The review comes after the job, not after the delivery
A box of floor tiles delivered on Friday tells the buyer nothing except that the tiles arrived. Whether they were the right choice is answered a fortnight later, when they are down, grouted, and either look like the photo or do not.
DIY is project-shaped. The purchase is one step in something the buyer is building, and the useful review — the one that mentions that the colour is slightly warmer than it photographs, or that the adhesive recommended on the listing was wrong — can only be written from the far side of that project.
Ask on delivery and you get "arrived on time". Ask after the job and you get the review that sells forty more.
Bulky goods break the usual delivery assumptions
Building materials do not arrive by parcel courier. They arrive on pallets, on booked delivery slots, sometimes kerbside, sometimes with the buyer needing to be present. Delivery is a scheduled event rather than a doorstep drop, and it can slip.
That matters for automation because it makes dispatch an even worse trigger here than usual. The gap between "left the warehouse" and "actually with the customer" can be substantial, and a review request that lands in that gap is a request to review something the buyer is still waiting for. Reading the delivery event rather than the dispatch event is not a refinement in this category, it is the whole thing.
Trade buyers and consumers are not the same audience
A meaningful share of Leroy Merlin's buyers are tradespeople buying for a job, not householders buying for a weekend. A tradesperson's review is short, unsentimental and extremely persuasive to other tradespeople, because it speaks to durability and to whether the spec was honest.
They are also the buyers least likely to volunteer a review unprompted — they are working, not browsing. Asking is the only way you ever hear from them.
What Merita does
We take the delivery confirmation from your Leroy Merlin orders, allow for the fact that what was bought has to be installed before it can be judged, and send one message in the buyer's language through the marketplace's own buyer messaging. Nothing offered in return; complaints and open returns excluded automatically.
