The AI agent for merchandise planners
Sauna reads sales and inventory from Shopify and your planning sheets, builds the open-to-buy, projects weeks-of-supply by SKU, and drafts the reforecast when a style runs hot or cold.
What it does
What Sauna does for merchandise planners
- 01
Run the open-to-buy
Sauna pulls on-hand, on-order, and sales rate from Shopify and Google Sheets and computes the open-to-buy by category, writing the working OTB sheet for your review.
- 02
Project weeks of supply
It calculates weeks-of-supply per SKU from current sell-through and flags the styles that will stock out or overstock before the season ends.
- 03
Reforecast the season
When a style breaks from plan, Sauna drafts the revised forecast in Airtable with the new sales curve and the markdown or reorder it implies.
- 04
Prep the WSSI
It assembles the weekly sales, stock, and intake report in Smartsheet and posts the variance-to-plan summary to your Slack channel.

Good to know
Questions, answered.
Will it place reorders automatically?
No. Sauna projects supply and recommends the reorder or markdown, but the purchase order stays your decision and is placed only after you approve.
Can it handle my existing OTB template?
Yes. It works inside your connected planning sheet and follows your category structure and formulas rather than imposing a new format.
Is my data safe?
Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
