How to Combine Weekend Orders into One Shopping List
Aggregate recipe demand, subtract usable stock, and round shortages to real package sizes.
Aggregate recipe demand
Multiply every recipe ingredient by the number of batches required for confirmed orders, then combine identical ingredients only when their units are compatible.
Subtract usable stock
Count stock that is available, in date, and not already reserved. Keep a safety buffer explicit instead of quietly inflating every recipe.
Worked example
Educational example: weekend orders need 4.4 kg flour and usable stock is 0.6 kg. The 3.8 kg shortage requires two 2 kg packs, leaving 0.2 kg after production.
Avoid duplicate names
Standardize ingredient names and units so flour, all-purpose flour, and AP flour do not become three shopping lines for the same item.
Use your own verified receipts and label every example as an estimate.
