If it is important to your friend, most funeral details can be pre-planned (obituary, service, music, flowers, plot, coffin, vault, marker, etc.) and the expenses can be prepaid.
For a bachelor uncle in his 90s for whom my sister and I were POAs, we had everything prearranged and prepaid. The only expense we had after his death was the fee for opening and closing of the grave.
Your friend is truly lucky to have you.
