Most Shopify merchants run inventory in a spreadsheet. They update it manually, miss sales because of stockouts, and don't know until it's too late. DaysOfStock connects to your Shopify store and tells you — in days — how long your stock will last. No manual updates. No surprises.

Most merchants have no idea how many days of stock they have at any given moment. DaysOfStock calculates your days-of-stock for each SKU using your sales velocity, so you always know when to reorder — and how much to buy.
| Product | Daily avg sales | Days left |
|---|---|---|
| Vitamin D3 Complex | 4.2/day | 11d |
| Protein Powder Vanilla 2lb | 2.8/day | 22d |
| Resistance Band Set | 8.1/day | 4d |
Running out of stock means lost sales and frustrated customers. DaysOfStock sends you an alert when a product's stock falls below your reorder threshold — giving you time to source and restock before you hit zero.
Your Shopify store is the source of truth — DaysOfStock keeps it that way. Every stock adjustment flows directly from your Shopify inventory. No duplicate data entry. No mismatched numbers. Just one view of your inventory across your entire store.
| Location | Products | Alerts |
|---|---|---|
| Main warehouse | 287 SKUs | All clear |
| Secondary warehouse | 64 SKUs | 2 warnings |
| Retail storefront | 112 SKUs | All clear |
I was running my whole inventory in Google Sheets. Every sale meant updating 50 rows manually. DaysOfStock connected to my store and I haven't touched a spreadsheet since.
I used to find out I was out of stock when customers emailed me. Now I see it coming 10 days in advance. It's saved me at least $2,000 in lost sales this quarter alone.
