Pet Supplies Plus

Would you upgrade your current technology or start with something new? 

For Pet Supplies Plus, a full-service pet retailer with over 730 locations in 44 states, this was no longer just a strategic question—it was a pressing necessity. 

Their legacy eCommerce platform was showing its age: expensive to maintain, slow to adapt, and ill-equipped to support modern digital shopping expectations. Meanwhile, without a headless system and operating on disconnected platforms, it added complexity and inefficiency to their operations. 

To stay ahead in a competitive pet retail market, Pet Supplies Plus needed a partner who could execute swiftly, stay within budget, and bring deep expertise in Sitecore and Salesforce. That’s where Horizontal Digital stepped in.

Key highlights:

Despite consistent online revenue growth, Pet Supplies Plus’ old commerce platform was struggling to keep up due to numerous inefficiencies and was becoming costly to maintain.

Lack of personalization & order management: The outdated system couldn’t support tailored experiences . 

Poor site performance: Slow load times, clunky navigation, and frequent site downtime led to frustrated customers. 

Security vulnerabilities: Outdated code exposed potential security risks, as well as lowered digital accessibility scores.
