Find the paper behind any payment.

Find the paperwork behind any payment, and every payment behind any contract. Every document keeps its full version history, so nothing is overwritten and nothing goes missing.

From the payment to the paper, and back

Attach an invoice or a contract once and it is linked both ways. Nobody has to remember which folder it went in, or search a shared drive for a file name.

Open the payment and the invoice and contract are on it. Open the contract and every payment made under it is listed, with what is still due.

Try it Switch between the payment and the contract.

Old versions, kept

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.
