Law firm billing software
Bill the time you actually worked.
Time captured as the work happens rather than reconstructed on a Friday afternoon, invoices in any currency, retainers and trust reconciled in real time, and profitability visible per matter, per partner, and per client.
Capabilities
From the work to the payment.
Billing software fails at the two ends: capturing the time honestly, and collecting the money promptly. The middle, producing an invoice, is the part everyone already does.
Automatic time capture
Research, drafting, and calls timed against the matter as they happen, editable before the invoice goes out.
Multi-currency invoicing
Bill local clients in local currency and international clients in theirs, with jurisdiction-aware tax, from one matter list.
Retainers and trust
Client money held separately from operating funds and reconciled in real time, with an exportable audit trail.
Live profitability
Revenue, work in progress, collections, and write-offs by matter, partner, practice area, and client.
In depth
Where the money leaks.
Capture
Reconstructed time is always lower than real time.
A fee earner writing up their week on Friday does not remember Tuesday’s twenty-minute call or the half hour spent checking an authority. That shortfall never appears in any report, because a firm cannot report on time it never recorded. Because ModulawAI is where the research, drafting, calls, and client messages happen, the time is a by-product of the work rather than an act of memory.
Collection
An invoice nobody chases is a donation.
Ageing invoices are visible on the dashboard rather than discovered at the quarter end, clients can see and settle invoices in the portal without an email exchange, and the follow-up is a tracked task with an owner. See the client portal.
Pricing
Hourly, fixed fee, and contingency together.
Firms rarely bill one way any more. Hourly, fixed-fee, capped, and contingency matters sit side by side on the same list, each with disbursements charged correctly, so profitability comparisons across pricing models are possible rather than theoretical.
FAQ
Questions, addressed.
What is law firm billing software?
Law firm billing software records billable time against matters, produces client invoices, tracks payments and disbursements, and handles client or trust money separately from the firm’s operating funds. The difference between products is usually how honestly time gets captured and how well the money gets collected, rather than the invoice itself.
Does it handle trust and client accounts?
Yes. Retainers and client money are held and reported separately from operating funds and reconciled in real time, with every movement date-stamped, attributable, and exportable for audit or compliance review.
Can we bill in more than one currency?
Yes. Invoicing is multi-currency with jurisdiction-aware tax, so a firm can bill local clients in local currency and international clients in theirs from the same matter list.
Does it replace our accounting package?
It handles billing, disbursements, retainers, and trust reconciliation and exports to standard accounting formats. Most firms keep their statutory accounting package and use ModulawAI as the operational source of truth.
How is time actually captured?
Timers attach to the activity itself, so research, drafting, and calls performed inside the platform are timed against the matter automatically. Entries stay editable until the invoice is issued.
The number partners actually watch
Realisation is where the money goes.
Billing software is usually sold on invoice design. The money is lost earlier, in the gap between the time a firm works, the time it records, the time it bills and the time it collects. Each gap has its own name and its own fix.
| Stage | What leaks | What closes it |
|---|---|---|
| Worked to recorded | Time nobody wrote down. Short calls, a colleague’s question, the twenty minutes before a hearing. Reconstructed on a Friday, this is guesswork that always rounds down. | Capture at the moment of work. Research, drafting and calls timed against the matter as they happen, editable before anything is billed. |
| Recorded to billed | Entries a partner strikes at review because the narrative does not justify them. A line that says ‘review documents’ invites a write-off. | Narratives written from what actually happened, with the matter and the document in view, so the entry defends itself. |
| Billed to collected | Invoices that age quietly. Lock-up is work in progress plus debtor days, and it is the number that decides whether a profitable firm can pay salaries. | Ageing visible per client and per partner, with the collection chase attached to the matter rather than to somebody’s memory. |
Realisation rate is recorded time turned into billed value; collection rate is billed value turned into cash. A firm can look busy and profitable on both a timesheet and a profit and loss account while lock-up quietly consumes everything it earns. Those two ratios, per matter and per partner, are the report to look at first.
Currency, tax and the cross-border bill
Billing across borders is not a formatting problem.
A firm billing a Lagos client in naira and a London client in sterling is running two different compliance positions from one matter list, and the invoice is the least of it.
- The currency is a decision, not a display setting. Which currency a matter bills in, and the rate applied at invoice date, both need recording, because the difference shows up again at collection.
- Tax treatment follows the client, not the firm. Indirect tax and any withholding on professional fees differ by jurisdiction and by the client’s status, so the rule belongs on the matter.
- Withholding is common on African engagements. Where a client deducts at source, the invoice and the receipt will not match, and the difference has to be reconciled rather than written off as a shortfall.
- Client money stays separate throughout. Retainers and trust balances are reconciled continuously and exported for audit, whatever currency they are held in.
What this does not do. It is not an accounting system and it does not file a tax return. Your accountant still owns the ledger and the returns. What it owns is the record of what was worked, on what matter, in what currency, on whose authority, so the numbers your accountant receives are complete.
