How to Recover Aged Receivables: A Step-by-Step Collections Playbook for Law Firms in 2026
Every law firm has them — invoices that crossed the 90-day line and quietly turned into bad debt. This is the operational playbook for working aged AR back to zero without burning client relationships, using a four-bucket workflow inside LawAccounting.

💸 Why Aged AR Is the Most Expensive Number in Your Firm
Aged accounts receivable is the silent budget killer in most law firms. Unlike a missed billable hour, which announces itself the moment it happens, aged AR accumulates quietly. By the time anyone notices, you have six figures parked at 120+ days, partners are arguing about whether to write it off, and nobody can remember what was actually agreed with the client.
📅 Step 1: Build the Four-Bucket Aging View
Before you can collect, you have to see. Inside LawAccounting, run the AR Aging report with these four buckets:
0–30 Days
Current. Low effort, high cure rate. Friendly reminders and a working portal solve most of this.
31–60 Days
Slipping. Needs a personal touch — billing attorney email, not a system-generated dunning notice.
61–90 Days
Trouble. Schedule a call with the client. Surface any billing disputes before the relationship deteriorates.
90+ Days
Critical. Negotiate, settle, write off, or send to collections. Each invoice gets an explicit decision and an owner.
📨 Step 2: Match the Action to the Bucket
The most common mistake is using the same dunning sequence on every aged invoice. A 28-day-old invoice from a long-term corporate client and a 187-day-old invoice from a former contingency client are completely different problems. Use the right tool for each:
🟢 0–30 Days: Automated, Friendly, Frictionless
Use LawAccounting's client payment portal to make payment a one-click action. Send the invoice the day work is approved, not at month-end. Set a polite 14-day reminder. Most of your 0–30 collections should never need a human touch.
🟡 31–60 Days: Billing Attorney Outreach
A short email from the responsible attorney — not the AR team — outperforms any dunning template. The message: "I noticed the May invoice is still open. Is everything okay on your end? Happy to walk through the detail." It converts because it carries the relationship, not the threat.
🟠 61–90 Days: Pick Up the Phone
Anything past 60 days is no longer a billing problem; it's a relationship signal. Schedule a 15-minute call. Eight times out of ten, the client has a question about a line item, a budget cap, or an internal approval bottleneck — solvable in one conversation, but only if you have it.
🔴 90+ Days: Decide and Document
This is where firms freeze. Don't. Each 90+ invoice gets one of four outcomes documented in LawAccounting:
- Negotiated payment plan with a written schedule
- Partial write-down in exchange for immediate payment
- Full write-off with a journal entry to bad debt expense
- Referral to collections only when the relationship is already dead
🛠️ Step 3: Make the Process Weekly, Not Quarterly
The single biggest predictor of collections health is frequency, not effort. Firms that review AR weekly collect 30–40% more than firms that review monthly, because problems are caught while the work is still fresh in everyone's memory. Block 30 minutes on Friday mornings. Stand the meeting up between the billing attorney for each matter and the AR lead. Walk the report top to bottom.
🤖 Step 4: Use LawAccounting's Built-In Levers
The collections workflow gets much faster when the accounting system actually helps. Inside LawAccounting:

🎯 What "Good" Looks Like
For a healthy mid-market law firm in 2026, an aging profile should look roughly like this:
| Bucket | Healthy Firm | At-Risk Firm |
|---|---|---|
| 0–30 Days | 60–70% of total AR | < 40% of total AR |
| 31–60 Days | 15–20% | 20–30% |
| 61–90 Days | 5–10% | 15–20% |
| 90+ Days | < 10% | > 25% |
If more than a quarter of your AR is over 90 days, the firm is effectively financing its clients — and at modern interest rates, that's an expensive habit.
- Aged AR is the most expensive line item most firms refuse to look at. The cure is visibility plus weekly cadence, not bigger dunning emails.
- Use four buckets — 0–30, 31–60, 61–90, and 90+ — and match a different action to each. Same-template-for-everyone is what created the backlog.
- By day 61, the problem is no longer billing — it's relationship. Pick up the phone.
- Every 90+ invoice must get an explicit decision: collect, negotiate, write down, or write off. Stalling is the most expensive option.
- LawAccounting's aging reports, payment portal, trust application, and realization tracking are built for exactly this workflow — use them.
