Checked against an independent calculation

Questions
Does my financial year have to start in January?
No. Set the first month of your financial year in Settings; every sheet follows it.
How is cash runway calculated?
Cash at bank divided by the average monthly net loss of the last 3 months. If that average is a profit it shows "Profitable".
How many lines can I budget?
30 lines, each typed as revenue, cost of sales, operating expense, other income or other expense.
What if it doesn't work for me?
Email [email protected] within 30 days of purchase. We'll try to fix the problem first; if we can't, you get a full refund through the store you bought from.
