For the complete sentence, this is one possible example: If all is OK, we can finalize the purchase.Please give us the complete sentence, and explain the situation in which you would use it.
I think it isn't idiomatic because "all" is too general. What does "all" mean? Everything in the universe?Is it correct to say "If all is OK, you can..." or is this not very idiomatic?
Meaning: you are asking about any problems with this transaction.If all is OK, we can finalize the purchase.![]()
