The Interest and Reminder Statements has to be Enabled. The options to send Reminder Statements and charge interest can be set on Bill Profiles, and overridden in individual Files.
Specify a grace period and threshold AR balance for posting interest and creating mass Reminder Statements.
- For a Bill not fully paid by the end of the Grace Period, choose whether interest starts to accrue as of the Invoice Date or the end of the Grace Period.
- Choose whether interest should be posted to AR or merely appear as a memo item on Bills and Reminder Statements. This affects interest charged from this point forward. If posting interest, only simple interest may be applied.
- The stored Interest Rates are listed, the most recent first. For each Rate, the date that it applies and the annual percentage are shown. To create a new Rate, click New and enter information. Interest on an outstanding Bill is charged at the rate that corresponds to the AR date of the Bill.
- Select the frequency with which interest is calculated: Simple, Compounded Monthly, Compounded Annually, etc. If you chose that interest should be posted to AR, only Simple interest may be used.
Simple interest is calculated as P × I × N, where:
P = principal amount (balance outstanding on Bill)
I = annual interest rate (as a decimal)
N = number of years
For example, a Client has an outstanding Bill for $10,000 and the Interest Rate is 5%. If the Bill is 60 days overdue (calculated from the Invoice Date), then the interest is
10,000 × 0.05 × 60/365 = $82.19.*
