Trusted by law firms and solo practitioners
Built for legal professionals
Billing features designed for the unique needs of legal practices — from solo practitioners to small firms
Time-Based Billing
Track billable hours per client and matter. Generate itemized invoices showing time entries, rates, and descriptions. Support for multiple billing rates on a single invoice for different team members.
Retainer Management
Bill against retainers, track balances, and send automatic replenishment invoices. Clients see clear retainer statements showing drawdowns and remaining balances on every invoice.
Detailed Invoices
Itemized billing statements that meet corporate and institutional client requirements. Each line item includes matter references, task descriptions, and time entries — the detail level procurement teams expect.
Compliance & Security
Secure record-keeping with immutable audit trails. Tax-compliant invoicing with cryptographic verification. Every document is verifiable via QR code — trusted by auditors and regulators.
How lawyers use Invoicemonk
Whether you're a solo practitioner or managing a small firm — here's how Invoicemonk fits your legal billing workflow
Litigation & Disputes
Log billable hours as you work on a case — research, drafting, court appearances, client consultations. At the end of the billing cycle, generate an itemized invoice showing every time entry with dates and descriptions. Corporate clients get the transparency they require.
Retainer-Based Advisory
Set up retainer agreements with monthly billing. Invoicemonk tracks the retainer balance, deducts each invoice from the pool, and automatically sends replenishment invoices when the balance runs low. Clients always know where their retainer stands.
Transaction & Conveyancing
Bill for property transactions, company formations, or contract drafting with milestone-based invoicing. Collect an initial deposit, bill at key milestones, and send a final invoice on completion. Each document is cryptographically verified for regulatory confidence.
Common legal billing challenges — solved
We built Invoicemonk around the real problems legal professionals face
Losing billable hours because time entries are tracked in notebooks or forgotten entirely
Record time entries per client and matter as you work. When it's time to invoice, all entries are ready — no more lost revenue from forgotten billable time.
Clients disputing invoices because billing statements lack detail or transparency
Itemized invoices show every time entry with dates, descriptions, rates, and durations. Clients see exactly what they're paying for, reducing disputes.
Manually tracking retainer balances across multiple clients in spreadsheets
Retainer drawdown tracking shows remaining balances on each invoice. Automatic replenishment invoices go out when balances run low.
Spending hours preparing financial records for compliance reviews or tax audits
Every invoice, receipt, and payment is automatically logged with immutable audit trails. Export compliance-ready reports in one click.
How it works
From client onboarding to compliance reporting — in four steps
Onboard the client
Add the client's details to Invoicemonk — name, company, billing address, and tax ID. For retainer-based engagements, set up the retainer amount and billing schedule. The client is now ready for invoicing with all details saved.
Log time and expenses
As you work on the client's matters, log billable hours with descriptions. Record case expenses — filing fees, travel, expert consultations. Everything is stored per client and per matter, ready for invoicing.
Generate and send invoices
Create an itemized invoice pulling in all logged time entries and expenses. Review the statement, apply retainer drawdowns if applicable, and send. The client receives a professional email with your firm's branding and a verification QR code.
Track payments and report
Monitor payment status in real time. Automated reminders handle overdue invoices professionally. At quarter or year-end, generate compliance reports and income summaries for your accountant or regulatory filings.
Why lawyers choose Invoicemonk over alternatives
Legal billing has unique requirements that generic invoicing software doesn't address. Lawyers need time-based billing with detailed descriptions, retainer management with balance tracking, and compliance-grade audit trails. Most invoicing tools treat these as afterthoughts — Invoicemonk builds them in from the start.
Every invoice Invoicemonk generates includes a cryptographic verification code and QR code. This means any client, auditor, or regulator can independently verify the authenticity of your billing documents — a level of transparency that builds trust and satisfies compliance requirements without extra work on your part.
For small firms, the team management features let associates and paralegals log time entries while partners retain control over invoicing and client relationships. Role-based access ensures everyone has the right level of visibility without compromising sensitive client information.
