KartSync - Multi-Vendor Marketplace Platform
Product details
KartSync
Run your own multi-vendor marketplace — on autopilot.
KartSync turns your idea into a complete online marketplace: sellers open their stores and manage themselves, shoppers buy from many stores in one cart, and you earn from every sale. Installed on your own hosting, under your own brand, with your data staying yours.
🏪 Unlimited sellers 🛒 One cart, many stores 💳 Card payments built in 🌍 6 languages + RTL 📱 Works beautifully on mobile 🌙 Light & dark mode
Why marketplace?
You don't need your own products to build a thriving shop.
A marketplace grows on other people's inventory. Sellers bring the products, photos and customer service; shoppers bring the demand; KartSync brings everything in between — and you collect a share of every transaction that flows through it.
Earn while sellers work
Set your commission once — platform-wide, per seller, or per category — and it's deducted automatically on every order. No spreadsheets, no chasing.
Sellers run themselves
Each seller gets a full dashboard: products, stock, orders, shipping, staff, earnings. You approve them once; they do the daily work.
You keep control
Approve or suspend stores, arbitrate disputes, review payouts, watch every payment in clear ledgers — the whole operation is visible from your admin.
Four ways the platform pays you
Built-in revenue streams, working from day one.
Sales commission
A percentage of every order, split per seller automatically. Negotiate special rates with key sellers and lock them in.
Seller subscription plans
Free, Pro, Plus — you design the tiers. Bigger listing limits, more staff seats and lower commission for paying sellers. Plans bill by saved card or from earnings, renew automatically, and land in your billing ledger.
Sponsored placements
Sellers pay to feature their products on the storefront — with budgets, per-click pricing and automatic impression tracking.
Gift cards & loyalty
Sell gift cards for upfront revenue, and keep shoppers coming back with loyalty points they can spend at checkout.
Three audiences, one platform
Everyone gets an experience built for them.

How it flows
The order journey, handled end to end.
A shopper fills one cart from many stores
They check out once, pay by card on a secure hosted payment page, and get a confirmation email — while stock reserves automatically so nothing oversells.
Each seller sees their part of the order
The order splits per store. Sellers pack and ship their items, buyers get shipped and delivered updates by email at every step.
Your commission is taken automatically
The seller's share lands in their wallet ledger; your cut stays with the platform. Every number is visible and exportable.
Problems resolve inside the platform
Returns follow a structured RMA flow; disputes get a message thread with you as the referee. Refunds flow back through the original payment.
Sellers cash out, shoppers come back
Sellers request payouts from their earnings; loyalty points, wishlists and review-request emails quietly pull buyers back for the next purchase.
Growth toolkit
Marketing muscle, included.
Flash sales
Time-boxed discounts with storefront countdowns that create urgency.
Coupons
Percentage or fixed discounts with limits, expiries and usage tracking.
