Commerce data-consistency monitoring
Your catalog drifts.
Your customers notice before you do.
ShelfDrift watches your live storefront and checks every product back against your source of truth: price, stock, availability, images. When your systems stop agreeing, you hear it from ShelfDrift, not from a lost sale.
Exports fail quietly
You push products from your PIM out to your shop, your marketplaces, your ERP, and most of the time it just works. But when it does not, nothing tells you. A price update that never propagated. A product that has gone missing from the storefront. An item shown in stock that actually sold out last week. A photo that quietly broke. Each system only knows its own side, so no one is watching the gaps between them.
How it works
ShelfDrift sits outside your systems and compares them, the way an honest auditor would.
Connect your systems
Read-only, through each system's official API. ShelfDrift never touches your checkout or your customers' data.
ShelfDrift reads your live shop
Just the public pages, the same ones a shopper sees. No plugin to install, no export to configure.
ShelfDrift shows you the drift
Product by product, field by field, with every source side by side. You see exactly what disagrees.
One mismatch, in plain sight
This is the whole product: the same item, lined up across your systems, with every field that disagrees flagged.
| Field | PIM | ERP | Storefront | Status |
|---|---|---|---|---|
| price | €29.99 | €29.99 | €24.99 | mismatch |
| stock | 100 | 0 | 100 | mismatch |
| availability | in stock | in stock | in stock | match |
| image | ok | ok | ok | match |
What ShelfDrift checks
Presence
Every active product resolves to a live page. No silent disappearances.
Price
The price on the shelf matches the price in your system of record, down to the cent.
Availability and stock
In stock means in stock, in every system. Sold out means sold out.
Media
The product image actually loads, and it is the image it is supposed to be.
ShelfDrift sits between your systems, not inside them
Your PIM, ERP and DAM each own their slice of the truth, and they stay that way. ShelfDrift sits on the outside and confirms that what one system publishes is what the next one actually received: intact and current. It flags where systems disagree. It never decides who is right: that call is always yours.
The same product can carry its barcode in a different shape in every system: different lengths, stray characters, units that do not line up. Matching them reliably is the hard part, and it is the part I have spent my time on. When ShelfDrift reports a mismatch, it is a real mismatch, not a formatting quirk.
Looking for a first integration partner
ShelfDrift is brand new, and I am building it around one real catalog. If you sell online and run a PIM, ERP or DAM behind your storefront, I will run ShelfDrift against your products entirely free, in exchange for a bit of your time and the chance to learn from a real use case.
Read-only, always. ShelfDrift never changes anything in your systems: it only reads, compares and reports. You lend me API access and some feedback. You get a continuous integrity check on your catalog, at no cost.
