Law Firm Engagement Letter + Retainer Billing Tracker

Create a clearer law-firm intake and billing workflow with an editable engagement letter, matter-level retainer tracker, invoice register, and optional fillable PDF.

The **Law Firm Engagement Letter + Retainer Billing Tracker** is an editable Word + Excel bundle for solo attorneys, boutique firms, legal operations teams, and billing coordinators who need scope, rates, time, expenses, invoices, and retainer activity in one controlled workflow.

What’s inside

• Editable Word engagement letter with parties, matter identity, scope, exclusions, client responsibilities, communication, confidentiality, conflicts, fee basis, rates, expenses, billing timing, retainer treatment, changes in scope, termination, governing-jurisdiction prompt, and signatures.
• Editable Excel tracker with Matter & Rates, Time Entries, Expenses, Invoice Register, Retainer Ledger, Dashboard, Client Statement, and Checks tabs.
• Linked rate and fee calculations for partner, associate, and paralegal timekeepers.
• Invoice totals, payments, balance due, days outstanding, and accounts-receivable view.
• Matter-level retainer / client-funds ledger separating deposits, earned-fee transfers, expense transfers, refunds, running balance, and review flags.
• Current-matter Dashboard with fees earned, billable expenses, invoices, A/R, retainer balance, hours, and realization.
• Optional interactive fillable PDF engagement form.
• Four Sharpline gallery mockups, README, and QA notes.

Built for

Solo attorneys, boutique law firms, litigation practices, business-law firms, estate-planning practices, legal operations coordinators, billing managers, and fractional law-firm administrators.

Why this is different

The workflow keeps the handoff visible: **scope + rates → time + expenses → invoice → payments / earned transfers → client balance**. It also separates operational billing calculations from the legal and accounting review that each firm must complete locally.

Format

Editable Microsoft Word (`.docx`), editable Microsoft Excel (`.xlsx`), and optional interactive fillable PDF (`.pdf`).

Important note

This is a working draft and operational template, not formal legal advice, trust-account software, accounting advice, or a universal engagement agreement. Review it with qualified local counsel and the firm’s accounting / trust-account professional before use.
