Smudge, we too have been using WCP for a number of years, and recently switched over to CP.
Why change?
Well, for a number of reasons really. The main one being we have outgrown it. Not outgrown it in terms of numbers, but in terms of its capability to do what we want/need it to do. The developers are no longer developing the program, and it's clear to see times have moved on in terms of accessibility, data storage, etc. the support was simply not there, and my business was locked into WCP, which is not good when it goes down and I can't get any answers.
Why CP?
Having spoken with Rob, the developer, at length, many times, by phone or email, giving him numerous requests and feedback, there was no hesitation for me to sign up.
Rob has bent over backwards to accommodate my requests, tweaking many times, adding features, and benefits, as he was listening to the needs of not only me, but the other testers.
What is so good about CP?
First off, the seamless transition, pulling in all the data from WCP, including schedules, debts, frequencies etc.
It's really intuitive, dead easy to use, and the interface is simple to get to grips with.
It's packed with useful features, and more to come, such as auto invoicing, bulk SMS delivery, mobile app, and more that I can't think of right now. Safe to say there's been a few moments where I've thought "this feature would be handy" and CP already does it.
It allows multiple users, which is great as it can be used on any device with internet access, something WCP couldn't do, so before a holiday, it would take me days of scheduling work, printing sheets etc, whereas now, it's minutes, and then I allocate the worksheet to the operatives, and they can access it on the app. Saves paper, time and stress.
Ok, rambling on a bit now...
Can thoroughly recommend it, and if anyone has any questions, fire away!
