Lack of testing cost me at least 2 days of sales
Kind of a warning post, also a reminder to my future self.
In the early stages when you're just trying to find product market fit, this doesn't apply.
But as soon as you start onboarding a few customers. AT THE BARE MINIMUM write automated tests against your billing/subscription logic.
A simple regression bug in my app cost me about 2 days of sales if not more. An avoidable and easy mistake.
The only reason why I caught it was because I was checking in with a customer.
So a couple lessons here:
- Keep in touch with your customers to learn about bugs and pain points
- Contradicting the above - learn to write tests so your customers are the last ones to find bugs
Finding bugs in development is much less expensive than your customers finding it on your live site.
I'm writing my app in a whole new stack that I didn't know the testing tools around, so it wasn't a trivial investment to learn. But I know it will pay in dividends in the long run now that I have actual people using the software.
Anyway, thought I'd share this little tidbit 😅
Learn from my mistakes folks
