Stop wasting ad spend on out-of-stock products

Features
Prevent out-of-stock ad waste
Monitor first. Automate when you're confident.
Real-time inventory monitoring
Tracks Shopify inventory via webhooks. Detects stock drops within seconds.
Automatic pause & resume
Pauses selected ads when stock drops below your threshold. Resumes when stock recovers.
Full audit log
Every action is logged with timestamps and reasons. Review what happened and when.
Safety-first controls
Only acts on ads you select. Never resumes manually paused ads. Kill switch available anytime.
If you spend $200/day and a product is OOS for 2 days, that's ~$400 of clicks that can't convert.
That's not a projection — it's math. SpendGuard catches these moments automatically.
The problem
Why not feeds or manual pausing?
Because stockouts don't wait — and brittle automation fails silently.
Manual pausing is too slow
Stockouts happen overnight and on weekends. By the time you notice, spend is gone.
Feed sync can lag
Feed updates and mapping aren’t always immediate. Delays can keep spend running on OOS items.
SpendGuard is selective and logged
You choose what’s protected. We pause/resume only at the level you select and log every action.
How it works
Three steps to protect your ad spend
Simple setup. Fully automated after that.
Choose what to protect
Select the ads you want SpendGuard to control and pick the products they depend on.
Set your stock rules
Set a pause threshold and a resume threshold. You stay in control — SpendGuard only acts on what you selected.
We pause, resume, and log everything
When stock drops, SpendGuard pauses those ads. When stock recovers, it resumes them — with a clear audit log of every action.
