For sole traders and small businesses on Holded
Your books, coded for you — even when you're not the one touching them

From a pile of invoices to books that are up to date, with no manual work
- 01
It reads every invoice
Certia syncs with your accounting tool and reads every purchase and sales invoice as soon as it appears.
- 02
It learns how you code
It picks up each vendor's pattern from what you've already coded. You don't have to configure rules to get started.
- 03
It applies the right code
It proposes the account code with its confidence and its reason. For vendors it has mastered it codes on its own, and tells you in a daily digest.
It never codes alone until it has proved it gets it right
Every vendor climbs a trust ladder. Certia only starts coding without asking after three clean approvals in a row, and drops back the moment something is corrected.
New vendor
Certia proposes, you decide. Nothing is applied without your approval.
Observing
You've coded invoices from this vendor. Certia is counting clean approvals.
Trusted
Three clean approvals in a row. Certia codes on its own and tells you the next day.
Every decision leaves a trail and none of them is final
Certia works on top of your accounting tool, which remains the system of record. It writes the account code and nothing else, and you can always go back.
Undo any coding
There's no time limit. Certia tells you first what will happen in Holded and in your history.
A permanent record
Who decided what, when, and on what reasoning. The log is never edited and never deleted.
It never deletes or moves money
Certia writes the account code. Nothing else.
