New to Cairnworks? Grab the free Quarterly Tax Set-Aside Calculator. It is a single-sheet, plain-math tool for figuring out what to set aside each quarter. $0 at checkout with email capture. It is not tax advice.

Cairnworks is a small template studio. We build no-nonsense spreadsheet systems for people who run their own money: freelancers, side-hustlers, Etsy sellers, and short-term-rental hosts. Every product is macro-free. It works in Excel 2016+ and Google Sheets. Each product ships with clearly-labeled sample data so you can see every report working. Buyers get free v1.x updates. Spotted a bug or want a category added? Message us through Payhip and we will ship it in the next update.
