Wondering is someone has a workaround or an idea to solve this seemingly simple issue.

I need the ability to apply a vendor credit (one journal entry without matching it to an invoice) for the discounted amount each month.  For example if I received 1% on $1000 spent for the month.  A vendor credit of $10 needs to be applied to the vendor without matching to an invoice.  I also get a volume discount lump sum on some months and that needs one journal entry to deduct from the bill. If I recicved $283.41 volume discount I need the ability to credit that to the vendor without matching to a invoice. 

In simply or sage, I would just enter a negative bill as a discount or rebate. done
