Le système d’inventaire perpétuel met à jour les registres d’inventaire en temps réel après chaque achat ou vente, à l’aide de systèmes automatisés tels que des caisses enregistreuses, des scanners et des logiciels de comptabilité.
Dans ce système, le compte de stock augmente à chaque achat et diminue à chaque vente, ce qui garantit que le compte de stock reflète toujours les niveaux de stock actuels.
Par exemple, Best Appliances, un magasin d’électronique, a une centaine d’unités de réfrigérateurs en stock le premier mai.
Lorsqu’un client achète un réfrigérateur pour trois mille dollars, le système diminue automatiquement le nombre de stocks d’une unité tout en augmentant le compte bancaire de trois mille dollars.
Ces données en temps réel aident les gestionnaires à prendre des décisions d’achat et de vente plus éclairées.
L’un des principaux avantages du système perpétuel est un contrôle plus strict des stocks.
Cela permet aux entreprises de surveiller les niveaux de stock, en minimisant en permanence les ruptures de stock ou les stocks excédentaires.
Malgré ces mises à jour en temps réel, les entreprises effectuent généralement des inventaires physiques périodiques pour vérifier les niveaux de stock réels et corriger les écarts causés par le vol, la détérioration ou les erreurs de saisie de données.

Q1: How does a perpetual inventory system update stock records?
A perpetual inventory system updates inventory records in real time after each purchase or sale using automated systems like cash registers, barcode scanners, and accounting software. The inventory account increases with purchases and decreases with sales, ensuring records always reflect current stock levels. This real-time data helps managers make informed purchasing and sales decisions.
Q2: What are the main advantages of using a perpetual inventory system?
The perpetual system provides tighter inventory control by allowing companies to monitor stock levels continuously, minimizing stockouts or excess inventory. Real-time visibility enables timely replenishment planning and sales forecasting. This level of responsiveness supports better customer satisfaction and operational efficiency compared to systems relying on infrequent counts.
Q3: Why do companies conduct physical inventory counts if they use perpetual systems?
Despite real-time updates, companies perform periodic physical inventory counts to verify actual stock levels and correct discrepancies caused by theft, spoilage, or data entry errors. These regular checks, typically monthly or quarterly, reconcile recorded inventory with actual inventory and maintain audit compliance, ensuring the system remains accurate.
Q4: What automated tools power a perpetual inventory system?
Barcode scanners, point-of-sale (POS) systems, and inventory management software continuously log purchases and sales in a perpetual system. Each transaction instantly updates the inventory ledger, eliminating delays between when a transaction occurs and when records reflect it. This automation keeps recorded inventory aligned with actual activity.
Q5: How does a perpetual system help with inventory decision-making?
Real-time inventory visibility enables managers to make informed purchasing and sales decisions based on current stock levels. For example, if a retailer starts with 50 units and sells 5, the system immediately reflects 45 units remaining. This immediate insight supports accurate replenishment planning and sales forecasting.
Q6: What happens to inventory records when a sale occurs in a perpetual system?
When a sale occurs, the perpetual system automatically decreases the inventory count by the units sold while simultaneously increasing the cash or bank account by the sale amount. For instance, if Best Appliances sells a refrigerator for three thousand dollars, inventory decreases by one unit and the bank account increases by three thousand dollars instantly.
Q7: How does perpetual inventory tracking benefit high-turnover retail businesses?
Retailers selling high-turnover items like smartphones or televisions benefit significantly from perpetual systems because real-time tracking prevents stockouts and excess inventory. The system's continuous monitoring ensures products are available when customers want them while minimizing capital tied up in overstock, supporting both sales and profitability.
