Home improvement retailer Home Depot recently announced record sales and earnings for the second quarter, driven in part by a massive technology investment. The news came Tuesday, as part of the company’s earnings conference call, where it detailed its specific tech efforts.

Overall, Home Depot’s sales were up 6.6%–reaching $26.5 billion in the second quarter. Of its $5 billion investment plan, store reinvestment was pegged at $2 billion, while technology and online investment came in a close second at $1.8 billion. There were also investments in new stores, international expansion, supply chain, and integration.

A host of new features came out of the technology investment. Online shoppers will have access to Dynamic ETA, which gives better delivery data based on location. Another logistics investment was a project called Sync, that seeks to better coordinate the company’s distribution centers.

Additionally, a new customer order management system called COM has made it into all US stores, and the company is hoping to better sales and inventory management with its algorithms. COM will also be a part of another new effort that will allow a customer to order an item online to be delivered from a local store, shortening the delivery time. It is now available in roughly 700 stores.

Of course, the company invested heavily in its web presence as well. Ted Decker, Home Depot’s executive vice president of merchandising, noted that online traffic is up, driven by mobile.

“Our online business had strong growth in the quarter with double-digit traffic growth and improvement in conversion. Our interconnected retail initiatives continued to evolve to meet the changing demands of our customers. Mobile and tablet are over 50 percent of our traffic and are important tools that our customers use to engage with our products, our stores and our associates,” Decker said.

The company improved product images and customer support chat, and made online checkout easier. A large number of the online orders are now fulfilled through Home Depot stores.

Still, it may be a little more than tech that led to Home Depot’s record quarter. As CBS News pointed out, a jump in the housing market could have also led to more sales at Home Depot and rival Lowes.
