Legal consultants are attorneys, former attorneys, and legal professionals who advise businesses and individuals without acting as counsel of record in litigation. They bill for contract review and drafting, compliance reviews, policy writing, regulatory guidance, expert input on legal operations, and project-based advisory work. Invoices usually go to small businesses, startups, in-house legal departments, and other law firms that need outside help.

Most legal consultants bill hourly, often in six- or tenth-of-an-hour increments, with a stated minimum such as 0.25 hours per task. Flat fees are common for defined deliverables like a standard contract template, a privacy policy, or an entity formation package. Monthly retainers work well for ongoing advisory access, usually with a set number of included hours and a discounted or standard rate for overage. Some consultants use a blended approach: a flat fee for scoped work and hourly billing for anything outside scope. Out-of-pocket costs such as filing fees, court record pulls, and registered agent fees are passed through at cost. Attorneys must follow their state bar rules on fees, trust accounting for advance deposits, and written fee agreements. Non-attorney consultants should not present work as legal advice or representation and should check unauthorized practice of law rules in their state.

Notes: Payment due within 15 days of invoice date. Hours are billed in 0.25-hour increments per the engagement letter dated March 4. Late balances accrue 1.5% interest per month. This invoice reflects consulting services only and does not create an attorney-client relationship beyond the scope stated in the engagement letter.
Ties the invoice to the agreed scope and fee terms, which protects both sides if the bill is questioned.
Clients expect to see what was done and when; vague entries like 'legal work' lead to disputes and write-downs.
Mixed billing is common, so the client should see which items are hourly and which are fixed.
Filing fees, certified copies, and courier costs should be distinguishable from your fees and backed by receipts.
Shows how advance payments were used. Attorneys holding client funds in trust should keep records that match the invoice under their state bar rules.
Clarifies where you are licensed and avoids confusion about whether you are giving legal advice or consulting in a non-attorney capacity.
In-house legal departments and larger companies often cannot process payment without one.
Legal consultants commonly require an advance deposit or retainer before starting, often 25-50% of a flat fee or one to two months of a retainer. Attorneys holding unearned funds should follow trust account rules in their state. Hourly work is usually invoiced monthly or on milestone completion, with payment due in 14 to 30 days; corporate clients may ask for net 30 or net 45. Late fees or interest, often 1-1.5% per month, should be written into the engagement letter, and check your state rules on what is allowed. Payment is typically accepted by ACH, check, wire, or card, and attorneys should be careful about how card payments of unearned funds are handled and recorded.
Define scope, rate, billing increments, expenses, and what is excluded. Many state bars require written fee agreements for attorneys, and even where they do not, it prevents most fee disputes.
Short calls, emails, and document reviews add up. Tracking in 0.1 or 0.25 hour increments avoids under-billing and gives you proof if the client questions an entry.
Use specific descriptions such as 'Reviewed lease amendment and drafted summary of tenant obligations' instead of 'review documents.' Clear entries reduce pushback and requests for discounts.
If a contract review turns into a negotiation or a new matter, tell the client in writing before you do the extra work. This keeps the final invoice from being a surprise.
If you are an attorney, deposit unearned retainers in the proper trust account and move funds out only when earned. Check your state bar rules, since commingling is a common reason for discipline.
Use flat fees for clearly defined deliverables like an NDA, a policy package, or an entity setup. Use hourly billing for open-ended work such as negotiations, ongoing advice, or compliance questions where scope is hard to predict. Many consultants combine both.
Generally no. Routine billing, scheduling, and file setup are treated as overhead. Time on substantive work, such as research, drafting, and client communication, is billable. Check your engagement letter and any applicable bar guidance.
Tenths of an hour (6 minutes) and quarter hours (15 minutes) are the most common. Pick one, state it in your engagement letter, and apply it consistently. A minimum charge per task, such as 0.25 hours, is also common.
In most states, legal services are not subject to sales tax, but a few states tax certain professional or consulting services. Rules vary, so check with your state's department of revenue or a tax adviser.
Send a reminder with the invoice and engagement letter terms, then a formal demand letter. Attorneys should check state rules on fee disputes, since some jurisdictions require or offer fee arbitration before a lawsuit. Small claims court is an option for smaller balances.
Send a Legal Consultant estimate for approval, then turn it into an invoice when the work is done.
