CollBox

CollBox is an Austin-based back office outsourcing service built specifically for law firms that need to recover past-due invoices without putting client relationships at risk. Rather than leaving aged receivables to sit or turning them over to traditional debt collectors, CollBox assigns a dedicated accounts receivable specialist to handle all follow-up calls and emails professionally, keeping the firm's name and reputation intact throughout the process. The service is available as a one-time clean-up engagement, ongoing monthly support, or a combination of both. After signing on, firms meet their dedicated specialist, complete a brief onboarding session to share preferences and instructions, and go live within one to two weeks. From that point, the specialist manages all outbound contact with clients who have overdue balances. Every call, email, and update is logged directly in the CollBox platform, giving the firm complete visibility through a central dashboard. Firms retain 100% of payments collected, with no contingency fee model and no need to switch away from existing tools. The target client is a law firm that bills hourly or in installments and finds itself spending staff time chasing invoices rather than serving clients. This is back office work that most firms handle reluctantly and inconsistently. CollBox's North America-based team handles it as their core function, applying a consistent, persistent approach that stays professional at every stage. The company has recovered more than $100 million for firms of varying sizes and reports that clients see their average time to get paid improve by 40%. On the integration side, CollBox connects directly with Clio, Smokeball, QuickBooks, and other practice management and accounting systems. There's no need to manually export data or maintain a separate workflow. For firms whose books need work before they're ready to start, CollBox can assist with clean-up and can refer more complex cases to vetted specialists in their network. For any law firm considering outsourcing its receivables function, CollBox offers a practical, low-friction way to get started. The team handles the calls, tracks the progress, and keeps the firm informed while attorneys and staff focus on their actual work. Firms interested in clearing a backlog of past-due accounts or setting up ongoing AR support can reach the team directly through the CollBox website.
