Alright. Now let's discuss a couple more issues with inventory at the end of an accounting period. Let's check it out. Alright. So whether you're using a perpetual system or a periodic system, all companies are going to have to determine inventory at the end of the period, right? They're going to have to know how much inventory is on hand to put it on their balance sheet and report it. So, what do they do? Well, we're going to have a physical count. They're literally going to go into the warehouse and physically count the inventory and see what's there, right, and this is the inventory count that happens at the end of the period. So they're going to count the goods, measure the goods, if they have to weigh the goods to see how much weight they have left of that good, whatever it might be.
So in the perpetual system, we're going to see that the count should confirm our inventory balance in the accounting records. Right? Because in a perpetual system, we're constantly updating inventory. We're perpetually updating it. So when we count the inventory in the warehouse, it should match up with the records, right? And we could adjust any discrepancies, right? Maybe we count and there's something missing. Well, that could be some waste, it could be shoplifting or maybe even employees stealing from you, right? And there's going to be ways to deal with all of that, but we don't really talk about it in this course. And then in a periodic system, the physical count is necessary. Remember that a periodic system, they only update the inventory account at the end of the period, right? They keep track of how much they purchased, they keep track of all sorts of things like that, but then at the end of the period, they physically count the inventory and back into the cost of goods sold. Okay? So in a periodic system, this physical count is necessary. Every time you see a problem about a periodic inventory, they have to tell you the ending inventory because of this physical count. Okay? So that's the physical count right there.
Why don't we pause right here and then we'll talk about the next issue related to the end of period inventory, alright? Let's check that out in the next.
