Free Invoice Template for Lawyers

How lawyers usually bill

Hourly against recorded time in tenths of an hour remains the default for litigation and complex advisory. Flat fees are increasingly standard for defined work — formations, wills, immigration filings, uncontested matters. Contingency applies in specific practice areas and comes with its own regulatory requirements. Evergreen retainers replenish as they draw down. Disbursements — filing fees, court costs, experts, couriers, searches — are passed through at cost and are not fee income.

What belongs on a lawyer invoice

Beyond the obvious — your details, the client’s details, a total — these are the fields that a generic invoice template leaves out and that lawyers need:

• Matter name and matter number, on every invoice without exception
• Time entries by date, timekeeper, duration, and a description of the task
• Each timekeeper's rate stated, so blended totals can be checked
• Disbursements listed individually at cost and separated from fees
• Trust or retainer applied, with the opening and closing balance shown
• Any write-off or courtesy discount shown as a line, so the client sees the value given
• Applicable client billing guidelines reference, for insurer-funded matters

Deposits, terms, and when to invoice

Retainers are collected in advance, held per the applicable trust account rules, and replenished when they fall below a stated threshold — the invoice is where that threshold is communicated. Flat-fee work is commonly billed at engagement or split at engagement and completion. Net 30 is customary. Interest on overdue accounts is permitted in many jurisdictions but is regulated, and the engagement letter has to have said so first.

Tax and pass-through costs

Legal services are untaxed in most US states, though a small number tax specific categories. The more consequential rules for a legal invoice are professional rather than fiscal: client funds must be held and accounted for according to your jurisdiction's trust accounting rules, disbursements must be passed through at cost, and fee arrangements must match what the engagement letter and the applicable rules of professional conduct permit. General information, not tax or legal advice — your bar's rules govern.

Line items that prevent arguments

Each of these is a real dispute that a single line on the invoice makes impossible to have:

• "What was that six hours spent on?" — dated entries with task descriptions and timekeeper names answer it without a reconstruction exercise.
• "Why is a partner doing document review?" — showing timekeeper and rate per entry lets the client see delegation, or query it early rather than at the end.
• "How much of my retainer is left?" — a running trust balance on every invoice removes the single most common client question in private practice.
