Bill4Time is legal time-tracking and billing software that combines case management, invoicing, and online payments for professional services firms. Designed for law firms, accountants, consultants, and architects, Bill4Time combines real-time desktop and mobile time entry, customizable branded invoicing with batch generation, and native online payment processing that supports trust accounting compliance. The platform also includes interactive dashboards for collections, aging invoices, and trust balances, plus a secure client portal and QuickBooks integration. Bill4Time is a strong fit for solo attorneys and small firms that bill hourly and need an integrated practice management workflow rather than separate time, billing, and payments tools.
