Does anyone know of research that can help inform SAAS pricing decisions on whether there are psychological price bands that impact conversion? For example, does $39/month feel closer to $49/month than $59/month (theory is that $50 hits a mental / psychological threshold). Does $20 a month impact conversion compared to $29/month? I have a service that my partner proposed we price at $60/month, but I wonder if that is in the middle of a psychological price band and we should either do $49/month or move up to $99/month (with a couple more features to justify).
Opinions are also welcome . . .
