Coffee net sales$10,500
Bean purchases$1,860
As a share of all cafe net sales8.6%

Beans account for 17.7% of coffee sales in this example. Include milk and packaging to understand the broader cost. A large bill on its own does not mean coffee is performing poorly.

What is included

Illustrative week, 18 to 24 September. Net sales exclude GST. Costs exclude recoverable GST. Coffee sales of $10,500 are a sample category total, not inferred from a venue’s overall sales.

Bean purchases$1,860

This view excludes milk, cups, lids, other ingredients, labour and overheads.

This is a purchases-based estimate, not a confirmed gross margin. Stock movements can make purchases differ from what was used. With complete stock usage and reviewed allocations, Iris can calculate category gross profit before labour and overheads.

Ingredients and wages belong in different places.

A P&L section can contain both. Review the underlying accounts so Iris follows product costs and Luna follows wages and super.

A possibility from Iris · Scenario

What would one percentage point mean?

At the same $21,580 net sales, a one-point reduction in product cost represents $215.80 per week. Investigate waste, portions and supplier prices before treating it as a saving.

A drafted supplier price check

Supplier price checkDrafted Wed 23 Sept

Hi Brownes team, quick one. Our 2L full cream moved from $3.10 to $3.35 on the 18 September invoice, about 8%. Is that the new standing price or a one-off? Thanks, Sample cafe.
