It has happened twice now that I went well over the limit and had to pay extra. There is only a generic message showing the estimated cost, which is not accurate enough to determine whether to pay extra. There is no hard limit that will stop you from getting invoiced.

You have to be extremely careful when using this tool, otherwise it will cost you a lot of money.

Edit: The tool doesn't even work most of the time. Task don't finish, sometimes it takes serval days to receive the list.

I strongly advise not to use this software. It doesn't work most of the time, and they hit you with additional bills. Very shady company.
