  • We've been blown away by the response we've gotten from the legal community. Recent recognitions by Clio and ABA Tech Show, and ALA have us feeling grateful and also considering what is next for Legal Tech.

  • Incredible stuff here from the Clio team. We've had similar thoughts on the future of legal tech, and it's great to be affirmed in the direction we're on.

    What are #legaltech startups actually building right now? 👀 We recently got back from #ABATECHSHOW 2026’s Startup Alley, and the startups that stood out aren’t asking lawyers to type prompts, they’re building tools that do the work and hand you the output. Clio’s Solution Champion, Damien Riehl, and Lawyer in Residence, Joshua Lenon, break down the biggest trends from this year’s finalists, and what it means for lawyers. 👀 Catch their full discussion at the link in our comments.

  • Our co-founder Matt Darner sat down with Ruby Powers on Power Up Your Practice to talk about what he sees across hundreds of law firm billing situations, and it's almost always the same picture: A growing aging report. Closed matters with unpaid invoices. And attorneys who know the problem exists but keep putting it off. The moment a matter closes is the moment your ability to collect starts shrinking. At 90 days past due, you've already lost 47% of your collectability. At two years, you're working with a 15% success rate. Matt also gets into the "ick factor" — why 99% of attorneys hate chasing clients for money, why the wrong person is almost always doing it, and what you can actually do about it. Plus the upstream fixes: the intake conversations, retainer policies, and billing habits that prevent the problem before it starts. If you've got invoices sitting unpaid and you're not sure what to do about them, this episode is worth your time.

    You did the work. You sent the invoice. And somehow… it's still unpaid📋 That number sitting in your aging report? Matt Darner says it's costing you more every single day you wait to deal with it. In this new episode of Power Up Your Practice, the co-founder of CollBox — and #ABATECHSHOW2026 Startup Alley winner — breaks down why law firms leave thousands uncollected, when it's too late to recover an invoice, and what to fix upstream so you're not chasing clients for money in the first place. Practical, honest, and a little uncomfortable in the best way 🎙️Tune in! https://lnkd.in/ekvkP46g #LawFirmGrowth #CashFlow #PowerUpYourPractice #LawPracticeManagement #GetPaid

    The average small law firm has $300K–$800K in unpaid invoices sitting past 90 days. By that point, they've already lost nearly half their collectability. This week Ruby Powers sits down with Matt Darner, co-founder and CEO of CollBox, to talk about the collections problem no one wants to deal with — and exactly what to do before it's too late. 🎙️ Show Me the Money: Getting Paid & Collecting Before It's Too Late — now live https://lnkd.in/eFw7MnpP

  • Realization lockup: The gap between doing the work and sending the invoice (averaging 38 days, per Clio's Legal Trends Report). Collections lockup: The gap between sending the invoice and actually getting paid (another 45+ days). Add them together and you're waiting 90+ days on money you've already earned. If your monthly overhead is $50K, that's $150K in cash reserves just to cover the gap. Most small firms don't have that cushion. That's how profitable practices end up financially stressed: not because they lack revenue, but because of the time between earning and receiving it. We put together a complete guide to managing law firm A/R: the two types of lockup, why invoices really go unpaid, the 14-day and 90-day rules every firm should follow, and how to know when it's time to bring in outside help. https://lnkd.in/efHJv5fN

    You’ve generated the lead. You’ve done the work. But getting paid still feels inconsistent. For many law firms, the gap isn’t in marketing—it’s in collections. That’s where CollBox comes in. It combines automated outreach with human follow-up to help law firms recover outstanding invoices—while maintaining positive client relationships. And unlike traditional collections models, you keep 𝟭𝟬𝟬% 𝗼𝗳 𝘄𝗵𝗮𝘁’𝘀 𝗰𝗼𝗹𝗹𝗲𝗰𝘁𝗲𝗱. Because revenue doesn’t just come from new clients. It comes from closing the loop on the work you’ve already done. 👉 If your firm is carrying aging receivables, this is worth a closer look: https://lnkd.in/gPkEWH5V 𝘛𝘩𝘪𝘴 𝘱𝘰𝘴𝘵 𝘤𝘰𝘯𝘵𝘢𝘪𝘯𝘴 𝘢𝘯 𝘢𝘧𝘧𝘪𝘭𝘪𝘢𝘵𝘦 𝘭𝘪𝘯𝘬.

  • Looking forward to seeing this one!

    𝗥𝗲𝘁𝗮𝗶𝗻𝗲𝗿𝘀 𝗲𝘅𝗽𝗹𝗮𝗶𝗻𝗲𝗱 𝘀𝗶𝗺𝗽𝗹𝘆: 𝘁𝗵𝗲 "𝗴𝗮𝘀 𝗶𝗻 𝘁𝗵𝗲 𝘁𝗮𝗻𝗸" 𝗮𝗻𝗮𝗹𝗼𝗴𝘆⛽⚖️ Mastering the "money talk" is a critical operational move. If you can’t explain your retainer policy simply, you’re creating friction in your cash flow and losing client trust. In our next episode, Matt Darner and Ruby Powers discuss why clarity is the ultimate fuel for your firm. Stop letting billing confusion slow down your practice. Coming next week to Power Up Your Practice! 🎙️

  • In a recent ALA CLE session, nearly 60% of attendees weren't tracking collections lockup and 75% had no defined A/R policy. That's a lot of cash sitting on the table. This session is built to be practical. Matt will cover how to establish real A/R policies, apply low-resistance client follow-up strategies, and use technology to get paid faster without damaging client relationships. You'll leave with ready-to-use tools, not just ideas. If you're attending ALA this year, come find us. We'd love to connect.

    I'm speaking at ALA's 2026 Annual Conference & Expo in National Harbor, Maryland! My session, "Practical Accounts Receivable Strategies to Unlock Profitability and Reduce Stress," is something I've been looking forward to building for a while. The legal administrators in the room are often the ones holding the financial health of their firms together, and A/R is one of the biggest levers they have. We'll talk about how to measure and reduce collections lockup, how to build a defined A/R policy, and how to follow up with clients in a way that actually works (and doesn't feel awkward). Attendees will also walk away with real tools and guides they can put to use immediately. If you're going to be at ALA this year, let's connect! Drop a comment or find me at the session. Hope to see you there! #ALAConf26 #LegalManagement #AccountsReceivable #LawFirmFinance #CollBox
