The Rules of Acquisition were a numbered series of aphorisms, guidelines, and principles that provided the foundation of business philosophy in Ferengi culture. They were first written ten thousand years ago by Gint, the first Grand Nagus. In the mid-22nd century there were 173 rules, and by the 24th century there were 285. Commentaries existed for the Rules. In theory, every Ferengi business transaction strictly follows all 285 rules. (ENT: "Acquisition", DS9: "Rules of Acquisition", "The Maquis, Part I")
There was also a short-lived revised edition of the Rules written by Grand Nagus Zek after having his state of mind changed by the Bajoran Prophets. These rules were almost complete opposites of the original rules and promoted honesty and charity. After Zek recovered, he ordered all copies of the new rules to be destroyed. (DS9: "Prophet Motive")

- ↑ As late as 2151 the rule was quoted as being slightly different. "Never allow family to stand in the way of profit" (where profit replaces opportunity). (ENT: "Acquisition")
- ↑ Legends of the Ferengi concludes Rule #16 with "...until a better one comes along."
- ↑ Legends of the Ferengi concludes Rule #31 with "...insult something he cares about instead."
- ↑ Brunt stated a variation of this Rule (without referring to it by number) with: "It's never too early to suck up to the boss".
- ↑ Quark has stated a corollary: "only from a distance, the closer to the front lines, the less profitable it gets"
- ↑ Although spoken before the production staff's creation of the Rules of Acquisition, Par Lenor stated something quite similar to this rule: "Peace is good for trade ... unless you happen to be an arms merchant!"
- ↑ 7.0 7.1 Rule of Acquisition #95 was quoted as Rule #45 in ENT: "Acquisition". It might be possible though, that in the roughly 200 years between the two episodes, the arrangement of the Rules of Acquisition slightly changed. Alternatively, it may have been decided that the rule bears repeating. Indeed, this may be self-referential.
- ↑ This rule was interrupted before it could be finished.
- ↑ Though not given a number, this rule was clearly official, among the first 173, and considered "the most important one" by Krem
- ↑ In DS9: "Body Parts", it is suggested in a dream of Quark's, that the Rules of Acquisition themselves are merely guidelines, and the book was mislabeled by Gint so as to sell more copies than the "Suggestions of Acquisition." However, this may be no more than Quark trying to justify breaking rule #17, since this rule is obviously higher than ENT's "original" 173 rules. It could also be noted that the Grand Nagus has the power to change the Rules of Acquisition, so it is still possible this rule changed position over time (DS9: "Prophet Motive").
- ↑ Personal rule of Quark's. Rom noted there was no such rule, to which Quark replied that there should be.
- ↑ May be a purely fictional rule, as it was quoted by Neelix, who had no previous contact with Ferengi, and it did not exist by the time the target Ferengi became stranded in the Delta Quadrant.
- ↑ Arridor and Kol taught the Takarians this saying. It was not stated whether it was an official rule or not.
- ↑ According to Arridor.
- ↑ Invented by Arridor.
- ↑ This saying was quoted by Brunt to Quark. It is unknown whether it is an official rule or not.
- ↑ Not quoted word for word, but when Sisko asks if such a rule exists, Quark acknowledges that there is. Quark may be referring to the apocryphal Rule 218 (see below).
- ↑ A personal rule quoted by Nog despite its direct contradiction to rules 94 and 229.
- ↑ As told to Odo by Quark when the latter illegally uses replicators in empty crew quarters. He seems to have been paraphrasing the apocryphal Rule 52 (see below).
- ↑ This un-numbered "rule"'s provenance derives merely from Janeway quoting it as something "the Ferengi say". It may not, therefore, be a genuine Rule.
- ↑ Rom says this to Quark when urging him to complete a very important mission that could end with the two being killed. From the implicit understanding Quark displays, and the lack of prior reference to any "written" materials, it's likely that this is in fact a Rule, probably referring to the finality of a business contract, here used out of this original context.
