WHAT A COUNT IS WORTH

Both sides remember the handover. Neither remembers month seven.

A consignment is not one event. It is a starting count followed by dozens of small changes, and it is the changes that go unrecorded.

The same month, two records

As it happens now

Shop: 13 on hand

Maker: 15 on hand

With a shared count

Shop: 13 on hand

Maker: 13 on hand

same record

A shared count does not decide who is right. It surfaces the disagreement in month seven, while it is still a conversation.

What a shared entry looks like
  1. 22 JunSold · 1 pieceToko RimpangBowl, large. On hand 20 → 19.
  2. 04 JulBroken · 1 pieceToko RimpangVase, tall. Recorded the day it happened.
  3. 04 JulSeenWardah KeramikThe maker knows in July, not in month fourteen.

Every entry names who made it and when. Nothing is written later, and nothing is written by only one side.

At handoverBoth parties agree the number. This part is never the problem.
On each saleThe shop knows. The maker finds out at the next payment, or later.
On a breakageMentioned once, usually apologetically, and rarely written down anywhere permanent.
On a move to storageNobody tells anybody. It is an internal shop decision that changes what the maker will find.
At the endTwo counts that disagree, and no record of which change caused the gap.

A running count that both sides can see removes the argument, because the disagreement surfaces in month seven instead of month fourteen.
