Message you can send the client

Thanks for the details. Based on what we have so far, this project will land between $3,150 and $5,300. That covers 2 revision rounds, project management, and a buffer for the open questions. Once we confirm the final scope, I'll send a fixed quote inside that range.

How the range is calculated

  • Low end: best-case hours plus revision hours, plus your calls-and-admin percentage.
  • High end: worst-case hours plus revisions and admin, plus an unknowns buffer of 10% (clear brief), 25% (some gaps) or 45% (vague).
  • Confidence drops when the brief is vague or the high end is more than 2.5x the low end. Low confidence means: ask questions before you quote.
  • Amounts are rounded to figures you'd actually quote. Nothing you type leaves your browser.
