What this is
What is an inventory adjustment authorisation?
What is an inventory adjustment authorisation?
It is the approval record for a deliberate change to a system stock quantity, holding the before and after figures, the value, the reason, the evidence behind that reason, and the identity of the person who approved it. The posting in the warehouse system is the transaction; this record is the authority for it, and it is the only place the reasoning survives.
Why does an adjustment need authorising at all?
Because a stock figure is a financial balance as well as an operational one, and the ability to change it without challenge is the ability to make a loss disappear. Adjustment authority is a standard key control in internal control over financial reporting, and it is the control that shrinkage, mispicking and theft all have to pass through before they become invisible.
What is segregation of duties in this context?
That the person who counts the stock, the person who requests the correction and the person who approves it are not the same person and do not report to each other for the outcome. Approval one level up inside the same team satisfies the letter of most procedures and none of the intent, because the supervisor's own accuracy figures depend on the adjustment going through quietly.
Scope
When is an inventory adjustment authorisation required?
This record authorises a change to a figure. It does not establish what happened, and using it as though it does is what turns an inventory control into an inventory laundry. Everything upstream of the authority belongs to a neighbouring record.
Use this template when
- A count has been reconciled and the system figure must now be corrected to the physical quantity
- Stock has been written off as damaged, expired or destroyed and the system still shows it as available
- A shortage or overage against a receipt or despatch has been confirmed and the investigation is closed
- Consignment or bonded stock has been reconciled with the owner and the difference must be authorised rather than absorbed
- A location correction crosses a value or lot-control threshold and needs approval rather than a warehouse move
Do not use it for
- Establishing why the figures disagree, which is the Stock Count Variance Investigation (LOG-014) and must be complete before any authority is sought
- Counting the stock, which is the Cycle Count Record (LOG-013); an authorisation is not a count sheet and should never be the first record of a quantity
- Recording the damage, its cause and its disposal route, which is the Damaged Stock Record (LOG-017)
- Confirming that stock is where the system says it is, which is the Stock Location Audit (LOG-016) and usually needs no quantity change at all
- Investigating a picking or despatch shortfall against a customer order, which is the Shortage Investigation Record (LOG-028)
Compliance mapping
Which ISO 9001 cl.8.5.4 requirements does this satisfy?
Stock adjustment sits across two regulatory families that rarely appear on the same form. The quality standards treat it as control of an output and of the documented information about that output; the financial and customs regimes treat it as a key control over a reported balance. A record that satisfies one and not the other fails an audit somewhere.

| ISO 9001 cl.8.5.2 | Identification of outputs and control of unique identification where traceability is required, with documented information retained | Header |

What it does not cover
- The variance investigation, which establishes why the figures disagree and must be complete before authority is sought, not summarised in a reason code afterwards.
- The financial posting, which lives in the ledger under its own journal authority and period controls; this record is the operational authority for it, not the entry itself.
- Physical security and loss prevention, which covers access control, CCTV review and the loss investigation itself when the cause is theft rather than error.
- Cycle count programme design, which decides what is counted, how often and to what tolerance, and which determines how many adjustments you should expect in the first place.
- Any disciplinary or criminal process, which has its own evidential standard and must not be prejudiced by an adjustment record written to close a stock figure.
Global
Inventory Adjustment Authorisation requirements by country
Stock is a physical fact and a reported balance at the same time, so adjustment authority is regulated twice: once as an internal control over financial reporting, and again, in bonded, pharmaceutical and food supply chains, as a traceability and accountability duty.
Sarbanes-Oxley Act s.404; PCAOB AS 2201; 19 CFR 19.12 for bonded warehouses
Inventory adjustment authority is a documented key control for registrants, and a licence condition for bonded stock.
External auditors test this control by sampling adjustments and checking approver independence, so a single self-approved adjustment in the sample becomes a control deficiency rather than a warehouse error.
Companies Act 2006 s.386; HMRC Excise Notice 196 for warehoused goods
Adequate accounting records required, including statements of stock held at the year end and the records from which they were prepared.
For excise or customs-warehoused goods the deficiency must be declared and duty may become payable, so an adjustment posted quietly to tidy a figure can create a tax liability nobody has told HMRC about.
EU GDP Guidelines 2013/C 343/01, chapter 5; EU GMP Part I chapter 5
Periodic stock reconciliations required, with discrepancies investigated and recorded before the record is corrected.
An inspector reading a wholesale dealer's adjustment log expects to find an investigation reference against every discrepancy, and unexplained adjustments of medicinal product are treated as a potential falsified-medicines route.
Customs Bonded Warehouses Regulations; Canada Business Corporations Act s.20
Licensees must account for goods received and removed and keep records available for inspection.
Accountability sits with the licensee regardless of who made the error, so adjustment authority is also the point at which a customs exposure is accepted.
Corporations Act 2001 s.286; warehouse licence conditions under the Customs Act 1901
Financial records must be kept to explain transactions and enable true and fair reporting; licensed premises carry stock accounting duties.
The record has to explain the transaction, which means a reason code alone will not satisfy an auditor asking why the balance moved.
ISO 9001 cl.8.5.4 and cl.5.3; IAS 2
Preservation and traceability of outputs, defined authorities, and measurement of inventory with write-downs recognised when they arise.
Certification and financial audit converge on the same evidence: the authority limit, the person who applied it, and the basis on which they did.
How to complete it
How to complete an inventory adjustment authorisation, step by step
Filling this in takes two minutes and the figures come from the system. Whether the record is defensible is decided by four judgements made before anybody opens it.
The order in which the record is completed determines its honesty. Once the adjusted quantity is entered, the reason becomes whatever code makes the posting go through. Establish what happened to the units first, from the investigation, and let the reason drive whether an adjustment is even appropriate: unrecorded issues and misdespatches are corrected by posting the missing transaction, not by adjusting the balance.
The approver must have no interest in the count's accuracy figures. A shift manager approving their own team's corrections meets almost every written procedure and defeats the control entirely, because the adjustment removes evidence of a problem the approver is measured on. Route approval to inventory control, quality or finance, and make the requesting area the one place it cannot go.
Not A Repeat Of Last Period is the field most likely to be answered without checking and most likely to matter. A material and location that adjusts every count cycle is telling you about a process defect, usually an unrecorded consumption route, a unit-of-measure conversion error or a location that two systems disagree about. Each adjustment will be small, evidenced and properly approved, and the pattern is the finding.
Recorded Before The Period Closed exists because a late adjustment restates a figure that has already been reported. Set an operational cut-off ahead of the financial one, and treat anything found afterwards as an item for the next period with a note, rather than back-dating it to the one that is closing. Back-dated adjustments are the pattern external auditors look for first.
What auditors find
Most common inventory adjustment authorisation findings
Adjustment findings divide cleanly. Half concern who approved it, and are found by sampling. Half concern what the reason actually was, and are found only by sorting the whole population by material and location.
| Finding | Clause | What fixes it |
|---|---|---|
| Adjustment posted before the variance investigation was complete, with the investigation reference added afterwards. | ISO 9001 cl.10.2 | Gate the posting on a closed investigation reference; without one the adjustment writes off the cause. |
| Requester and approver are the same person, or the approver reports to the requester. | ISO 9001 cl.5.3 | Encode the approval matrix in the routing so self-approval is impossible, not merely prohibited. |
| One loss split into several postings, each below the approval threshold. | SOX s.404 | Aggregate adjustments by material, location and week before applying the value threshold. |
| Counting error used as the reason with no physical count evidence held for the corrected figure. | ISO 9001 cl.10.2 | Require count evidence before that reason is accepted, and offer loss of unknown cause as a valid code. |
| Same material and location adjusted in every count cycle, each adjustment individually approved. | ISO 9001 cl.9.1.1 | Report adjustments by material and location rather than by value, and raise a CAPA at the third occurrence. |
| Adjustment dated after the period closed, restating a reported stock and financial position. | IAS 2 | Set an operational cut-off ahead of the ledger close and carry late items forward with a note. |
| Batch or lot number omitted on an adjustment to lot-controlled stock. | ISO 9001 cl.8.5.2 | Make batch mandatory where the material is lot-controlled; traceability breaks at the adjustment, not at receipt. |
| Finance not informed of adjustments above the materiality threshold until month-end reporting. | SOX s.404 | Route material adjustments to finance at the point of approval, with the value and the reason. |
| Approved record subsequently edited, with no history of what changed or who changed it. | ISO 9001 cl.7.5.3.2 | Lock the record at approval and require a superseding adjustment rather than an amendment. |
| Printed packaging or labelling reconciled and corrected without the discrepancy being investigated. | 21 CFR 211.125(c) | Investigate and document every labelling discrepancy before the reconciliation is signed off. |
Case in point
Case in point: seventy thousand pounds of film, four hundred pounds at a time
A contract packing site ran weekly cycle counts on packaging materials. The approval matrix allowed a shift supervisor to authorise adjustments up to five hundred pounds in value, with anything above that going to the inventory controller and anything above five thousand going to finance. The matrix had been signed off by internal audit two years earlier and was, on its own terms, a reasonable control.
Over fourteen months, adjustments to reel film at three pick faces averaged four hundred and twenty pounds and appeared almost every week, always coded as counting error, always approved by the supervisor whose team had performed the count. Every single one was within authority, correctly signed, correctly dated and supported by a recount. The cumulative write-off was a little over seventy thousand pounds. Nobody ever saw the total, because the adjustment report was sorted by value and every line was small.
It surfaced when a new inventory controller sorted the same twelve months by material and location instead. The cause turned out to be mundane rather than criminal: film was being drawn for machine set-up and waste without any issue transaction, so real consumption left the system through the adjustment route every week. The control that failed was not the threshold. It was that the threshold was the only control, and a threshold applied per posting cannot see a pattern.

From a document you fill in to a programme that runs itself
The form is trivial. What fails is everything around it: the investigation that was never linked, the approver who should not have been in the chain, and the pattern that nobody could see because the report was sorted by value.
Holds the adjustment population against the location and material registers, enforces the approval matrix in the routing, and reports adjustments by material and location rather than by size.

Watches for the patterns a single record cannot show: repeat adjustments at one location, one reason code carrying most of the value, and one approver carrying most of the postings.
Keeps the delegated authority schedule and the segregation-of-duties rules as controlled documents, and evidences to auditors that the limits applied were the limits in force.
Takes the recurring adjustment into a nonconformity and corrective action, so an unrecorded consumption route is fixed rather than corrected weekly.

Glossary
Inventory Adjustment Authorisation definitions and key terms
- Stock adjustment
- A deliberate change to a system quantity to bring it into line with a physical fact, distinct from a transaction that records stock actually moving.
- Write-on and write-off
- An adjustment increasing or decreasing the recorded quantity. Write-ons are treated as benign and rarely investigated, which is why they are the more useful of the two to trend.
- Reason code
- The classification attached to an adjustment. Its accuracy determines whether the underlying cause can ever be trended, and it is the field most often chosen for convenience.
- Segregation of duties
- The separation of counting, requesting and approving so that no one person can both create and conceal a discrepancy.
- Book-to-physical variance
- The difference between the system quantity and the counted quantity before any adjustment, which is the figure an investigation works from.
- Shrinkage
- Net unexplained inventory loss over a period, of which authorised adjustments coded as error are the most common hiding place.
- Delegated authority limit
- The value up to which a named role may approve an adjustment, set out in a schedule and tested by auditors against actual postings.
- Net realisable value
- Estimated selling price less costs to complete and sell, the ceiling at which inventory may be carried and the basis on which a write-down is measured.
FAQ
Frequently asked questions about inventory adjustment authorisation
Can a supervisor approve an adjustment to a count their own team performed?+
No, and this is the most common breach in practice. The supervisor's accuracy metrics improve when the variance disappears, so they are approving the removal of evidence about their own performance. Seniority is not independence. Route approval to inventory control or finance, and treat any adjustment approved inside the counting area as a control exception whatever its value.
Does every adjustment need an investigation first?+
Every one outside the count tolerance, every repeat on the same material and location, and every one on lot-controlled or bonded stock, regardless of value. Small discrepancies resolved by an immediate recount need no investigation because nothing was actually missing. The distinction is whether physical count evidence supports the new figure, not whether the number is large.
Is a reason code enough of a reason?+
No. A code is a bucket for reporting; the reason is the account of what happened to the units, and it belongs in the record alongside the reference to the investigation that established it. Codes with no narrative produce reason-code reports where sixty per cent of value sits under counting error, which is the same as having no reason data at all.
What value should the approval threshold sit at?+
Wherever your materiality sits, but the threshold should not be the only trigger. Escalate on value, on repeat occurrence at the same material and location, and on lot or bond control, whichever fires first. A five-hundred-pound limit with no repeat rule is defeated by anyone patient enough to split a loss across four weeks.
Should adjustments be posted immediately or batched at period end?+
Immediately. Batching means the system figure is knowingly wrong for days, which corrupts availability, replenishment and allocation decisions in the meantime, and it concentrates approvals into a rush where scrutiny is weakest. Post them as they are authorised and set the operational cut-off before the ledger close, not with it.
Who owns the adjustment: the warehouse or finance?+
The warehouse owns the cause and the evidence; finance owns the balance and the materiality judgement. In practice the record needs both signatures for anything material, which is why the form carries an inventory controller and a finance signature. Where one function owns it alone, the failure is predictable: warehouse-only ownership loses the value discipline, finance-only ownership loses the reason.
