Change one number. The whole plan moves.
Take Dresses down 2% and the open to buy, the allocation and the replenishment move with it. Every cell keeps the basis it was set from, so the change is a decision you can read back rather than an edit nobody recorded.
Category × month · every cell says where it came from
One number, end to end
The whole season sits on one model. Change a number in one place and it updates everywhere it’s used, straight away.
- Forecast through markdown, all in one model
- Edit anything, and the rest follows
- Open-to-buy everyone plans against
- Always current, so versions never drift apart
One change, all the way to the order.
Move demand on one category and the buy, the allocation and the replenishment move with it, down to the purchase order. Full-price sell-through holds because the buy followed the demand rather than a figure typed in March.
One commitment runs the whole season.
Declare the season once and the buy, the trading week and the review all read that same declaration. Every number keeps the basis it was set from, so a figure checked on one page is the figure on the next.
Declare
A season is declared once: the scope, the window, and five numbers with a basis each. From then on the money reads as one ladder everywhere. Declared, held for the chase, placed, open to commit.
It shows up in the numbers.
“The automation, the forecasting and the supplier tools together make it an absolute no-brainer. We can plan cashmere the way we always wanted to and nobody on the team wants the old way back.”

Tightly · State of Retail Inventory 2026
For retailers & brands
Tuned to the way your category trades.
No two ranges sell the same way. Tightly shapes the forecast, the plan and the buy around how your category actually trades through the season.
New in Tightly.
The Demand agent stages the moves
It flags the categories drifting from plan and queues the rebalance, re-buy and OTB moves, for your review, inside your limits.
Open to buy reads the buy plan
Change the top-down envelope and open-to-buy, allocation and replenishment move with it. Live, not in next month's spreadsheet.
Demand at size-curve level
Every style now forecasts to its own size curve by channel, so the buy commits to the sizes that actually sell.
The forecast is not a chatbot.
Why inventory demand planning needs purpose-built ML, not an LLM, and why a forecast only becomes a plan when bottom-up meets top-down.
