@engineer,
Thank you for the reply!
the invoice was from 2019
so inv date=6/30/19, first due month is 7/30/19. From 7/30/19 to now 7/15/2020, How to set up the formula for the past months and accrued interest on that?
july 2019: 10,200 * 1.5% = 153
aug 2019: (10,200 + 153)* 1.5% = 155.30
sept 2019:
to june 2020 is twelve months
Again thank you in advance!
