Ask HN: How would you tell that your app is going to require a subscription?

    Your account is on a plan from prices that we set back in February 2015. Back then, we were 5 people in a San Francisco coworking
    space trying to figure out if what we were building was going to be useful to anyone other than our early adopters.
    
    Over the past year and a half, we've learned a ton about just how valuable Rollbar can be, how it fits into the modern
    software development lifecycle, and where it can go. Tangibly, we have:
    
      * Grown our full-time staff over 3x, from 5 people to 17
      * Hired dedicated support staff
      * Released and improved countless features, including SSO, 2-factor
        auth, and tons of integrations
    
    ... and we're extremely excited to keep working on our mission—to help developers build and maintain software, quickly and
    painlessly—for many years to come. To have the resources to do that, we need to adjust our prices to better reflect the
    value that Rollbar can provide, and we hope that you'll stick with us on this journey.

Offer a full month trial to your existing userbase, and 1 week trial to new users. The Rollbar email is a great example on how transparency can go a long way. Consider offering different pricing plans with different set of features. Power users are more likely to pay more, and casual users can continue using limited features at a smaller price.

Also, as much as I agree with traskjd comment, I don't think it holds true to Brazil. You probably know what I'm talking about. I'm afraid the strategy here must be "price as cheap as you can", unless you are dealing with a very special audience (or with enterprises).

I'm happy to know how this turns out. Consider sharing a blog post with your experience :) Good luck / boa sorte.

I wouldn't expect any medical office to balk at $9/mo . . . if anything you should raise the price, that seems too inexpensive. I'd do three plans $49, $99 and $199 depending on features/levels you can offer or maybe per doctor/staff/patient depending on your app.

Do you have Hipaa style privacy laws regarding electronic medical records in Brazil? That usually commands a premium here so same app for non-medical $99/mo for medical $199/mo.

I think you're pricing too low, if it provides value speech therapists are going to expect to pay for it.

Good luck, let us know how it goes.

I'd also suggest charging more than $9 a month. I appreciate there's a currency difference between the US & Brazil, however that's really not a lot of money. Consider the human support side alone. One question from each customer would likely take months to recover the cost of (and that's after you paid to acquire them, and provide the service).

Just my 2c, but hope it helps!
