I’m the founder of a +700 firm private community that’s shaping the future of small-firm ownership for the better. In this episode, I break down the 25 Claude Cowork features accounting firms need to understand, from basic setup and model selection to projects, connectors, skills, plugins, scheduled tasks, browser use, and security controls. I explain why Cowork should be treated less like a side assistant and more like production infrastructure for firm workflows, while also showing how firms can dial in security based on what they are comfortable deploying today. 💰 (Sponsor) MakersHub helps accounting firms automate complex accounts payable work using AI, especially when invoices, receipts, projects, line items, and payments get messy. Jason highlights how it extracts detailed invoice data, supports foreign exchange across IBAN countries, handles international vendor details, and now includes Canadian workflows like GST/PST handling and tax codes by line item. It is positioned as a strong fit for firms dealing with ugly AP, itemized bills, multi-currency payments, and high-volume invoice work.
