Sell on Tesco Marketplace
Straight Out of Shopify
Commercium connects your Shopify store to Tesco Marketplace on tesco.com, now running on Mirakl, and runs the day-to-day operation: live stock from your Shopify locations pushed to your Tesco offers, Tesco orders accepted and created as tagged Shopify orders, and carrier codes and tracking sent back the moment you fulfil.
No credit card required. Onboarding takes 1–2 hours once your details are provided.
How Shopify and Tesco connect
Commercium sits in the middle, keeping stock, orders and shipments in step between the two.
What Commercium automates
Inventory sync
Shopify → Tesco
Available quantity from the Shopify locations you pick is pooled, buffered and pushed to every matching Tesco offer, so a sale on any channel updates tesco.com within minutes.
Order sync
Tesco → Shopify
Tesco orders are accepted on Mirakl against live stock and land in Shopify as native orders, tagged Tesco, with customer notifications suppressed.
Shipment sync
Shopify → Tesco
When you fulfil in Shopify, the carrier is mapped to a Tesco carrier code, tracking is sent and the order is confirmed as shipped on Tesco.
Need a flow that is not listed?
Extra locations, another Mirakl marketplace or routing Tesco orders to your 3PL or ERP are set up during onboarding.
Talk to usFrom demo to a live Tesco channel on Shopify
Seven steps from the first conversation to a controlled go-live: your Tesco Mirakl API key, Shopify and Tesco connections, SKU matching, stock, order and carrier configuration, then a verified test before you go live.
Book a demo & scope the setup
Tell us how you sell on Tesco today, how your Shopify store is set up, and how orders should reach your team. We walk through the integration on a live call and show you how Shopify and Tesco will work together on Mirakl.
Get your Tesco Mirakl API key
The Tesco Marketplace runs on Mirakl, so the integration runs on your Mirakl shop. We help you confirm the shop is approved and live, and generate the API key Commercium uses to update stock, read orders and send shipments.
Log in to the Commercium portal
You get access to the Commercium portal, where connections, mappings, sync logs and alerts live for both platforms.
Connect Shopify in Commercium
Commercium connects to Shopify through our Shopify App Store app or with Admin API credentials from a custom app you create.
Connect Tesco with Commercium
Your Tesco Mirakl shop is linked so Commercium can keep offer stock up to date, download orders and send tracking.
Configure stock, order & shipment rules
We map how each record moves between the two platforms so your warehouse team sees exactly what they expect.
Test, verify & go live
Every flow is run on real data before switching on: a stock change pushed, a test order accepted and imported, then fulfilled with tracking visible on Tesco.
Shopify and Tesco, and what connecting them actually involves
One is your store: products, stock and your direct-to-consumer orders. The other is Britain’s largest grocer, whose curated tesco.com marketplace moved onto Mirakl in late 2025 and only lists sellers Tesco has chosen. The work of the combo sits in between.

Seller API behind Tesco Marketplace
Shopify
Your storefront & stock source
Shopify is the hosted commerce platform behind millions of stores, from single-brand D2C sites to Shopify Plus enterprises. Products live as products with variants, stock is tracked as inventory levels per location, orders carry fulfilments and returns, and everything is reachable through the Admin API. For sellers moving onto Tesco, it is already the cleanest stock and order system they own, which makes it the natural engine for a marketplace channel.
Tesco
UK grocery-led general merchandise marketplace
Tesco is the UK’s largest supermarket group. It opened Tesco Marketplace on tesco.com in June 2024 to add third-party ranges in general merchandise alongside the weekly shop, and moved the marketplace from its original platform to Mirakl in late 2025, migrating existing sellers and their product data into the Mirakl catalogue. Entry is by Tesco’s selection, sellers are UK-registered businesses, Tesco takes customer payment, and every marketplace order is delivered by the seller by post or courier.
What we’ve learned integrating Mirakl for our users
Notes from live Mirakl operations across retail and B2B operators, and how each lesson became automation inside Commercium.
Acceptance windows decide your account health
Mirakl orders sit in a waiting-acceptance state and are auto-cancelled if you miss the operator’s window, which can be shorter than a working day. Acceptance and late-shipment rates then feed the operator’s seller scorecard. Commercium helps sellers:
Every operator is a separate integration wearing the same API
Sellers expect “we already support Mirakl” to mean plug-and-play. In practice each operator brings a different instance URL, API key, category tree, attribute set, value lists and carrier list. The API calls are familiar; the mapping is new every time. We keep mapping as reusable per-operator configuration so onboarding a new marketplace is days of setup, not another build.
Most rejections are value-list problems, not data-quality problems
Your catalogue can be perfectly clean and still be refused: the operator wants “Navy” where you send “Navy Blue”, a mandatory attribute exists only in that category, an image must be reachable at a public URL, or an identifier type isn’t accepted. Because imports are asynchronous, you only find out after polling the import and reading the error report. Commercium has built depth in:
Full feeds are expensive; deltas are fragile
Operators throttle imports and large full-catalogue pushes crowd out urgent price and stock updates. We run incremental offer updates on a fast cycle and reserve full reconciliation passes for a scheduled window.
Carrier codes are per-operator, not universal
Submitting a tracking number with a carrier code the operator doesn’t recognise means the shopper never sees tracking, and you get the contact. Each operator gets its own carrier and shipping-type mapping table.
Settlement only reconciles per operator
Commission rates differ by category and operator, refunds and adjustments land in transaction logs at different times. We pull logs per instance and match them back to orders before anything reaches accounting.
Same brand, different country, different rules
An operator running several country marketplaces often has separate instances, currencies, tax handling, language requirements and lead times. We treat each as its own connection with shared source data.
Onboarding is a data project, not an API project
Most of the elapsed time on a first Mirakl go-live is catalogue readiness, attributes, media, identifiers, not authentication. We front-load a data audit so approval isn’t blocked by rejected products.
KPIs quietly gate your growth
Acceptance rate, late-shipment rate, cancellation rate and message response time influence visibility and account standing. We monitor them per operator and raise them as operational alerts, not monthly reports.
B2B orders arrive with a VAT invoice obligation
Many Mirakl operators run B2B alongside consumer sales, and those orders require a VAT invoice to be uploaded back to the operator before the order can settle cleanly. Commercium identifies B2B orders automatically and handles the VAT invoice upload for them, so finance is not chasing marketplace portals by hand.
Tax-inclusive or tax-exclusive is never one answer
When orders are written into Shopify or an ERP, some businesses need totals tax-inclusive and others need them exclusive, get it wrong and every downstream report is off. Commercium transforms order totals to tax-inclusive or tax-exclusive according to each customer’s preferred setting.
Working notes from our integration team, we update this section as operator requirements change.

You can connect and manage multiple sales channels through a single Commercium subscription without purchasing a separate connector for each platform. Some enterprise and ERP integrations may require a higher-tier plan.
Does every order I receive on any channel get counted against my plan order limit?
For example, if you already sell through Shopify and use Commercium to connect three additional marketplaces, only orders received from those three marketplaces count toward your Commercium order limit. Your existing Shopify orders are not counted unless Shopify is also connected to Commercium as a sales channel for order processing.
Most supported platforms can be added without a separate per-connector fee, provided they are covered by your current plan category.

What happens when I cross my plan limit?
You can also upgrade to a higher plan if you consistently exceed your plan limits, as higher-volume plans can cost less.

This allows you to send orders for fulfilment and synchronize shipment and tracking information with your connected sales channels.
Can I connect my ERP and accounting software with Commercium?
These integrations can synchronize products, inventory, pricing, orders, fulfilment information, and accounting data, depending on the capabilities of each connected system.
What kind of support does Commercium offer?
The support channels and service levels available may vary by plan.
Why are there three different types of pricing plans?
Ecommerce pricing applies when your setup includes only platforms classified as standard ecommerce integrations.
Enterprise pricing applies when your setup includes an enterprise marketplace, retailer, fulfilment network, or another platform classified as an enterprise integration.
ERP pricing applies when your setup includes an ERP system such as Business Central, Odoo, Acumatica, or NetSuite.
If your setup includes an Enterprise or ERP integration, the corresponding pricing category will apply. Our team can review your requirements and confirm the appropriate plan before you subscribe.
Connect through the Commercium app on the Shopify App Store, or with Admin API credentials you approve, plus your Tesco Mirakl shop API key. Shopify stays the source of truth for stock, and every flow is tested on real data before anything goes live.
