Frequently asked questions
What is a SKU in Shopify and how does SKUGen help?
A SKU in Shopify is a stock keeping unit, a unique code for each product and variant. SKUGen works as your Shopify SKU generator so you can define a clear pattern for SKU numbers, apply it across products and avoid messy spreadsheets.
Is there a free SKU generator plan I can start with?
Yes. The Free plan lets you generate simple SKUs for up to 100 products using a prefix, suffix, auto number and dash separator. You can also preview advanced options and print labels for one product at a time, or unlock Advanced options with a one time $9.95 fee when you are ready to scale.
Can SKUGen generate SKUs only for products that do not already have a SKU number?
Yes. When you run the generator you can enable the option to set only missing SKUs so existing codes are left untouched. In automatic SKU generation settings you can also tell SKUGen to fill SKUs only when the field is empty, or to overwrite them when you explicitly want to replace older codes.
How does automatic SKU generation work for new Shopify products?
With the Auto generation plan, SKUGen can generate SKUs automatically when you create or update a product in Shopify. It uses your last active template, runs in the background, can be restricted to products with a specific tag and lets you decide whether to overwrite SKUs on duplicated products.
Can SKUGen generate barcodes and product labels too, or only SKUs?
SKUGen can generate both. With Advanced options and Custom Codes you can create numeric codes that follow EAN and UPC rules, including automatic check digit calculation. With the Premium plan you can then print these as Code 128, EAN 13 or QR barcodes on product labels that you design with the label template editor.
Can SKUGen help find duplicate SKUs and barcodes in my catalog?
Yes. Starting with the Custom Codes plan, the duplicate checker scans all products and variants in your store and reports any duplicated SKUs or barcodes, even if they were not created by SKUGen. You can then regenerate new codes for only the affected variants.
Will SKUGen work for large catalogs with thousands of SKUs?
Yes. Only the Free plan is limited to 100 products. If you use Advanced options or any of the monthly plans, there is no limit to how many products you can process. Stores have already generated tens of thousands of SKUs in a single run with SKUGen.
Can I customize the SKU format with prefixes, options and my own codes?
Yes. You can build SKU layouts using prefix, suffix, product title abbreviation, options, product type, vendor and auto numbers. On the Custom Codes plan you can define your own abbreviations and special codes using tags or metafields so SKUGen becomes your custom sku generator and sku number maker, not a random sku generator.
If you are looking for a Shopify SKU generator or sku code generator that keeps product data consistent, SKUGen lets you generate SKU numbers from a single reusable template instead of building every code in a spreadsheet.
Start on the Free plan as your free sku generator for Shopify, then layer in automatic SKU generation, custom sku rules and barcode label printing as your catalog grows.
Ready to clean up your SKUs?
Install SKUGen, set up one template and let the app handle SKU and barcode work for every new product that hits your store.
