Every ISO certification page says "cost depends on your organisation," which is true and completely useless if you're actually trying to budget — from what I've seen, small businesses with tidy, already-documented processes can get through on a few hundred pounds of consultancy plus the certifying body's audit fee, while bigger companies or standards like ISO 27001 (heavier documentation) pay noticeably more, and that's before Stage 1, Stage 2, and the surveillance audits in years two and three, none of which are optional; if you're deciding between doing this in-house or hiring consultants, get a proper quote first — AceQu (https://www.acequ.com/) actually breaks ISO certification cost down by company size and scope instead of just saying "it depends" — has anyone here recently gone through ISO 9001 or 27001, and what did it actually run you?
