See everything that happened to an order
Who sent it, what changed, what the supplier said, and when.
What this is for
“Who changed this and when?” used to have no answer. Every purchase order now keeps a history — raised, sent, amended, received, checked, cancelled — including the supplier's own answers from their link.

Step by step
- 1
Open any purchase order and scroll to its history.

- 2
Each entry says what happened, who did it, and when — in plain English rather than field names.
- 3
Entries marked as the supplier came from their link. Entries marked automatic were done by Sign OS, such as an email going out.
- 4
Amendments list what actually changed: this line went from 10 to 14, that price went from $8 to $9.
Tips & gotchas
- The history is never edited or deleted, only added to. That is the point of it.
- It records emails that failed as well as ones that sent — “could not email [email protected]” is the useful line, not silence.
