What billing and costing services do you use as a freelancer?

Question

Freelance

Hello,
this question is part of a study of our freelancing needs, which will greatly help in the development of my pet project.
It would be cool if you can give me a couple of minutes and give me any feedback.
it is very interesting to hear your opinion on the current realities of the market:
- how do you bill your customers?
- Are there any problems / inconveniences with this method?
- Do you have a handy tool for keeping track of your personal/work finances?
If you have an opinion that must be expressed, but you are too lazy to write, we can talk on Skype alex_a_fedosov
Thank you!
