Ferengi ranks was a hierarchical collective command structure, utilized by the Ferengi military, represented by various combinations of rank insignia, including pips and braids worn on the Ferengi uniform, combined with a small green tattoo worn on the right lobe.
The tattoo worn by Ferengi officers consisted of the Ferengi logo, and depending on rank, additional chevrons next to the logo. For example, in many cases, a DaiMon's tattoo consisted of the logo and two chevrons. (TNG: "The Last Outpost", "The Battle", "Peak Performance", "The Price", "The Perfect Mate", "Rascals")
Omag, also wore the same number of insignia, but did not wear a tattoo.
Another indication of rank were thin silver stripes at the lower part of the sleeves. Again, higher-ranking officers wore two stripes on each sleeve (Omag and Solok, for example); while lower ranking officers, like Qol wore one each and Ferengi of the lowest ranks wore no stripes (Nibor, Kol).

Aside from the frequently referenced "DaiMon", no other rank titles were ever stated to correspond with the evidential attempt to indicate such a hierarchy.
At one point during TNG Season 1, Mike Okuda drew up concept art, dated 13 August 1987, that in accordance to their purported "mercantile preoccupation", gave the following tattoo-based rank designations:
- No chevron indicated "crewmembers"
- One chevron indicated a "salesman, third class" (using Letek as an example)
- Two chevrons indicated a "salesman, second class" (using Taar as an example)
- Three chevrons indicated a "salesman, first class (assistant manager)"
The last version of the tattoo was never seen on the show, but was indicated to be reserved for "future big guys". (Star Trek: The Next Generation - The Continuing Mission, p. 62)
