Set it up yourself
Follow these 4 steps in order. You will need accounts for: Shopify.
Step 1: Connect inventory
- In Shopify custom app, enable read_inventory and read_products.
- Copy the token.
- In the workflow, poll inventory levels daily (or use a midnight schedule).
- Output: Product/Variant, Qty, Location.
- Test the read matches your store's actual stock.
Watch out: Include the location field — if you manage multiple warehouses, an alert without location is half a message.
Step 2: Set thresholds
- Create a sheet 'Stock Thresholds': Variant, Threshold (alert when ≤), Reorder Qty, Supplier.
- For products without a row, use a default threshold (e.g. 5).
- Review the thresholds with your ops knowledge.
- Set per-variant overrides for fast movers.
- Test by temporarily lowering a real product's threshold.
Watch out: Per-variant thresholds beat a global number — a bestseller should alert at 30, a slow mover at 3.
Step 3: Add the Slack alert
- Create the Slack incoming webhook to your #inventory channel.
- For each threshold crossing, post: product, variant, qty, suggested reorder.
- Include a link to the admin product page for one-click ordering.
- Rate-limit: one alert per variant per 24h.
- Test with the temporary lowered threshold.
Watch out: One alert per variant per day keeps the channel readable; a daily re-fire on the same SKU is noise.
Step 4: Schedule the check
- Run the inventory check daily at 8am.
- Add the weekly summary on Mondays: top 10 risk SKUs, weeks-of-stock estimates.
- Keep a 30-day inventory log to compute the velocity.
- Review the weekly summary in your ops sync.
- Update thresholds quarterly with new sales data.
Watch out: Weeks-of-stock (qty ÷ daily sales rate) is the metric that catches slow burners — warn on those too, not just zero.
