Your personal AI Legal Bookkeeper.

Acctivity gives every fee earner an always-on AI Legal Bookkeeper that captures billable work automatically, remembers exactly how each client likes to be billed, and publishes invoices directly to your ledger.

Your billing preferences, remembered.
Your invoices, handled.

Every client has preferences. Every matter has its own billing logic. Acctivity learns exactly how your firm operates, from fee caps and partner rates to how each client likes to be invoiced, and applies that knowledge automatically.

Every fee earner gets the autonomy to finish their own billing the moment work is done.

Without the back-and-forth or the admin.
Revenue recovery

Capture billables in the moment, not at month end.

Most firms lose hours of billable time every week to poor capture.

Acctivity monitors your documents, tasks, calendar and email in real time, logging every billable activity and linking it to the correct matter the moment it happens. Your records are accurate before you leave the office.

“In a busy practice, there's real value in capturing billable activity as the work happens and turning it into structured descriptions a lawyer can review, adjust and finalise quickly.”

“Acctivity connects directly into Xero and can push the work straight through into an invoice. That makes the workflow feel much more practical, because it is not just capturing the work, it is helping move it all the way through to billing.”

“It changes time recording from a retrospective exercise to a contemporaneous one. That means less time lost, more accurate billing, and greater consistency across the firm.”
