Stock, explained by its movements

Stock is a balance, so it rolls forward. May opened at 10,240 units, took in 2,180 net of reversals, issued 1,420 to production and deliveries, and closed at 11,000, the number the overview and the aging both carry.

RuleRoll stock forward monthly from movement lines: opening units, plus receipts, minus issues, equals closing, reconciled to the stock overview before anyone reads either.

Neverquote on-hand without its movements. A stock number that cannot show what arrived and what left is the number warehouse counts disagree with.

Stock is a balance, so it rolls forward. The movements are the explanation the count sheet will ask for.

◆ May, rolled forwardmovements folded to one line.

Units, plant 2100, May 2026	Units
Opening on hand, 1 May	10,240
Receipts, net of reversals and returns	2,180
Issues to production and deliveries	-1,420
On hand, 31 May	11,000

The receipts line is the movement partition’s 101 units net of 102 and 122; the issues line is 261 plus 601. The closing is the stock overview’s total and the aging page’s on-hand, one number in three places. Sample values are illustrative, never client data.

◆ Why the fold matterscounts argue with balances, not flows.

When a cycle count disagrees with the system, the argument is only winnable with movements on the table: what arrived, what left, what transferred, in which week. A roll-forward from landed MATDOC lines turns the count meeting from assertion into subtraction.

◆ The owned answerany month, the same fold.

Landed movement lines make the roll-forward a grouping by month, so every prior month keeps its own bridge, and the as-of reconstruction problem disappears: the past is stored, not rebuilt through reversals.

Use case

Problem

On-hand moves month to month with no bridge, cycle counts turn into arguments, and past stock levels get rebuilt through every reversal since.

What we build

A monthly units roll-forward folded from landed movement lines, closing reconciled to the stock overview and the aging nightly.

What you get

A stock balance with its story attached: every movement named, count disputes settled by subtraction, and history that stays what it was.

Can you bridge last month’s stock to this month’s?

We build the roll-forward that folds the movements for you.
