My dad’s old-school bookkeeping habit
For as long as I can remember, my father has run a small business. And for just as long, he has kept his books the old-fashioned way: every sale gets written down by hand. It works well enough for tracking daily revenue, but when tax season rolls around, his accountant needs that data in Microsoft Excel. My dad, who never grew up around computers, has never learned how to use a spreadsheet.
For years, his solution was paying someone to manually type each handwritten entry into a digital file. It got the job done, but it added a recurring cost he wanted to eliminate. He just couldn’t figure out how.
The moment that sparked the idea
Last week, I visited home and found my dad hunched over his notebook, writing out yet another day’s worth of sales. I tried teaching him a few Excel basics. To his credit, he picked them up quickly. But the data entry itself was still eating up hours — typing rows and rows of numbers isn’t something you master overnight, especially if you didn’t grow up with computers.
That’s when it clicked: why not use Anthropic’s Claude AI to take the manual work off his plate entirely?
Turning handwritten bills into a spreadsheet with Claude
I got to work. I set up a simple Claude project and gave it instructions: take photos of my dad’s handwritten bills and turn them into properly filled-out Excel data. To show the AI exactly what I wanted, I built a sample spreadsheet and filled in the first few rows manually. I then uploaded that sample sheet along with photos of his handwritten records.
Claude filled in the rest. Data that would have taken my dad hours to type by hand took only minutes. Yes, the AI made occasional mistakes — a misread number here, a skipped line there. But all my dad had to do was cross-check the output. That is far easier than entering hundreds of rows from scratch.
The best part? Claude projects remember the setup. Now all my dad has to do is open the project, create a new chat, upload his spreadsheet and handwritten bills, and Claude handles the data entry from there. No formulas to memorize. No formatting to figure out. No one else to pay.
Is the AI tradeoff worth it?
I’m not someone who thinks AI is an unquestionable good. The natural resources that data centers burn through, and the price increases we’re seeing across consumer electronics, are hard to ignore. I don’t always believe the benefits match what we’re giving up.
But then I look at my dad. He’s 65, has never been comfortable with computers, and always assumed tools like Excel were simply not for him. Now, with a setup that took me an afternoon to build, he’s using AI to run a part of his business that used to cost him time and money every week.
I don’t think this cancels out the bigger concerns around AI. But it’s hard to dismiss what it has done for one person who never thought this kind of technology was within his reach. The joy I saw on his face when he completed his first Excel sheet is something I will always hold in my heart. For that one moment, at least, the tradeoffs felt worth it.
