Recover Unpaid Invoices for Professional Services Firms

Your firm runs on billable work. When clients don't pay, your margins and your team's time take the hit. NSB recovers past-due receivables for companies that serve other businesses, such as accounting, consulting, marketing, call centers, and more. You can protect client relationships and stay focused on the work, while we collect for you.

You only pay when we collect. No recovery? No fee.

Why Professional Services Invoices Go Unpaid

We work with firms that support other businesses, including accounting and consulting, legal services, marketing and creative, HR and training, translation, printing, security, and facilities and cleaning services.

Scope and Billing Disputes:

Clients question hours, deliverables, or project scope after the work is done.

Work Delivered Before Payment:

Services are already provided, so there's nothing to take back when a client stops paying.

Clients Who Go Quiet:

Once a project wraps up, slow-paying clients stop returning calls and emails.
