    I'm being investigated; I uninstalled the app months ago, and they're still charging me for not installing it.

    An Incredibly Helpful and Time-Saving Tool! The GS1 Assistant made working with GTINs and UPCs so much smoother and more intuitive. It takes the guesswork out of product identification and helps ensure everything is formatted and validated correctly. I was impressed by how quickly it provided accurate guidance, especially when managing large datasets. The interface is clean and user-friendly, and the step-by-step support is a huge plus. It's a must-have for anyone working with product barcodes or needing to stay GS1 compliant. Highly recommend!

    We have been using the app for a few months now and must say it is the best thing that is available for GS1 code management. We have no prior knowledge and the app makes its extremely easy to navigate the complex world of EANS, GTINS etc. Support is also 5 star. Special thank you to Brain, who is extremely is responsive and kind enough to arrange a call to help get through any difficulty. The app is very easy to use , and is money well spent for the price. Overall great experience and highly recommended. Thank you GS1 Team!

    GS1 Assistant is a must-have tool for any Shopify store managing UPC, EAN, or GTIN barcodes. It seamlessly integrates with your GS1 Company Prefix, ensuring accurate barcode assignments without duplicates. The app makes syncing with GS1 effortless, preventing errors and streamlining product management. The support team is amazing, quick to reply and detailed. Highly recommend this app!

    I needed urgently to create GTIN code to our older stock (600 SKU), which would else be a nightmare, since GS1 has changed its layout of the bulk upload files. This App saved me 2 days of work! So I do recommend it

    GS1 Assistant hat die Verwaltung von GTINs in unserem Shopify-Shop unglaublich einfach gemacht. Das Zuweisen von UPC/EAN-Codes ist unkompliziert, und die direkte Integration mit GS1 Germany spart enorm viel Zeit. Sobald ich EAN-Codes zuweise, werden unsere Produkte automatisch mit GS1 synchronisiert – einfacher geht es nicht ! Was diese App besonders auszeichnet, ist der hervorragende Support. Brian und sein Team sind äußerst reaktionsschnell und verbessern die App kontinuierlich basierend auf Nutzerfeedback. Es ist selten, eine App zu finden, die sowohl leistungsstark als auch einen super support bietet! Wenn Sie GS1 Germany nutzen oder einfach eine zuverlässige Möglichkeit zur Verwaltung von GTINs in Shopify benötigen, können wir GS1 Assistant nur wärmstens empfehlen!!!

    GS1 Assistant has made managing UPC codes effortless for our Shopify store. Assigning GTINs to products is simple, and the products appear in Verified by GS1 shortly after uploading to GS1. This means we don’t have to worry about issues with Amazon or Google Shopping—they work. The app is straightforward, reliable, and takes the stress out of synchronizing our Shopify products with GS1. The support team is incredibly helpful and responsive if you have questions. I highly recommend GS1 Assistant for anyone running a Shopify store!

    Absolut keine Empfehlung. Bei größeren Artikellisten ab ca. 18.000 Artikel bzw. Varianten wird alles extrem langsam. Ab ca. 20.000 vergebenen GTINs gibt das System seinen Geist auf und funktioniert gar nicht mehr. Nach anfänglicher Begeisterung bin ich absolut enttäuscht.
