GS1 Assistant (GTIN UPC EAN) vs SKU Manager | Fontainefor Shopify (2026)
GS1 Assistant (GTIN UPC EAN) and SKU Manager | Fontaine both address product identification on Shopify, but they cater to different needs. GS1 Assistant focuses specifically on managing GS1-issued barcodes (UPC, EAN, GTIN) from a registered GS1 company prefix. It streamlines the process of assigning, tracking, and validating these official barcodes, integrating with GS1 member organizations directly or providing exportable spreadsheets. In contrast, SKU Manager | Fontaine offers a broader solution for generating and managing SKUs and barcodes, including custom automation, duplicate detection, and formatting options. It is not tied to the GS1 system specifically and aims to simplify the creation and organization of product identifiers in general.
