For Shopify brands
Inventory planning software for Shopify brands
Shopify tells you what sold. It won't tell you what to reorder, when, or where you're about to run out. SpyGlass turns your Shopify sales into a demand forecast and a weekly replenishment plan.
In short: SpyGlass is inventory planning software built for Shopify brands — it forecasts demand from your Shopify (and Amazon/wholesale) sales, tracks weeks-on-hand across every 3PL and FC, and generates a freight-aware replenishment plan so best-sellers never stock out and cash isn't trapped in overstock.
Why Shopify brands outgrow spreadsheets
A Shopify catalog that started as ten SKUs in one warehouse becomes fifty SKUs across three 3PLs plus Amazon and a wholesale account. That's the moment a spreadsheet stops working: no forecasting, no multi-location view, and a formula error away from a stockout. SpyGlass is the upgrade — without an ERP.
What SpyGlass does for a Shopify brand
- Forecasts demand per SKU from your real Shopify sales velocity
- Adds Amazon and wholesale so you plan every channel together
- Tracks weeks- and days-on-hand across all your 3PLs and FCs
- Generates a freight-optimized replenishment plan in minutes a week
- Alerts on stockouts and overstock before they cost you
Frequently asked questions
What's the best inventory planning software for Shopify brands?
For growth-stage Shopify brands that have outgrown spreadsheets but aren't ready for an ERP, SpyGlass forecasts demand, tracks weeks-on-hand across locations, and plans freight-aware replenishment across DTC, Amazon, and wholesale.
Does SpyGlass connect to Shopify?
Yes — it uses your Shopify sales and inventory to forecast demand and drive the replenishment plan, alongside Amazon and wholesale.
Do I need this if I already have Shopify reports?
Shopify reports are backward-looking. SpyGlass forecasts forward demand, plans multi-location coverage, and tells you what to reorder and when.
