What marketplace development services do you provide?

Innowise provides end-to-end marketplace development services, so you’re not juggling five vendors. Our team covers product strategy and requirements, UX/UI for buyer, seller, and admin flows, custom marketplace software development, web and mobile apps, integrations with payments and your core systems, QA, launch support, and post-release updates once real users start pushing the platform.

How is a custom marketplace different from a ready-made marketplace platform?

A custom marketplace gives you more say in how the platform runs: your business logic, your user flows, your integrations, your codebase. A ready-made platform can be a good option when you need to launch quickly, and your requirements are fairly standard. As the marketplace grows, though, that convenience can start to wear thin, especially when you need changes that go beyond the default setup.

Do you develop both web and mobile marketplace applications?

Yes, our marketplace development agency builds both marketplace websites and mobile apps. Depending on the product, we can deliver iOS, Android, or cross-platform apps, all connected to a shared backend and one business logic layer, so the experience stays consistent across channels.

How long does it take to build an online marketplace?

A fully functional online marketplace usually takes 3 to 9 months to build. If the goal is to launch faster and test the model early, an MVP can go live in 4 to 8 weeks. The timeline depends on the route you take. No-code tools and ready-made solutions move faster because much of the base is already in place. Custom development takes more time, especially when the platform includes complex workflows, integrations, and marketplace logic. For a custom-built product, 6 months or more is a common range.

What technologies do you use for marketplace software development?

Our marketplace software development company uses modern web and mobile stacks, cloud infrastructure, APIs, and secure payment integrations selected around your product goals and technical requirements. The final choice depends on scale, feature set, and integration needs.

How much does it cost to develop an online marketplace?

The cost can vary widely depending on the development approach and the marketplace itself. A turnkey marketplace MVP typically costs around €7,500–€13,000, while platform-based projects typically fall in the €18,000–€92,000 range. Complex custom enterprise marketplaces can start from around €95,000.
The final estimate depends on functionality, integrations, seller workflows, transaction logic, data migration, infrastructure, and the selected technology.

What is a multi-vendor marketplace?

A multi-vendor marketplace is a platform where multiple independent sellers or service providers offer products or services to buyers through a shared storefront.
The marketplace operator typically manages the platform, seller rules, commissions, payments, catalog standards, and customer experience, while vendors manage their own listings, pricing, inventory, or services.

Should I build a custom marketplace or use an existing marketplace platform?

It depends on the complexity of your business model.
A SaaS or turnkey marketplace platform is often a good choice for validating an idea quickly. Platform customization works well when you need differentiated workflows and integrations but still want to build on proven technology.
Custom marketplace development is usually better suited to complex B2B models, unusual transaction logic, enterprise integrations, multi-region operations, or requirements that standard platforms cannot support cleanly.

Which marketplace platform should I choose?

Start with your business requirements rather than the platform name.
We usually look at your marketplace model, number and type of vendors, catalog complexity, payment flows, integrations, expected scale, customization needs, budget, and target launch date. From there, we can compare suitable options such as Sharetribe, Mirakl, Marketplacer, Adobe Commerce, commercetools, Shopify, CS-Cart, Spryker, Medusa, and others.

Can you integrate a marketplace with ERP, CRM, PIM, and payment systems?

Yes. We integrate marketplaces with ERP, CRM, PIM, OMS, payment gateways, accounting systems, logistics providers, analytics platforms, marketing tools, and other business software.
We can work with APIs and middleware or build custom integration layers when standard connectors are not enough.

How do marketplace payments and vendor payouts work?

Marketplace payment flows usually need to separate the customer payment between the marketplace operator and one or more vendors.
Depending on the business model, the system can support commissions, split payments, scheduled payouts, refunds, reconciliation, statements, taxes, and escrow-style flows. We design the payment setup around your commercial model and the capabilities of the selected payment provider.

Can you migrate an existing marketplace to another platform?

Yes. We can migrate marketplace data and workflows to a new platform or a custom solution.
That can include vendor accounts, customer data, catalogs, pricing, order history, content, integrations, and other business-critical information. We also plan the migration and rollout to minimize disruption to buyers, sellers, and internal teams.
