Spreadsheets built like test procedures
I spent 15 years in power-plant construction, commissioning and test engineering, after serving as a nuclear-trained electronics technician in the U.S. Navy. That work runs on checklists, verified numbers and paperwork that holds up when someone asks for it.
I bring the same approach to the spreadsheets in this shop. They’re built for two kinds of people:
• Small contractors and trade businesses that quote from a notepad, chase insurance certificates by email, or track change orders in their head.
• Executors settling an estate, who need to account for every dollar in and out and show that it balances.
Each workbook comes with a filled-in sample, so you can see it working before you add your own data. Built-in checks flag a bad entry before it reaches your totals. The executor workbook’s accounting has to balance to the cent, and it tells you when it doesn’t.
Every template is tested against real scenarios before it’s listed: in Excel on Windows and Mac, in Excel for the web, and in Google Sheets. I use AI tools when building and testing the workbooks, and I check every formula myself against test cases.
The files are yours to keep, with no subscriptions and no macros. Use them in Excel (Windows, Mac or web), or make your own Google Sheets copy from the link in your download.
These are recordkeeping tools, not legal, tax or insurance advice.
