Perpetual Inventory SystemInventory doesn’t wait for period end.
The Perpetual Inventory System applies the perpetual inventory method: every stock movement recalculates quantity, unit cost and stock value, and the cost of goods sold reaches accounting at the moment of sale. Stock information stays current with the daily flow of the business.

Period-end inventory versus perpetual inventory
With the periodic method, stock value and the cost of goods sold are only known after the period-end count. In the Perpetual Inventory System, which applies the perpetual method, they are updated with every movement.
| Periodic inventory | Perpetual Inventory System | |
|---|---|---|
| Stock quantity | Confirmed by the period-end count | Current with every movement |
| Stock value | Calculated at period end | Visible item by item at any time |
| Cost of goods sold | Found in total at period end | Calculated per sale, at the moment of sale |
| Gross profit | Cannot be measured before closing | Tracked at the moment of sale |
| Count differences | Investigated after the fact | Seen immediately against the system balance |
| Period-end workload | Heavy | Lower; closing is faster |

One movement, four outcomes
Perpetual inventory is a method; the Perpetual Inventory System applies it and treats stock, cost and accounting as parts of the same movement, not as separate tasks.
- 01
The movement is recorded
A stock movement such as a purchase, sale, return, transfer between warehouses or count difference is posted item by item.
- 02
Values are recalculated
The item’s stock quantity, unit cost and stock value are updated with the movement.
- 03
Accounting is updated
The movement’s journal entry is created; for sales, the cost of goods sold is posted at the moment of sale.
- 04
Reports stay current
The inventory list, stock value and profitability can be tracked without waiting for period end.
Benefits for your business

Because the cost of each sale is calculated, gross profit is tracked per sale.
Item-level traceability
Each item’s receipts, issues and balance are kept chronologically in the system.
Consistent stock and accounting
The stock balance and accounting entries are fed by the same movement.
Faster period close
The need for bulk cost calculations at period end is reduced.

Frequently asked questions
What is perpetual inventory?
Perpetual inventory is an inventory method in which stock movements are recorded as they happen, and stock quantity and value are updated with every movement. The cost of goods sold is determined at the moment of sale rather than at period end.
Is perpetual inventory a management module or a method?
Perpetual inventory is an inventory method. The Perpetual Inventory System applies this method within the General Accounting Management module, so stock, cost and accounting entries are fed by the same movement.
How is it different from periodic inventory?
With periodic inventory, stock value and the cost of goods sold are calculated after the period-end count. The Perpetual Inventory System, which applies the perpetual method, keeps them current with every movement, so stock value and gross profit can also be tracked during the period.
Do I still need to count stock?
Yes. A physical count is how you verify the system balance. With the perpetual method, the count result is compared with the system balance and differences are visible immediately.
Which packages include it?
The Perpetual Inventory System is a feature of the General Accounting Management module and is included in all packages, from NUCLEO to ABM IMPERA.
Can I transfer my existing stock balances?
