Hybrid marketplace: own shop + partner sellers · Belarus

Storefront, seller cabinet and moderation — one system
The task
The client needed a platform where their own goods and partner sellers’ goods sit on one storefront. Own goods sell with a cart and on-site checkout; partner goods via the seller’s own payment link, with the platform not a party to that sale. Sellers list products themselves, pass verification and pay for placement by subscription — and the buyer should never notice that the shop and the partners work differently.
Problems we solved
Two ways to buy on one storefront confuse the buyer and get tangled in the code.
An “Our shop” / “From the seller” badge on every card; own goods go to the cart and checkout, partner goods to an interstitial page and then to the seller’s link — only to whitelisted domains.
A seller without a cabinet calls the admin about every listing.
A seller cabinet: verification application and documents, five-step product listing with photos and per-category attributes, reviews, disputes, subscription and view statistics.
Third-party goods reach the storefront unchecked — along with stolen photos and swapped payment links.
A moderation queue with AI pre-check and a human decision, the rejection reason visible to the seller; payment links only to approved domains; blocking and unblocking recorded in the audit log.
The platform’s only revenue is seller subscriptions, and they can’t be tracked by hand.
Plans with a product limit, automatic suspension of listings when the subscription lapses and reinstatement after payment, invoices for legal entities, plan downgrade by request.
Reviews can be gamed, and personal data leaks from the database.
Review rights only after a confirmed purchase; personal fields encrypted at the column level, seller documents in private storage behind short-lived links, staff sign-in with a second factor.
The catalogue has to bring buyers in from search, not just display goods.
Server-rendered catalogue and product pages, Product/Offer/BreadcrumbList markup, sitemap, redirects for old URLs, filters by category, price, city and availability.
