Trunk ‑ Stock Sync & Bundling

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.

Trunk is a fantastic tool for all sorts of bundles and inventory management. It has allowed us to bundle products together, whether it be a combination of items or multiple quantities of items, and it keeps our inventory numbers perfectly accurate. Its real-time updates make working with it very efficient. I would highly recommend Trunk if you ever want to group multiple SKUs together and not have inventory headaches.

Running an online cigar store means juggling inventory for singles, 5-packs, samplers, and full boxes, and before Trunk, that was a logistical mess. Trunk made it simple. The real-time kitting and inventory syncing has completely streamlined how we manage stock across products that share the same underlying units. What really stands out to me, though, is the support. The Trunk team is incredibly responsive; every time we’ve had a question or needed clarification, they’ve been quick to reply and genuinely helpful. It’s clear they care about making their platform work for your business. If you're in eCommerce and dealing with kitting or bundling, Trunk is one of those rare tools that actually delivers on what it promises.

Trunk has been a game‑changer for our business. We sell vintage toys on Shopify, Etsy, and eBay, and keeping inventory accurate across all three platforms was always a challenge. With Trunk, everything stays perfectly synced, which means we can focus on selling instead of worrying about overselling or constant manual updates. It’s simple, reliable, and an absolute essential for running multiple eCommerce platforms. Honestly, our business wouldn’t be nearly as successful without it. We highly recommend Trunk, it's definitely worth the money!

Trunk is a game-changer! I no longer have to worry about updating inventory manually across multiple platforms. I love being able to see all my listings in one place—it makes it so much easier to stay organized and avoid missing anything.

This is one of the most functional products that streamlines our entire business and removed a hefty weight from our team. Easily the best money I've spent this year for productivity. Trunk team was able to sync all my Square inventory across 12 locations forcing it to act as one centralized inventory overcoming a massive hurdle that Square seems to continuously ignore for small mobile locations. This has been an absolute game-changer! Now, a customer can place an order at one location for pickup on our next day at that site and Trunk overwrites my inventory at ALL OTHER LOCATIONS so that I don't oversell what we actually truly have in stock for the week.

On top of that, their team is AMAZING to work with. Solutions oriented, good listeners and designers to implement something that didn't natively exist. WHO does that anymore!? I was treated like a valued customer with respect and responsiveness. Couldn't love this product or team more!

At first, we couldn’t believe an app could handle inventory syncing this quickly. There's a lot of hype and empty promises out there, but very few tools actually deliver. After reading the overwhelmingly positive feedback, we decided to give it a try - and we’re glad we did.

Trunk works exactly as advertised. Inventory is synchronized almost instantly, and connecting our marketplaces was straightforward. So far, we have nothing to complain about. Trunk saves us a lot of time and gives us a much clearer overview of our entire product range.

Trunk is absolutely amazing solution for inventory tracking. We have Etsy and Shopify store with thousands of gemstones, that is impossible to truck manually. Trunk is easy to install, sync everything, even tells us duplicated SKU! And always received 5 stars help support from Arturo. Highly recommend!

Trunk has been a game-changer for us! It seamlessly integrates our Shopify and Square accounts, making it easy to sell in-store and online while managing inventory across multiple platforms. It’s opened up new expansion opportunities for our business and saved us tons of time!

Trunk is the only app I’ve come across that actually handles bundled / kit/ parent products effectively. Gives the ability to accurately keep stock the website & marketplaces using a parent sku has made life so much easier! Thanks James!
