Billing automation for law firms: time captured, invoices out, collections that don't need a partner
Hours get reconstructed on Friday, invoices go out at month end, and the follow-up call is the one nobody wants to make. We build the layer on top of Clio, MyCase, PracticePanther or whatever you run: time captured from the work with a lawyer's approval, the invoice out when the work closes, reminders on a schedule, and one collections view across your billing system and QuickBooks. Trust accounting stays in your system.
What changes for the firm administrator
3 things that decide this
- 01Time entries proposed from the work that already happened, in the lawyer's calendar, inbox and documents, and approved with a tap rather than reconstructed from memory on Friday.
- 02Invoices that go out when a matter stage closes, not when the month does, with the payment link in the email and the reminder sequence already decided by client and matter type.
- 03One collections view across your practice management system and QuickBooks: who owes what, how old it is, what's been promised, and which matters are quietly unprofitable.
From the work to the paid invoice, and what each step writes back
This is the billing station of the full law-firm workflow, opened out into its three steps. Pick your platform to see the write-back.
Station 01 · Capture the time
- Today
- Lawyers reconstruct the week on Friday from memory and the sent folder, and the entries they forget are the ones that never get billed.
- What we automate
- Draft time entries proposed from the calendar, the email thread, the document history and the phone log, tagged to the matter, with the narrative drafted in the firm's style. Nothing posts until the lawyer approves it.
- What stays human
- Approval is the lawyer's, line by line. They edit the narrative, merge, split or delete; the system only proposes.
Writes to ClioApproved time entries posted to the matter with activity code and narrative.
Station 02 · Invoice on close
- Today
- Billing runs once a month, pre-bills sit on desks for two weeks, and the client gets an invoice for work they've half forgotten.
- What we automate
- A matter stage closes and the invoice is generated from approved time and costs, checked against the engagement terms, and sent with the payment link once the responsible lawyer releases it. Flat-fee and contingency matters follow their own rules.
- What stays human
- Your responsible lawyer releases every invoice. Write-downs, courtesy discounts and anything unusual stay a human call, and the system records who made it.
Writes to ClioInvoice created and sent from the matter; payment status synced.
Station 03 · Collect without chasing
- Today
- Reminders go out when someone remembers, the partner makes the awkward call, and the oldest balances are the ones nobody looks at.
- What we automate
- Reminders on a schedule you set by client type and balance age, payment plans offered where your policy allows, and a collections view across your billing system and QuickBooks: aged receivables by matter and client, promised dates, and who to call today.
- What stays human
- Escalation to a person at the threshold you choose, and the client relationship stays the partner's. Trust accounting is never touched; we read balances, we don't move money.
Writes to ClioPayment status and communication log on the matter; trust read-only.
Before this come the inquiry, the engagement and the work itself. The legal hub walks the whole chain.
Four things your billing system won't do on its own
Time from the work, not from memory
Your platform can run a timer. It can't see the email you answered in Outlook, the document you edited in the DMS or the call you took on your mobile. We connect those sources and propose entries the lawyer approves, which is where the unbilled hours have been hiding.
Invoices triggered by the matter, not the calendar
Month-end billing means the client pays for March in May. We tie the invoice to the matter stage and the engagement terms, so work that closes gets billed when it closes, with the responsible lawyer's release as the gate.
A reminder sequence that doesn't need a partner
Payment link in the email, a schedule by client type and balance age, a payment plan where your policy allows it, and escalation to a person at the threshold you set. That awkward call becomes the rare one.
Collections and profitability in one view
Aged receivables by matter and client, realization by lawyer, and matter profitability by practice area, pulled from your practice management system and QuickBooks together. Read-only, custom-built where no report exists, and honest about which matters lose money.
Clio, MyCase, PracticePanther, TimeSolv and the rest all bill. Here's where the layer on top starts.
Every practice management system bills, most take payments through something like LawPay, and most will send a reminder. For a firm whose time is entered promptly and whose clients pay on the first invoice, that's enough, and we'll say so on the audit call.
You outgrow them at three points. Unbilled time happened outside the platform, in email, documents and calls it can't see. Your invoice timing follows the matter, not the month, with rules per engagement type. And the collections picture you need spans the billing system and QuickBooks, by client and by matter, with the profitability question answered alongside it. That's where we build, and trust accounting stays exactly where it is.
- 01Time proposed from the work, approved by the lawyer, posted to your system.
- 02Invoice and reminder rules per engagement type, written down and editable by your billing manager.
- 03Trust accounting read-only, always, and every automated touch logged.
Where your clients' information travels is a design decision we make first, on paper, with you
In United States v. Heppner (S.D.N.Y., February 2026) a court held that material a litigant ran through a consumer AI tool wasn't privileged, because that tool's published terms allowed disclosure and training on inputs. Whether an enterprise tool with no-training terms comes out differently was left open, and we don't treat left open as safe.
So every system we build for a firm starts with a one-page map of where client data goes: which vendor, which region, what's logged, what's retained, and whether a private deployment is required by your clients' own obligations. ABA Opinion 512 makes vetting that part of your duty; we'd rather you vet it before the pilot than after.
- 01Access scoped to the matter, never firm-wide.
- 02Written no-training terms you can produce on request, and every vendor in the chain named as a recipient.
- 03Billing narratives and matter names are client information too: scoped access, no training, and retention on your terms.

Some of the systems we have shipped
- AuditFree. We read last quarter's billed against collected, by lawyer and by matter type, and look at how time gets entered today.
- DiagnoseWe map the path into your practice management system and sit with your front desk and billing for an afternoon.
- BuildFixed price from the diagnostic. Tested on your real matters and real templates, under NDA.
- RunMonitoring, a named engineer, and the first two months of maintenance free.
Best fit: five or more lawyers, a practice management system you've outgrown in places, and someone who owns intake or billing. Not a fit yet: a solo who needs the phone picked up, and we'll say so. You can stop after any stage; the audit note is yours either way.
Before you book
01Will this touch our trust account?+
No. Trust accounting stays in your practice management system and your bank, and anything we build only reads balances to show them alongside receivables. We never move money, never post to trust, and the integration is scoped so it can't. That's a design rule, not a setting.
02Can AI write our time narratives?+
It can draft them, in your firm's style, from the calendar entry, the email thread or the document history. A lawyer reads, edits and approves every line before it posts. Nothing is billed that a lawyer hasn't looked at, which is also what your clients' billing guidelines expect.
03Our billing lives in Clio but our accounts are in QuickBooks. Can you report across both?+
Yes, and that's the most common build. We pull the matter, time and invoice data from your practice management system and the payments and costs from QuickBooks, and build the view neither has on its own: aged receivables, realization by lawyer, matter profitability by practice area. Read-only on both sides.
04What about flat-fee, contingency and retainer matters?+
Each follows its own rule. Flat fees invoice at the milestones in the engagement letter, contingency matters track costs and settlement events, and evergreen retainers top up when they fall below the threshold you set. Those rules are written down per engagement type, and your billing manager can change them.
05Will clients mind automated reminders?+
They mind late, surprising invoices more. A reminder with the invoice attached and a payment link, sent on a predictable schedule in the firm's voice, is what most clients get from every other professional they use. Escalation to a person happens at the threshold you choose, and the relationship stays the partner's.
06What does the free audit look at?+
Last quarter's billed against collected by lawyer and matter type, how time gets entered today and how much of it is reconstructed, how long invoices sit between work and send, and your oldest balances. You get a one-page note on where the gap is and what would close it. Build pricing is fixed after the diagnostic.
A senior engineer, not a sales rep
Abdul Basit founded Hashlogics in 2017, and the team runs from Lahore with a US LLC. Clients rate the work 5.0 on Clutch, and in 2026 it was named Best AI-Native Software House of the Year at TechNova. Lexpair, an AI legal lead-generation platform, is one of the systems we built and can show you.
Your audit call is with an engineer who has read intake logs, matter lists and billing exports like yours. Bring last month's numbers if you have them, and we'll work from those.
- NDA before the first conversation.
- No pitch on the call. A note you could hand to another firm.
- Fixed price after the diagnostic, so the number isn't a guess.
