Insurance Claim- Do rebuild yourself- Payments

[Mak K.]

I have a water damage claim on a property and insurance decided to shell out $5k (Upfront) initially and $3k (recoverable depreciation) once work is done and invoice is submitted.

If I plan to do the work myself, how does it work? I do not have any invoices to submit to claim the $3k. Do I generate invoice for myself and submit it?
