* AiSensy's prices are in US dollars, so rand figures are estimates at today's exchange rate. Paying for a year up front lowers AiSensy's plan prices (10% off); both sides here use monthly billing. Prices change, so check AiSensy's own pricing page before you decide. Spotted something out of date? Email support@whats-hub.co.za and we'll fix it.
