What 21 Arbolus experts think of Zellis

NPS scores are predominantly positive, with 65% promoters (NPS 9-10), 25% passives (NPS 7-8), and 10% detractors (NPS ≤6). Renewal intent is robust, with 70% indicating commitment to renew, especially among Influencers and high-spend customers. Stickiness is strong in organizations integrating HR and payroll, but some churn risk is noted due to price and missing features. Key expert themes include payroll accuracy, compliance strengths, automation benefits, and scalability, countered by concerns about integration complexity, UI, and support responsiveness.Overall Customer Sentiment: Positive
