I want to bump this topic, as I would like this feature to disable partial payments. I am experimenting accounting for a real estate client in Quickbooks. However, the this becomes a problem if we cannot disable partial payments. For example in a situation where a tenant decides to pay $1 for $1,000 rent, some states will recognize the landlord as accepting of the month's rent and disallow the ability to evict. Essentially, someone could get away with paying $1 a month for rent if the landlord decides to use this feature, but many landlords won't due to this. If however, QBO does allow disabling of this and more landlords pick up on this, I would bet QBO can make some nice change on those interchange fees. *wink wink*.
