The flow is the same even when the event is not
You are not hosting the same party twice, so an invitation tool that only understands one occasion is a tool you will outgrow by the next season. The useful version is one maker that handles whatever you are throwing. The path never changes: describe the event, get a page drafted, add your names, publish, and share the link. What differs from gathering to gathering is the content of the page, not the way you build it.
The thread running through every use is the guest list. It is not an afterthought bolted on at the end; it travels with the invitation from the start, so a reply is not just a yes but a yes recorded against the right person.
