The Verdict
Signal is built for privacy advocates and journalists, with a focus on end-to-end-encryption and group-chats. WhatsApp Business targets small businesses and ecommerce and leads with business-profiles and product-catalogs.
Signal uses custom enterprise pricing, while WhatsApp Business starts at $0/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, WhatsApp Business offers broader built-in capabilities (7 features vs 6), while Signal takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Signal has a slight overall edge — but if access to 2b+ whatsapp users globally matters most to you, WhatsApp Business may still be the right call.
