What situations lead to a negative billed amount?

It is possible to see negative bills and negative collections. Both can happen either at the same time or independently. Negative charges occur when more concessions than bills were added for that room, property, or Host during a month. The reasons for adding concessions vary. Negative collections can occur when concessions are added for bills that PadSplit has already paid out. Negative collections can also occur if PadSplit refunds Member money that had already been paid out to the Host.
