Lengdon vs Firmex

"Done" means the documents are uploaded and the deal team has access.
Most people think
"Done" means both parties reviewed, confirmed, signed, paid, and closed.

Both parties confirmed, signed, paid, and closed — with every gate action permanently on record.

Six-gate enforced close sequence
Firmex has no transaction sequencing. It's a document management platform.
Per-person NDA, individually bound
Firmex NDA management is typically document-centric rather than identity-level access binding.
Bilateral confirmation per gate
Firmex is built around document upload and access grants, not a two-party confirmation requirement.
Append-only audit log
Firmex activity logs are standard records — not append-only or tamper-evident.
Payment gate confirmation
