Legal Services Invoice Template
A legal services invoice has to let a client check every charge on a matter and see where their money went. That means the matter name and number, the billing period, one entry per task with the date, timekeeper, hours and rate, any flat fee with the event that earned it, costs the firm advanced such as filing fees, and, if the client paid an advance, the amount applied from it and what remains. This template lays those out on an ordinary invoice: matter and period, engagement letter and fee basis, time entries by timekeeper, rates by role, flat fees, costs advanced, funds applied from trust and the balance due. The download is an editable HTML invoice with invoice number, dates, a line-item table and totals. Fill it in your browser, then print it or save it as PDF. It is a client-facing invoice, not trust accounting: client trust ledgers and reconciliations are kept in your trust accounting records under your state bar's rules.

Recommended Payment Terms
Bill monthly, or when a flat fee is earned, under the terms in the engagement letter, and repeat them on the invoice. ABA Model Rule 1.5(b) says the basis or rate of the fee and the expenses the client will pay should be communicated, preferably in writing, so the invoice should match the letter. Net 30 is common for business clients. An invoice for work already done is paid to the firm's operating account: that money is the firm's, and Rule 1.15 forbids mixing the lawyer's own funds with client trust funds except to cover bank charges. If an advance held in trust is applied to the invoice, show it as a line and the balance that remains due. Your state's version of the rules is the one that applies, so check it before you copy any wording.

Tax Information
Whether sales tax applies to legal services depends on the state, so check your state's department of revenue rather than assuming either way. In the UK, EU and other VAT countries, a VAT-registered firm charges VAT on its fees, and disbursements paid as the client's agent are often treated differently from costs the firm incurs itself, so follow your tax authority's guidance. For US business clients, the IRS instructions for Forms 1099-MISC and 1099-NEC (revised December 2026) say attorneys' fees of $2,000 or more paid in the course of a trade or business are reported on Form 1099-NEC, and that the usual exemption for payments to corporations does not apply to payments for legal services. That is why clients ask law firms for a Form W-9. InvoiceQuickly applies one tax percentage per invoice and copies saved business and client tax IDs to new invoice PDFs. This is general information, not legal, ethics or tax advice.
Industry context (2026)
Two parts of the ABA Model Rules of Professional Conduct shape what a legal invoice shows, and every state adopts its own version. Rule 1.5(b) says the scope of the representation and the basis or rate of the fee and expenses should be communicated to the client, preferably in writing, so invoices should reflect the rates and increments in the engagement letter. Rule 1.15 governs client money: client funds are kept in a separate trust account, a lawyer may deposit their own funds there only to pay bank service charges, and fees and expenses paid in advance go into trust and may be withdrawn only as fees are earned or expenses incurred. Rule 1.15(d) also requires a lawyer to promptly render a full accounting of client funds on request. That is why this template shows funds applied from trust and the remaining balance, and why the balance due on an invoice is paid to the operating account. Trust accounting itself (ledgers, three-way reconciliation, record retention) is set by each state bar and is done in trust accounting records, not on the invoice. On tax reporting, the IRS instructions for Forms 1099-MISC and 1099-NEC say attorneys' fees of $2,000 or more paid by a business are reported on Form 1099-NEC even when the firm is a corporation.
Worked example
Worked example (fictional firm, client and rates): Alvarez Law PLLC acts for Greenway Landscaping LLC on matter 2026-031, collecting an unpaid $18,400 contract balance from a customer. The engagement letter dated 29 September 2026 sets hourly rates of $300 for the attorney and $110 for the paralegal, billing in 0.1-hour increments, and an advance deposit of $1,500 held in trust, to be applied to fees and costs as they are earned or incurred. Invoice AL-2026-0088 for October lists: 2 Oct, R. Alvarez, attorney: review contract, invoices and correspondence; strategy call with client, 1.4 h at $300 = $420.00; 6 Oct, R. Alvarez: draft and send demand letter, 1.8 h at $300 = $540.00; 7 Oct, J. Kim, paralegal: assemble invoices and delivery records as exhibits, 2.5 h at $110 = $275.00; 20 Oct, R. Alvarez: prepare complaint, 2.6 h at $300 = $780.00; 23 Oct, J. Kim: file complaint and arrange service, 0.8 h at $110 = $88.00; cost advanced: court filing fee, receipt attached, $435.00; cost advanced: process server, receipt attached, $95.00. Fees $2,103.00 plus costs $530.00 = $2,633.00. Applied from trust on 31 October: $1,500.00; trust balance remaining $0.00. Balance due $1,133.00 by 30 November, payable to the firm's operating account. The notes repeat the trust activity for the matter (received $1,500.00 on 29 September, applied $1,500.00 on 31 October) so the client can see exactly how the advance was used.
Common mistakes to avoid
Asking clients to pay invoices into trust
Fees already earned belong to the firm. Directing their payment into the client trust account mixes the firm's money with client money, which Rule 1.15 forbids except for bank charges.
Vague time entries
'Research, 6.5 hours' invites a dispute. Name the task and its purpose so the client can see why the time was needed.
Withdrawing more than the invoice covers
Advance funds may be withdrawn only as fees are earned and costs incurred. Apply no more from trust than the work and costs on the invoice.
Costs mixed into fees
Filing fees and service costs lumped into a fee line cannot be checked. List each cost advanced with its receipt.
Rates that differ from the engagement letter
If rates or increments change, tell the client in writing before the new rate applies, as Rule 1.5(b) expects, and then bill at the communicated rate.
Invoicing Tips
- 1Describe each time entry well enough for the client to check it: 'Draft demand letter to customer re unpaid contract balance' rather than 'Correspondence'.
- 2Bill in the time increment your engagement letter states, and use the same increment on every entry.
- 3Show each timekeeper's role and rate, so the client can see why paralegal time costs less than attorney time.
- 4List costs advanced separately from fees, each with a receipt, and say whether they are pass-through at cost.
- 5If you apply funds held in trust, show the amount applied, the remaining trust balance and the balance due on the invoice itself.
- 6Tell the client clearly that the balance due on the invoice is paid to the firm's operating account, with that account's payment details.

Frequently Asked Questions
What should a legal services invoice include?
The firm's and client's details, invoice number, issue and due dates, matter name and number, billing period, time entries with date, timekeeper, task, hours and rate, any flat fee, costs advanced with receipts, any funds applied from trust with the remaining trust balance, the balance due and how to pay it.
How detailed should legal time entries be?
Detailed enough that the client can tell what was done and why it took that long: the date, who did it, the task and the time in the increment stated in your engagement letter. Vague entries such as 'research' or 'file review' are the most common reason clients dispute legal bills.
Should a client pay a legal invoice into the trust account?
No. Fees already earned and costs already paid by the firm belong to the firm, so the balance due on an invoice is paid to the operating account. Under ABA Model Rule 1.15, a client trust account holds client money, such as advances not yet earned, and the lawyer may not keep their own funds there except to pay bank charges. State rules vary, so follow your state bar's version.
How do I show a retainer or advance on a legal invoice?
List the work and costs at full value, then a line for the amount applied from the client's trust balance with the date, and the balance still due. Rule 1.15 lets a lawyer withdraw advance fees only as they are earned and expenses only as they are incurred, so apply no more than the invoice covers.
Do law firms send 1099 forms for legal fees?
Clients do. The IRS instructions say a business that pays attorneys' fees of $2,000 or more in the course of its trade or business reports them on Form 1099-NEC, even if the law firm is a corporation.
Can I make a legal invoice in InvoiceQuickly?
Yes, the client-facing invoice. Each line is hours times rate with a description naming the timekeeper and task, and matter details and a trust summary go in the notes and terms, which print on the PDF. You can record an amount applied from trust as a partial payment so the remaining balance is correct. Pro can track time with a timer or manual entries and bill selected hours into a draft invoice you review. InvoiceQuickly is still not practice-management software: it does not keep trust ledgers, reconcile trust accounts or produce e-billing files.
