Is Shopify Analytics accurate enough to base inventory reorder decisions on?

Yes for what it measures, but not on its own. Shopify Analytics reports stock on hand and units sold per day accurately, yet it has no lead time, safety stock, or reorder point. Its data can lag 12 to 72 hours, so treat it as one input to reorder decisions.

What the native numbers cover

Shopify’s Days of inventory remaining divides ending quantity by average units sold per day. The default Inventory remaining report calculates that daily rate from the last 28 days. The Average inventory sold per day report uses whatever date range you select, which makes it the better place to check velocity for seasonal products, where a 28-day window can make stock look far healthier than it is heading into a peak.

What a reorder decision needs that Shopify doesn’t provide

A reorder point is calculated as:

Reorder point = (Daily sales velocity × Lead time) + Safety stock

Shopify supplies only the first input. The gaps:

• Lead time: supplier lead time isn’t stored anywhere in Shopify’s reports.
• Safety stock: there is no buffer setting or column.
• Incoming stock: Days of inventory remaining counts stock on hand only, so units already on an incoming transfer don’t push the reorder date back.
• Reporting delay: inventory changes can take 12 to 72 hours to show in reports, which matters most during sales events.

When the native view is enough, and when it isn’t

A store with one location, steady demand, short supplier lead times, and a catalog small enough to review weekly can usually reorder from Days of inventory remaining alone. Seasonal catalogs, lead times of several weeks, multiple warehouses, and large SKU counts are where the missing inputs start causing late or oversized orders.

Closing the gap

This is where a reporting app like Report Pundit fills in what’s missing. Its Inventory Reorder Point report lets you set Lead Days per product, then calculates Safety Stock and the Reorder Point for each variant over any date range you choose. The Inventory Replenishment report adjusts for stock already on its way and breaks needs down by location. Both reports can be scheduled to email or Google Sheets, and they work on every Shopify plan, including Basic.
