Generate invoice →What to include on a legal invoice
Legal invoices need to be precise. Your client is paying for your time and judgment — they deserve to see exactly what they're being billed for. Vague entries like "legal research — 3 hrs" invite disputes. Specific entries build trust.
Your name, bar number, and firm name
Include your bar admission state(s) and bar number. For solo practitioners, your name and bar number establish you're a licensed attorney — not just anyone sending an invoice.
Client name and matter description
Identify the client and the specific legal matter: 'Smith v. Jones — Contract Dispute' or 'Wilson LLC — Asset Purchase Agreement Review.' If you bill one client for multiple matters, each should be a separate invoice.
Invoice number, date, and billing period
Sequential numbering and a clear billing period (e.g., 'Services rendered: May 1–31, 2026') make your invoices easy to reconcile against retainer payments.
Itemized time entries
Each time entry should have a date, a specific description of the task, and the time spent (in 0.1 or 0.25 hour increments). 'Reviewed and marked up purchase agreement, sections 3–7' is billable. 'Legal work' is not.
Your hourly rate
State your rate clearly. If different timekeepers (associate, paralegal) worked on the matter, list each person's name, title, hours, and rate.
Disbursements and expenses
Court filing fees, service fees, travel, expert witness fees, and copying costs are passed through to the client. List each disbursement with the date, description, and amount.
Retainer balance (if applicable)
Show the original retainer, fees applied this period, and the remaining retainer balance. Transparency here is essential for trust and compliance with bar rules.
Payment instructions
Trust account details (if billing from retainer) or direct payment instructions. Note your payment terms — legal invoices are typically Net 30.
Legal invoice examples
Hourly billing invoice
The most common legal billing model. Each time entry is dated, described, and timed to the tenth or quarter hour.

Flat-fee invoice
Flat fees are common for transactional work — LLC formations, contract drafting, simple wills. The invoice is simpler but must clearly describe what's included and what's not.

| Note: additional state filings, EIN registration, and banking introductions are not included | |
| Total Due | $1,369.00 |
Retainer billing invoice
When billing against a retainer, show the retainer balance clearly. Bar rules in most states require accounting of how retainer funds are applied.

5 invoicing rules for lawyers
Write time entries you could defend in a fee dispute
Every entry should answer: what did you do, on what date, for how long? 'Drafted motion for summary judgment, Section IV — statute of limitations argument, 2.4 hours' is defensible. 'Worked on case' is not.
Never let fees grow in your trust account
Bar ethics rules in most states prohibit holding unearned fees in a trust account without proper accounting. Bill promptly — monthly is standard — and transfer earned fees out when they're earned.
Send invoices on a consistent schedule
Monthly billing is the legal industry standard. Bill on the same day each month so clients can predict when invoices arrive and budget accordingly. Irregular billing creates sticker shock.
Define 'included' and 'not included' in flat-fee matters
Every flat fee engagement should have a scope of work in writing. On the invoice, restate what's included and explicitly note what falls outside scope. This prevents scope creep and fee disputes.
Require a retainer before starting any significant matter
Ask for a retainer upfront for any matter expected to exceed 5 hours. This protects you financially and signals to the client that they have skin in the game. State your replenishment threshold in your engagement letter.
Frequently asked questions
Do I need special legal billing software?↓
Not necessarily. Many solo attorneys and small firms use simple invoice tools rather than expensive practice management software. The key is itemized time entries, retainer accounting, and consistent billing — you don't need Legal Tracker or TimeSolv to achieve this.
What's the difference between a retainer and an advance fee?↓
A retainer is typically paid to secure your availability (earned upon receipt). An advance fee is prepayment for future services and must be held in trust until earned. The terminology varies by state bar rules — make sure your engagement letter and invoices use the term your state recognizes correctly.
Should I charge for emails and short calls?↓
Yes, if they're substantive. A 0.1-hour entry ($35 at $350/hr) is appropriate for a client email that required legal judgment. What you shouldn't bill for: checking voicemail, admin tasks, or time you can't specifically describe. The ABA Model Rules require that fees be 'reasonable' — nickel-and-diming erodes trust.
Can I charge a contingency fee and still send invoices?↓
Contingency fee arrangements don't involve invoices during the case. The fee is earned at resolution. However, you should still track time internally (for your own records) and send the client a statement of costs (disbursements) at the end. Some attorneys send periodic 'status updates' showing hours worked without billing — it demonstrates value.
What do I do when a client doesn't pay?↓
First, send a formal demand letter referencing your engagement letter and invoice. If that fails, you may be able to file a charging lien against any recovery in the case. For non-payment on completed matters, small claims court is available for amounts under your state's threshold. Check your bar's rules on fee arbitration — some states require offering it before suing a client.
