Because of this business model difference, the cost structure is also completely different. Most of Target's expenses are in cost of goods sold because it has to pay for the inventory it sells. DocuSign's cost of goods sold is a lot lower as a percentage of revenue because it doesn't have many direct costs related to each sale.
Operating expenses are the opposite. Target pays for the overhead it needs to keep going, while DocuSign is investing in overhead. It paid $400 million in this quarter alone on research and development and sales costs. It is plowing all its gross profit into future growth, and the operating loss reflects that.
