Preparing Your Flat File for Upload

Step 2: Fill in the Required Information

Once you've selected your template, you'll need to populate it with your product information. This includes:

  • SKU: A unique identifier for each product or variation.
  • Product Title: The name of your product.
  • Brand: The manufacturer or brand name.
  • Category: The specific category your product belongs to.
  • Price: The retail price of your product.
  • Inventory: The quantity of each product available for sale.

Step 3: Validate Your Flat File

FlatFilePro's built-in validation system will review your flat file for any errors or inconsistencies that could lead to listing problems on Amazon. Our software will flag any issues and provide guidance on how to correct them, ensuring your flat file is perfect before upload.
