Before this, I was keeping half my inventory notes in spreadsheets and still somehow missing things. The low stock alerts have been reliable, and the vendor and tag filters save me a ton of sorting. The scheduled reports give our team a regular snapshot, and I like that we can send alerts to different people depending on the location. I’d like a bit more control over the report columns, though, an...

Having separate alerts for each location has saved me from chasing people down for updates. The scheduled reports are handy too, especially when I want a quick idea of what needs attention before Monday.
— Stonevault Art
I mostly use the low stock alerts and filters, and both have been a big help. I can narrow things down by SKU instead of digging through the whole catalog, and the Slack notifications reach our team much faster than email. I just wish the CSV reports were a little easier to read on my phone.

Finally stopped checking stock every hour. The alerts have made keeping up with inventory so much less stressful.

Setting rules by collection saved me from doing this product by product, we carry over 2000 skus. Alerts hit fast, usually before the customer service inbox tells me. Two asks for Restock Lab. Let us pause everything during a flash sale, and let thresholds change by season, summer is nothing like december for us.

Ran the Out of Stock Lab inventory report against a physical count last month and the numbers matched on all but two items. The CSV drops straight into our sheet with no cleanup. Thats all I wanted.

My dad started this shop since a while and we still run it the same way mostly, this time it is online. Getting all our reorder points in at once with the spreadsheet upload took an afternoon instead of the week I was dreading. Marco in the back gets the OOS Restock Labs emails now so Im not the botleneck anymore. The sales report also settled an arguement weve had for years about which color actu...

I am not a computer person, my nephew set OOS up for me. What I like is the message comes to WhatsApp same as everyone else who talks to me, so I dont have to remember another login. It tells me plainly which item and how many are left. A short weekly summary would be welcome.

switched Stock Alert Restock Lab to one digest at 9am instead of pings all day. so much beter now
— Foragefuel Energy
Long time lurker, first review. The forecasting is what I keep coming back to, it flagged my candle sales climbing three weeks before I noticed. I send the PDF to my business partner every friday and she reads it without asking me questions. Filtering by vendor cut a ton of noise. Exports show up on schedule. Two things for the Restock Labs folks, a longer history in the forecast, and a suggested...

I dont normally leave these. We hold stock in two warehouses and Restock Labs watches both, without me doing the math. Being able to set a different trigger number on each product is what i actually needed
— Lumenloft Shop
We pipe OOS Lab alerts into our #ops Slack channel so the whole buying team sees them at once. Rules go down to variant level too, our size 8s vanish way faster than everything else. Alerts land within a minute. one thing id ask for is a snooze button for stuff were running down on purpose.
— Emberkitchen Design
OOS pinged me about a bestseller at 4 units left. saved my weekend honestly
— Sablesteam Energy
Our purchasing lead and I both get the weekly report now which cut out a lot of back and forth. The forecast breakdown in the pdf makes our buying meetings quick since the numbers are already laid out.
— Groundform
Uploading all my thresholds in bulk instead of one by one was the moment I relaxed about this. The alerts have been dead reliable, nothing slips past. Couple of asks for down the road, a Discord option would suit my team better than Slack, and some saved templates for the reports would save me redoing the setup each time.
— Pawprovisions Art
Ive been in retail twenty odd years and I still hate doing reorder math by hand. This thing looks at my sales trend and tells me roughly how much to bring in which has been a huge help honstly. Handling both my shop and my pop up location from one screen is somthing I didnt know I needed. The alerts bend to whatever schedule suits me too. Only gripe is setting up the WhatsApp side took a few tries...
— BabyHugy
What I appreciate is how granular the filtering gets, I can set different rules per vendor and per collection instead of one blanket threshold. And the reorder figures it works out actually track with what I end up needing, so I trust them now. If they added a webhook that would seal it for me.
— AlmaLuxe Co
not much of a reviewer but this earned it. the second stock dips below my number an email hits my phone and I can act right then. no more finding out from an angry customer.
— Kilnclay Shop
saved my butt during our big sale, got the alert befor we ran dry on our best seller
— Coilnest
I run a little home goods shop with my sister and we both needed to see the warnings, so it sending to two of us was the first box ticked. Getting a WhatsApp when something dips low is perfect because im never at my desk. The monthly pdf reports are clean and my accountant loves them. Uploading my whole product list at once saved hours. Wish the mobile view was smoother, and honestly the price cou...
