SpyGlass vs spreadsheets

Spreadsheets got you here. But there's a point where the tabs multiply, the formulas break, and you're spending a day a week planning — and still stocking out. Here's what changes with SpyGlass.

In short: Spreadsheets can't forecast demand, can't see multiple locations at once, and break silently. SpyGlass adds real per-SKU forecasting, multi-location weeks-on-hand, and freight-aware replenishment — turning a day of manual planning into minutes of review.

Frequently asked questions

Why move off spreadsheets for inventory planning?
Spreadsheets can't forecast demand, can't show coverage across multiple locations, fall out of sync across channels, and break silently — leading to both stockouts and overstock. SpyGlass replaces the manual work with a consistent planning engine.
Is SpyGlass hard to switch to?
No — it's built for teams coming off spreadsheets and stands up in days, not months.
Can I keep exporting to a spreadsheet?
Yes — you can still get the numbers out, but the planning and forecasting happen in SpyGlass so they're consistent and multi-location.
