I built a simple tool to stop wasting ad money on out-of-stock items. Looking for feedback

Hey everyone,

Like a lot of e-commerce/marketing folks, I’ve always been frustrated by one of the dumbest problems: burning ad money on products that just went out of stock.

I was sick of manually pausing campaigns every morning (and still missing things on weekends), so I built a tool for myself.

It’s pretty simple: it just connects to your store (Shopify, Woo, etc.) and automatically pauses your Google & Facebook ad campaigns the instant an item’s inventory hits zero.

It’s been working really well for me, and I’m curious if this is a “real” problem for other people, too.

I’m looking for 10-15 people to test it out as a beta user.

The deal is simple: You get to use it completely free. In return, I’d just ask for your honest feedback on what’s broken, what’s missing, and whether it’s actually useful.

If you’re running ads and want to give it a spin, just comment “interested” below and I’ll send you a DM with the details.

(P.S. This isn’t a “free trial” trick or a sales pitch. Just a builder looking to see if this thing I made can help others.)

Yes @FaresGM !

Thanks for sharing! This is definitely a real problem that causes a lot of wasted ad spend. It is great to see a dedicated solution for this! Manual checks might work for a few products, but as soon as a catalog scales, it becomes impossible to manage without automation. Good luck with the beta testing!

Interested, how can I access that?

This is a real problem. Merchant Center and Meta Catalog handle shopping ads, but regular product campaigns can keep spending because feed sync doesn’t touch them

The tricky part is pausing at the variant level, only resuming ads your app paused and not pausing everything on the first sync

I built AdStockGuard after running into this exact issue while building for Shopify. Happy to answer webhook questions if it’s helpful
