Supplier documents scattered across inboxes, a template per product type and per store, errors that say nothing useful. Evidale turns what you already have into what Amazon asks for — file in, file out, and without ever touching your Seller Central.
You send an inventory export and your documents. You get back files you can review and upload yourself — plus an archive that shows, per ASIN, where every piece of information came from.
The requirement is rarely the hard part. The data preparation is.
Four steps, all of them in writing. The pilot covers up to 50 ASINs on one marketplace, so you can judge the output before committing a catalogue.
A 5-minute written form. We confirm fit within 24 hours on business days — or tell you plainly it's not for us.
Scope, price and delivery date in one page. No upsell, no discovery calls.
Our checklist tells you exactly what to strip or mask before anything leaves your machine.
The full deliverable, plus one round of written Q&A included. Follow-up work only if you ask.
Handing over Seller Central credentials is a risk you should not have to take for a data job — and it is avoidable: everything we need travels as files, and everything we return travels as files you upload yourself. You stay the only party that ever touches your account.
We are a small independent studio and we don't ask you to take our word for anything. The sample is the real output, built on synthetic data — read it before you write to us.
The actual outputs for a fictional EU seller — missing-data matrix per ASIN and marketplace, a corrected upload-ready flat file, and the indexed evidence archive with its manifest.
See the sample outputsSellers who have their Responsible Person sorted often get stuck immediately afterwards — not on the obligation, but on getting the details onto the listings.
That second half is all we do. If your clients ask you for it, a plain written referral works both ways: they come to us for the listing data, and anyone who reaches us without a Responsible Person goes to you. No exclusivity, no fees, nothing to sign up for.
Send us the shape of the problem — how many ASINs, which marketplaces, what Amazon is telling you. Five minutes, in writing, no obligation, and a plain answer either way.
