Everything Included In Legal Billing Software

We engineer the full legal billing operating layer: configurable workflow logic, user experiences, integrations, data controls, quality assurance, cloud delivery, and the support needed to evolve the platform as billing rules, matters, and client expectations change.

Time & Expense Capture

We create web and mobile experiences for contemporaneous time entry, expense receipts, narratives, timers, and matter-aware activity codes.

LEDES & UTBMS Validation

We validate invoice files, task codes, activity codes, expense codes, rates, and required fields before submission to reduce rejection loops.

Rules-Based Invoice Review

We automate billing guideline checks for rate caps, staffing rules, block billing, duplicate entries, budgets, and matter-specific exceptions.

E-Billing Workflows

We build configurable submission, review, appeal, adjustment, approval, and status-tracking workflows for firms, clients, and legal operations teams.

Matter, Rate & Budget Management

We centralize matter profiles, timekeeper rates, alternative fee arrangements, budgets, accruals, and client-specific billing requirements.

Collections & Payment Operations

We support invoice delivery, payment links, remittance matching, aging workflows, and finance-system synchronization while respecting trust-account controls.

Spend Analytics & Reporting

We deliver dashboards for realization, write-offs, aging, matter spend, outside-counsel performance, rate compliance, and billing-cycle health.

AI-Assisted Billing Intelligence

We apply governed AI to classify narratives, flag guideline risks, summarize invoice exceptions, and help reviewers prioritize high-value work.

Security & Compliance Built Into Every Solution

Trust is essential in legal technology. We integrate security, privacy, and compliance throughout the software development lifecycle to protect privileged legal information and sensitive client data.
