We're very flexible and encourage you to work with your client as a freelance Virtual Assistant in whatever way works best for them.
For example, if the client prefers email or phone calls - that's absolutely fine. If the client would prefer not to use the Time etc system because they have another to-do system such as Asana or similar that they already use it's absolutely fine to use that in favour of the Time etc system.
As long as you're adding tasks and time into the system so that you're fees can be accurately calculated then we don't mind how you work with your client.
Finding the client's preferred method of communication is 50% of the battle in ensuring a strong long lasting relationship with a client. If they are easily able to send something through to you to work on then that means more work for you and more work taken off their plate.
