Tightly vs Inventory Planner

Great at reordering. Tightly plans the whole season.

Inventory Planner is a strong demand-forecasting and replenishment tool for DTC brands. Tightly does that too, then reconciles the bottom-up forecast with the top-down merchandise plan, and adds the assortment, size and markdown depth a growing retailer needs.

Why teams switch

Keep what works. Lose what breaks.

01

Keep the forecasting and reordering

Tightly does everything Inventory Planner is known for, a real demand forecast and automated replenishment, and does it at size and channel level.

02

Add the connected plan

The bottom-up forecast is reconciled with the top-down merchandise financial plan and open-to-buy, so buying and the plan never disagree.

03

Grow into merchandising depth

Assortment, size curves, markdown and multi-channel scale, the things a brand needs as it grows past pure e-commerce reordering.

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.
