What to include on a legal invoice

A legal invoice carries more weight than a standard bill. Clients scrutinise it, costs assessors may review it, and in most jurisdictions it’s the document that authorises you to draw money out of trust. Getting the structure right protects the fee and the file. Alongside the usual invoice fields, a legal invoice may require specific elements that make additional customization extremely handy.

1. Billable time increments

Most firms bill in tenths of an hour: six-minute units, recorded as 0.1, 0.2 and so on. Some bill in quarter-hour units instead. Either is defensible; what matters is that the increment is stated in your costs agreement and applied consistently, because a client comparing two invoices will notice if the same task takes 0.2 one month and 0.5 the next.

Three things make time entries hold up:

Describe the work, not the category.
Avoid block billing. Rolling six
Record contemporaneously. If you’re rebuilding your system, our guide on how to track billable hours covers the methods that work for small practices.

2. Retainer vs. hourly billing

Hourly billing is straightforward: time entries at agreed rates, totaled for the period. The invoice is the complete record of work done.

A retainer as an advance payment is money the client pays up front against fees not yet earned.

A retainer as a recurring fee, often billed monthly as a subscription, for ongoing availability or a defined scope of work.

Whichever model you use, the invoice should match what the costs agreement says. Mismatches between the two are where fee disputes start.

3. Trust and client account handling

Trust money is the client’s, not the firm’s, and it stays that way until you’ve earned it. In practice, that means the invoice comes first: you issue a bill for work performed, then transfer the corresponding amount from the trust or client account to your general account. Drawing funds before billing, or for more than the invoice covers, is a breach in most jurisdictions regardless of intent.

To keep the record clean, show trust activity as its own block, separate from the fee summary:

Trust balance held at the start of the period
Disbursements paid from trust during the period
The amount of this invoice being applied from trust
Trust balance remaining

4. Disbursements

List court and filing fees, expert reports, transcript costs, searches, travel and courier charges as their own line items with the date each was incurred. Attach receipts for anything substantial. Keep disbursements out of the professional fees subtotal. Clients and costs assessors both expect to see them separated, and the tax treatment often differs from the treatment of your fees.

How to make a legal invoice

1. Start from your costs agreement. Before you draft anything, check the rates, billing increment, billing frequency and scope you actually agreed. The invoice has to reflect that document, not what you’d charge today.

2. Pull the time entries for the period. Filter by matter and billing period, then read the descriptions as a client would. Fix vague entries now, while you can still remember what the work was.

3. Apply your write-offs before you send, not after. If an entry took longer than it should have, discount it on the invoice and say so. A visible reduction builds far more goodwill than a client discovering the same charge in a fee dispute.

4. Add disbursements with dates and receipts. Keep them in a separate block from professional fees.

5. Calculate fees, disbursements and tax separately. Subtotal professional fees, subtotal disbursements, apply tax at the correct rate to each, then total. In a spreadsheet template, re-check the formulas cover every row you’ve added.

6. Add the trust block if trust money is involved. Opening balance, amount applied from this invoice, closing balance. Only transfer funds out of trust after the invoice has been issued.

7. State payment terms and the client’s rights. Due date as a calendar date, accepted payment methods, and any notice about costs assessment or dispute rights your jurisdiction requires on a bill.

8. Proofread the numbers and the narrative. Check the matter reference, the period, and that the total matches the line items. Then export to PDF so the figures can’t be altered.

9. Send it to the person who pays. For corporate clients that’s often accounts payable rather than your day-to-day contact, and it may need a purchase order reference.

Once you’re billing more than a handful of matters a month, templates start costing more time than they save. You re-enter client details, retype rates, and rebuild the same trust block each cycle. Bookipi saves clients, rates, and line items so each invoice starts mostly filled in.
