KartSync - Multi-Vendor Marketplace Platform
Product details
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.
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.
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 straight from the seller's earnings, renew automatically, support free trials and fair mid-period switching, and every payment lands 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.
Everyone gets an experience built for them.

- Configure mail, payments, taxes, currencies, commissions and AI from friendly settings screens — no code
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.
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.
Abandoned cart recovery
Automatic reminder emails that bring shoppers back to finish checkout.
Affiliate program
Reward people for referring buyers with trackable links and commissions.
Featured products
Curated hero placements on the storefront — a perk you can tie to paid plans.
Lifecycle emails
Welcome, order updates, review requests, renewal reminders — branded and translated.
Wholesale and B2B, ready when you are.
Flip on the B2B tools and your marketplace also serves business buyers: wholesale-only products, request-for-quote negotiations with per-item counter-offers, approved-buyer terms and net-payment invoicing. Two markets, one platform.
Use cases our buyers build.
Niche craft market
A curated home for makers — handmade, vintage, art — with seller stories and storefronts.

Bring your city's shops onto one site with click-and-collect pickup points.
Vertical marketplace
Own one category — pet supplies, auto parts, baby gear — and become its go-to destination.
B2B supply hub
Connect distributors with retail buyers using quotes, terms and wholesale pricing.
Regional Amazon-style store
A general marketplace for a market the giants underserve — in its own language.
Brand + partners
Sell your own products and invite complementary brands to sell alongside you.
Speak your market's language. Follow its rules.
Translated out of the box
English, German, Spanish, French, Portuguese and Chinese included — every screen and email. Right-to-left layouts supported for Arabic-script markets.
Currencies & taxes
Display prices in multiple currencies and configure tax rates per region from the admin.
Privacy & compliance
GDPR-style data export and deletion requests, cookie consent, a consent log, and age-gating for restricted products.
Trust & safety
Two-factor login, rate-limited sign-ins, secure hosted card payments (card numbers never touch your server), and a full admin activity log.
From upload to open-for-business in an afternoon.
Guided installer
A friendly five-step wizard checks your server, connects your database and creates your admin account — with green ticks at every stage. No command line required.
Make it yours
Your name, logo, colours and tagline throughout — storefront, emails, even the app icon. KartSync disappears; your brand takes over.
Set your business rules
Commission rates, subscription tiers, payment keys, shipping and taxes — all from settings screens.
Invite sellers, go live
Sellers register, you approve, products appear. The marketplace flywheel starts turning.
💡 Yours, completely
KartSync runs on your own hosting with your own database. No per-month platform fees, no revenue share to us, no lock-in — your marketplace, your data, your margins.
Quality you can feel, even without reading the code.
Under the hood KartSync is built on Laravel — the world's most trusted PHP framework — and shipped with an extensive automated test suite covering payments, orders and billing. What that means for you: fewer surprises, smooth updates, and a platform that behaves the same on day 500 as it did on day one.
Your marketplace is a decision, not a project.
Everything above ships in the box: the storefront, the seller dashboards, the admin, the billing, the marketing tools. Add your brand and your sellers — KartSync handles the rest.
