Service by SELLBYTEL Group.

Customer-oriented. Thrilling. Successful. For 30 years.

Customer satisfaction
Fact 1
Fact 2

Our objective is to secure the greatest possible added value for our clients – through individual solutions in the management of your customers. How? Perfect with absolute precision, always present where you recognize a demand: presales, sales and postsales, customer services or back office solutions. Whatever you opt for, SELLBYTEL Group always supplies you with highly efficient services. Our portfolio is as wide-ranging as your challenges. Hence our success and growth since our establishment in 1988.

Always in view: your success in service.

Service quality: optimized.

SELLBYTEL Group wants everything to run as smoothly as possible for you and your clients. In order to ensure this, our teams work exclusively for your company. Through external and internal benchmarks, we optimize processes and keep the costs low. The results back us up: higher resolution rates, short processing times, increased quality.

Customer satisfaction: maximized.

Continuously optimized service quality ensures constant satisfaction amongst customers. The proof: our very high average value of more than 95% in customer satisfaction surveys.

Revenues and customer value: increased.

Satisfied customers are loyal customers. And they’re happy to purchase again. We take advantage of this satisfaction and loyalty amongst your customers, whenever it makes sense, as the basis for up-selling and cross-selling. This reduces your costs, increases your revenue and, of course, the value of your clients.
