So wouldn't this be:

* you have an invoiceX from CompanyA to CompanyD
* CompanyY creates invoiceY referencing invoiceX to CompanyB
* CompanyB pays CompanyA for invoiceY thus acquiring invoiceX
* CompanyB creates invoiceZ referencing invoiceX (that it now owns) to CompanyD

End result should be CompanyA's books being balanced and CompanyD's books being
unbalanced to the tune of invoiceX and thus requiring payment from CompanyD to
balance.

The link between the invoices is kept via invoiceY and invoiceZ.

Now I'm a newb to bookkeeping so hope that's both right and makes sense. :)
