Why statistical inventory sampling finally gives time back: Count less, live more. Statistical inventory sampling saves time, money, and nerves. GESTIN makes it simple and legally compliant.
More time for what really matters: the debate is real, time is scarce
The current discussion about the 40-hour workweek hits a nerve. A young influencer described working 8 hours a day for three weeks and feeling like there’s hardly any day left.
The reactions were harsh, but the core remains. Time is the scarcest resource, and people want more of it for health, friends, family—or for cinnamon rolls, matcha lattes, and BookTok. Posts about it reach millions and keep the debate going.
For companies, this isn’t a side note. Time-wasters at work increase the pressure. One of the biggest year-end time-wasters is the full physical inventory.
Why full inventory slows you down
Full counts lock warehouses, tie up teams, and push projects back. In many warehouses, the Pareto logic applies. A few items account for most of the value. Counting every item just to get the annual value is inefficient. This is where statistical inventory sampling comes in. It allows a mathematically sound partial survey. The law explicitly mentions this in the German Commercial Code (HGB) § 241. The method must follow generally accepted accounting principles and deliver the same informational value as a full count.
Professionally, this is supported by IDW statements and AWV publications. They describe accepted methods, minimum sample sizes, and audit trails. A target of 95 percent confidence and a maximum 1 percent relative error for the total value is named. Valuable edge areas are recommended for full count, with the rest checked by random sampling.
The effect on operations is clear. Fewer count lines. Shorter shut-down times. Less rework. More room for real priorities.
Practice, not theory: how statistical inventory sampling works
The idea is simple. High-value items are fully counted. Low-value items are recorded via random sampling. Mathematical extrapolation confirms the warehouse value with defined confidence. IDW and AWV set out methods and audit rules. Companies document selection, counting, and evaluation. It’s auditable, legally compliant, and saves a lot of time.
The solution for decision-makers: GESTIN by classix
GESTIN is built for this. The software guides you through the seven steps of statistical inventory sampling, creates strata automatically, generates count lists, imports book inventories from the ERP, performs clean extrapolation, and provides final reports for auditors. GESTIN is available in Germany as a cloud service or on premise. The classix software is certified by a renowned audit firm and meets HGB requirements.
The effects are proven. OASE GmbH cut inventory time from 15 to 2 calendar days and reduced count lines from 12,000 to 1,000. That meant about 50 percent of the warehouse value was fully counted and drastically less effort for the rest.
Massivmöbel24 reduced effort from 30 to 8 hours with significantly fewer staff. Downtime dropped noticeably.
What’s left at the end: more time and better mood
Inventory is mandatory. A full count is often optional with no added benefit. With statistical inventory sampling, costs can be cut massively and the whole team relieved. GESTIN makes it simple in practice. Count less. Decide more. And yes, more time for matcha lattes, cinnamon rolls, and your current favorite book.

GESTIN FAQ
Is statistical inventory sampling really permitted?
Yes. HGB § 241 allows sampling with recognized mathematical-statistical methods. The informational value must match that of a full count.
What audit requirements apply?
IDW and AWV define minimum samples, random selection, documentation, and thresholds for error and confidence. GESTIN implements these requirements and delivers audit-ready reports.
How big is the time saving?
Experience ranges from minus 80 percent to minus 95 percent inventory time.
Will it work with my ERP?
Yes. GESTIN imports book inventories from WMS, LVS, or ERP and exports count results back. Interfaces are available.
Cloud or on premise?
Both are possible. Cloud in Germany or installation in your own data center.
How do I start?
Test for free. Import data. Run the first inventory analysis. Count the sample. Create the final report. Then decide on rollout. Run statistical inventory sampling with GESTIN. ROI starts after the first inventory.
