Financial history that maintains itself.
Mezzanine automatically files, organizes, and connects every document to the right payments, entities, and agreements. Everything stays current, searchable, and instantly accessible.
The whole picture no matter your starting point.
Mezzanine links documents and payments in both directions. Open a payment to see its paperwork, or a contract to see every payment made against it and what's still owed.
Nobody has to remember which folder something went in, or search a shared drive for a file name.
Try it Switch between the payment and the contract.

Never lose a version, or track of the latest.
Upload a new version and the old one stays exactly where it was, so you never have to wonder whether the copy in front of you is the latest, or what changed since the one you signed.
Each document keeps:
- Who uploaded each version, when, and a note on what changed
- The current version marked, every earlier one still there to open or download
- Its own view and edit permissions, so a draft stays with the people drafting it
The day you need it.
-
At audit
An auditor picks a payment. You show them the invoice and the signed agreement behind it, from the payment itself.
-
In a dispute
Which version did you agree to, and when did it change? Every version is there, dated, without anyone digging through email.
-
When people change
A new controller inherits the paper trail in the system, not in a former colleague's inbox.
