Willow
Advanced Pre-Bill Review & Approval
Willow gives your billing team and your attorneys one place to review, adjust, and approve every bill before it leaves the firm — with the timekeepers who know the work, and the fixes that protect realization made while there's still time to make them. Native to Clio.
What Willow Does
Structured Pre-Bill Review
Review every draft bill line by line — adjust hours, mark entries no-charge, and exclude what should never leave the firm — before the invoice goes out, not after a write-down comes back.
Timekeeper Collaboration
Bring the attorneys who did the work into the review. Timekeepers weigh in on their own entries, so corrections happen with the context only they have — not guessed at by billing after the fact.
Written Back to Clio
Every adjustment flows back to Clio automatically — one source of truth, no re-keying, and no drift between what you reviewed and your system of record.
Realization, Protected
Catch the unbilled time, thin descriptions, and errors that quietly erode realization while the bill can still be fixed — so more of the work your firm did becomes revenue it keeps.
Fix it before it's billed
The cheapest write-down is the one that never happens. Willow moves the review upstream — to the moment the bill can still be corrected — so problems are caught by the people who can fix them, before the invoice ever goes out.
What Willow Moves
Post-bill write-downs
Issues are fixed at review, not conceded after invoicing
Realization
More reviewed, corrected work turns into collected revenue
Billing-cycle time
Approvals move instead of stalling in email threads
Attorney participation
Timekeepers engage with bills they can actually shape
The people who did the work, in the bill before it goes out
Too often, pre-bill review is a billing coordinator interpreting entries alone, days after the work happened. Willow brings the timekeepers into the same review, so hours and descriptions are corrected with real context — and billing owns a process instead of a guessing game.
Front-of-house stays close to the matter; the back office keeps control of the bill.
One review, one source of truth
Adjust hours, mark no-charge, exclude lines, and leave notes for the timekeeper — all in one place, with every change written straight back to Clio.
No spreadsheet markups, no re-keying, no version drift between your review and your system of record.
