Another method, usually the fallback for beginning sellers, is to simply count the inventory that you have at year end. If you know how much you spent for products to sell throughout the year, you can just subtract out the ending inventory amount to come up with the cost of goods sold throughout the year. For example, let’s say that you have spent $36,000 throughout the year for products to sell. However, you have an ending inventory of $10,000. That means your actual cost of goods sold is $26,000 ($36,000 minus $10,000).
