Shall we begin?

Let's Discuss Bookkeeping Inventory

Bookkeeping inventory is the simple process of keeping records of inventory. It means it tracks the items a business holds that are made available for sale. A bookkeeper keeps records of stock levels, inventory purchases, and the value of inventory at different points in time. If all records are managed properly, businesses will have accurate and up-to-date records all the time regarding the stock.

There are different types of inventories exist in the business space. In retail accounting, we can mainly place them under three broad categories, which are;

  • Raw Materials Inventory: Materials before shifted to production, stay in raw material inventory. Please note that retailers do not account for raw material inventory, only manufacturers do that.

  • W-I-P Inventory: Products that are assembled but yet not ready for a final delivery stay in a work-in-progress loop. Manufacturers also account for these products in inventory.

  • Inventory for Finished Goods: Final products that are meant for sale are accounted for in this inventory. Both manufacturers and most importantly, retailers account for this inventory.

Well, if you draw a difference between bookkeeping inventory vs cost of goods retail accounting process, you can see many things. For example, inventory bookkeeping is beneficial and weighted over other accounting methods for many reasons. First, it directly prevents overstocking and stockout issues. Next, it shows real-time insights into your inventory. Further, it shares the true picture of your inventory and helps you prepare all reports on time.

About Cost of Goods Sold (COGS)

Within a specified period, the number of goods sold and their input and output values are calculated in the COGS method. The direct costs associated with making and selling the products are considered here. It considers various expenses including material costs, labor charges, shipping payments, etc. Note that it does not consider indirect costs like rent, marketing and promotion charges, etc.

There's a formula in place to calculate COGS, let's detail it here.

Cost of Goods Sold (COGS) = Inventory level at the beginning + Purchase made during the time frame – Inventory level at the end

Now, let's understand how's COGS important.

  • Checking gross profit is easy when you know the value of COGS. Just subtract COGS from the total revenue to get the value of gross profit.
  • COGS reflects the accurate price of goods sold.
  • Consider COGS for calculating taxable income as its direct taxable value.

Bookkeeping Inventory vs Cost of Goods Retail Accounting – Keypoint Analysis

Though bookkeeping inventory and COGS accounting may appear to look similar, they have many differences. The main part is they serve different purposes. Have a close look at what they do;

Bookkeeping Inventory COGS Accounting
Focuses on tracking stocks Focuses on goods sold
Tracks the value of stocks on hand Checks the selling amount of stocks/ goods
Reflects business assets Reflects business profit
Does not appear in the income statement Appears in the income statement as an expense

Let's sum up the difference between bookkeeping inventory vs cost of goods retail accounting method.

Inventory bookkeeping helps reflect the real-time value of your stock. On the other hand, COGS represents the value of goods you have sold already. So, now the question is what method you should follow in your accounting practices. To get your answer, we have to understand cost accounting and retail accounting slightly in detail.

The Cost Accounting Method

As the name suggests, the cost accounting method exclusively tracks and allocates costs. This method has been developed as a solution to a specific business accounting issue. The thing is businesses often purchase goods from different vendors at different prices. However, when they set the price of their final goods then the profit from each product appears differently. Therefore, to solve this, the cost accounting method has two options;

  • FIFO (First In First Out): It prioritizes selling the inventory you bought first and puts charge costs accordingly.

  • LIFO (Last In First Out): It prioritizes selling the goods you bought last at first and charging costs accordingly.

The Retail Accounting Method

Like regular bookkeeping practices, retail accounting records, tracks, and prepares the valuation of inventory for retail businesses. Retails gets an estimation of its inventory value without assessing the inventory physically in this method.

Retailers often find this method easier than cost accounting as they do not have to calculate stocks each time after making any sales. This method works on accurate estimation and that's why it is suitable for small businesses.

So, What Method Should You Choose?

After getting the detailed inspection between bookkeeping inventory vs cost of goods retail accounting, hope you have chosen your side. You'll be beneficial if you choose inventory bookkeeping because you're running a small business. However, you must choose COGS accounting if the size of your business operation is quite huge. To help you with accounting, you can choose bookkeeping services through outsourcing. Smart businessmen prefer that mostly.

In general, inventory is a great parameter that informs businesses of the number of goods that have been sold and the number of goods that are still unsold. Based on that information, businesses make decisions and take action.

Choosing inventory bookkeeping simply helps businesses inform the stock information in real time. However, COGS accounting takes a step further as it helps businesses calculate the amount of profit they make selling the goods. Hence, the purpose is different, so choose what you need accordingly.
