Inventory/ Periodic Versus Perpetual
Periodic Inventory System

Info
Periodic inventory counts (such as once a month, or at the beginning and end of each year), and does not have an accurate record of the inventories in between these points
This system does not keep continuous, moment-to-moment records of inventories. Records are updated periodically – meaning, at certain points in time – when actual counts are done.
Perpetual Inventory System
Perpetual means continuous. This is a system where a business keeps continuous, moment-to-moment records of the number, value and type of inventories that it has.
OCi Accounting system – where each item of inventory is linked to the accounting entries – creates a perpetual system. Inventory levels are automatically decreased as soon as the invoice has been entered and completed at the till.
