Key takeaways
- Cycle counting counts a rotating subset of stock continuously.
- It keeps inventory accuracy high without halting operations.
- Count frequency is usually driven by item value or velocity.
- Root-causing discrepancies matters more than the count itself.
How does cycle counting work?
Instead of a disruptive annual physical inventory, cycle counting divides stock into groups and counts a portion each day, so every location is verified over a cycle. High-value or fast-moving items are counted more often, using an approach such as ABC prioritization. Discrepancies are reconciled immediately.
The real value is in the discrepancies: coding why a count was off, receiving error, unrecorded move, mis-pick, reveals the systematic causes and lets the operation fix them. InfoSun runs cycle-count programs, increasingly AI-planned, to hold inventory accuracy above 99 percent while the operation keeps running.
Why cycle counting matters
- Sustains high inventory accuracy year-round.
- No operational shutdown for a full physical count.
- Finds and fixes error causes within days, not months.
- Feeds the accuracy that OTIF and planning depend on.
Cycle counting in a 3PL and logistics operation
A multi-client 3PL counts a velocity-prioritized subset of locations every shift and root-causes each discrepancy the same day. Bin-level accuracy holds above 99 percent, client portals promise from live stock, and the quarterly physical inventory that once took the site offline becomes unnecessary.
Frequently asked questions
What is the difference between cycle counting and physical inventory?+
A physical inventory counts everything at once, usually annually, and typically slows or stops the operation. Cycle counting counts a rotating subset continuously during normal operations, so it finds and fixes errors within days rather than discovering them months later. Cycle counting is an ongoing discipline; physical inventory is a periodic snapshot.
How do you decide what to count and how often?+
Most programs prioritize by value or velocity, an ABC approach, counting high-value or fast-moving items more frequently because errors there hurt most. The schedule should ensure every location is verified over a cycle, with the count frequency tuned to how quickly errors would otherwise accumulate.
