Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
A legal invoice should connect each charge to the matter, client, and fee arrangement. Attorneys commonly bill by hourly time, flat fee, contingency fee, retainer, or evergreen retainer. The invoice should match the engagement terms already communicated to the client, including the scope of representation and the basis or rate of fees and expenses.
Use plain matter descriptions, dates, timekeeper names, rates, hours, expenses, and payment instructions. A sample hourly line can read: "March 5, 2026, Draft motion for summary judgment, 2.4 hours, $350 per hour, $840." That level of detail gives the client enough context to review the charge without exposing unnecessary internal strategy.
Attorney invoices are shaped by fee agreements, client billing guidelines, and ethics duties, rather than one federal private-sector invoice form. For United States federal tax records, invoices act as supporting documents that show income sources and transaction amounts. The invoice should also carry standard business details: invoice number, issue date, client name, remittance details, payment terms, and a clear total due.
Legal-specific fields matter more than generic polish. Include the matter name or number, responsible attorney, timekeeper initials where useful, expense categories, retainer application, prior balance, new charges, payments received, and remaining balance. For advance fees and expenses, funds belong in a client trust account until the lawyer earns the fee or incurs the expense.
Retainers need careful wording because an invoice can show earned fees, trust transfers, and remaining client funds in separate places. A clean layout prevents the client from mistaking an advance deposit for revenue already earned. For contingency matters, the signed agreement controls the percentage, expense deduction method, and any expenses the client remains liable for regardless of outcome.
Corporate clients may require legal e-billing instead of a PDF invoice. LEDES 1998B uses 24 pipe-delimited fields, and UTBMS codes classify tasks, activities, and expenses. A firm that serves these clients should keep invoice descriptions and expense categories consistent from the first time entry, because cleanup at billing time creates review delays and write-downs.
A one-off invoice works for a solo matter, a flat-fee engagement, or a final bill after a narrow project. It becomes thin once the firm needs attorney review, write-down tracking, trust balance context, non-billable exclusions, or monthly billing across multiple clients and matters. The durable workflow starts with accurate time and expense capture.
Everhour supports that workflow by separating billable and non-billable time at the project and task level. Admins can set project billing status, mark specific tasks non-billable, use custom task rates, apply member-rate exceptions, and report billable time, non-billable time, billable amount, and cost before an invoice is finalized.

An attorney invoice should include firm and client details, invoice number, issue date, matter name or number, fee arrangement, timekeeper detail, work descriptions, rates, hours, expenses, payments, retainer application, balance due, and payment terms. The invoice should match the fee basis communicated to the client before or within a reasonable time after representation begins.
Private-sector attorney invoices in the United States do not follow one prescribed federal invoice form or national VAT/GST invoice regime. Invoice content is mainly a recordkeeping, contract, client guideline, and professional-responsibility issue. Federal procurement work is different, because FAR 32.905 defines proper invoice fields for federal contract payments.
Retainer activity should separate advance funds, earned fees, expenses incurred, payments applied, and remaining balance. Legal fees and expenses paid in advance must stay in a client trust account until earned or incurred. A clear invoice avoids treating the full advance as currently due revenue and helps the client see how funds were used.
A legal invoice can show hourly fees and expenses when the engagement terms allow those charges and the amounts are reasonable. Keep expenses separate from time entries, describe each charge, and follow the fee agreement. For contingency matters, the signed agreement should state how litigation and other expenses are deducted.
Large corporate clients and legal departments often use e-billing rules to review invoices consistently. LEDES 1998B is a widely used United States legal e-billing format with 24 fields, while UTBMS codes classify tasks, activities, and expenses. These codes help the client route, audit, approve, or reject legal charges.
Everhour lets admins set billing status at the project level, mark specific tasks as non-billable, apply custom task rates, and use member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, which helps firms review a matter before sending charges to a client.
Everhour Billing & Invoicing can turn tracked billable time and expenses into invoices, with line items grouped by project, task, person, date, or another available breakdown. Invoiced time is marked as invoiced, so the same time does not appear again in a later invoice.
Track billable and non-billable legal work before billing day, then review matter totals with clear rates, exclusions, and reports. Everhour gives firms cleaner invoice prep from approved time.
