How do I use AI to figure out which of my products or services make me the most money?
AI tools like Claude and ChatGPT can analyze your product or service profitability if you give them your prices, costs, and sales volumes — paste in a simple table and ask "Which of these is most profitable and why?" For more automated analysis, tools like QuickBooks Online, Shopify Analytics, and Square Analytics already calculate gross profit per product and can surface this insight without any manual prompting.
Many small business owners are surprised to find that their best-selling product is not their most profitable one. Volume is flattering; margin is what pays the bills. The simplest way to start is to build a quick table: list every product or service, its selling price, its material cost, and a rough estimate of how many hours of labor it takes. Paste that table into Claude (claude.ai) and ask "Calculate the gross margin for each item and rank them from most to least profitable." The AI will do the math and flag anything below a healthy margin threshold for your industry. The insight that changes most business owners' behavior is the contribution margin ranking — not gross margin %, but actual dollars contributed per month (gross profit x units sold). A product with a 40% margin on $20 items contributes less per month than a product with a 25% margin on $200 items if volumes are similar. Ask Claude: "Which item contributes the most gross profit dollars to my business per month?" That answer tells you which product line to protect and promote. For ongoing tracking without manual analysis, both Shopify (shopify.com) and Square (squareup.com) have built-in analytics that show profit per product, profit by location, and profit trend over time — as long as you've entered your costs in the platform. QuickBooks Online (quickbooks.intuit.com) has a "Profit and Loss by Class" report that works similarly for service businesses tracking different service lines. Once you know your most profitable products, use AI to help you act on the insight. Ask Claude: "I have three services — consulting, training, and implementation. Consulting has the highest margin. Write me 3 ideas for how to get more consulting revenue from my existing customer base." You'll get concrete, actionable ideas like upsell scripts, package redesigns, and referral ask templates — turning a data insight into a revenue action in minutes.
