderation. In Uzbekistan the hardest part of such a project is not the catalogue but the settlement scheme with sellers.

Key takeaways

  • A marketplace differs from a store in three ways: seller accounts, splitting money between the parties of a deal, and moderation of the storefront.
  • Providing payment services without a Central Bank licence is prohibited, so settlements with sellers run through a licensed provider or an agency scheme.
  • Since 1 July 2025 sellers and e-commerce operators settle payments through separate bank accounts.
  • Selling through existing platforms is a way to validate demand without development: they provide audience and logistics but keep the rules and the buyer.
  • The first version of a platform launches in one category with a limited group of verified sellers, and automation follows once the economics add up.

How a marketplace differs from an online store

A store has one seller and one warehouse; a marketplace connects independent sellers with buyers and earns on the services it provides them. That means a different architecture and different day-to-day operations.

If there is only one seller on the platform, you do not need a marketplace: what that case requires is covered in how to launch an online store in Uzbekistan.

Your own platform or selling through existing marketplaces

Before building a platform, answer honestly why sellers and buyers need it instead of the existing ones. Uzum Market, Olcha, Sello and other platforms already operate in Uzbekistan, and for a seller joining them is a storefront without development.

Seller requirements — business registration, documents, bank details — and the joining procedure differ from platform to platform; they are published in the seller account and are worth reading in full before joining. When you build the platform yourself, you will have to write the same rules: who is admitted, what you check and on which terms you work.

For a manufacturer or distributor a workable strategy is to sell through other platforms and your own store first, and to build a platform once other sellers start coming to you. That is demand validation before development.

The seller account: without it the platform will not grow

The seller is the platform's second customer, and their account decides how fast the assortment grows without your team. At a minimum the account needs six things.

Structurally it is the same closed area with roles and permissions as a client portal, only with stricter checks: a seller changes data that every buyer sees.

Product import is a task of its own. Sellers arrive with different exports: a spreadsheet, a link to a price list, an exchange with an accounting system. The more formats the platform accepts, the less manual work moderators have and the faster the storefront fills up.

A catalogue built from many sellers' products

The main difficulty of a marketplace catalogue is identical products from different sellers. Without shared rules the storefront turns into a pile of duplicates with different names and photos.

Once enough purchase data has accumulated, selection and recommendations are added to the storefront: how that works is described in recommendation systems for a marketplace and an online store.

Money: who accepts payment and how it is split

The scheme where the platform collects buyers' money into its own account and later transfers it to sellers needs legal work in Uzbekistan. Providing payment services without a Central Bank licence is prohibited by article 15 of the Law On Payments and Payment Systems ZRU-578 of 1 November 2019; payment agents and subagents are excepted from that rule.

Important The financial scheme of a marketplace is agreed with a lawyer, an accountant and the payment service before development, not after launch. The data model depends on it: how deductions are calculated, when the obligation to the seller arises and at what moment documents are issued.

The technical side of accepting payments — invoices, statuses, provider notifications and reconciliation — is the same for a store and a platform and is covered in billing and payments on a web platform.

Moderation and the buyer's trust

A marketplace sells not the goods but the confidence that the order will arrive and match the picture. That is why the rules for sellers are written before the first hundred of them arrive.

Moderation is designed together with the interface: a moderator needs a task queue, rejection reasons and a history of decisions for each seller.

How a marketplace is launched: the first version

Launching an all-purpose platform at once is expensive and risky: it needs development, sellers and buyers at the same time. The workable order is a short first version in a single niche.

  1. Describe the niche and the parties: who the sellers are, who the buyers are, why you are more useful to them than existing platforms.
  2. Build the financial model: what the platform earns on and how money moves through the contracts.
  3. Set the boundaries of the first version: one category, a limited group of verified sellers, manual processes where automation costs more.
  4. Design the catalogue and the roles: buyer, seller, moderator, finance officer.
  5. Build the storefront, the seller account and payment acceptance under the agreed settlement scheme.
  6. Test the end-to-end path: from the product card to the payout to the seller and the refund.
  7. Add categories and automation after the economics of the first niche add up.
Tip Build manual operations into the first version: seller approval, card checks and payouts from a register. Automating them is cheaper in the second version, when you can see which exceptions actually occur and how often.

The first sellers come from your industry rather than from advertising: they are brought in by hand, and in a first version that is normal.

How much a marketplace costs and what drives the price

There is no price for a marketplace as a finished product: it is a platform whose scope is set by the financial model and the number of roles. For reference, development of an online store with a catalogue, payments and accounting integration starts from $10,000 with us, and a marketplace is that store plus seller accounts, settlements and moderation.

Formats and prices for development are on the service page website development, and integrations with accounting systems on the page ERP and integrations. Payment service fees and logistics costs are counted separately.

How we approach marketplaces

Syntra Systems starts with processes and money rather than screens: who the parties are, what the platform charges for, how money reaches the seller and which documents appear along the way. Your lawyer and accountant join the conversation at this stage.

We then define the boundaries of the first version and build it so that a second category and a second logistics scheme can be added without a rewrite. The seller account and moderation are part of the same project: without them the platform runs on your team's manual work.

Frequently asked questions

Can an online store be turned into a marketplace?

It can: the storefront, traffic and delivery are already there. What's added is a seller dashboard, settlements with sellers and moderation, and the product card is rebuilt so offers from different sellers can coexist in it. For reference, an online store with us starts from $10,000; a marketplace is a store plus those three parts.

Do we need a licence to collect buyers' money and pay sellers?

Article 15 of the Law on Payments and Payment Systems (ZRU-578) bans providing payment services without a Central Bank licence, with an exception for payment agents and subagents. Money is therefore split on the side of a licensed payment service, or handled under an agency scheme. Since 1 July 2025, e-commerce settlements run through dedicated bank accounts — agree the scheme with a lawyer and accountant before development.

What is the hardest part of a marketplace?

Not the code but the operations: attracting sellers, controlling card quality and deadlines, resolving disputes and keeping the economics sound. Technology supports those processes rather than replacing them, which is why the rules are written before the interfaces.

How do you attract the first sellers?

By hand and one by one: the first sellers need a clear benefit and help with uploading products, not advertising for the platform. Usually you take a narrow category, agree with a few suppliers you already know and test the whole path on them — from the product card to the payout.

How much does building a marketplace cost?

There's no fixed price — the scope is set by the payment scheme and the number of roles: seller, moderator, support, finance. As a reference point, an online shop with a catalogue, payment and a link to the accounting system starts from $10,000 with us, and a marketplace is a shop plus seller accounts, settlements and moderation.

Who's responsible to the buyer for goods and returns?

That's settled by the platform rules and the seller contract, which fix the refund procedure and how disputed orders are handled. Who counts as the operator of an e-commerce platform is defined by Cabinet of Ministers Resolution No. 885 of 26 December 2024. This decision is made with a lawyer before development, since it drives which statuses and documents the system needs.
