Reviews summary

The GS1 Assistant app has received overwhelmingly positive reviews from users. Customers praise the app for its excellent support, time-saving features, and ease of use. The app is particularly helpful for businesses managing large product catalogs with complex inventory structures and those needing to stay GS1 compliant. Users appreciate the developer's responsiveness to feedback and continuous improvement of the product. The app streamlines the process of assigning and managing GTINs, EANs, UPCs, and GS1 prefixes directly from Shopify, reducing manual work significantly. However, there is one negative review mentioning performance issues with larger product lists, where the system becomes extremely slow and non-functional after a certain number of GTINs.

Excellent app and outstanding support. We run a Shopify store with more than 20,000 SKUs and manage our own GS1 Norway company prefix. Before finding GS1 Assistant, our workflow relied heavily on manual Excel spreadsheets, GS1 imports, and countless hours of administrative work. From the very first email, Brian was incredibly responsive and helpful. He took the time to understand our unique business model, where a single retro game can exist in multiple variants and conditions, each requiring its own GTIN. Not only did he answer every question thoroughly, but he also implemented support for the GS1 Norway import format specifically to help us streamline our workflow. Throughout the process, communication was excellent. We received direct assistance, onboarding guidance, troubleshooting help, and even new features based on our feedback. When we encountered challenges, they were addressed quickly and professionally. The app now allows us to assign and manage GTINs directly from Shopify while dramatically reducing the amount of manual work required. For businesses handling large product catalogs, especially those using GS1 prefixes and complex inventory structures, this app is a huge time saver. What impressed us most was that the developer genuinely listened to customer feedback and continuously improved the product during our implementation. Highly recommended for any Shopify merchant who needs professional GTIN, EAN, UPC, and GS1 management. Easy to use, excellent support, and a developer who truly cares about customer success.

Thank you so much for the thoughtful review and for sharing your experience. Working with your team to streamline GTIN management for such a large catalog has been incredibly rewarding. I'm especially glad we were able to adapt the app to fit your workflow, including support for the GS1 Norway import format, and help reduce the amount of manual work involved. Supporting merchants with complex GS1 and GTIN requirements is exactly why we built GS1 Assistant. So it's great to hear the app is making a real difference for your business. Thank you for your feedback, collaboration, and trust throughout the process. – Brian

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!

Hey, thanks so much for the kind words! Really glad the app has been making GS1 code management easier for you, especially coming in without much prior experience with EANs and GTINs. That stuff can genuinely feel overwhelming at first. I'll pass your shoutout along to the rest of the team too. If you ever get stuck or need a hand with anything, just reach out. Thanks again for recommending us! Brian
