If I get a call from a Client, will Selly create an account for that Client?

When a new client calls your Selly voice phone number, when you open the CALLS & TEXTS module and click on the CALLS tab, you should see that client's phone number listed as an unknown contact.

By clicking on that unknown contact, you will the be given an option to either add that client as a new client or to either add their phone number to an existing client already saved in selly as seen above.
