Hot on the heels of the pricing experiments article the other day, here's a practical case study by Patrick McKenzie, discussing advice that he gave to Server Density (who is one of our happy clients at GrantTree!), that led to a doubling of their revenue per customer.
The changes involved moving from variable pricing to fixed plans, and targeting their pricing more at the corporate end of the market, but you have to read the article itself to get the benefit of Patrick's insights. It's not about the answer, it's about the thinking process behind the answers. On that note, Patrick's comments on Hacker News, answering specific questions from the HN audience, are incredibly valuable too.
I wish I'd read this 5 years ago when I was starting Woobius. If you're starting a B2B SaaS business, read this attentively.
