How to Run a Legal Billing Software Demo on Your Own Matters

The demo goes well. The presenter’s sample firm has tidy matters, round-number rates, and clients who pay in full on the due date. An invoice builds itself, a payment drops in, the dashboard turns green, and everyone on your side nods. Then, three weeks after you sign, your bookkeeper tries the first month-end close and finds that the write-down on a real matter landed somewhere nobody expected.

A legal billing software demo is the one hour where you control what the vendor has to show you. It’s easy to spend it watching a script. This post is about spending it on your own matters instead: what to bring, what to ask the presenter to do live, which answers should give you pause, and who needs to be watching. If you are still building the list of what to ask about at all, start with the buyer’s checklist for small-firm billing software and come back here to test it.

Why a legal billing software demo on sample data tells you so little

Sample data is built to make the happy path look good. Every matter has one rate, nobody disputes a line item, retainers never run short, and nothing has to be corrected after the invoice goes out. Your firm doesn’t work that way, and the places where it doesn’t are exactly where billing software earns or loses its keep.

The fix is to change the script. Pick a handful of real situations from the last quarter, strip out client names, and send them to the vendor a few days before the call with a short note: “Please run these live in a demo account during our meeting.” A vendor confident in its product will say yes. One that steers you back to the standard tour has told you something too.

Three scenarios to bring from your own books

Choose matters that caused someone at your firm a headache. Each of these tests a different part of the path from work performed to cash in the bank.

A write-down and a partial payment

Take a matter where a partner cut time before the bill went out and the client then paid only part of the invoice. Ask the presenter to enter the time, apply the write-down, send the invoice, and record the partial payment.

Then watch three things. Where does the write-down live after it is applied, and can you report on it later by matter and timekeeper? That record is how you see realization (what the firm billed against the value of the time worked), and a system that buries it leaves you guessing about where money stays on the table. Does the open balance show correctly, and does it age the way your receivables actually age? And what does the client see on the next statement?

A retainer applied to an invoice

Pick a client who paid an advance. Under ABA Model Rule 1.15(c), fees paid in advance go into a client trust account and come out only as they are earned; each state adopts its own version of the rule, so check your jurisdiction’s. Ask the presenter to record the deposit, issue an invoice, apply the trust funds to it, and show you that client’s trust balance before and after.

Then ask yourself whether the person who reconciles your accounts could defend each step to an auditor without rebuilding it by hand.

An invoice that has to reach the books without re-keying

Ask the presenter to send an invoice, take a payment against it, and then open the accounting system live, on screen, with no screenshots. Where did the invoice land? Which customer record, which income account? Does the deposit match what will show up on the bank statement, including any processing fees?

If someone at your firm currently types invoice totals into the accounting system, this is the scenario that tells you whether that work goes away or just moves.

One more for your operating model

Add a fourth scenario for the way you bill when it isn’t hourly. For a flat fee practice, set up a flat fee matter, log time against it anyway, and ask to see what the firm actually earned per hour on it; flat fee work is where margin quietly thins out. For a contingency practice, ask to see expenses advanced on a case and how they roll up at resolution. ABA Model Rule 1.5(c) requires a written agreement stating whether expenses come out before or after the fee is calculated, and a written statement to the client at the conclusion of the matter, so the expense record has to hold up years after the first entry.

What to ask the presenter to click through live

A good presenter can talk through anything. Your job is to keep them clicking. A few requests that do most of the work:

• “Can you do that in this account, right now?”
• “Show me the screen my bookkeeper would use for this, not the partner view.”
• “Now undo it. What happens to an invoice that’s already in the books when we void it?”
• “Run the report a partner would ask for on Monday morning, for this matter.”
• “If the connection to our accounting system fails overnight, how would we know, and who fixes it?”

Keep a scorecard open while they work. For each scenario, mark one of three outcomes: done live in the product, shown on slides or described, or not possible today. Only the first one counts as a yes.

Answers that should worry you

Some answers sound reassuring in the room and read differently a month later.

“That’s on the roadmap.” The feature doesn’t exist. Roadmaps change, and you will be running your firm on what ships today. Ask for the timing in writing if it matters, and score it as absent.

“Our services team handles that.” A person is doing what you assumed the software did. Sometimes that’s fine: a one-time data import is a reasonable thing to hand to a vendor. Ask whether the help is part of setup or something you’ll depend on every month, and what happens when that team is busy at your month-end.

“Most firms don’t do it that way.” Your firm does. If the workflow you’ve been asked to demonstrate is common in your practice area, the vendor should be able to show it.

“You’d handle that in your accounting system.” This one can be perfectly reasonable; reconciliation, for instance, belongs in the accounting system of record. Follow up with one question: does anything have to be typed twice to get it there?

Who should be in the room

Partners usually attend demos. The person who does month-end usually doesn’t, and that absence tends to surface at the first close.

Bring three perspectives. The partner who approves bills will judge the invoice review and the reports. A working timekeeper will tell you, honestly, whether they’ll enter time in it. And the bookkeeper or firm administrator who closes the books will notice the thing nobody else does: the payment that posted to the wrong account, the trust transfer with no matching entry, the report that doesn’t tie to the ledger. If you can bring only one non-partner, bring that person.

For more questions to put in front of a vendor, these eight questions to ask before you commit to timekeeping and billing software and the questions to work through when considering a switch are good companions to your scorecard.

What the partners should take away from the demo

Run this way, a demo answers the questions a managing partner actually cares about. The write-down scenario shows whether you’ll be able to see what the firm worked versus what it billed. The partial payment and retainer scenarios show how quickly money moves from invoice to bank, and whether anyone has to chase it by hand. The re-keying scenario shows how many hours of month-end work the firm will keep paying for.

If LeanLaw is on your list, hold it to the same test. It’s built on QuickBooks Online, which it requires, so invoices, payments, and trust transfers should land in QuickBooks Online without re-entry while you watch, and it runs hourly, flat fee, and contingency matters in one platform, so bring your messiest example of each. However you’re comparing vendors for the best legal billing software for small firms, the vendor that runs your matters live, on screen, with your month-end person watching, is the one that has earned the next conversation.
