This Week in Accounting AI

For 30 years, ERPs have been built for operations, and the general ledger got bolted on as an afterthought. Paul Peterson and Matt Barbieri argue that's exactly why so many finance leaders say "the accounting blows", and why it was never an accountant problem in the first place. Fresh off Rillet Recon 2026, Matt shares what he saw in the room: a community that feels more like an apprenticeship than a conference, a live moment where 100 Claude licenses got handed out on the spot to attendees who'd never logged in, and an AI adoption gap in finance that's now an either-or, with very few in the middle. From there, Paul and Matt dig into the harder questions. Why are companies hiring FP&A teams to do work their accountants are already trained to do? When a growing company outgrows QuickBooks, what's the right way to evaluate an ERP, without starting with the tool? And what does it actually look like to put accounting back at the center of the system, instead of bolted on at the end? A candid conversation about what's broken in accounting systems, what Rillet is getting right, and what every finance leader should be asking before their next system decision.

Paul Peterson and Matt Barbieri make the case that offshoring is a bandaid, not a fix, and that CFOs evaluating accounting partners need to stop asking "how cheap?" and start asking "how are you building intelligence on my business?" They unpack why context is the new competitive advantage in the AI era, why tribal knowledge is the real moat, and the specific questions every CFO should be asking before signing with a firm, from data security to deliverables to who actually owns the knowledge being built.

Tax season is over. The real work is just beginning. In this episode, Paul Peterson and Matt Barbieri pull back the curtain on what actually happens inside an accounting firm during busy season, and why, despite billions spent on software and a wave of AI optimism, this year was harder than the last. They get honest about the hidden costs of AI adoption, why offshoring is a band-aid not a fix, and why the most valuable thing an accountant holds isn't a tax return, it's context.

After 25 years in the trenches together, Paul and Matt get candid about something most firm leaders won't say out loud: accounting has been a soul-crushing profession, and it didn't have to be. Sparked by a piece Paul wrote on the industry's broken culture, this episode unpacks why talented, hardworking accountants have spent careers feeling like they're failing, even when they're not. From the 340,000 accountants who left during COVID to the structural silos that still define most firms today, Paul and Matt trace the roots of the equilibrium problem, too much complexity, too little tooling, and a culture that rewards knowledge hoarding over collaboration. Then they turn to what's changing: why AI won't replace accountants but will finally give them the tools to match their ambition, why context and judgment will become the profession's highest-value currency, and why Wiss is betting big on a different kind of future. This one hits different. Source:  ttps://paulpetersonwiss.substack.com/p/title-why-does-accounting-have-to

In this solo episode, Wiss CEO Paul Peterson gets candid about a question he recently put in writing: why does accounting sometimes feel soulless? Paul draws on real responses from accounting professionals and sobering industry stats to make the case that the profession has a deeper problem than a talent shortage. 340,000 people left the field during COVID CPA exam sittings hit a 20-year low in 2022 50% of accountants under 30 say they regret their career choice Using the Tribal Leadership framework, Paul walks through the five stages of organizational culture and challenges accounting leaders to honestly assess where they stand, and why getting to Stage Four isn't just a culture play, it's a prerequisite for successful AI adoption. He also speaks directly to the people living through the transition right now: doing their jobs the old way while simultaneously piloting new AI tools. This one's a rallying cry for anyone who got into accounting because they wanted to make a difference and is still waiting for the profession to catch up.

Paul Peterson and Matt Barbieri break down the costly mistake venture-backed founders keep making — hiring a CFO before the fundamentals are in place, then watching the org chart balloon from the top down. They unpack the traditional finance build, why it creates mismatched roles and bloated headcount, and why that model becomes even harder to unwind once a company is locked in. The conversation shifts to what a smarter alternative looks like: partnering with a co-sourcing firm that can scale up or down with the business, bring AI-powered workflows to the areas that matter most — AP, AR, revenue — and give your head of finance the tools and intelligence they need to operate as a true strategic partner, not a glorified bookkeeper.

This week, Paul Peterson and Matt Barbieri break down two buzzworthy a16z articles asking the questions everyone in finance is thinking: will AI kill Excel? And what happens to your ERP? Spoiler...neither is going anywhere. Instead, Paul and Matt make the case for an AI layer that works around your existing systems, eliminating the Excel workarounds that have quietly become your source of truth. Matt shares how he uses Claude in Excel daily, why even the most die-hard spreadsheet maven doesn't need to memorize formulas anymore, and how Wiss used AI to finally get HubSpot and their revenue data speaking the same language. The takeaway? Don't wait for your system of record to catch up. Find the pain, get a small win, and build from there, because every week you wait, a competitor isn't. Ready to find your small win?

AI tools are advancing fast, but is your accounting team actually ready to use them? In this episode, Paul Peterson and Matt Barbieri dig into one of the most overlooked obstacles to successful AI adoption: tribal knowledge. Those undocumented, person-dependent workflows that live in people's heads (and endless Excel files) can make or break an AI implementation. They discuss why switching to an AI-native accounting stack isn't enough on its own, how to identify and address the real pain points before bringing in new tools, and what the "see it, fix it" approach looks like in practice. They also share an honest take on how they're using Claude and other LLMs day-to-day, and why every accountant should be experimenting right now. Is your firm ready for what's next?

Everyone's asking how to implement AI. That's the wrong question. In Episode 1 of This Week in Accounting AI, Paul Peterson and Matt Barbieri get into what's really behind the gap between AI adoption and AI results. Matt shares what he's hearing directly from CFOs — companies that have the tools in place but aren't moving the needle. The culprit? Not the software. It's what the software is sitting on top of. Broken workflows, fragmented data, legacy systems duct-taped together. AI doesn't fix bad architecture. It amplifies it. The unsexy truth: before you pick a vendor, you need to run an inventory.
