Your calendar and your sent folder know where Tuesday went. Your time sheet knows about four hours of it. The gap is unrecorded time, and in most firms it is found at month end or never.
At 17:30 each day a short email arrives. The 40-minute call on the Mill Lane matter that has no time entry. The eleven emails sent on the probate file, none recorded. The meeting in the calendar at 11:00 that was booked for an hour and has 0.3 against it. Each line has a suggested entry you can accept with one click, or ignore. Most fee earners find close to an hour a day they had forgotten.
Friday at 16:00, a second email. Work in progress per matter. What has been recorded, what has been billed, what is sitting unbilled and for how long. Matters over your threshold are at the top. The 90-day WIP you keep meaning to bill is highlighted every week until you bill it or write it off.
On your billing date the draft bills are prepared. The narrative is pulled from the time entries and tidied into sentences a client will accept. Disbursements are added from the ledger. The draft lands in Xero, QuickBooks or your practice system as a draft invoice, with a note of anything that looked odd, a time entry on a closed matter, a disbursement with no receipt. You review, you send.
It does not write the entries for you. It finds the gaps the same day, while you still remember what the call was about.
This is the kind of thing we build. It runs in your own accounts. How much of yesterday is in your time sheet?
