Timeslips doesn't allocate payment by timekeeper. If the bill is undoable, you can undo the bill and enter an adjustment on timekeeper A's time slips, either directly or by going to the fee arrangement and entering an adjustment by timekeeper. 

What if the bill is not undoable?

Then there's no easy way to apply the adjustment specifically to one timekeeper.

Is there a report that is obtainable showing how the write off is applied to each timekeeper?
at least then a manual entry can be made - - Another question - does it apply the write off to the newest time entries and work backwards?  Any help on how it is applied is appreciated.

I believe it allocates payments and write offs proportionately to those who worked on the invoice.  I just don't remember if it does it by percentage of hours or dollars.  My gut says dollars, but you can confirm this yourself.  I.e., if Timekeeper A contributed 10% of the dollars on the invoice, they would be allocated 10% of the payments and write offs.

It is allocated proportionately based on dollars. 

Thank you!  But is there was a payment made on the invoice and the balance written off – would it be 10% on the balance of the invoice or the entire invoice.

Is there anyway of obtaining a report that would show how it is applied.

Similar to the allocation report that you can see how much is given to a person??

Timeslips doesn't allocate payment at the slip level, so it would be against the original invoice amount. Your best bet is probably timekeeper collections which will show how payments were applied by timekeeper.
