I'm not sure what's going on or how best to describe it but hoping someone can help! We have interest set at 10% compound, billed after 30 days. Sometimes a client will pay their bill after the 30 days is up, but will only pay the principal and not the interest charges. In that case, we just write off the interest. But for some of our clients, interest is continuing to accrue even though the principal is paid and the interest accrued has been written off. To give an example:
Client was billed $2290. She did not pay on time, so on her next bill, there was a past due charge for $2290 plus an interest charge of 20.08. She then paid the original amount of $2290. I did a write off for $20.08 so her balance was $0. The next month, no new charges, she had a bill for $4.39 in interest. I wrote it off again. This month, she has a bill for $0.25 in interest. Her pre-bill shows that the "total overdue" is $15.69 but when I go to the A/R screen, it shows she has a $0 balance due.
1) How can I stop this from happening and correct it?
2) How can I change the template so that we have simple interest instead of compound interest? I think this will solve it in the future but I'm not sure how to change it so that the change affects all our clients (who are all on the same billing settings).
