suffice (it) to say
In short; in summary; it is enough to say. Often followed by "that." I won't go into the details of our conversation, but suffice it to say that Bob won't be coming back on Monday. There were a lot of unexpected hurdles in the application process, and the whole thing turned out to be a lot more complex than we anticipated. Anyway, suffice to say, we were granted planning permission for the new office in the end.
suffice (it) to say (that)...
(formal) used for saying that you could say much more about somebody/something but you do not want or need to: I won’t tell you all that was said at the meeting. Suffice it to say that they approved our plan. Suffice it here means ‘it is enough’.
