What Is an Inventory Adjustment?

An inventory adjustment is a manual ledger entry that corrects a product's on-hand quantity to match a physical count, posted as a signed delta with no linked order. Positive adds stock the system was missing, negative removes stock that is not really there. It is the auditable way to reconcile the record with the shelf.

This entry defines the inventory adjustment and shows how it reads inside EDGEBIC by User Solutions. For the wider index of terms, see the manufacturing glossary; for the record it belongs to, see what is an inventory ledger; and for the planned movement it contrasts with, see inventory issue transaction.

How it works

An inventory ledger records stock movements as signed entries: receipts add, issues remove. Most entries are pegged to something, a build order that completed, or a demand that pulled from stock. An adjustment is different. It is a correction, not a planned movement, so it links to no manufacturing order and no purchase order. It just says the truth of the shelf differs from the record, and here is the delta that fixes it.

The delta is signed. Find 5 more than the system thought, and you post plus 5. Find 2 fewer, perhaps from damage or a miscount, and you post minus 2. The entry is dated, stamped with the transaction type Adjustment, and carries whatever comment you write. The on-hand balance is recomputed in the same transaction, so the correction is instant and consistent everywhere.

Because the ledger is append-only, the adjustment is permanent. It is never a quiet edit to a stored quantity. That is the whole point: an auditor, a planner, or a future you can read the ledger in date order and see every correction, when it happened, and why.

A concrete example

A product's ledger reads 120 on hand after an opening balance and one issue. A cycle count on Tuesday finds 125 physical units on the shelf. Rather than wonder where the extra 5 came from and edit a field, you post an adjustment of plus 5 with the comment cycle count.

The on-hand is now 125, and the reason is right there in the ledger. The adjustment did not pretend to be a receipt from a build or an issue against an order, because it was neither. It was a count correction, and the record says so. The next projection and the next scheduling run both read 125 as the authoritative figure.

How EDGEBIC uses it

In EDGEBIC, an inventory adjustment is entered in the inventory area's adjustments view: you enter the delta quantity, positive to add or negative to remove, and a ledger entry of type Adjustment is appended. The adjustment does not link to any order, and the on-hand cache is updated atomically in the same transaction, so every screen shows the corrected balance without a refresh.

Adjustments sit alongside the other recognized transaction types, receipts, issues, reversals, and the opening balance, in one append-only ledger. Because the authoritative on-hand is the sum of all entries, a diagnostic check watches for cache drift, flagging any product whose cached quantity has fallen out of step with the ledger sum, so a skipped recompute never hides.
