Read the availability calendar

The availability calendar is the grid on Inventory › Calendar. Rows are your products, columns are the days of the month, and each cell says how much of that product is free to promise on that date. It is the fastest way to see the week coming, not the day you are standing in.

Pick a location first

Stock does not combine across locations, so the calendar needs you to pick one. Choose a location and the grid fills in. Without one, you get a plain reminder instead of numbers: a tote at another site is not available here until it is transferred.

Step through months with the ‹ and › buttons, or jump back with This month.

What the numbers mean

Each cell shows the available quantity for that product on that day: what is free to promise, computed from current stock minus holds, bookings, downtime, and prep and turnaround buffers overlapping that date. Clicking a cell opens the pool's product page, where you can check the details behind the number.

The colors tell the story at a glance:

• Free. Plenty left.
• Tight. A quarter or less of the pool is left.
• Zero. Nothing left to promise that day.
• Oversold. Committed beyond stock.

A cell is advisory, not a booking. The calendar answers "what can I promise," and the reservation flow re-checks the real balances the moment someone actually books. Treat a cell as a confident yes for most days and a warning sign for the tight and oversold ones, not as a contract.

Spotting shortages before they happen

The page does the first pass for you. The Constrained days alert lists every date this month with full, tight, or oversold pools, each with chips naming the pool and its remaining number. Oversold pools get the red chip. If the list is empty, the page says so: "Nothing full or oversold this month."

Make it a weekly habit: open the calendar, read the Constrained days list, then scan the grid for Tight cells clustering around a busy weekend. A tight Friday that tightens into a zero by Saturday is a normal busy week. A zero two weeks out with more bookings still arriving is a problem you can still fix: buy stock, adjust buffers, move inventory with a transfer, or schedule downtime on the pool you can't rent anyway.

Oversold is different from zero. Zero means the pool is fully spoken for, which is good business. Oversold means commitments exceed stock, and that one deserves a look today, not next week.

When a cell surprises you

• The calendar says zero but the shelf is full. Holds and bookings on that date are eating the stock, not today's count. Open the pool's page and check what overlaps that window.
• A day shows oversold that you did not expect. Somebody overbooked, usually through the manual override or an up-to-N policy. Check the orders behind it before the rental starts.
• No location picked, no grid. Normal. The page refuses to show a combined view because it would be a promise you cannot keep. Pick a location.
