Year-end, sample or perpetual count: which method fits?

The head office in Germany asks for a "stock count at year end", and the warehouse manager in Tashkent wonders: do we count everything on one day, draw a sample, or spread the counting over the whole year? The answer depends less on preference than on your warehouse. Range, turnover, bin system and the expectations of head office and auditor all play a part. This article shows how the three common methods differ and how to justify your choice.

The three methods in brief

• In a year-end count, the entire stock is counted on one fixed day or within a short window and compared with the book stock.
• In a sample-based count, a selection is drawn under a fixed scheme and counted, and the result is projected onto the total stock.
• In a perpetual count, zones and item groups are counted according to a plan spread over the financial year and documented as you go.

All three have the same aim: the stock in the books should match the stock on the shelves, and the way to that result should be traceable.

Five questions that decide the choice

1. How many items (SKU) and how many bin locations does the warehouse have?
2. How fast does the stock turn over? A warehouse with daily dispatch cannot stand still for several days.
3. How uniform is the range? Many similar cartons of similar value suit a sample better than a few high-value single pieces.
4. How reliable is your day-to-day stock record? A perpetual count needs unambiguous bin locations and timely postings in 1C or the ERP system.
5. What does head office require, and what does your auditor accept?

Three warehouses, three answers (fictional examples)

Spare-parts warehouse: 2,400 items, operating in the day shift only, dispatch quiet at weekends. Assume one count team manages 40 positions an hour, so 320 in an eight-hour shift. With a second count there are 2,400 × 2 = 4,800 count positions. Eight teams complete 8 × 320 = 2,560 positions per shift, so the whole stock is recorded in just under two shifts (4,800 ÷ 2,560 ≈ 1.9). A year-end count over a weekend is realistic here.

Wholesale warehouse: 18,000 items, mostly uniform carton goods. A complete count with a second count would mean 36,000 positions, which for eight teams is more than 14 shifts (36,000 ÷ 2,560 ≈ 14.1). It is worth examining a sample here, provided head office and the auditor accept the method for your accounts.

Distribution warehouse with daily dispatch: 24 zones, no standstill possible. A perpetual count covers two zones a week. After twelve weeks every zone has been counted once, and about four times a year. It is usually expected that every item is physically counted at least once during the financial year. What exactly this requires for your accounts is something to clear with your auditor.

Mixed forms and changing methods

The methods do not exclude each other. Some companies count high-value or shrinkage-prone items completely every year and check uniform bulk goods by sample. Others move from a year-end count to a perpetual count after a few years, once bin locations and posting discipline are stable. What matters is that every mixed form is laid down in writing: which area is counted by which method, and why.

What to clarify beforehand

• Which methods your group guideline provides for or rules out.
• Which methods your auditor accepts for the annual accounts, and with what documentation.
• Whether local accounting sets additional requirements for timing and form.

The requirements of commercial law, tax law and auditing standards are complex and change over time. Always discuss the choice with your auditor and tax adviser.

In short

A small, manageable warehouse is usually counted in full at year end, a large and uniform range allows a sample, and a warehouse with high turnover often does better with a perpetual count. AuditMaster carries out all three methods and, after the warehouse walkthrough, makes you a concrete proposal for method and schedule.
