What you get with this Offer
Product feeds are where marketplace launches go to die. Wrong category, a missing mandatory attribute, a malformed identifier, a variant structure the platform won't accept — and back comes an error file with 200 rows and no explanation of any of them.
I build feeds that upload cleanly, and I fix the ones that don't.
WHAT YOU GET
- Your product data mapped into the marketplace's own template, up to 15 SKUs
- Correct category selection and every mandatory attribute completed
- Identifiers, barcodes, variants and bundles structured the way the platform expects
- Upload, error triage and resubmission until the file goes through
- A clean master file you can reuse for every future upload
HOW IT ARRIVES
The completed template, uploaded and confirmed live, plus the master file and a short note on what was wrong and what I changed. If something has to be fixed on the marketplace's side rather than in the feed, I tell you that plainly instead of charging you to keep retrying.
WHO THIS IS FOR
- Sellers onboarding onto a new marketplace for the first time
- Anyone sitting on an error file they can't decode
- Brands whose catalogue went up half-complete and never got finished
WHY THE PLATFORM MATTERS
8+ years running live marketplace accounts across the UK and North America, including six Mirakl-based catalogues — the platform behind Tesco, Debenhams, B&Q, Best Buy Canada, Mountain Warehouse and BrandAlley. Also Frasers Group, Amazon, Walmart Canada, eBay and Etsy.
Every one of them validates differently. The same spreadsheet that sails through one marketplace is rejected by the next on a mandatory field the first didn't ask for. Error messages are often worse than useless — an image that simply took too long to fetch gets reported as an invalid file format, which sends people off re-encoding files that were fine all along. Knowing which errors mean what is most of the job.
WHAT I NEED FROM YOU
Your product data in whatever state it's in — spreadsheet, export, or a mess. Plus marketplace access or the blank template, and any error file you've already been sent.
Bigger catalogue? Message me first and I'll quote it properly rather than making you buy this five times over.
