Once you raise a provisional residential invoice, any changes to the financial assessment history won't be reflected on the invoice unless you perform another Invoice Preview. This is by design; otherwise, the concept of the provisional invoice would be pointless. Ideally, authorities should review and sign off on provisional invoices before generating invoices.
However, if a client is no longer due for charges due to changes in their financial assessment, the preview won't delete the existing provisional invoice, so it will still be included in the preview results.
Performing a preview for just one client does delete the provisional invoice for that client.
Therefore, a scenario can occur where a client is due charges, and a provisional invoice is raised during the invoice preview. If the client’s financial circumstances then change so that they are no longer due any charge, a further Invoice Preview won't delete their provisional invoice. When you perform an Invoice Generate, a "permanent" invoice will be created for the client based on their previous financial circumstances.
After performing an Invoice Preview but before generating invoices, if a client’s financial circumstances change and they are no longer due any charge, you should perform another Invoice Preview for that single client before running an Invoice Preview for all clients again. This will ensure the provisional invoice is deleted.
