Reliable and professional support with strong communication in a fast-paced environment.

We brought ExpertCallers on board to handle inbound inquiries, email and chat support, and lead qualification across our global operations at Willis Towers Watson. Managing that volume internally was creating bottlenecks, and the goal was to free up our teams without sacrificing response quality.
Onboarding required some adjustments on both sides before things ran smoothly, but once aligned, they picked up our workflow quickly and maintained the quality we needed at high volumes.
Leads were routed accurately, queries were handled within reasonable timeframes, and coordination across time zones was manageable. Over time, our internal teams shifted focus toward more strategic priorities.
It's an ongoing engagement, and the consistency has held up. Not a flashy partnership — but a reliable one, which for this type of work is what matters most.

Describe your project in brief

At Willis Towers Watson, we engaged ExpertCallers to support inbound customer inquiries, manage email and chat communication, and assist with lead qualification. The objective was to efficiently handle high volumes of client interactions across global markets while maintaining a high standard of responsiveness and service quality.

Their team managed client communications, provided timely responses, and ensured leads were accurately routed to the appropriate internal teams, helping streamline our overall workflow.

What is it about the company that you appreciate the most?

Their ability to maintain consistent quality across a high volume of interactions. Communication was structured and transparent, which made coordination across our global teams straightforward. They didn't need constant oversight once the processes were established.

What was it about the company that you didn't like which they should do better?

The initial onboarding period needed more back-and-forth than I expected — there were a few adjustments to how leads were being categorised before it matched our internal criteria. It wasn't a major issue and was sorted within the first few weeks, but it is worth noting for anyone expecting a fully plug-and-play setup from day one.
