Invoice templates for freelance legal consultants billing law firms, in-house legal teams, and businesses for legal advisory services.
A legal consultant invoice is issued by a qualified solicitor, barrister, or non-practising legal professional providing advisory or support services on a consultancy basis to law firms, in-house legal departments, or businesses. Unlike practising solicitors, legal consultants may work outside a regulated firm and typically hold a non-practising certificate or provide services through a vehicle authorised by the SRA or BSB. Legal consultancy covers a wide range of work: strategic legal advice, contract drafting and review, compliance advisory, due diligence support, litigation strategy, regulatory guidance, and outsourced general counsel services. Rates vary substantially depending on specialism, seniority, and whether the work is for a law firm (where the client is the firm, not the end client) or a direct business engagement. Because legal consultants often work remotely and across multiple clients simultaneously, a clear invoicing process is essential for tracking billable time, maintaining matter files, and demonstrating the value delivered. Some consultants invoice under their own name; others trade through a limited company, which affects how VAT and tax obligations are structured.
| Service | Typical Rate | Unit |
|---|---|---|
| Legal advisory (hourly) | 200 | hour |
| Contract drafting and review | 200 | hour |
| Due diligence support | 180 | hour |
| Compliance review (fixed fee) | 1500 | project |
| Monthly retainer | 2500 | month |
| Court or regulatory filing fee | 50 | disbursement |
Legal consultants billing hourly should invoice monthly or on completion of a defined phase of work. Provide a narrative of work done against each matter or project, with dates and time recorded in the standard 6-minute billing unit used across the legal profession. For retainer arrangements, issue the retainer invoice at the beginning of each month with payment due in advance. Any work exceeding the agreed retainer hours should be invoiced separately at the agreed overage rate at month end. Fixed-fee engagements should be invoiced in stages: typically 30-50% on commencement and the balance on completion or milestone achievement. Include the scope of the fixed fee clearly on the invoice so any out-of-scope additions can be billed separately. If you operate through a limited company, ensure invoices are issued in the company name and that your company's registered number appears on the invoice. This is a legal requirement for UK limited companies. VAT-registered companies must include their VAT registration number and charge 20% on all professional fees.
