Your bills should contain a section itemizing each task or activity performed, including date, amount of time expended (preferably in fractional hourly format, e.g., 0.25, 1.25, 0.4), and a clear and concise phrase or clause elucidating—in plain English—what work was done, what issues were addressed, and whether these issues were resolved or are still pending. Your bills should also contain another section enumerating costs and fees associated with particular tasks or activities, such as court costs, petition fees, tolls and mileage costs, federal fees for filing patent or copyright applications, Internal Revenue Service fees, etc. To facilitate client reimbursements, receipts for payment of such government fees and costs should be attached to your bills, as appropriate.
Of course, as with virtually any form of attorney communication to clients, your invoices or billing statements should include appropriate disclaimers of confidentiality and/or attorney-client privilege. And if you’re sending these bills electronically, they should be protected via encryption.
Your clients will appreciate routinely receiving case status reports and progress recaps integrated into regular billing. And remember: Clients are more likely to pay promptly for legal services if they actually understand what they are paying for.
