Cycle Counting SOP Template

1.Purpose

To verify physical inventory against system records on a rolling schedule, catching and correcting errors early without the cost and disruption of a full physical inventory.

2.Scope

Applies to scheduled and ad hoc cycle counts of storage and pick locations across the warehouse. Full annual physical inventory and daily transaction recording are covered elsewhere.

Definitions

Cycle count

A scheduled count of a subset of inventory locations, repeated on a rotation so all locations are eventually counted.

ABC classification

A method of grouping SKUs by value or movement (A high, B medium, C low) to set different count frequencies.

Blind count

A count performed without the counter seeing the system quantity, to reduce bias toward confirming the expected number.

Tolerance

The acceptable difference between counted and system quantity before a variance requires investigation.

3.Responsibilities

Count Clerk

Performs blind counts of assigned locations and records results on the count sheet or scanner.

Inventory Control Manager

Schedules count cycles, reviews variances, and approves adjustments.

Warehouse Supervisor

Frees up staff time for counts and restricts location activity during a count.

Recount Auditor

Performs an independent second count on locations with a variance outside tolerance.

5.Procedure

1. 5.1

   Classify SKUs by count frequency

   Inventory Control Manager

   Group SKUs into A, B and C classes by value or pick frequency, and set a count frequency for each class, such as monthly for A items and quarterly for C items.

2. 5.2

   Generate the day's count list

   Inventory Control Manager

   Pull the day's assigned locations from the rotation schedule, mixing in any locations flagged by recent pick errors or negative on-hand alerts.

3. 5.3

   Freeze the location

   Warehouse Supervisor

   Flag each location being counted as frozen in the WMS or with physical signage so pickers and putaway staff avoid it until the count is complete.

   Warning: Counting a location while stock is still being picked or put away will produce an inaccurate variance.

4. 5.4

   Assign counters to locations

   Inventory Control Manager

   Assign each frozen location to a count clerk, avoiding assigning a clerk to a location they stock or pick regularly where practical.

5. 5.5

   Perform the blind count

   Count Clerk

   Scan the location barcode, then count and enter the physical quantity of each SKU present without viewing the system quantity first.

   Checkpoint: The count is entered before the system quantity is displayed, preserving the blind count.

6. 5.6

   Check for misplaced or unscanned stock

   Count Clerk

   Look behind, above and inside cases in the location for stock that may not carry a visible barcode, and note any item found in the wrong location.

7. 5.7

   Submit the count

   Count Clerk

   Submit the completed count for the location in the WMS or hand in the count sheet, and release the location freeze once the count is submitted.

8. 5.8

   Compare against tolerance

   Inventory Control Manager

   Compare each submitted count to the system quantity and flag any SKU where the variance exceeds the defined tolerance for its ABC class.

9. 5.9

   Recount out-of-tolerance locations

   Recount Auditor

   Assign a different counter to independently recount any location with an out-of-tolerance variance before it is accepted as final.

   Checkpoint: A second, independent count confirms the variance before any adjustment is approved.

10. 5.10

    Investigate the root cause

    Inventory Control Manager

    For confirmed variances, review recent transactions, nearby locations and open orders to identify a likely cause such as a mis-pick, mislabeled location or data entry error.

11. 5.11

    Approve and post the adjustment

    Inventory Control Manager

    Approve the adjustment with a reason code and post it to the WMS, referencing the original count and recount results.

12. 5.12

    Report accuracy results

    Inventory Control Manager

    Log the count, variance and adjustment outcome in the cycle count report and summarize accuracy rate by ABC class at the end of each cycle.

6.Quality checks

• →Every count is performed blind, without the counter seeing the system quantity first.
• →All out-of-tolerance variances are recounted by a different clerk before adjustment.
• →A class locations are counted at least as often as the schedule requires.
• →Adjustments always reference a documented root cause.

7.Records

• →Cycle count schedule and completion log
• →Count sheets or scanner exports
• →Variance investigation log
• →Cycle count accuracy report by ABC class

8.KPIs

• →Location count accuracy rate by ABC class
• →Percentage of scheduled counts completed on time
• →Average variance value per count cycle
• →Days to resolve an out-of-tolerance variance

9.Common mistakes

• →Letting pickers work a location while it is being counted.
• →Skipping the recount step on a large variance to save time.
• →Counting only what is visible without checking behind or above stock.
• →Falling behind on C-class counts because A-class locations get all the attention.
