Formal correspondence deserves
better than a shared folder.

Most small companies manage formal letters with whatever is at hand. It works — until it doesn't.

No reference numbers

Trying to track letters without references is chaos. One week in and you're digging through email chains.

Missed deadlines

Response deadlines live in someone's head. Until they don't.

No audit trail

Who sent what, when, and to whom? When it matters, you can't answer.
