A marketplace that earns you commission while sellers earn
We design a multi-vendor platform around your process: from a thousands-of-SKU catalogue to splitting payments across dozens of sellers. Not a template or a builder — a product that survives growth.

A marketplace is not “a store with extra pages” but a distinct architecture: roles, payouts, moderation, commissions and load. We start from the data model and business process, not the design, so the platform scales without a rewrite.
Sound familiar?
The moment there is more than one seller, a regular store breaks down:
- Payments and commissions get reconciled by hand in a spreadsheet
- Sellers leave because there is no dashboard, or it is unusable
- A thousands-SKU catalogue drags search, filters and checkout
- No transparent analytics: who sold what, and when
What you get
Seller dashboards
Private panels, product uploads, order statuses, roles and moderation — each seller sees only their own data.
Unified cart & payouts
A Stripe Connect / WayForPay checkout: split the payment between sellers, take the platform commission, report it cleanly.
Scale without drag
Search, filters and a thousands-of-SKU catalogue on a fast frontend — no slowdown as the range grows.
Integrations & analytics
Stock sync with warehouse / ERP, logistics, CRM and an owner dashboard with key metrics in real time.
Trust and repeat sales
Ratings, reviews and a cashback loyalty program — what brings the buyer back to the platform.

Questions owners ask
How much does marketplace development cost?
The budget depends on seller types, integration depth and catalogue size, so we lock it after a free brief. See the entry tiers above — the “turnkey store” whose architecture a marketplace is also built on.
Will you migrate an existing store without losing traffic?
Yes. First we capture the SEO baseline — donor pages, links and structured data. Then a page-by-page migration against the same intents, a redirect map covering 100% of URLs and 90 days of post-launch rank monitoring.
Can you build in commissions and seller payouts?
Yes. We wire payment splitting through Stripe Connect: each seller receives their share, the platform takes its commission, and you get transparent reporting on every transaction.
Which platform survives thousands of products?
The product is built on a fast frontend and a well-designed data model: filters and search stay responsive at large assortments, while load is handled by caching and background jobs.
Can I run the platform myself?
Yes. The moderation admin, roles and seller dashboards are built so your team manages content and operations without a developer for every step.
