Sort and Track Your Books

Sorting Your Books

Techniques for sorting and Tracking items:

Sorting books is a crucial step in the operations process that can help you improve processing and shipping efficiency while reducing costs. There are various methods for sorting items, including sorting by price, location/client, seasonality, condition, potential profitability, or combination of each.

Cost of Goods Sold (COGS)? 

As a small business owner, keeping track of your financials is essential, especially when it comes to tax season. One important aspect of your finances that you need to pay attention to is the Cost of Goods Sold (COGS). COGS is the direct cost of producing or purchasing the products that you sell, and it is subtracted from your revenue to calculate your gross profit. To be prepared for tax season, it is crucial to keep track of your COGS throughout the year, and one way to do that is by arranging and processing books by price. In this article, we will explore the various methods to track COGS efficiently and predictably.

What is the Cost of Good Sold?

COGS is the direct cost of producing or purchasing the products that you sell. These costs include the cost of materials, labor, and any other direct expenses related to the production or purchase of the goods. For instance, if you sell books, the COGS would include the cost of the books themselves, shipping and handling fees, and any taxes or tariffs you paid to get them. COGS is essential for calculating your gross profit, which is the revenue you earn minus the direct costs of producing the goods. Knowing your COGS allows you to price your products appropriately, and it also helps you keep track of your profits and losses.

Why is Tracking COGS Important?

Tracking COGS is essential for several reasons. First, it helps you understand your business's profitability. By subtracting your COGS from your revenue, you can calculate your gross profit. This metric is crucial because it indicates how much money you have left after paying for the direct costs of producing or purchasing your products. Second, tracking COGS can help you price your products appropriately. By knowing your direct costs, you can set prices that are competitive and profitable. Third, tracking COGS can help you make informed decisions about your business. For instance, if you find that your COGS are too high, you may need to explore ways to reduce your costs or increase your prices.

How to Track COGS Efficiently and Predictably

One way to track COGS efficiently and predictably is by arranging and tracking books by price. You can do this by embedding the price paid in a custom SKU as you list the books. A Stock Keeping Unit (SKU), is a unique identifier that helps you keep track of your inventory. By adding the price paid to the SKU, you can easily calculate your COGS at the end of the year. For instance, if you paid $5 for a book, you can create a custom SKU to indicate that you paid $5 for that particular book. You can create custom SKUs while listing using software like Bulklister.  


Additionally, you can sort your books by seasonality to maximize their selling price. For example, textbooks tend to rise in price during specific times of the year, such as textbook season, which usually occurs in August, January, and June corresponding to the beginning of school semesters. If you hold onto these books and wait to send them to Amazon until right before the textbook season, you may be able to sell them at a higher price, resulting in a more significant profit.

When organizing your books by seasonality, consider using a custom SKU with a seasonal identifier or a specific location to keep track of your inventory. If you have a consignment agreement with a client, documenting location or client ID can help you understand more about your clients or locations. These insights can help you make informed decisions about your inventory, pricing, and sales strategy.

Potential Profit/Weight 

In order to minimize shipping costs and maximize profits, it can be beneficial to hold off on sending heavy or low-value books until they can be included in a more suitable shipment. Shipping heavier books can lead to increased costs, which can ultimately reduce profit margins. By waiting until a more opportune time to ship these books to a warehouse closer to your location, you can optimize your shipping strategy and save money in the process. Similarly, books with a low potential for profit can be categorized as heavy or low-profit and set aside to be shipped at a later time.

To make more informed decisions about which books to send and when it can be helpful to sort your inventory by weight or potential profit. This allows you to prioritize which books to send based on their profitability and shipping costs. By adopting this approach, you can work more efficiently with heavy or low-value books and ensure that shipments are only sent to local warehouses where the cost of shipping is more reasonable.


Keeping track of clients can provide valuable insights into client behavior and inform business decisions. By measuring location performance metrics, you can gain a better understanding of how your business is performing in different areas and make adjustments accordingly. If you have a consignment agreement with a client, it is crucial to know when their books sold and at what price to calculate the amount due to them accurately.

To track this information, you can use a custom Seller Stock Keeping Unit (SKU) that includes a client or location ID. By assigning SKUs to each location, you can easily monitor and track sales performance for each individual client. This allows you to identify areas of strength and weakness and make data-driven decisions to improve your business.

In addition, tracking location can provide valuable insights into customer behavior and preferences. By monitoring sales trends in different locations, you can better understand what types of products are in demand in specific areas and adjust your inventory accordingly. This helps you to optimize your business strategy and improve your bottom line.

Overall, documenting the location and tracking location performance metrics can provide a wealth of information to inform business decisions and improve overall performance. By using custom SKUs to track client and location information, you can easily monitor sales performance and make data-driven decisions to grow your business.


Tracking inventory is an essential aspect of managing any business. By keeping tabs on your inventory, you can gain valuable insights into your business operations and make data-driven decisions to improve your strategy. The insights gained from inventory tracking can help you optimize your operations, adjust to changing market conditions, and ultimately improve your bottom line.

There are several tools you can use to track your inventory, including Spreadsheets, Project Management Software, and Note Apps. Google Sheets, Excel, and Slack are some popular examples of these tools. By using these platforms, you can track inventory levels, monitor sales trends, and forecast demand to ensure that you always have the right products in stock to meet customer demand.

Tracking inventory can also help you identify inefficiencies in your business processes and streamline your operations. By identifying slow-moving or excess inventory, you can make adjustments to your purchasing and stocking strategies to minimize waste and reduce costs.
