Who this is for: Anyone ordering office, kitchen, cleaning or bathroom supplies, warehouse or safety items, or BOM/BOS material — plus the purchasing team who reviews them.

Purchasing requests used to be emailed to Mark Selph, then moved to the Purchasing Request Form in Google Forms (originally the Office Supplies Request Form). Everything it did is here: the same offices, the same sections, the same items.
Two things are better. The quantity for each item is its own field rather than something you describe in a shared Other box at the bottom of each section, and every request lands in a queue with an approve/reject decision and a record of who decided what.
