Boosting Field Service Efficiency: Loepfe Transforms Customer Communication with the Lime Connect App

Loepfe Brothers Ltd., the world’s leading manufacturer of electronic quality control systems for textile production, has fundamentally modernized its customer communication.

The Challenge: Lack of Efficient Communication

Communication in the company’s field service was particularly challenging for a long time, as it relied on employees’ private WhatsApp accounts. Without centralized control, standardized data backup, or access to business features of the popular messenger, the potential of digital customer communication remained largely untapped.

In addition, concerns about data protection emerged, since all communication was taking place on the sales team’s private smartphones.

Solution: Implementation of the Lime Connect app

By integrating WhatsApp Business and adopting the Lime Connect app, Loepfe was able to consolidate all customer conversations in India under a single, centralized WhatsApp number. At the same time, field service staff could continue working on the go and respond to customer inquiries directly from their smartphones — now in a professional, secure, and fully traceable way.
The mobile use of the Lime Connect Message Center quickly became part of daily operations and led to significantly shorter response times in customer service.

Result: WhatsApp for Marketing and Sales

Lime Connect not only brought greater efficiency but also opened up new opportunities in marketing. With targeted WhatsApp campaigns, Loepfe was able to promote products and services directly. Even more important, however, was the interaction: customers often responded immediately to messages, enabling the sales team to quickly schedule appointments and further develop leads.

For Loepfe, the introduction of the Lime Connect app represents a strategic step toward modern customer relations. The new solution offers particular benefits for field service staff:

  • Over 340 WhatsApp newsletter subscribers in just six months
  • Open rate of 80% for sent campaigns
  • Significantly improved lead generation through direct interaction after newsletter delivery
  • Efficient appointment scheduling and more targeted customer support
