Sorry could not resist the click bait headline but sales have gone up that much. Mind you I was starting from a very low base so any increase would be dramatic.
I have a simple web app at https://wordtohtml.net/ we get a tonne of users to our free service but practically zero signups for our Pro product. Based on feedback from the group http://discuss.bootstrapped.fm/t/advice-on-getting-free-users-to-pay-for-a-pro-option-of-a-product/5084/6 I made the following changes.
I merged the free and Pro versions into one. Now Pro features are visible but when a user clicks on them, they get a popup explaining that it is a Pro feature.
I also made the process of signing up for a Pro account a lot simpler. Before the user had to wait for an activation email etc
With these changes, we have had more sales in one month than the previous five months put together. The main lessons are:
Don't hide your features make them as upfront as you can. Very few users where clicking on the Pro features page, you need to show users all the features.
Make the signup process as simple as possible. We only ask for email and password. Users can also sign up with their Facebook or Google account.
Make the payment process super simple. The user clicks the buy button, and we trigger the stripe payment window. It is a 50/50 split between users paying with Stripe and Paypal so make sure to offer both.
My next idea is to have Business plans. At the moment it is just $25 a year for the service, but I am thinking of having two plans Personal for $24 and Business for $72. Both plans are identical in features; I am basing it on the MS Office model where they sell a home version of Office cheaper than the business license. Is this sneaky? Should I offer some extra features in the Business plan? How do you handle business and personal accounts?
If you have a moment, I would appreciate it if you have a click to https://wordtohtml.net/ and let me know if you have any other suggestions.
