Dates that move on their own

This is the part of the calendar most studios underuse.

The receiving buffer

Settings → Calendar → Receiving buffer.

This is the time between goods leaving the vendor and goods being ready to install: transit, receiving, inspection, damage claims, delivery to site.

Order-by date = install date − vendor lead time − receiving buffer.

Set it once, and every red order-by chip on the calendar is computed from it. Change it, and they all move.

Per-project buffers

Settings → Calendar → Projects with their own buffer.

A distant site, a building with a booked service elevator, a warehouse that holds goods before release — those projects receive differently. Give them their own number. Leave a project blank and it follows the studio default.

Tracking writes the dates

If you have shipment tracking on a product, carrier updates write the procurement dates for you — so the delivery chip moves on the calendar without anyone touching it.
