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!

— Roxy Lane Design

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!

— Studio Boketto

REALLY excited to have been referred to Trunk. SUPER easy to set up and is smooth like butter. As a small business owner, we have to be nimble with how we operate and quick to solve problems! Trunk helped and we're super grateful!!

The best solution for us to manage inventory between two Shopify stores. Easy to install, fast support. Really recommend for stock management.

— Magiškas Paštas

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 li...

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

— AddPeace Studio

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 re...

Super impressed with Trunk so far. The tool is simple and easy to plug in and start using right away. Perfect for a small business! Their support team has been fantastic, answering questions quickly and helping me get everything set up smoothly.

— Oso Supply Co

Trunk has saved me so much time and generally made the process of running my business so much easier and I can’t imagine being without it. Thanks team Trunk!

— Lila.

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.

— Marked & Made

I have been trying to get a hold of the developer after the app removed 100's of units of products out of my inventory that are not duplicated or on any of my other sites. Very frustrated with no response Very frustrated that I am now spending hours manually fixing this issue instead of the company that caused the problem

— shopnomads

12.6.2025: This app is a nightmare if you're using Etsy and Shopify for managing inventory. I keep inventory in Shopify and Trunk keeps on making additional changes to inventory amounts after hard entering correct numbers. Support gets back to me when they feel like it. With the holidays, this is just a nightmare trying to keep track of what's sold and have had several issues with overselling pr...

— Must Be Monogrammed

18/11/25 I am following up because we still have not received any response, and the issue remains unresolved. At the moment we are still unable to access the Trunk Inventory app due to the Cloudflare error, and our Etsy channel remains disconnected. This is creating a serious delay in our daily operations, as we cannot synchronize inventory or fulfill orders properly. We deeply appreciate your w...

After using it for 5 years it crashed completly. Put things in stock that were out of stock for months and vice versa. Created massive disruption, had to stock count over 30k pieces. Support blames etsy. Closed etsy connection and chaos still ongoing. Such a shame, moving to a more reliable app before I lose my amazon prime over so much overselling.

— DreamBuy.co.uk

We really wanted Trunk to be the answer for syncing inventory between our Shopify stores, but unfortunately, it ended up creating more problems than it solved. At first, it seemed like a solid tool, but over time it became a constant headache. The monthly subscription price kept creeping up, which might have been manageable if the software actually worked as expected — but it didn’t. The biggest...

— Fusion Scale Hobbies

AVOID, AVOID, AVOID! We made the switch to Trunk this month and within 2 weeks the system has COMPLETELY CRASHED, leaving no stock link with any of our platforms so with every sale our stock solution is TRASHED. I have tried contacting Trunk but have RECEIVED NO RESPONSE - There is no backup, and no proper support and as such, it is far too much of a risk to use this service.

— Sportandleisure.com

Really useful app for managing our inventory. It made it much easier to track kits properly and gave us a clear view of what was actually in stock at any time. One of the biggest improvements for us was eliminating duplicate entries, which used to create a lot of confusion. Overall, it brought much more structure and accuracy to our inventory management.

— VEDIC LAB

Trunk has been an essential tool in allowing us to expand our inventory across multiple sales channels without have to keep track of seperate stock levels. Very pleased with the team and the service we have received.
