Turn Your Store Into a Multi-Vendor Marketplace
VendorIQ turns the Shopify store you already have into a fully operational multi-vendor marketplace — without leaving Shopify or migrating to a proprietary platform. Vendors sign up through their own portal, list products that sync straight into your catalog, and fulfil their share of every order. VendorIQ splits multi-vendor orders the instant they arrive, calculates commission automatically, and pays each vendor on the schedule you set. And a real AI layer runs across vetting, fraud, listings, disputes, and customer chat — so the marketplace largely runs, and polices, itself as it grows.
A Marketplace Is a Lot to Run by Hand
Adding sellers to a Shopify store means onboarding and vetting vendors, splitting every order, chasing fulfilment, calculating commission, and paying everyone — while keeping your storefront and your customers happy. Do it manually and it breaks the moment you grow. Move to a standalone marketplace platform and you leave Shopify behind.
The Operations Sprawl
Vendor applications, product approvals, order routing, fulfilment, returns, disputes, payouts — every new seller multiplies the manual work. Spreadsheets and inboxes stop scaling somewhere around your tenth vendor.
Leaving Shopify Is Worse
Standalone marketplace platforms mean a migration, a new storefront, a new checkout, and lock-in — throwing away the store, theme, and customers you already have just to add sellers.
Trust Doesn't Scale Itself
The more vendors you add, the more you have to police — who's legitimate, which orders look like fraud, which listings are weak, which returns are piling up. Miss it and it costs you chargebacks and reputation.
Everything a Marketplace Needs, Built In
Build it, run it, and settle it from one Shopify admin — vendor onboarding through payouts, with the storefront your shoppers see in between.
Self-Service Vendor Portal
Every vendor gets their own branded portal — they never touch your Shopify admin. Vendors apply, verify their business, list and edit products, watch orders arrive, fulfil their share, and track their own payouts, all in real time.
Automatic Order Splitting
Every multi-vendor order is split the instant it comes in. VendorIQ routes each line item to the vendor that owns it, creates a real Shopify fulfilment for their share, and keeps the customer's checkout and tracking exactly as they expect.
Commission Rules, Your Way
Flat percentage, fixed fee, margin cut, or tiers by revenue — set a global default, then override it by vendor, category, or product. Add conditions, rank rules by priority, and the most specific one always wins, calculated on every order.
Automated Payouts
Pay vendors by Stripe, PayPal, or manual bank transfer — on a weekly, biweekly, or monthly schedule, with commission deducted automatically and an optional hold window for returns. Money flows from your own accounts; VendorIQ never holds your funds.
Approve Before It Goes Live
New vendors, products, reviews, and questions wait for your approval by default — moderate everything from one queue, or flip on auto-approve for vendors you trust. Nothing hits your storefront without a check.
One-Pass Catalog Import
Already have a single-seller store? The catalog-import wizard scans your products, auto-detects the vendor behind each one, and wires up the links that power splitting, commission, and payouts — turning your store into a marketplace in one pass.
Your Vendors Run Their Own Shop
A standalone, mobile-friendly portal branded as your marketplace — so sellers manage everything themselves and you're not their help desk.
List & Fulfil
Vendors create and edit products (or bulk-import by CSV), manage their own inventory that syncs to your store, and fulfil orders with tracking — which sends the customer your standard Shopify shipping email.
Engage Customers
Vendors reply to reviews, answer customer questions, message your team, and run their own discount codes — all moderated by you, with AI to draft replies so nothing sits unanswered.
Track & Grow
Vendors see their sales, payouts, and payment status in real time, get demand and stockout forecasts, and can refer other vendors through a built-in referral program with a leaderboard.
A Marketplace Your Shoppers Can Browse
Drop-in theme blocks turn your store into a browsable marketplace — no theme editing, no code.
Vendor Pages & Directory
One click publishes a public vendor directory and a profile page for every approved vendor — with a deep link to add it to your store navigation. Pin your best sellers as featured vendors.
Reviews & Q&A
Product reviews and a customer Q&A, styled to match your brand and moderated from your admin — social proof that lifts conversion, with AI screening out spam and fakes.
AI Product Chat
An AI chat on your product pages answers shopper questions — "is this dishwasher safe?", "does it ship to Australia?" — from each vendor's own product info and your policies, so buyers get an instant answer instead of leaving.
An AI Layer Across the Whole Marketplace
Most marketplace apps stop at order-splitting math. VendorIQ ships real AI that vets your sellers, catches fraud, lifts your listings, and helps your customers — so the marketplace polices and improves itself as it grows.
Vendor Vetting & Verification
Every application is scored and every business document is read automatically — entity name, type, expiry — into a clear risk rating, so you know exactly who you're onboarding before they ever publish a product.
Order & Vendor Fraud Detection
Every incoming order is scored for risk using marketplace signals Shopify can't see — unusual velocity, value outliers, shipping/billing mismatches — and flagged before it's fulfilled or paid. It sharpens itself from your decisions.
Listing Quality & Enhance
Every product gets a 0–100 quality score with concrete fixes, and vendors can rewrite a title, description, bullets, and keywords in one click — so your catalog reads well without you chasing anyone.
Demand & Stockout Forecasts
AI projects each product's demand against its stock and warns vendors before they run out, with a suggested reorder quantity — so your best-sellers stay available.
Commission Optimizer
AI learns which commission rate actually maximizes your margin in each category — balancing revenue against keeping sellers active — and surfaces the change to make, with a one-line rationale.
Dispute Assistant
When a dispute is filed, AI weighs the order, the messages, and your policy, then suggests a fair resolution and drafts responses to both the customer and the vendor — faster, fairer outcomes with less back-and-forth.
Plus AI product categorization, review moderation, smart order routing, vendor-performance prediction, a vendor support assistant, marketplace-health alerts, and cross-shop benchmarks. Every AI feature has a sensible fallback, so the marketplace never breaks — it just runs leaner.
From Single Store to Running Marketplace
Set it up once — vendors and orders take care of themselves after that.
Install & Set Up
Install on your store, set your commission defaults and payout schedule, and invite your vendors — or open self-signup with a public landing page.
Vendors Onboard
Each vendor signs up in their own portal, passes AI vetting, connects a payout method, and lists their products — no Shopify access needed.
Orders Split & Fulfil
Multi-vendor orders split automatically; each vendor fulfils their share, and your customer gets the normal Shopify tracking experience.
Payouts Run
On your schedule, VendorIQ tallies each vendor's earnings, deducts commission, and pays out by Stripe, PayPal, or bank — automatically.
Your Store, Your Money, Your Control
You Never Custody Funds
Vendors are paid from your own Stripe or PayPal balance, or by a bank transfer you send. VendorIQ orchestrates the payout and deducts commission automatically — but it never holds or routes your money.
Shopify-Native & In Sync
Your checkout never changes. Vendor product and inventory edits sync back to your Shopify catalog, and "mark shipped" creates a real Shopify fulfilment — so shoppers get your standard tracking email and nothing oversells.
Private & GDPR-Ready
Vendor data is encrypted at rest and never sold or shared. All Shopify data-request, customer-redact, and shop-redact webhooks are honoured automatically, with a Data Processing Agreement available on request.
