Trunk ‑ Stock Sync & Bundling

After trying some other apps with horrible results and deleted inventory, we were referred to Trunk by a company that was assisting us with our Shopify website. We had so many problems getting accurate inventory between our in-store Square sales and our Shopify website that we’re ready to just “throw in the towel” completely! We’ve had Trunk for a few weeks now and so far it’s working great. Our inventory is staying accurate and it has given us one less thing to worry about.

We had been looking for a long time (years), to find an app that would manage our inventory across multiple retail and wholesale platforms. None offered anything close to the breadth and ease of Trunk. Installing it was super easy (though the "pro" version for creating bundles was not so easy, at least for me). It has been an incredible time saver for all. (My staff is thrilled.) The feature that we have come to appreciate most is that we can see and adjust our inventory in one place on the Trunk dashboard. There you can see which products exist on a particular platform, which are sold in sets or individuals, and also identify where there is a typo in a SKU or other error. There also is no limit to the number of platforms to link to (so far we have four.) We are hooked! And with the very affordable monthly fee, I'm sure we'll be using this well into the future. Can't wait to see what other products they come up with.

Great app for keeping inventory synced between Amazon and Ebay. We have been using it for years without any problems. James is quick to help with any questions and requests that may arise.

My 2019 review: Stock syncing is an absolute necessity for my business and I am delighted to say Trunk handles this with ease. It saves me so much time and stress, I was always worrying that I might over-sell but since using Trunk I have had no problems whatsoever. Support is always fast and friendly. 2023 update: Unfortunately I've started to experience a lot of stock syncing discrepancies over the last few weeks, leading to overselling stock that is out of stock. It's unfortunate as Trunk always did this better than the rest so I'm really disappointed. Hope it can be rectified soon but looking at other reviews it seems I'm not alone.

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 products because their app is screwing up my actual inventory counts.

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.

I have been looking for an app for really long time. It’s the best! It can connect stores, handel duplicates and manage my bundles.. Love it! Customer Service is also helpful.

When I first installed this app, it seemed to work great and it would be perfect for what we needed. Is it too good to be true? Then the problems came. I updated inventory on a product and then it would revert to restocked. I thought maybe I did something wrong so I fixed it. I then added stock for a different product and a customer asked me if it had sold out. It had not (had they not asked I would not have known this was happening!). So I look and all the items that I had updated with new inventory were not synced up. The problems first came to my attention on a Wednesday when I thought I had did something wrong. Who knows how long it actually started before that. I contacted Trunk Thursday and again Friday. They got back to me Friday evening saying that there was something wrong on Etsy's end. Except how could that be because Shopify was also coming in incorrect. I had provided screenshots. Either way, there seems to be no urgency. The entire weekend we're losing sales because items are showing out of stock and then we are receiving orders for items that are out of stock and I have to cancel orders. In all, we have 5 days (that I know of) where this app is not working properly. What a nightmare. I LOVE the idea of the app if it worked the way it was suppose to. I am disappointed that an issue that starts on a Wednesday is not even resolved by Sunday (and is still unresolved as I write this). For this reason, I can not confidently recommend this app.

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 issue we faced was inventory accuracy. With thousands of SKUs, Trunk repeatedly made mistakes when updating stock levels between stores. We dealt with frequent oversells and found in-stock items marked as unavailable. These errors weren’t just annoying — they hurt our bottom line and disrupted our operations. Fixing these issues required a lot of manual intervention, which completely defeats the purpose of using an automation tool in the first place. It’s been time-consuming, costly, and damaging to customer confidence. After giving it plenty of time and chances to improve, we’ve decided to walk away. If you’re managing a large catalog or multiple stores, be careful — this app might end up doing more harm than good.

We are utilizing this to track inventory across Etsy & Shopify, but I think we'll also explore other channels now too. The app is working great so far, and it's an incredibly powerful tool. The only reason I am giving it four stars instead of five is that, although this has been existence for a while apparently, the user feedback that they implement seems to be done slowly or not at all. There are a LOT of things that can be improved for user experience. Here are a several things I think it is missing, from only a short amount of time using it: - Inventory adjustment history: It would be nice to see what has changed based on order IDs from the linked channel. This would pair well with an 'UNDO' button. - Sorting & filtering: Honestly, how is this not a feature yet? I want to be able to see items that do and do not have components, low stock, no stock, etc. As far as sorting goes, I don't understand it. My listings that have SKUs ending in 1, 2, 3, 4, 5 will be arranged at complete random. It's a headache trying to scroll up and down to find things. - Search Accuracy: Wow, it's bad. If I search a specific SKU, I don't want results for 50 others. Keywords is unusable in my opinion, it returns 50% of the items in our store. - Bulk Editing: I spent HOURS adding components, updating stock levels, and setting alerts. You have to do it one item at a time. It is so click intensive that after 3 long days of working on this, I woke up with pain in two of my fingers. While you can contact them to get a CSV for stock levels, their response times are quite slow so by the time it gets updated... It will be wrong. - Components with Multiple SKUs: Ah, this one is really awful. We have ~200 SKUs that have more than 1 'component'. I have to manually enter every component over and over, even though the items I'm adjusting are nearly identical. If you just utilized commas and auto-populated exact matches it would save so much time! Components: EXAMPLE1, EXAMPLE2 - No need to click add on each one, they are exact matches. I'm dreading the last bit of inventory management because of this. - Inventory Categorization: I think this is somewhat based on parts of the SKU such as PRODUCT-STYLE-COLOR, but it will categorize similar items as PRODUCT-STYLE-#####. My problem is that items are not being correctly categorized. They're grouped incorrectly, or not at all. That makes for more time of me searching to find which SKU didn't show up. - Master Inventory: Okay, we have components which is AWESOME. How do we not have an option for 'master' items? The majority of my components are based on multiple items (3 pieces, 5 pieces, etc.). Once these are set up with the 'master' (single piece) I don't need to constantly be seeing them. It causes the browser to load slower, and because of the sorting being all over the place, it takes me longer to find what I need to find. Fortunately if you set things up like us, you can just head to Shopify to make adjustments there. Nonetheless, being able to even star certain items or tag them (provided you add filters) would be huge. - Go to Listing/Inventory Item: Please add a button that allows you to click next to the item for each channel it is on. If I want to see my Red T-Shirt on Etsy, a button that will open a new tab and send me there would be convenient. It would help streamline necessary updates such as fixing duplicate or incorrect SKUs. - Low Stock Notifications: These are great. I'm not sure if they only send them one time once the item dips below the set alert, or if another is sold it will send the alert a second time (hopefully), but I really need a page that lets me see what is low. I'm a little worried that this isn't a current option. Again, filtering or a separate page would resolve this. - Items Per Page: I have to be honest here, I think it is a bit lazy your team hasn't added a simple dropdown menu to adjust the amount of items that show up on each page. I think the default is 12, which takes up only 50% of my screen. I had to make a script that automatically changes it to 25 any time I visit the website. This isn't a huge deal, but I cannot imagine implementing this would take your team much time. If I remember correctly, this was a suggested feature over 5 years ago that still hasn't been implemented. - Export/Import/Update by CSV: This would be a really excellent feature. Speed up making changes, easily search through listings for low inventory, keeping track of active inventory, allowing back-dating in case there was an issue. All this being said, I'm impressed with the app and will gladly pay for it until a better option comes my way, or these changes are implemented. They've done a great job thus far.

Great experience using Trunk. Very simple & user friendly!

I've tested out a few other 'inventory sync' apps before and Trunk does the job. We sell physically in two stores, Shopify and other sales channels, so we needed an app to sync all inventory to prevent overselling. The trial period allowed me to experience the app as is, and now in the first month of subscription, I can say that our inventory syncs so well, between sales made in our stores and online. It's truly a life-saving app, and James is quick to respond if you ever have any issues or questions!

I used to spend hours manually updating my inventory in Shopify whenever we had sales come in via our other channels. This not only took up so much time, but there was always room for human error. Trunk seamlessly integrates with the other sites, and reduces inventory whenever a sale occurs. On top of that - the support team is AMAZING. You really feel as though they want you to success, vs. an app that is installed and done. Probably my favourite app I've installed to date for both time saving and customer service.

Trunk does exactly what it says it will do and does it in actual "real time." I have been using Stitch for 5 years, and over the past 2 years I have trialed (for up to 3 months each) almost all of the other big players in inventory management software, and none of them sync between channels as fast as Trunk does. The interface is visually very nice to work with, and that is a welcome improvement over most of the other similar apps out there, which feel like you've gone back in time to the Internet circa 1998 - 2002. Well done Trunk! Please keep adding more functionality!

Trunk was exactly what I was looking for. It has helped me seamlessly keep track my inventory on both our retail and wholesale shopify websites, as well as our Faire brand account! It has saved me time and headaches by having an awesome solution to my inventory problems. I wholesale by the pack on one of our platforms, and using their bundling feature helped me without having to make workarounds in that particular platform's inventory. I was able to let Trunk keep track of the individual units and the pre-packed amounts simultaneously, which created an easier inventory system for us overall.

Amazing! Did exactly what I needed with our inventory management. Very happy with this app and will continue to use it to sync between our multiple shopify accounts and our Faire account.

Trunk provides us with a solid solution to keeping track of inventory over multiple sites. It's been a lifesaver! So simple and they are super responsive to questions. A huge plus.

Trunk is just the solution I had been looking for linking my amazon handmade listings, my Shopify and my Etsy stores. It was easy to onboard and easy to understand.

What can I say, this is a very powerful and easy system to set up and use. Not had any problem at all with stock being updated. James has been amazing, very friendly and happy to help with anything. Its a refreshing change to be able to just leave a system and not have to worry if my stock is correct, it's always been perfect since using Trunk. I have tried so many other systems to do this work, but always had problems and support was not coming, So this is such a nice and refreshing change. Amazing, thanks to James for all you have done to help.

This is simply an amazing app. If you need to sync stock between stores/marketplaces & products this is 1 stop shop. I tried everything in Shopify store but no app comes close to this. Amazing support too. Recommend it without hesitation.
