Invoicing Challenges for Lawyers & Law Firms

Billable Hours Tracking

Law firms bill in six-minute increments (tenths of an hour). A single missed entry or rounding error across hundreds of time entries per month can mean thousands in lost revenue or ethics complaints.

Trust Account Separation

Bar rules require strict separation of earned and unearned fees. Invoices must clearly show when funds are drawn from a client’s trust (IOLTA) account versus billed against earned fees, and errors can lead to disciplinary action.

LEDES Format Requirements

Many corporate clients and insurance companies require invoices in LEDES (Legal Electronic Data Exchange Standard) format. Submitting invoices in the wrong format means delayed payment and frustrated clients.

Lawyers & Law Firms Invoicing Tips

Record Time Entries in Detail

Each time entry should include the date, timekeeper initials, time in tenths, and a specific description of the work performed. Block billing (lumping multiple tasks into one entry) is disfavored by courts and clients.

Show Trust Account Draws Clearly

When drawing from a client’s trust account, show the trust balance, the amount applied to the current invoice, and the remaining balance. This satisfies bar requirements and keeps the client informed.

Bill Retainers with Transparency

For evergreen retainers, show the retainer amount, fees applied against it this period, and the remaining balance. Replenishment triggers should be clear so the client knows when to top up.

Separate Fees from Costs

Legal invoices should clearly distinguish attorney fees from hard costs (filing fees, court reporters, expert witnesses) and soft costs (copies, postage). This level of detail is expected in legal billing.

Frequently Asked Questions

How should law firms track billable hours on invoices?

Record time in six-minute (0.1 hour) increments with detailed descriptions. Each entry should include the date, timekeeper, hours, and a specific task description. Avoid block billing — list each task separately.

What are the trust account rules for legal invoices?

Bar rules require that trust (IOLTA) funds and earned fees are never commingled. Your invoice should clearly show draws from trust, the remaining trust balance, and any amount billed beyond the trust. Rules vary by state, so consult your bar association.

What is LEDES billing and do I need it?

LEDES is a standardized electronic billing format used primarily by insurance companies and large corporate legal departments. If your clients require LEDES, you need billing software that exports in LEDES 1998B or 2.0 format.

How do I bill for a legal retainer?

Deposit the retainer into your trust account. As you perform work, send an invoice detailing the fees earned, draw those fees from trust, and show the remaining balance. When the balance drops below a threshold, request replenishment.
