What counts as an ÄTA
Ändringsarbete: the contracted work is changed. Tilläggsarbete: work is added that wasn't in the contract. Avgående arbete: work is removed (a deduction).
All three are billable adjustments to the contract sum — but only if they're notified and documented correctly.
Notify without delay, or you can lose the right
Under AB 04 / ABT 06 (chapter 2), an ÄTA must be notified to the client 'utan dröjsmål'. Notify too late and the client can dispute it, and the claim can lapse.
So the moment a change is agreed — even verbally — put it in writing. The template below does exactly that.

The ones you never wrote down
The template fixes the ÄTA you catch. The real leak is the ones nobody logged — the verbal orders on site that never reach any document.
ÄTA-koll reads the byggmötesprotokoll and emails you already have and pulls out the billable change orders you missed, so they don't leak off your margin. You can try it free on your own protocol.
