Claude: Ops

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.'

Redline a vendor's standard OEM agreement with Claude for the first three rounds, then have a lawyer do the final check

jedberg regularly negotiates OEM agreements with vendors that mostly use the same template and draw the same objections. They tried Claude first, and their lawyer was impressed that it found things the lawyer had missed. jedberg then used Claude to redline that type of contract, and the other side remarked that the lawyer had been surprisingly thorough. The lawyer did the final check and by then basically said it looked good, and jedberg saved a lot of money by doing the first three rounds with Claude.

Sort a year of mixed Amazon business purchases into QuickBooks categories with Claude, including the fiddly split transactions

badlibrarian runs a business and sometimes buys things on Amazon. At tax time they used to search for the big business items and categorise them in QuickBooks Online until they gave up, using a janky browser plugin and two monitors full of Excel windows. Now Claude does it and doesn't give up, despite QuickBooks being slow. It will even click 19 times to split a transaction because they'd put a router and shampoo in the same Amazon cart one night in February 2025.

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.

Ask Claude whether to convert an LLC to an S Corp, and miss that NYC taxes make it cost more

mikeocool asked Claude about converting their LLC to an S Corp. Claude said it was a great idea and estimated how much they would save in taxes. Their accountant said it would actually cost more, because of how New York City taxes S Corps. They hadn't told Claude they lived in NYC, because it didn't occur to them that it mattered. Their takeaway: tax questions are full of details like this, often subtler than where you live.

Recreate and resend an urgent client invoice from a phone in a roller coaster queue with Claude

A client called Alper Ortac on a family holiday at Europa Park needing an invoice urgently for their end-of-year accounts. With no laptop, Ortac opened Claude on their phone in a roller coaster queue, attached the last invoice and asked it to recreate it. Claude wrote and ran a Python script that produced a replica of the PDF, then changed the invoice number, billing period and costs as asked. Ortac drafted the email, attached the new invoice and sent it in roughly 20 minutes, right before boarding.

Turn a PTA's bank exports into year-end charity accounts in four minutes with Claude

Pete Hickerton, chair of their school's PTA, wanted to save the treasurer an evening on the year-end accounts. The job meant exporting bank transactions, categorising everything, reconciling and formatting it for the Charity Commission. They gave the bank exports to Claude, and four minutes later had a set of accounts ready to upload. Claude explained what it had done, flagged where it had checked the formulas and showed the reconciliation. Hickerton and the treasurer went through it looking for errors and found none.
