Devi quality assured Vattenfall's sales through follow-up calls to every customer within one week — for correct orders, confident customers and cases resolved before they become problems.
Vattenfall wanted to ensure that every completed sale was correctly delivered and that the customer felt confident in their decision — in an industry where trust is critical.
The need was a structured quality follow-up that verifies every order and catches questions and cases early — before they become problems, regret or churn.
Devi Quality quality assured every sale by calling each customer within one week:
Every follow-up call is both a checkpoint and an opportunity to strengthen the relationship — the customer notices that quality is taken seriously.
The quality follow-up gave Vattenfall confidence that every sale measured up — correct orders, customers who feel seen and cases resolved before they escalate.
The way of working reflects Devi's view of quality: it should be verified, customer by customer. The same principle is behind our certification Trygg Kundkontakt, every year since 2022.
We help companies grow through sales, customer service, recruitment and business development.
