$ methodology --read

Every dollar figure on this site is either source-linked to a vendor's public pricing page or labelled illustrative. Here is how we keep that promise.

$ answer --question="Where does every number on this site come from?"

Vendor figures come from each vendor's public pricing page, captured with a verified-on date. Project bands come from vendor-published cost guides (Astra, Cobalt, Bishop Fox) and labelled as such. We never infer a price for a vendor that does not publish one. We never use a third-party estimate as a source for a vendor's own pricing.

Vendor pricing changes faster than any single-quarter re-verification can catch. If you see a stale figure, email Oliver at oliver@digitalsignet.com and we will re-verify within five working days.
