A legal invoice is read by a client who is already anxious about the cost, so it has to show exactly what was done, by whom, for how long and at what rate, with costs separated from fees and the retainer applied in plain sight. Bar rules in most states also require the invoice to be clear enough that a client can question any entry. This template does that on one page for a small practice: matter, time entries in tenths, flat-fee lines, costs, retainer credit and the trust balance remaining.
Free, fillable, US Letter. No email, no sign-up. Fill in the firm details once. For each matter change the client, the matter line and the entries.
What the PDF looks like. The hints in the line table show the lines a attorney typically bills; type over them.
“Research and drafting, 6.4 h” gets questioned and, in some fee disputes, cut. One entry per task with its own time.
Filing fees, process servers and copies are reimbursements, not fees. Separate section, receipts available.
The client paid $3,000 up front and the invoice shows $2,100 due with no credit. They call. Show the retainer applied and the trust balance remaining.
Lines a typical job produces. Labor and materials are separate, and anything already paid is a negative line so the total is the balance due.

Most state bar rules require that a bill be clear enough for the client to understand what was done: the matter, each service with its date and time, the rate, costs separated from fees, and how any retainer was applied. Several states require itemized time entries on request.
Six-minute increments are the profession's standard and what clients and courts expect. Billing in quarter hours on a legal invoice invites a fee dispute; billing in tenths with a task per entry rarely does.
Bill the full fees and costs, then a negative line “Retainer applied from trust”, then a note with the trust balance remaining. The client sees the work, the credit and what is left in one glance.
Yes, at the paralegal rate, on its own entries with the timekeeper's initials. Clerical work (scheduling, copying) is usually overhead and should not be billed as paralegal time.
Due on receipt or Net 15 for hourly matters, with replenishment of the retainer. Flat-fee matters are often billed half on engagement and half on completion.
