The gap between doing the work and receiving the cash.
Accounts receivable is the money owed to your firm by clients for work that has been invoiced but not yet paid. For professional services firms, it is not just admin — it is a direct driver of cash flow, partner confidence and client experience.
Different firms. Similar cash flow pressure.
Whether you are billing tax work, legal matters, advisory projects or ongoing services, slow payment usually comes back to the same themes: unclear expectations, inconsistent follow-up and limited payment pathways.
Accounting Firms
Annual fees, tax work, recurring clients, partner relationships and WIP-to-invoice delays.
Legal Firms
Matter billing, client communication, trust balances, disputes and payment expectations.
Professional Services
Project billing, client relationships, scope changes, approvals and cash flow visibility.

Common reasons clients delay payment
The more consistently firms track payment delay reasons, the easier it becomes to improve the process instead of chasing the same debts again and again.
Better AR is usually a process problem, not a people problem.
Strong accounts receivable is not about being harsher with clients. It is about setting expectations early, making payment easier and following up consistently.
