The stores
The transfer and the reorder, worked from what each store holds and sells
Store A holding 180 units against 30 a week and Store B holding 40 against 40 a week is six weeks of cover beside one; moving 86 units levels both at three, and 60 more units cover a three-week lead time, worked on the page before the van is loaded.
The count
Shrink, turns, par and waste from the count you just took
$42,000 opening, $118,000 bought and $160,000 sold at 25% means the count should find $40,000; finding $39,000 is $1,000 of shrink, 0.625% of sales. The par, the cases to order and the waste on a grocery line come off the same kind of sheet.
The entities
Two sets of books netted into one, with the intercompany sales out
$900,000 and $400,000 of revenue is not $1,300,000 when $100,000 of it is one entity selling to the other: the consolidation reads $1,200,000, $280,000 of profit, and $16,000 of it belongs to the 20% the parent does not own. Everything files against the entity and exports.
