Before you send your manuscript
- If your manuscript contains a table of contents, remove it before uploading. Sandrine. generates one automatically with the correct page numbers.
- Remove the title page, half-title, copyright and dedication if already typed — Sandrine. lays them out cleanly.
- No manual page numbers (“— 12 —”), no hard page breaks, no inline colors.
- Keep one consistent chapter heading format throughout (e.g. “Chapter 1”, “Chapter 2”…).
These points help Sandrine. read your book correctly. If something doesn't match, fix your file and re-upload — it takes two minutes.

I've pre-checked what's typical for your genre. Add or remove anything that doesn't fit.
