We've had a great experience with Trunk. It handles bundling products with the same SKU in our Shopify store exactly as we needed, and the setup was simple. Their customer service is outstanding—responsive, knowledgeable, and always willing to help. Highly recommend!

Trunk has been an absolute game changer for my business. I update my inventory in ONE place, and it automatically filters across all of my channels. I wish I'd signed up years ago. If you're running a busy business, get this app now — it's your one-stop shop for keeping up with constantly changing inventory. It's worth every penny!

Love it! Does exactly what I want! Simple to use, no nonsense. syncs all inventory across all platforms live. Saves our business heaps of time! Best decision we made this year!

I used to manually manage my inventory over 3 separate websites. It was time consuming and also very daunting, Not to mention it would lead to inaccuracies across the different website inventories. We tried a couple different apps through Shopify to help none of them worked or didn’t work like we wanted them too. We tried Trunk out and as soon as we had it figured out and all site linked it was like magic. A change to one site and the sync happens at all sites linked. To change inventory on all site you only need to change it on any site you choose or through Trunk itself and the rest is automatically update. Solid app. Highly recommended

Trunk is taking hours of mental load from me by seamlessly tracking my inventory between Faire and Etsy.

The software is excellent. It successfully solved our biggest challenge: syncing our Amazon and Shopify inventories. The platform is easy to set up and use, and the customer service team is highly responsive. I would recommend it to anyone.

Trunk has been a great tool for linking my physical store system to my website, I trialed a few different apps to make this happen for us, but each one had certain flaws that meant it wasn't right for us, but Trunk was super quick and easy to use, does exactly what it says on the tin, no hoops to jump through, no long set up procedures, just really easy, simple functionality. I would definitely recommend!

Trunk has been an OUTSTANDING solution for my business. We have a bespoke use case, and syncing inventory between multiple channels and even multiple Shopify stores has been a challenge for us. Trunk simplified all of that into something that just works. Plus, support was there to help with some of my weird use cases! Definitely my new go to inventory management app.
