A historythat can't be rewritten.
Every action (each edit, approval, posting, payment and email) is appended to a SHA-256 hash chain. Each entry seals the one before it, the database refuses to change or delete an entry, and anyone with access can verify the whole chain in one click.

How it works
Recorded as it happens,sealed as it's recorded.
- 01
Something happens
An edit, an approval, a posting, a payment, an email, a change to settings or to who can do what.
- 02
It's recorded
Who did it, in what role, to which record, when, and what changed, with the rules that were checked.
- 03
It's sealed
The entry's fingerprint includes the one before it, so no entry can be changed without breaking every one after.
- 04
Anyone can check
Verify recomputes the whole chain and says whether every entry still matches what was sealed.
On every record
Its whole story,one click away.
Every invoice, order, bill and payment shows its own history: who did what to it and when, from the email it arrived in to the payment that closed it.
- Who, in what role
- What changed, before and after
- Rules checked, passed or waived
- From arrival to paid
What's in it
The record your auditorwould ask for.
The database says no
Entries can only be added. An attempt to edit or delete one is refused by the database itself, not just hidden by the app.
Verified end to end
One click recomputes every fingerprint from the first entry to the last, and the check itself is recorded.
Who does what
The Team activity report turns the trail into who did what and when, filterable and exportable.

Rules on the record
Every separation-of-duties check is written as it's applied, including the ones waived under relaxed approvals.
