Mirakl Integration for Marketplace Sellers

9 October 2026

Mirakl is the technology behind many retailer-run marketplaces. If you sell on a retailer's marketplace rather than a standalone one, there is a good chance Mirakl is what connects your catalogue and orders to that retailer. A Mirakl integration lets another tool read those orders and costs automatically.

Why Mirakl marketplaces need their own attention

Each retailer sets its own commission, categories and rules, even though they share the same platform. Selling on three Mirakl marketplaces can mean three different commission rates, and the sales total in each seller account will not show you what you kept.

What a good Mirakl integration should give you

  • Orders from every connected Mirakl marketplace in one place
  • Commission taken from each order, at its actual rate
  • Shipping and fulfilment costs matched to the sale
  • Refunds and returns charged back to the right product
  • Profit per SKU and per marketplace, side by side

Mirakl and the rest of your stack

Many sellers also run ERP or accounting systems alongside their marketplaces. The cleaner your product and cost data is in those systems, the easier it is to get accurate profit from your marketplace orders. If you use a specific ERP and want to know how it fits, ask us and we will tell you honestly what is and is not supported.

How WhatSales works with Mirakl

An example

A seller lists one product on two Mirakl-powered retailers. One charges a lower commission and has cheaper bulky shipping, the other a higher commission. At the same shelf price, the profit per order differs. Looking at the two seller accounts separately hides it. One combined view shows it immediately.

What is Mirakl in simple terms?

It is software that lets a retailer run a marketplace where other sellers list products. Mirakl connects the retailer's site to sellers' catalogues, orders and shipping.

Do I need a separate integration per Mirakl marketplace?

You connect each marketplace account you have. WhatSales then shows them together.

Which Mirakl marketplaces does WhatSales support?

B&Q is covered on /integrations/b-and-q. For others, ask us and we will tell you what is supported today.

WhatSales connects to your Mirakl account and turns the order data into live profitability across every Mirakl marketplace you sell on. The page at /partners/mirakl explains the integration, and /integrations/b-and-q shows it applied to one specific retailer.
