Why B&Q margins are hard to track

One of the UK’s most visited home improvement sites, with fees that add up quietly.

B&Q’s Mirakl-powered marketplace gives UK sellers access to diy.com’s huge traffic and a trusted brand, but between commission, fulfilment costs and refunds, it’s easy to lose track of what a listing is actually worth. A sales total on its own doesn’t tell you what stayed.

Every B&Q order is reconstructed from its components: the price the buyer actually paid, so the starting number is the real one, not an estimate. WhatSales then deducts the costs that decide whether an order made money:

  • ✓Mirakl commission pulled from the order at its actual rate, not a flat estimate.
  • ✓Fulfilment & shipping, whether you handle it or a partner does.
  • ✓Ad spend behind the specific sale, not a blended average.
  • ✓Refunds and returns, allocated back to the SKU that was returned.
  • ✓Full order P&L, plus product-level economics for every SKU.

The result is an estimated profit and margin you can trust: the figure that reaches your bank, ready to sort, filter and trend across your whole catalogue.

True profit on every B&Q order, not a sales total. Mirakl commission, fulfilment costs and refunds all chip away at the same sale. WhatSales rebuilds each order from its raw parts, then applies the actual costs, to give you profit and margin per order and per SKU.

Sort by margin, filter by product, trend across the quarter: B&Q sits in one dashboard with Amazon, eBay and every other channel you connect, rather than in a Mirakl export you have to decode by hand. See /profitability for how the same calculation works across every channel.

Same £24.99 sale, three quiet deductions

Commission, fulfilment and ad spend all take a bite before you see a penny.

On the worked example above, commission, fulfilment and ad spend plus returns take almost 60% of the sale before cost of goods is even counted. WhatSales breaks that down on every single order, not just as a one-off example.

Mirakl Commission
15% of this £24.99 sale.
£3.75
Fulfilment

£4.20
Ad Spend + Returns

Three deductions, one sale: £10.95 gone before cost of goods is even counted. WhatSales tracks the real amount on every order, so nothing gets averaged away.

Everything you need

Everything you need to run B&Q, in one place.

↗

Performance

A listing can be getting plenty of traffic on B&Q and still be underperforming against what it should deliver after fees. Performance tracks sales trends, orders and refund rates on B&Q alongside every other channel, so you can tell what’s actually driving growth.

▢

Restock

A stockout on a well-performing B&Q listing doesn’t just lose the sale, it resets visibility once it’s back in stock. Restock flags low inventory automatically, before you run dry.

↻

Replan

Not every product deserves a second order, especially once commission and fulfilment are accounted for. Replan shows you which products are actually worth reordering, based on real sales and margin performance, not just what’s moving.

🚚

Sourcing

You know a product is selling on B&Q. What you don’t always know is whether your supplier can restock it in time to protect your listing. Sourcing tracks supplier lead times alongside your sales pace, so restocking decisions reflect real turnaround.

✉

Engage

Marketplace standing depends on fast responses and low unresolved-issue rates. Engage keeps every customer message and support ticket in one inbox, so nothing slips through.

◆

Workspace

Scaling on B&Q brings its own listing, content and compliance demands. Workspace takes on the listing copy, product imagery, variation and bundle setup, quality assurance and day-to-day support, so growth doesn’t cost you your week.

Questions

B&Q sellers ask

How does WhatSales calculate real profit on a B&Q order?+
Each order is rebuilt from its raw components: sale price, B&Q’s Mirakl commission, fulfilment cost and your product cost (COGS). WhatSales subtracts every one of those to show true net profit per order and per SKU.
Does WhatSales work with Mirakl-powered marketplaces beyond B&Q?+
Yes. WhatSales connects to the wider Mirakl ecosystem, so other Mirakl-powered marketplaces you sell on can be tracked and compared the same way.
How are B&Q refunds and returns handled?+
Refunds are tracked against the original order with a refund ratio and reasons surfaced, so a specific SKU quietly losing money to returns shows up before it eats into a month’s margin.
Can I compare B&Q against my other marketplaces?+
Yes. /profitability lines up the same SKU across every connected channel side by side, so you can see whether a product performs better on B&Q, Amazon, eBay or wherever else you sell it.
Can I manage my B&Q listings from WhatSales?+
Yes. /flow lets you create and update listings once and publish across B&Q and every other connected marketplace from one place, instead of managing each channel separately in Mirakl.
