Hi, discovered a problem with the Zoho Projects to Books integration involving billing rates for a project.  If a users rate changes mid-project but the user has already been billed, the rate does not change via the integration to Zoho Books.  This causes a lot of problems since staff bill rates can change as a result of events such as promotions unrelated to a project.

I think the underlying issue lies in Zoho Projects and the fact that the rate is not effective dated but any thoughts/advise to avoiding a manual workaround or can this get investigated further.
