What is a modern and convenient CRM?

Question

PHP

Good afternoon!
Actually, last night puzzled. I really don't want to write everything from scratch.
What you need:
- A database of clients by client cards (in general, the "Card ID" field can be added by yourself)
- The ability to send SMS (well, you can also tweak it yourself)
- Different access levels (Admin, Boss, Manager, Slave)
- So that all this not only works well through the computer browser, but also from the iPhone, the slave can add the income of the dough from the client and the consumption of the dough for related products, and the boss can watch beautiful statistics.
Actually, what is suitable for these requirements? Or is it easier to write it yourself?
