Canadian e-commerce software maker Shopify Inc reported a bigger quarterly loss on Wednesday as operating expenses jumped 80 percent.

Merchants use Shopify’s software platform to design, set up and manage their stores across sales channels including the web, mobile devices, social media and brick-and-mortar outlets.

Total operating expenses in the quarter rose to $77.4 million from about $43 million.

Revenue from Shopify’s merchant solution business more than doubled to $74 million in the fourth quarter ended Dec. 31.

Shopify gets a bulk of its merchant solutions revenue from fees that it charges its clients, or merchants, when their customer orders are processed through Shopify’s payment system.

Revenue in the company’s subscription business, which makes money from the fees Shopify’s clients pay to use its platform, rose 62.9 percent to $56.4 million.

However, net loss widened to $8.9 million, or 10 cents per share, in the fourth quarter, from $6.3 million, or 8 cents per share, a year earlier.

Ottawa-based Shopify, which went public in May 2015, said revenue rose to $130.4 million from $70.2 million.
