If you are looking for something like a "Static" LN invoice, there are a couple approaches.

BOLT 12, which has been implemented in c-lightning, is a way to essentially refer a payer to the node that is to be paid, in order to request a new invoice. While the BOLT 12 offer can be static and reusable — it always refers to the same node — the payee can generate new invoices on the fly when requested, allowing for much more flexibility, Provoost explained.
