Amazon Variations Are Painful
Flat file errors
Wrong variation theme, missing columns, Error 8007, Error 1876... Your upload keeps getting rejected.
Broken parent-child
Your variations split into separate listings. Reviews scattered. Sales velocity destroyed.
Category confusion
Every category has different rules, different templates, different required fields. It changes constantly.
Deprecated themes
Amazon removed hundreds of variation themes in 2025. Existing listings broke overnight.

Frequently Asked Questions
What is a flat file?
A flat file is an Excel/CSV template provided by Amazon to create or update product listings in bulk. It's the most reliable way to set up parent-child variation relationships.
What information do you need from me?
We need your child ASINs (or product details if creating new listings), the variation type (size, color, style, etc.), and which marketplace you're selling on.
How long does it take?
Standard orders are delivered within 48 hours. Professional and Enterprise orders get 24-hour priority delivery.
What if the upload doesn't work?
We revise the file until it works — at no extra cost. Amazon flat files can sometimes require adjustments based on category-specific rules, and we handle all of that for you.
Do you need access to my Seller Central account?
No. We provide you with the completed flat file, and you upload it yourself. Your account stays secure.
Which marketplaces do you support?
All Amazon marketplaces worldwide: US, UK, Germany, France, Italy, Spain, Canada, Australia, Japan, and more.
