SKU Generator

About the SKU Generator

As a catalogue grows, inconsistent product codes become a nightmare — duplicate SKUs, unreadable strings, and no logic to tell products apart. A consistent SKU system makes inventory, picking and reporting far easier.

This SKU Generator creates consistent, scannable SKU codes in bulk from your product attributes, and lets you download them as a CSV ready for your store or spreadsheet.

How to use the SKU Generator

1. Enter your product attributes (like category, colour, size).
2. Choose your SKU format and separators.
3. Generate the SKUs in bulk.
4. Download them as a CSV.

Key features of the SKU Generator

• Generates consistent SKUs in bulk
• Built from your product attributes
• Scannable, readable codes
• CSV download
• Private — runs in your browser

How the SKU Generator works

These calculators use the standard, published fee structures of the major marketplaces and platforms — Shopify, Amazon FBA, Etsy and eBay — including referral, transaction, payment-processing and fulfilment fees. By combining those with your product cost and price, they show your real profit and margin per sale rather than just revenue.

All calculations run privately in your browser.

Tips & best practices

• Build meaning into the SKU — a short code for category, colour and size makes stock instantly recognisable.
• Keep SKUs a sensible length and avoid ambiguous characters like O and 0 to prevent picking errors.
• Never reuse a retired SKU for a different product, or your historical reports will be confused.

Standards & accuracy

Based on the published fee structures of Shopify, Amazon, Etsy and eBay for realistic seller estimates.

Marketplace fees vary by plan, category and country and change over time, so treat results as close estimates. Confirm the exact figures against your own seller account before making decisions.
