Important Notes

* There is a little difference between 'That's all', 'That's it' and 'That's that'. Sometimes you can use 'That's that' or 'That's it' or 'That's all' instead of using 'That's about it/all' where they are applicable interchangeably, but not always.

* We can use 'That's all' in this way also: That's all the money I have in my pocket now. | That's all the items I have arranged for you.

* 'That's it' means whatever you said is all that it was, and 'that's all' means that whatever you said is all and nothing more.
