Most law firms don’t lack a process for past-due invoices. They lack the hours to run it every week. Accounts receivable services for law firms fill that gap by taking on the follow-up itself. This guide covers what those services do, what stays with the firm, and what to ask before signing with one.
What are accounts receivable services for law firms?
They are outside teams that follow up on a law firm’s past-due invoices by email, phone and text, in the firm’s name and on wording the firm approves. Unlike a collection agency, they work early in the past-due period with clients the firm still has a relationship with, and they hand open accounts back to the firm rather than taking them over.
Why law firms outsource AR follow-up
Mostly, it’s time. Clio’s 2026 benchmarks put lawyer utilization at 42 percent, or about 3.4 billable hours in an eight-hour day (Clio). Clio’s 2023 Legal Trends Report cites earlier research finding that 48 percent of a lawyer’s non-billable time goes to administrative tasks such as office administration, generating and sending bills, and collections (Clio, 2023).
The other reason is consistency. Reminders tend to go out when someone has a spare afternoon, and calls get skipped because nobody wants to make them. The ABA’s GPSolo division puts it plainly: if a lawyer dreads talking money with clients or is very busy, it is “better to have a professional take this for you” (ABA, 2022).
What an AR service handles, and what stays with the firm
An AR service runs the routine contact. The firm keeps every decision about the fee, the client and the money.
| Task | AR service | The firm |
|---|---|---|
| Reminder emails | Sends them on approved templates | Approves the wording |
| Calls and texts | AR specialists make them | Decides who is never contacted |
| Payment plans | Offers pre-approved terms | Sets the terms |
| Disputes | Pauses and flags them | Resolves them with the client |
| Payments | Points clients to the firm’s link | Receives the money |
| Accounts still open at the end | Returns them with a log | Decides the next step |
| Legal advice or lawsuits | None | The firm or outside counsel |
AR services vs. collection agencies vs. billing software
An AR service does human follow-up early, a collection agency typically works accounts the firm has decided to refer out, and billing software sends automated reminders without a person behind them.
- Billing software reminders. Worth turning on. Clio’s 2023 report found that firms using automated bill reminders collected 49 percent more monthly revenue per lawyer than firms that didn’t. Nobody calls, though, and nobody asks what is in the way.
- AR follow-up services. People, working in the firm’s name, from the day after the due date through roughly the first three months.
- Collection agencies. A later step with its own ethics questions. See whether a lawyer can send a client to collections.
The firm stays responsible for the work
Using an outside team doesn’t move the firm’s ethical duties. ABA Model Rule 5.3 comment 3 says a lawyer using nonlawyer services outside the firm must make reasonable efforts to ensure they are compatible with the lawyer’s professional obligations, considering factors such as the terms of any arrangement to protect client information (ABA). In practice, that means approving the wording, limiting what the provider can see, and being able to stop outreach to any client.
Questions to ask an AR provider

Template: Questions for an AR follow-up provider
1. Who contacts our clients, and in whose name? 2. Do we approve every template and call script before anything goes out? 3. Can we lock specific clients or matters so they are never contacted? 4. How do you connect to our billing system? Is the access read-only? 5. What client information do you see, and how is it protected? 6. Do client payments come to us directly, or through you? 7. How are disputes handled, and how quickly do we hear about them? 8. What reporting do we get, and how often? 9. What happens to accounts still open at the end of your follow-up period? 10. How is your fee calculated: flat, per account, or a percentage of what is collected? 11. What is the contract term, and how does cancellation work?
What outsourced AR follow-up costs
Pricing models vary. Some providers charge a flat monthly fee, some charge per account, and others take a percentage of what is collected. ARCounsel publishes flat pricing: $519 to $1,199 a month by number of clients billed, on an annual plan billed monthly, plus a one-time $625 setup fee, and never a percentage (ARCounsel pricing). For published prices side by side, see our comparison of AR follow-up services for law firms.

Frequently asked questions
Is outsourcing AR the same as using a collection agency?
No. An AR follow-up service works early, in the firm’s name, with clients the firm still serves, and returns open accounts to the firm. A collection agency is usually a later step for accounts the firm has decided to refer out, and it raises separate ethics questions.
Will clients know the firm uses an outside AR team?
It depends on the setup. ARCounsel’s reminders go out in the firm’s name on templates the firm approves. Ask any provider how it identifies itself on calls and in writing before you sign.
How much access does an AR service need?
Enough to see open invoices and contact details. A read-only connection or an aging report export is usually enough, and the provider should not be able to change the firm’s books.
A note on ethics rules. Rules on fee collection vary by state, including when a firm may charge interest on a late bill or refer an account to a collection agency. Check your state’s rules of professional conduct and ethics opinions, or ask your ethics counsel, before setting a collection policy. This article is general information, not legal advice.
