The continuous inventory For many companies, this is the key to moving the annual inventory count away from the stressful end-of-year period and spreading it evenly throughout the year. Instead of shutting everything down at once to take a count, inventory is recorded and updated on an ongoing basis. In this article, you’ll learn exactly what perpetual inventory is and what legal requirements apply according to § 241 HGB what the process looks like in practice and what advantages and disadvantages you should be aware of—including a specific example and how to implement the process properly using digital tools.
In the continuous inventory (also ongoing inventory (as mentioned) the inventory count, in terms of both quantity and value, is not conducted on a single reporting date, but rather spread out continuously over the entire fiscal year. This is made possible by maintaining an up-to-date inventory record in which every receipt and every issuance is documented.
On the actual balance sheet date, no physical count is conducted. Instead, the inventory figures are taken from the records maintained on an ongoing basis Inventory Update taken over—that's what you call a Book Inventory. The requirement is that each asset must have been physically counted, measured, or weighed at least once during the year and reconciled with the book inventory.
Perpetual inventory is thus one of several permissible Inventory Procedures – in addition to the traditional point-in-time inventory, the staggered inventory, and the spot-check inventory.
Continuous inventory is expressly permitted in Germany. The legal basis for this is § 241(2) of the German Commercial Code (HGB), which permits simplified inventory procedures provided that the reliability of the annual financial statements is maintained. In addition, the following apply: Principles of Proper Accounting (GoB) as well as the Income Tax Guidelines (R 5.3 EStR) for tax recognition.
In order for the tax office to recognize the perpetual inventory system, the following must be met: all The following requirements must be met:
Important: For assets subject to uncontrollable shrinkage—particularly valuable goods or inventory at high risk of theft—continuous inventory is generally not Permissible. In this case, the law requires that the entry be made closer to the balance sheet date.
In practice, continuous inventory is carried out in recurring steps:
A small business with 4,000 items (tools, supplies, machinery) wants to avoid the stress of the end of the year. Instead of counting everything all at once in December, it divides its inventory into twelve zones Every month, a zone is physically inventoried and compared with the digital target inventory.
As of the balance sheet date (Dec. 31), the company must nothing matters anymore: The inventory is based on ongoing updates. Each item was checked at least once during the year—the requirements have been met.
| Procedure | Date of admission | Typical Application |
|---|---|---|
| Point-in-Time Inventory | In full as of the balance sheet date | Smaller collections, traditional |
| Postponed Inventory Count | Within 3 months before or 2 months after the reference date | Adjustment of the Cut-off Date |
| Continuous Inventory | Ongoing throughout the year | Warehouse with effective inventory management |
| Inventory by Sampling | Extrapolation from a representative sample | Large, homogeneous populations |
Perpetual inventory is often confused with the Inventory by Sampling Combined: Ongoing data collection ensures up-to-date inventory figures, and the use of a sample further reduces the effort required for counting.
The key to success is accurate, complete inventory updates—and this is precisely where the process often falls short in practice due to Excel spreadsheets and disorganized paperwork. A Inventory Management Software Automates the update: Every addition and removal is processed via Barcode or QR Code Scan Booked directly, the target inventory is always up to date, and counts can be performed on the go via an app.

Yes. Continuous inventory is, according to § 241(2) of the German Commercial Code (HGB) is expressly permitted as a method to simplify inventory taking, provided that the reliability of the annual financial statements is maintained and proper inventory records are kept.
Each asset must at least once per fiscal year be physically counted (counted, measured, or weighed) and reconciled with the book inventory.
In a periodic inventory, the entire inventory is counted on the balance sheet date. In a perpetual inventory system, physical counts are spread out over the entire year, and on the balance sheet date, a book inventory based on the ongoing inventory updates is sufficient.
For particularly valuable inventory items, as well as for goods subject to uncontrollable shrinkage or a high risk of theft, continuous inventory counting is generally not permitted. These items must be counted closer to the balance sheet date.
You need comprehensive inventory accounting with real-time inventory updates, at least one physical inventory count per item per year, documented counts, and a documented reconciliation of target and actual inventory levels.
