Why buy it instead of building it
Checked against an independent calculation
Before release, every formula is compared with a separate model, including edited data and deliberately bad entries.

Questions
What if the rent changes mid-year?
End the old tenancy row on the change date and add a new row with the new rent; both count for the year.
Rent due on the 31st?
It falls on the last day of shorter months automatically.
What if it doesn't work for me?
Email altaitoondev@gmail.com 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.
