Attorney invoices bill time in tenths of an hour (0.1 = 6 minutes) at $150–$500+ hourly depending on market and practice area, organized by matter with each entry showing date, timekeeper, narrative, hours, and rate. Retainer billing draws against trust (IOLTA) funds — the invoice shows the trust balance, the amount applied, and any replenishment due. Costs (filing fees, service, depositions) bill separately from fees. Flat-fee matters (immigration, criminal defense, estate planning) and contingency cases follow their own documented structures; corporate clients increasingly require LEDES-format e-billing with UTBMS task codes.
Attorney Invoice Template
Reviewed by the Agiled editorial teamUpdated June 2026
Legal billing is the most regulated invoicing in professional services: trust accounting rules with disciplinary teeth, fee-agreement requirements, and clients — from individuals to insurance carriers — who scrutinize every tenth of an hour. The invoice has to show its work: matter-organized entries with real narratives, costs separated from fees, and on retainer matters, the trust ledger math that bar auditors expect to reconcile. This template carries that structure for hourly, flat-fee, and retainer billing. Download it in PDF, Word, Excel, Google Docs, or Google Sheets, or generate a pre-filled version below.

What to include on a attorney invoice
Matter identification
Client and matter name/number on every invoice — and separate invoices (or clearly separated sections) per matter. Mixed-matter bills break both client budgets and your own realization tracking.
Time entries with real narratives
"5/14 — Draft and revise motion to compel; conference with opposing counsel re: discovery dispute — 1.8 hrs @ $325." Date, timekeeper, narrative, hours, rate. 'Legal services rendered' is how bills get cut.
Tenth-hour increments, honestly applied
0.1 = 6 minutes. Block billing (one entry covering many tasks) and routine 0.3s for one-line emails are the two patterns fee auditors flag first.
Costs separated from fees
Filing fees, process service, deposition transcripts, expert charges — their own section, at cost, with receipts available. Many fee agreements and most carriers require the split.
Trust accounting on retainer matters
"Trust balance before invoice: $4,200. Applied to this invoice: $3,150. Remaining: $1,050. Replenishment due per agreement: $2,000." The ledger paragraph that keeps the bar happy and the client informed.
Timekeeper rates by person
Partner, associate, and paralegal time at their agreed rates, identified per entry. Paralegal time is billable; secretarial time is not — the line audits will check.
Fee-agreement consistency
Rates, increments, and cost treatment matching the engagement letter exactly. The invoice is evidence — in a fee dispute, it gets read against the agreement line by line.
Typical attorney billing (U.S., 2026)
| Item | Typical range | Notes |
|---|---|---|
| Solo / small firm hourly | $150 – $400 | Market-dependent |
| Mid/large firm partner | $400 – $1,000+ | |
| Paralegal time | $75 – $200 / hr | Billable when substantive |
| Flat fee — uncontested divorce | $1,500 – $5,000 | |
| Flat fee — estate plan package | $1,500 – $6,000 | Will/trust complexity drives it |
| Flat fee — DUI / misdemeanor defense | $2,500 – $10,000 | |
| Contingency | 33 – 40% of recovery | Costs per agreement |
| Evergreen retainer replenishment | Per engagement letter | Triggered at threshold |
Rates vary enormously by market and practice area. Trust accounting, fee agreements, and fee-splitting are governed by your state bar's rules — they control over anything here.
How attorney billing actually works
Hourly matters: the monthly bill cycle
Bill monthly, promptly — invoices sent ninety days after the work bill against a memory nobody has. Each matter's invoice carries the period, entries in tenths with narratives, costs in their own section, and the running matter total against any budget. Insurance defense and corporate clients add their billing guidelines (no block billing, task codes, staffing rules) and increasingly require LEDES e-billing; bill against the guidelines from day one, because appeal-and-resubmit cycles consume the margin the file had.
Retainers and trust discipline
The retainer sits in trust until earned — the invoice is the instrument that earns it. Each bill shows fees incurred, the trust application, the remaining balance, and the replenishment trigger from the engagement letter (evergreen retainers replenish at a stated floor). Never apply trust funds without an invoice, never let the trust ledger and billing system diverge, and refund unearned balances promptly at matter close. Trust violations are the most common path to discipline — the invoice paper trail is the defense.
Flat-fee and contingency structures
Flat-fee matters invoice the fee with its scope stated ('uncontested divorce through decree; contested proceedings billed hourly per agreement') and milestone payments where the agreement splits them — with state-bar rules governing when flat fees may be treated as earned. Contingency matters generate no fee invoice until recovery, but cost tracking runs the whole time: a settlement statement at resolution shows the recovery, the percentage fee, itemized costs, liens, and the net to client — the most-read invoice in all of law.
Invoicing mistakes that cost attorney professionals money
Vague narratives
'Attention to file — 2.0' survives neither client scrutiny nor fee-petition review. Narratives state what was done and in connection with what — specific enough to justify, concise enough to read.
Block billing
One 6.5-hour entry covering research, drafting, and calls gets discounted by carriers and courts alike because nothing in it can be evaluated. One task, one entry.
Trust sloppiness
Applying retainer funds without an invoice, or letting the bill's trust math drift from the IOLTA ledger, is a disciplinary referral waiting for an audit. The invoice's trust paragraph must reconcile to the ledger, every bill.
Mixing costs into fees
Filing fees buried in fee lines distort both numbers and violate many fee agreements. Costs at cost, separately, receipts available.
Billing late
Legal bills age worse than any other professional invoice — the matter's urgency fades and the narrative reads colder every month. Bill monthly while the work is fresh and the client remembers why it mattered.

FAQs
How do attorneys bill their time?
In tenths of an hour (0.1 = 6 minutes), with each entry showing the date, timekeeper, a narrative describing the task, hours, and rate. Invoices organize by matter and bill monthly. Hourly rates run $150–$400 at solo and small firms, and $400–$1,000+ for partners at larger firms.
How does a retainer appear on a legal invoice?
As trust accounting: the invoice shows the trust balance before billing, the amount applied to the current fees, the remaining balance, and any replenishment due under the engagement letter. Retainer funds belong to the client until earned by invoiced work — applying them without a bill, or letting invoice math diverge from the IOLTA ledger, invites bar discipline.
Why are costs billed separately from fees?
Filing fees, process service, transcripts, and expert charges are client expenses advanced by the firm, not legal services — and most fee agreements, carriers, and courts require them separated and billed at cost. The split also keeps the fee number honest for budget tracking and fee-petition purposes.
What is block billing and why does it matter?
A single time entry lumping multiple tasks — 'research, draft motion, calls — 6.5 hrs.' Courts, fee auditors, and insurance carriers discount block-billed entries because no individual task can be evaluated for reasonableness. One task per entry is the rule that protects realization.
What is LEDES billing?
An electronic billing format (with UTBMS task and activity codes) that corporate legal departments and insurers require for invoice submission. Each time entry carries standardized codes so client systems can audit automatically. If your clients require it, bill to their guidelines from the first entry — resubmission cycles are where the file's margin dies.
How do contingency fee invoices work?
No fee bills until recovery. At resolution, a settlement statement itemizes the gross recovery, the contingency percentage (typically 33–40%), case costs (which, per the agreement, deduct before or after the fee calculation), medical or other liens, and the net to client. Cost tracking throughout the case is what makes that statement defensible.
