Support tickets integrated with service monitoring. Around 3 years ago, we started to get a lot of customers for our VoIP tunneling solution, mostly from UAE. Most of these were unfriendly customers abusing our support, so I started to implement a CRM to track "support points". I spend a half year to develop this solution (with lots of other functionality such as service monitoring) and when I finished, there was no any demand for the VoIP tunneling solution anymore :) This is how I wasted half year instead to focus to solutions relevant for our business. Thanks good, we started to have new customers again since last year and actually my CRM/support point tracking software is very useful now, but I still don't think that it worth’s 6 months’ time investment. Conclusion: focus on your main business and don’t spend too much time with automation and other helper software (or hire somebody to do it if your business is big enough)
