The problem

Shopify gives you sales data. It doesn't tell you what to do with it.

Most Shopify sellers are making reorder decisions based on gut feel, spreadsheets, or last month’s numbers. That’s how stockouts and overbuying happen.

Stockouts on your best sellers

Your fastest-moving products run out before your next PO arrives. You lose sales, rank, and customer trust — and it’s nearly impossible to catch up during peak season when you need it most.

Cash tied up in slow movers

Overbuying on the wrong SKUs locks up working capital in inventory that sits for months. Every dollar in dead stock is a dollar you can’t use to grow the rest of your catalog.

Spreadsheets that don't scale

Manual reorder point tracking works for 20 SKUs. At 200 or 2,000 it breaks down. Seasonality, lead time changes, and promotions make it impossible to keep up manually.

No visibility across locations

If you’re selling across multiple Shopify locations or warehouses, knowing your true available inventory requires more than Shopify’s native reporting gives you.

FAQ

Common questions from Shopify sellers.

How long does it take to connect my Shopify store?

Most stores connect in under 4 minutes. Install IO from the Shopify App Store or connect directly from the IO dashboard — your sales history, product catalog, and inventory levels sync automatically. No spreadsheet imports or manual data entry required.

Does it work if I sell on multiple channels, not just Shopify?

Yes. Inventory Optimizer supports multi-channel selling. Connect Shopify alongside Amazon Seller Central, Amazon AWD, ShipStation, and QuickBooks so all your demand data rolls up into one unified forecast. Your Shopify sales are never modeled in isolation.

What if I have hundreds of SKUs and variants?

IO is built for catalog scale. It runs 100+ forecasting models per SKU and automatically selects the most accurate one for each product's unique sales pattern — whether you have 50 SKUs or 5,000. Variant-level forecasting is fully supported.

Do I need to know anything about forecasting to use it?

No. IO handles all the modeling automatically. You don't need to configure models, set parameters, or understand statistics. You see the output — reorder dates, order quantities, and stockout alerts — not the math behind it.

Does Inventory Optimizer work with multiple Shopify locations?

Yes. All Shopify locations are supported including storefronts, warehouses, and 3PLs. IO gives you cross-location stock visibility and flags when inventory is imbalanced across locations so you can make smarter transfer and reorder decisions.

How is this different from Shopify's built-in inventory tools?

Shopify's native tools track what you have. IO tells you what you'll need — and when to order it. It adds 12-month demand forecasting, supplier lead time awareness, automatic PO generation, and multi-channel demand blending that Shopify doesn't provide out of the box.

What happens after my 14-day free trial?

After your trial ends you'll be prompted to choose a plan starting at $79.95/month. There are no long-term contracts — everything is month-to-month. Cancel anytime with no fees or penalties.
