Bought on Etsy or Gumroad?
You can also message the JobCostLab shop on Etsy, or reply to your Gumroad receipt. Include the product name so we can find your order.
What to include
- Corrections: which calculator, what you entered, what it showed, and what you expected. If the math is wrong, it gets fixed.
- Requests: your trade and the number you wish you could calculate faster. New calculators come from these.
- Spreadsheet support: the product name and whether you are in Excel or Google Sheets.
What we do not do
We do not give legal, tax, insurance or accounting advice, and we cannot tell you what to charge in your market. The tools show you your cost; the price is your call.
