Accounts receivable software for law firms that automates law firm accounts receivable management and legal collections

Law firms have a collections problem that has nothing to do with the quality of the work. The bill goes out at the end of the month, the client sits on it, and nobody follows up, because the person best placed to chase it is the partner who has to keep working with that client tomorrow. So the invoice ages. Clio's 2025 Legal Trends Report puts the median collection lockup at 32 days, meaning a month of billed revenue is sitting unpaid at any given moment, and the average collection rate at 93 percent, so roughly seven cents of every billed dollar is never collected at all. On a firm billing $4 million a year that is about $280,000 in earned fees written off, plus the working capital tied up in everything still outstanding.

AccountsReceivable.ai is accounts receivable software built to work that ledger for you. It connects to the accounting system your firm already runs, QuickBooks or Xero, reads every open matter invoice, and chases each one on a schedule a busy billing coordinator cannot keep by hand. It escalates from a polite reminder email to SMS to a live AI phone call as the invoice ages, flags the partial payments and line-item disputes that hourly billing produces, applies incoming client payments to the right invoice, and predicts when each client will actually pay. The follow-up stops being a favor someone does when they have time, and no partner has to open a call by asking about an outstanding bill. Flat monthly fee, and it never takes a percentage of what it collects.

Why it works

What your team gets with AR for law firms

Takes the awkward call off the partner

The single biggest reason legal invoices age is that chasing them falls to the attorney who owns the client relationship, and that call keeps getting postponed. The agent runs the entire follow-up sequence on its own, from the first reminder through a live AI phone call, so the money conversation happens on schedule and separately from the partner who still has to argue the case next week.

Works line-item disputes on hourly bills

Hourly billing invites clients to pay most of an invoice and question a handful of time entries. Those partial payments quietly become write-downs. The agent catches the short-pay at cash application, keeps the disputed balance open and chased, and routes it for review, so a challenged entry gets resolved on purpose instead of disappearing into the realization gap.

Cuts collection lockup, not just the aging report

Collection lockup is the stretch between sending the bill and banking the money, and it is the half of law firm lockup that follow-up actually moves. By chasing every invoice from the day it goes past due rather than the day someone notices, the agent pulls cash forward across the whole ledger and gives you a predicted pay date per client to plan draws and payroll against.

What it handles

Chased, collected and reconciled on autopilot

The agent syncs your invoices, chases each one across email, SMS and phone, applies incoming payments to the right invoice, reconciles your ledger, and predicts when every customer will pay.

Why AccountsReceivable.ai

One agent that runs the whole receivables job

Not a reminder tool, not a six-figure suite, and not an agency that takes a cut. Chase, collect, apply cash and forecast in one place, on top of the accounting system you already use.

Chases every invoice

The full dunning sequence runs on autopilot across email, SMS and live AI phone calls, polite and on-brand, so no overdue invoice slips through.

Applies the cash

Incoming wires and ACH batches are matched to the right invoices automatically, so your ledger reconciles and you never chase an invoice that already paid.

Cuts your DSO

A predicted pay date for every open invoice and steady follow-up bring DSO down week over week, so more cash lands when you need it.

Good questions

Questions about AR for law firms

Last updated July 2026

Because collecting falls to the attorney who owns the client relationship, and chasing money strains that relationship, so the follow-up gets postponed. Hourly bills also invite clients to dispute individual time entries and pay the rest. Clio reports a median collection lockup of 32 days and an average collection rate of 93 percent, so most firms carry a month of unpaid billed work and write off part of it.

Collection lockup is the number of days of annual revenue tied up in invoices that have been sent but not paid. It is one half of total lockup, the other being realization lockup, which measures work done but not yet billed. Clio puts the 2025 median collection lockup at 32 days. Consistent follow-up on every open invoice is the lever that moves it, because most of the delay is invoices nobody chased.

No. It does not generate bills, track time, or touch trust and IOLTA accounts, and it is not a practice management system. It sits on top of the accounting ledger your firm already keeps in QuickBooks or Xero, works from the invoices you already issue, and handles what happens after the bill goes out: chasing it, applying the payment, and reconciling.

The sequence starts soft and stays professional, and it comes from the firm rather than from the partner personally, which is what makes it repeatable. A reminder goes out when the invoice hits its due date, follow-ups escalate on a set schedule, and only aged invoices reach a phone call. You set which clients are handled with extra care, and anything disputed routes to a person before it escalates further.

The agent catches it at cash application. When a client pays most of an invoice and withholds an amount, that short-pay is flagged rather than absorbed, the disputed balance stays open and tracked, and it is routed for a human decision. The write-down still happens only if you decide it should, instead of by default because nobody followed up on the difference.

Yes, with a two-way sync to either one. It reads your open client invoices and writes payments and status back, so the books stay reconciled and nothing about how your firm bills has to change. Firms that produce invoices in a practice management system and push them into QuickBooks or Xero simply add the agent on top of that ledger.
