Depends a little bit, and the following is a bit off the cuff.....but:

Are you going to continue to bill this project under the new Rate Y, AND continue to split the bill between the client and Insurance Co?  Do you need to keep track of how much each owes you going forward?

Scenario 1: NO, billing is all done, just need to apply the credit and Ins Co $$ and get the client to pay remainder.

- Apply the Ins Co $$ as a regular payment with a nice description of same

- Create a Credit (or Write Off) on original Client for the total difference in rate that has already charged.

-That will leave a remainder that is the client's portion at the lower rate.

Scenario 2: YES, billing wll continue at new/lower rate and want to track the two balances for each 

- Change the rate rules to make sure new slips are billed at Rate Y going forward.

- Create a second Timeslips Client entity to keep track of what the Ins Co will owe/pay, and set up a Split Billing Rule to have the new charges at Rate Y be split between original Client Account and Ins Co.

- Create a Credit (or Write Off) on original Client for the total difference in rate that has already charged.

- Create a second Credit (or Write Off) for how much the Ins Co is going to pay of the total due at the new rate (I would do a second credit because it will just be easier to follow and understand later)

- That should leave the Original Client with their own balance due.

- On the new Insurance Company client.  Issue an Invoice A/R transaction to charge their account for the amount you credited the Original Client above.  I.e, previously billed, but going to be paid by Ins Co.

-Issue a payment on the Ins Co account to pay the previous balance.

Hope that helps.
