Q: Excel or Google Sheets?
Both. It's an .xlsx file — open it in Excel, or in Google Sheets choose File → Import → Upload. Every formula works in either.
Q: Do I need to know accounting?
No. If you can type a number into a cell and pick from a dropdown, you can run Stashly. The math is already built in.
Q: Is this tax advice?
No. Stashly estimates what to set aside based on a rate you choose. It is not a CPA — confirm your actual obligations with a tax professional.
Q: How much should I set aside?
A common rule of thumb is 25–30% of net profit. The Settings tab includes a built-in "how to pick your %" guide.
Q: What if it's not for me?
Email within 30 days and you get a full refund. No questions.
Q: Any ongoing fees?
None. You pay once and own the file. No subscription, no account, nothing leaves your computer.
Q: Is my financial data private?
Completely. Stashly lives on your computer or your own Google Drive. No account, no login — nothing is ever uploaded to us.
Q: Can I reuse it every year?
Yes. Set the tax year in Settings and keep going, or duplicate the file for a clean slate. Free updates included.
Q: I'm outside the U.S. — can I use it?
Tracking works anywhere. The quarterly due dates and 30% default are U.S.-oriented, but you can set your own rate.
Q: Where should I keep my tax money?
In a separate savings account — ideally high-yield — and move your set-aside % there every time you get paid.
