Journal politics aside, most authorship conflict is a planning failure. Someone assumed analysis credit; someone else thought “helping with references” was acknowledgment only. The fix is not a longer email thread — it is an agreed roster before work begins.
On Scauthor you can build an author team by ORCID when posting a project. Lead and co-authors appear on the paper even if they have not joined Scauthor yet; verified users receive a consent request when they sign in.
Use CRediT-style roles where they clarify contribution: conceptualisation, methodology, formal analysis, writing. You do not need perfect taxonomy on day one, but naming roles beats naming feelings.
The corresponding author should be explicit before submission. Trackers, journal correspondence, and ethics queries flow to that person — ambiguity here delays real work.
Scauthor stores authorship metadata with the project, not in a side spreadsheet that only the PI can edit. When a co-author opens the paper workspace, they see the same roster you see — that alignment is the point.
