Inventory operations, or the plan on top.
Cin7 is a strong connected-inventory operations system. Orders, stock and channels, with the ForesightAI forecasting add-on it acquired. Tightly isn't an operations system. It's the purpose-built planning layer, forecast, buy plan, open-to-buy and assortment, that runs on top of an inventory system like Cin7 and feeds approved POs back.
Keep what works. Lose what breaks.
A planning layer, not another ops system
Keep Cin7 (or your ERP) as the record for stock and orders. Tightly runs the merchandise plan on top and pushes approved POs back. It doesn't ask you to replace what works.
A forecast built for planning
Tightly's forecast is proprietary ML with cold-start for new styles, feeding the buy plan and OTB directly. Not a forecasting module bolted onto an inventory system.
The merchant's plan
The buy plan, open-to-buy, assortment and markdown, the retail planning craft, rather than inventory record-keeping with a forecast attached.
It shows up in the numbers.
“One of the most exciting propositions we've ever brought into the business. There is so much power under the hood that we honestly can't picture running the category without it now.”
Verified outcomes for a wellness devices brand planning long lead times on Tightly.
