Ask any head barista where waste hides and milk comes up first. Not because staff are careless — because milk moves constantly, in small amounts, under pressure.
A centimetre too much in every pitcher does not feel like waste until you multiply it across a week of flat whites.
Name the real sources
Before you buy another measuring jug, list how milk actually leaves the building without payment:
- Over-pour and pitcher habit — the silent daily tax
- Remakes — wrong milk, split shots, customer changes
- Expiry — opened bottles that turn before use
- Calibration and purge — necessary, but rarely counted
- Tasting and staff drinks — often informal, rarely logged
Most teams can name these from memory. Few can rank them by cost without data.
Design for the rush, not the office
If waste logging only works at the end of shift, you will get estimates. Estimates smooth over the habits you need to see.
What works on a busy floor:
- Preset reasons — Spoilage, Remake, Over-pour, Expired. No free-text during peak.
- Product-first taps — Whole milk, oat, alternative. Not a full inventory search.
- Batch at quiet moments — Catch up between rushes rather than inventing numbers at midnight.
The test is simple: can a barista log a remake while the next order is heating? If not, the tool is wrong for the floor.
Set a baseline before you optimise
Pick two weeks and log honestly, even if the numbers sting. You are not trying to win those weeks. You are trying to see them.
Operators who do this often find one lever dominates — usually pitcher discipline or remakes after a menu change. Fix that first. Chasing five small habits at once rarely sticks.
Turn insight into ordering
Once you know weekly milk waste in litres — not vibes — ordering changes become obvious. You stop buffering "just in case" on the days you historically over-prepped.
That is where waste logging pays for itself. Not on the compliance slide deck. On the supplier invoice.
Floor mode, in practice
Anteiku's floor view is designed for this exact loop: location selected, product grid visible, one tap to log quantity and reason. No spreadsheet, no end-of-day archaeology.
Start with milk only if you need to. Expand once the habit holds.
