I received an invoice for $2500 from a vendor that I have coded as follows:

Parts                    $2000  

Travel Exp            $1000

Repairs               ($500).  credit for overcharge on previous months repairs

When I generate my P&L for the month, Quickbooks has split every single expense in every category.  The negative repair is split into 5 amounts and every other expense is split into 2 amounts.

Can someone tell me why it is doing that?
