Turn Your Store Into a Multi-Vendor Marketplace
VendorIQ turns the Shopify store you already have into a multi-vendor marketplace. Vendors sign up through their own portal, list products, and fulfil their share of orders. VendorIQ splits multi-vendor orders, calculates commission, and shows what each vendor is owed. You choose and control the payout method; AI assistance for vetting, fraud, listings, and support is available according to your plan.
A Marketplace Is a Lot to Run by Hand
Adding sellers to a Shopify store means onboarding and vetting vendors, splitting orders with assigned seller products, chasing fulfilment, calculating commission, and managing payouts — 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
When a Shopify order arrives, VendorIQ groups products assigned to your vendors into separate order records and calculates each seller's share. When a vendor marks their items shipped, VendorIQ asks Shopify to create the matching fulfilment and tracking update.
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 and rule priorities so eligible vendor order lines use the matching commission rule.
Payout Workflows
Set a payout cadence, review vendor earnings after commission and holds, and use your connected Stripe or PayPal account where available. Bank transfers are manual and require your confirmation. Provider dispatch depends on your plan, setup, and the payout flow active for your store.
Approve Before It Goes Live
Set the review rules for new vendors, products, reviews, and questions. Keep manual approval where you need it, or use the specific auto-approval options your store enables; the merchant stays responsible for those choices.
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 inventory that syncs to your store, and fulfil orders with tracking. They can ask Shopify to send its standard shipping email when Shopify confirms the fulfillment.
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 can follow their sales and payout status, review observed low-stock signals, and refer other sellers. Demand projections appear only when enough verified order history is available.
A Marketplace Your Shoppers Can Browse
Publish vendor pages without custom code, then choose optional marketplace blocks in your Shopify theme editor.
Vendor Pages & Directory
One click publishes a public vendor directory and a shared profile page for eligible, approved vendors. A deep link helps you add the directory to your store navigation, and you can pin featured vendors. Unclaimed catalog imports stay private until the seller claims them.
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.
Help Shoppers Buy from Sellers Who Can Serve Them
VendorIQ now connects discovery, delivery promises, seller operations, and marketplace money in one flow. Turn on the parts that fit your store and let each vendor manage their own schedule.
Local Discovery & Delivery
Let a shopper check their area, find sellers who serve it, and choose an available delivery window or pickup point. Seller products check out with verified pickup or VendorIQ live delivery rates when your Shopify plan supports them; the setup view shows what still needs work.
Food & Grocery Workflows
Offer food and grocery in the same marketplace when your store needs both. Food sellers can publish menus with choices and serving times; grocery sellers can record picks, substitutions, shortages, and refund progress.
Clearer Daily Decisions
See vendor payables and money history, review changed listings and competing offers, and work through support cases and missing-order access requests. A guided setup view shows the next action for your store.
A branded shopper app can connect to these local-commerce services through Kernvel Mobile App Builder, currently available to a limited set of stores. Feature availability also depends on your VendorIQ edition, plan, and setup.
An AI Layer Across the Whole Marketplace
On eligible plans, optional AI assistance helps your team review sellers, spot order risk, improve listings, and handle support. Results depend on the data and features available to your store; your team keeps the final decision.
Vendor Vetting & Verification
On eligible plans, request an advisory AI risk score and business-document review while considering a vendor. The score helps your team decide; it does not admit a vendor on its own.
Order & Vendor Fraud Detection
On eligible plans, orders with the required verified data can receive an asynchronous risk score for staff review. Fulfillment and payout decisions use their own controls.
Listing Quality & Enhance
Eligible vendors can run a quality check on a listing for a score and concrete fixes, then use writing tools to improve its copy before review.
Product Demand Insights
Demand projections appear when enough reliable order history is available. The app shows when it cannot support a forecast; forecast-derived stockout and reorder advice is not currently available.
Commission Review
Review category activity and your current commission rules. Adaptive rate recommendations are paused until their results can be verified, so any change stays in your hands.
Dispute Assistant
For an eligible case with a verified shopper link and available AI provider, opening the dispute can surface a suggested resolution and draft replies. Your team makes the final call.
Availability varies by plan, store settings, source data, and release status. An unavailable insight is shown as unavailable rather than treated as a completed decision.
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, supplies the business details you require, chooses a supported payout method, and submits products. Your review settings determine when they are approved.
Orders Split & Fulfil
Orders with assigned vendor products split into seller shares. Each vendor can fulfill their part, and confirmed Shopify shipments can carry tracking into the shopper's normal order journey.
Payouts Run
VendorIQ shows eligible earnings after commission and holds. Review the payout and use an available provider flow, or send a bank transfer yourself and record its completion.
Your Store, Your Money, Your Control
You Never Custody Funds
Provider payouts use your connected Stripe or PayPal account where available; you send and confirm bank transfers yourself. VendorIQ records commission and payout states without holding merchant funds.
Shopify-Native & In Sync
Shoppers still pay through Shopify checkout. Vendor product and inventory edits sync to your Shopify catalog. Delivery, pickup, and service-fee options need their own setup; when a vendor marks items shipped, VendorIQ asks Shopify to create the fulfilment and can send the standard tracking email.
Scoped Access & Privacy Workflows
Merchant, vendor, shopper, and connected-app routes use separate access checks. VendorIQ handles the buyer details needed for marketplace orders, and its app data follows Shopify's required privacy-request workflows.
