Free wins here: Overleaf is free, venue templates are free, and LaTeX is free. Most researchers never need to pay for formatting.

Worth paying for:

  1. Overleaf premium: only if you need version history beyond 24 hours or tracked changes at scale. Most labs do not.
  2. A formatting service: for the final camera-ready polish before a journal submission, when the stakes justify it.
  3. Reference manager premium (Zotero is free; EndNote/Mendeley premium rarely needed).

Not worth paying for: template marketplaces selling premium versions of free venue templates, and AI formatters that promise to convert Word to LaTeX perfectly. They do not.

Keep every version of the formatted paper; reviewers sometimes ask what changed between submissions.

Review the dashboard every Monday; the ritual matters more than the tool. Sources: IEEE, ACM The expensive formatting mistake is not a tool, it is time: reformatting a finished paper for a different venue's template the night before the deadline. Pick the venue first, format once.
