1. Start in the product itself. QuickBooks' guided setup and in-app tooltips cover the basics you'll use constantly: invoicing, categorizing transactions, running a report. Use the free trial if you don't have an account yet.
2. Use Intuit's own free tutorials. QuickBooks' support site has structured, free lessons organized by task, not just a FAQ dump. It's the most directly relevant free resource because it's built for the exact version you're using.
3. Watch the official YouTube channel. Intuit runs its own QuickBooks YouTube channel with playlists for QuickBooks Online basics, specific features, and year-end tasks. Useful when you want to see a screen, not just read about it.
4. Check for free local workshops. SCORE, local SBA chapters, and community colleges frequently run free or low-cost small business bookkeeping workshops that cover QuickBooks fundamentals alongside general bookkeeping.
5. Use the QuickBooks Community forum when you're stuck on something specific. It's searchable, and most specific "how do I do X" questions have already been answered there by someone who hit the same wall.
