How Attorneys Bill Clients
Legal billing conventions differ from most other industries. Time is recorded in small increments, multiple billing rates apply (partner, associate, paralegal), expenses are itemized separately, and ongoing matters require running balance tracking. Our free attorney invoice templates cover all common legal fee structures — from hourly billing to contingency arrangements.
A professional invoice reflects the credibility of your practice. It should clearly communicate fees, expenses, and payment terms so clients understand exactly what they are paying for.
Common Legal Fee Structures
What to Include on an Attorney Invoice
- Law firm name, address, and bar license number — your licensed practice identity
- Client name and case or matter reference — unique identifier for the legal matter
- Billing period — start and end date of the billing period
- Attorney and staff rates — partner rate, associate rate, paralegal rate, etc.
- Itemized time entries — date, task description, attorney or staff name, hours, rate, and line-item amount
- Expenses and court costs — separately itemized at cost: filing fees, process server, expert witnesses, deposition costs
- Retainer balance — previous retainer balance, amount drawn this period, remaining balance (if applicable)
- Subtotal, expenses, and total amount due — clear financial summary
- Payment terms — due on receipt, Net-30, or other agreed terms
