What it does

What Sauna does for supply chain planners

01
Build the demand plan
Sauna pulls historical orders and open demand into a Google Sheet, projects requirements by SKU and period, and lays out the netted supply plan against on-hand stock.
02
Flag shortages and excess
It compares projected demand to inventory and inbound POs in the ERP sheet, flags every SKU heading short or overstocked, and ranks them by revenue at risk.
03
Draft purchase recommendations
Sauna drafts reorder quantities by supplier and lead time, lays out the recommended POs, and queues the supplier note in Outlook for your review before anything is sent.
04
Write the planning review
It assembles the weekly S&OP read — fill rate, days of supply, and exceptions — citing the underlying data so the planning meeting starts from facts.

In context

Ask in chat. It does the work.

Sauna shows up where you already work — the web app, Slack, email, iMessage, and Superhuman. It reads what it needs, does the task, and comes back with the draft for your approval.

Good to know

Questions, answered.

Will it place purchase orders by itself?

No. Sauna drafts the reorder quantities and the supplier note. A planner reviews and you approve before any PO or message goes out.

How reliable is the demand projection?

It's built from your order history and open demand, with the method and inputs shown. Sauna flags low-confidence SKUs rather than presenting a guess as a forecast.
