I cofounded DialPhone three years ago. We have deployed for 200+ UK businesses. Here is what I have learned — and what I got wrong.
What I Got Right
1. All-inclusive pricing wins. We debated tiered pricing for months. We chose flat £24/user with everything included. Our sales cycle is 60% shorter than competitors because there is nothing to negotiate. The price is the price.
2. Mobile app quality is the #1 differentiator. We spent 40% of our engineering budget on the mobile app. Competitors spend 10%. Our app notification reliability is 97%. Theirs averages 82%. Every missed notification is a missed call. Every missed call is a reason to churn.
3. Support speed matters more than support hours. We could have offered email-only support and hired 2 people. Instead we invested in phone support with a 3-minute target. Our NPS is 72. Industry average is 31.
What I Got Wrong
1. I underestimated the receptionist. We designed the admin portal for IT managers. Wrong. The person who uses the system most is the receptionist. We rebuilt the entire admin UI based on receptionist feedback. It took 6 months. Worth every hour.
2. I thought feature count mattered. We launched with 50 features. Usage data showed 8 features covered 95% of daily use. We stopped building features and started perfecting the 8 that mattered: calling, transfer, hold, voicemail, mobile app, recording, ring groups, and auto-attendant.
3. I assumed porting would be easy. UK number porting is a bureaucratic nightmare. Losing carriers obstruct. References get rejected on technicalities. We hired a dedicated porting team. It is our highest-cost department per headcount. But it is the reason 97% of our migrations have zero downtime.

We are not the biggest VoIP provider in the UK. We are not trying to be. We are trying to be the one that small and mid-size businesses recommend to each other — because the product works, the price is fair, and when something goes wrong, someone answers the phone in 3 minutes.
