Scale catering recipes for 25–30 people up to hundreds with ChatGPT and Claude

Brian Reilly, co-owner of Arlington's Catering and Historic Venue in Springfield, took a six-week small-business AI workshop sponsored by Innovate Springfield. Reilly now uses ChatGPT and Claude to make routine checklists, such as cleaning procedures, and to scale recipes built for 25–30 people up to, say, 330. Reilly says accuracy depends on the input. When Reilly fed it information inaccurately, those mistakes were caught 'pretty quickly', and now Reilly screenshots the recipe into the tool instead to avoid user error. 'It might take a time or two, but it's been pretty accurate.'

Turn a retailer's carton labeling rules into a label file with Gemini

Jamie Kim, owner of the granola company Jamie's Farm in New York, uses Gemini to work through big retailers' dense delivery-guideline PDFs, where a mistake can mean major chargebacks. When one retailer required every shipping carton to be labeled with its number and destination warehouse, Kim asked Gemini to help generate a custom CSV file for the label template and point to online label-making software, turning a full day's work into one hour. Gemini in Sheets also helped write formulas for a spreadsheet tracking inventory, sales and cost of goods.

Have Claude draft replies to a small brand's customer messages, warranty claims included, with a human approving each one

idopmstuff runs several small consumer brands. For the most recent one they acquired, customers got in touch through Facebook and Instagram comments and messages as well as email, so they had Claude build an app that pulls those messages in as they arrive and drafts a reply, including any actions needed, for them to edit or send. Their edits feed back into its playbook, and it has got pretty good. It handles warranty claims (ask for a photo of the damage and the order number, create a replacement order, email a confirmation) and most common questions. Every reply is still approved by a human, though they plan to let it handle common cases on its own soon.

Run a restaurant's back office through an OpenClaw agent: supplier price-change alerts, invoice uploads and a fairer tip split

Christopher Thépot runs restaurant operations in Madrid and spent a month using OpenClaw. The agent answers point-of-sale questions over WhatsApp and combines supplier invoices, sales data, recipes and inventory counts to track waste and what's missing. It flags supplier price spikes; two pricing mistakes caught so far directly affected the P&L. It also pulls supplier invoices from their inbox into the accounting software's scanner, saving one to two hours a week, though they're still fine-tuning that. They used it to design and test a new tip policy in under an hour: 80% stays with the shift and 20% goes to a pool split by hours worked.

Turn a photo of a cafe's daily inventory sheet into shopping lists for three suppliers with a custom GPT

Cole Morgan runs a small cafe with no single major supplier, so they drive to three stores. Staff fill in two paper inventory forms each day and upload them to Slack, and turning those into a checklist for each store took 2–10 minutes. An off-the-shelf OCR tool that worked well cost over $250 a month, and a Python script they had ChatGPT write wasn't accurate enough. So they built a custom GPT, 'C&K Inventory Manager', trained on a spreadsheet of every item and its vendor. Now they upload the sheet photo and get a checkbox list grouped by vendor, ready to paste into Obsidian. It asks about items missing from the sheet, such as whole milk. Accuracy improved with GPT-4o with no change to the instructions, though it sometimes asks too many questions and they have to tell it to just output the list.

Auto-coach sales reps from call recordings with Zapier Agents

Find, negotiate and review a small office lease with Codex

Codex found a 74 sq ft commercial lease near the poster's kids' school, negotiated the terms and reviewed the contract; the poster found it cheaper than a coworking desk.

File subcontractor invoices into 30 job folders automatically with ChatGPT

Morgan Sterling runs Beach Cities Builder, a construction company in Hermosa Beach, California, and gets several subcontractor invoices a day across roughly 30 active job folders. Each one used to mean opening the invoice, working out the project, typing the details into Zoho Books and filing it in the right Google Drive folder. After a friend suggested it could be automated, Sterling asked ChatGPT and ended up with a script hooked up to email that puts every invoice in one folder, reads it, identifies the job and moves it to the right place. The first version took about two hours to build; Sterling says it's now effectively 100% accurate and saves roughly 5–6 hours a week. Sterling also built a script that adds any forecast with more than a 40% chance of rain in the next seven days to the calendar.

Turn a sourdough hobby into a licensed microbakery with Gemini

Inna Pak, a stay-at-home mom in San Francisco's Richmond District, turned to AI to learn how to make a sourdough hobby a business. 'When I was doing my license, I don't think I could actually do it without the A.I. help,' Pak said. Pak used Gemini for everything from how to create labels for the loaves to ingredient measurements and baking schedules, and even the bakery's name, Plum Perfect. Since opening in May, Pak sells 10 to 20 loaves a week through a Saturday pop-up and online orders, and dreams of a brick-and-mortar bakery.
