When someone else takes over a gig from you, it's always wise to make arrangements in advance should anything go wrong. To help you, we've prepared a sample invoice, so your replacement can send it to you after the gig is done. We have also prepared a model agreement that you can enter into with your replacement. This way, both parties have something to fall back on, and you can avoid any uncertainties.

The invoice and model agreement can be downloaded at the bottom of the article. You might want to use a PDF viewer application to sign the document.
