adverbs - Use of 'already' in future tenses

I understand that 'already' is good friends with perfect tenses and it can also be used with the present and the past, but what about future tenses?

I found the following sentences on the Internet:

1. the future perfect: When you arrive, the business will already have been completed.


2. the simple future: When you arrive, the business will already be complete.

I can understand and accept the first one (as it's still the perfect tense) but what about the second? Does it make any sense? If so, can someone comment on it and explain it to me (and possibly give some examples)?

Many thanks!
