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, MFP, 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 MFP and OTB directly — not a forecasting module bolted onto an inventory system.
The merchant's plan
MFP, 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.
“We scaled into a facility four times the size and expanded into entirely new categories — managing it all with the same lean team. Tightly didn't just automate our stock, it gave us the confidence to grow.”
Beauty & wellnessFace the Future hit these numbers after moving into a facility 4× the size, with the same lean team.
Across beauty, the leaders sell 71% at full price against 57% — a 14-point gap, won by acting on demand signals faster.
