The share of a kitchen's order lines that are items on the order guide it was set up with, at agreed prices. Off-guide lines are priced at list and miss rebates. Low compliance with a guide untouched for a year is a stale guide, not a customer problem.
The kitchen orders what the menu needs. The substitution pairs say what the guide should now contain.
Forty guides with the same pack-size switch are one task, not forty visits.
Order lines for items on the kitchen's order guide, at agreed prices, divided by all its order lines, with guide items not bought in eight weeks listed.
A kitchen's guide has 140 items. It bought 96 in the last eight weeks. The 44 missing include all its fryer oil and most dairy.
The guide set up at onboarding and never compared with what is bought.
