Stock-count software should preserve the expected stock basis, capture observed quantities and route differences for authorised review. Counting is not the same as posting an adjustment. Define movement controls, units and recount rules so a variance can be explained rather than simply overwritten.

Let’s plan your stock count process.

Bring your workflow, constraints and open questions. We’ll help you define the requirements and work through a practical next step.

01

Agree the count boundary

Identify locations, items, batches and the point in time being counted. Decide whether movements pause, remain allowed under a controlled method or require reconciliation afterwards. A count compared with a changing stock total can produce differences that are timing artifacts.

Specify blind counting where appropriate: counters enter observations without seeing the expected quantity. Have the business owner decide whether that fits the process and who can view the comparison.

02

Use a count and variance worksheet

Distinguish not counted from counted as zero. An empty field should not erase stock or imply a verified absence.

03

Handle ordinary warehouse complications

For a hypothetical warehouse, stock may be physically present but reserved, damaged or in a staging area. Specify whether the count records physical quantity, available quantity or separate states. Mixing those meanings produces misleading variance reports.

Support the agreed unit conversions and identifiers. A sealed carton and loose units need a traceable calculation, not a free-text note that only the original counter understands.

04

Test posting and recovery

Include repeated submission, an expired counter session and a stock movement after the snapshot. Revalidate adjustment authority and prevent duplicate posting.

Keep a useful correction route after a mistake. Record the original observation and later decision according to the approved history policy rather than editing the count until it agrees with the ledger.

05

Stock-count questions

Should every variance automatically change inventory?

No. Use the organisation's review and adjustment rules, with appropriate authority for consequential changes.

Is a zero variance proof the inventory system is correct?

It supports the defined population and count conditions. It does not establish every item, location or historical movement was verified.

Pair counts with inventory scope selection, and discuss movement controls with Drema's ERP team.
