Good Morning Thorium Valley, welcome back to the Catalyst Newsletter.
Today we're talking about 30 tax professionals who had zero coding experience, got handed AI tools for six weeks, and walked out with working software their firm actually uses with real clients.
We're also looking at a CPA who let an AI agent do his bookkeeping on camera, it processed 6,700 transactions in under eight minutes, and 150,000 accountants watched because they all wanted to know how.
And we're checking out a cowboy boot company that split its inventory in half, let AI manage one side and humans manage the other, and the AI side outsold the humans by nearly 10%.
Quickly before we dive in — When AI gives you a result, how much do you trust it before double-checking?
OPERATIONS
KPMG handed 30 of its tax professionals access to AI coding tools and gave them six weeks. By the end, they had built automation tools that the firm now uses with actual clients.
The participants had two to six years of tax experience and limited technical backgrounds. They worked in small teams of four to six alongside engineers, using AI-powered "vibe coding" platforms that turn plain English descriptions into working software. A manager from KPMG's tax tech team coached each group through the snags.
What they built was practical stuff: tools that automated compliance processes, pulled data from multiple systems, and generated analytics that used to take hours of manual effort. Brad Brown, KPMG's chief digital officer for tax, said that before the pilot, a tax pro who wanted a specific tool built had to wait in line for engineering resources. Now they could take a first pass themselves and hand off a working prototype for engineers to polish and secure. "Right before your eyes, you're starting to see the evolution of how they were going to deliver services," he said.
KPMG is now considering forming about a dozen permanent teams of around 30 people each, mixing tax staff and engineers, to keep building this way.
The idea here isn't really about tax. It's that the people closest to a problem are now able to build the fix, and the tools to do it are available to basically anyone. If you spend hours every week on some repetitive process you could describe in plain English, you're closer to automating it than you think. That goes whether you're in accounting, operations, client services, or really anything where you keep doing the same sequence of steps and wishing something would just handle it for you.
1. Pick one workflow that makes you groan. Not the most complex thing you do. The most repetitive. The thing where you think "there should be a tool for this" at least once a week.
2. Write out every step in plain language. Open a Google Doc and describe exactly what you do, start to finish. What data goes in, what comes out, where you copy-paste between systems. Be specific about it.
3. Bring it to Claude and ask what it can build you. Paste your workflow description and say "I want to automate as much of this as possible. What's the simplest tool you could build me?" Claude can generate working Google Sheets templates, Notion databases, or lightweight web apps you just open in your browser.
4. Test it on real work and tell Claude what's wrong. The first version won't be perfect. Use it once, note what's off, paste your feedback back in. Two or three rounds of this and you'll have something genuinely useful.
5. Share it with your team. If it works for you, it probably works for the person next to you doing the same thing every week.

OPERATIONS
Jason Staats is a CPA with a YouTube channel called Jason On Firms where he helps accountants run better practices. A few weeks ago he posted a video walking through Claude CoWork, Anthropic's desktop AI agent, doing real bookkeeping on his computer. Over 150,000 accountants watched it in three weeks, which tells you something about how hungry the profession is for this.
The numbers were the headline. He fed CoWork 6,700 bank transactions and a simple Excel template, told it to enter and classify everything, and it finished in 7 minutes and 29 seconds. The ending balance matched the bank statement. The classifications looked like what a human bookkeeper would do. He started smaller first, 67 transactions then 670 then 6,700, scaling up as he built what CoWork calls "skills," which are basically reusable instructions that teach the agent patterns. He made one that builds a vendor map on the fly so Claude doesn't have to think about Home Depot every single time it shows up and just auto-classifies it going forward. That one skill cut processing time on a 670-transaction file from 12 minutes to about 3.
He also showed it matching 41 receipts to their transactions and renaming the files in about 60 seconds. For tax prep, he dropped 57 pages of tax documents into CoWork with an Excel 1040 workpaper and it made 349 entries like a seasoned preparer would. When he planted 10 deliberate errors and told it to check its own work, it caught nine.
The honest part, and what made the video credible, is that Staats was upfront about the limits. CoWork runs locally on your desktop but the AI models are still in the cloud, so sensitive data leaves your machine. His advice was blunt: don't use real client files until the security picture improves. He built AI-generated fake bank statements and receipts for every single demo. The Max plan runs about $200 a month and heavy daily use pushes costs higher, but as Staats put it, humans cost a lot more.
The reason this hit with 150,000 people isn't that bookkeeping is thrilling. It's that most knowledge work has a version of this same problem, a pile of data that needs to be sorted, categorized, matched, or entered somewhere. If you're reconciling invoices, organizing expense reports, processing survey responses, or doing any kind of repetitive data entry, the same approach works. Point an AI agent at the files, give it a template, let it handle the part that doesn't need your brain.
1. Get Claude CoWork from claude.ai on a paid plan. Pro works for light use but anything serious will want Max.
2. Build a test dataset. Don't start with real company or client data. Export a sample spreadsheet or ask Claude to generate realistic test transactions for you.
3. Create your template. Make the spreadsheet or document you want the finished product to look like, with columns, categories, and any classification logic written out clearly.
4. Write your first prompt. Drop in both the source files and the template, then something like "Enter all transactions from these files into this template and classify them to the best of your ability." Start small and scale up.
5. Turn patterns into skills. Once Claude figures out a good workflow, tell it to save that as a skill. Next time you run the same type of task it already knows the playbook and works faster.
OPERATIONS
Tecovas sells cowboy boots. Not software, not SaaS, not anything that sounds like it belongs in an AI case study.
The company has about 60 retail stores and a 10-year track record of doing things the old-fashioned way, which included managing inventory with spreadsheets and manual allocation. Someone on the team would look at what sold where and decide which boots to send to which store. It worked fine until it didn't scale.
So Tecovas tried something simple. They partnered with a company called Invent.AI and let the AI manage inventory decisions for some product categories while humans kept managing others. Same stores, same time period, direct comparison.
The AI-managed categories brought in 9.6% more revenue. They also had a 2% better in-stock rate and a 20% increase in new product sales. The AI was better at figuring out which specific boot in which specific size should go to which specific store to maximize the chance someone actually buys it.
"It's completely changed the way we manage our most important asset in retail, which is our inventory," Kevin Harwood, the company's CTO, said at Shoptalk Spring.
The interesting part isn't that AI beat humans at inventory allocation. It's that Tecovas set up the experiment to find out. They didn't just adopt AI and hope for the best. They ran it side by side with their existing process and measured the gap. That's something anyone can do whether you're managing product inventory, a content calendar, purchasing decisions, or even staffing schedules. Pick a category, let AI handle the recommendations, keep doing the other ones yourself, and compare notes after a month.
1. Pick one recurring decision you make with a spreadsheet. This could be what to reorder, what content to publish, which leads to prioritize, what to schedule. Anything where you're looking at data and making a call repeatedly.
2. Build a simple tracking sheet. Open Google Sheets or Airtable and create two tabs: "AI Recommended" and "My Call." Log the same type of decision in both, along with whatever outcome matters to you like revenue, engagement, completion rate, or response time.
3. Feed your data into Claude and ask for recommendations. Take your historical data, paste it in, and ask Claude to recommend what you should do next based on the patterns. Do this for half your decisions. Make the other half yourself the way you normally would.
4. Run it for 30 days and compare. At the end of the month, look at both tabs. Which set of decisions performed better and by how much? You're not trying to prove AI is smarter. You're trying to see where it adds value for your specific work.
