With a synths, snares and organ backing, the mid-tempo song's lyrics center on blocking out drama and negativity in favor of professional and financial success.

During a 2014 interview with Billboard, Fantasia explained that her fifth studio album The Definition Of... (2016) would expand on the "rock soul" sound that she introduced on her previous release Side Effects of You (2013).

[5] Fantasia described the recording process for the single, and the album as a whole, as entailing a large amount of personal sacrifice and serving as her opportunity to "open the door to a new chapter of life".

[2] The three-minute, 26-second pop, R&B and soul song was written in common time in the key of D-flat major with a slow tempo of 135 beats per minute.

[6] Elias Leight of Vogue described the song as an "iconoclast" with a "de rigueur quiver of programmed hi-hats" and a "wormy synth melody and bass line" which could appeal to listeners of hip hop music.

[8] Idolator's Mike Wass described the song as a "catchy mid-tempo anthem" and its lyrics, such as "Bitch, no time for the haters tripping", as exemplifying that "Fantasia has always been the realest".

[11] According to Time's Maura Johnston, the song's lyrics are a "kiss-off" and "a salvo aimed right at any gossipmongers who fill their hours with loose talk".

[14] The following day, the song premiered on Fantasia’s Vevo channel,[15] and explicit and clean versions were digitally released at the iTunes Store.

[22] A music video of an acoustic version of "No Time for It" premiered on Fantasia's Vevo on March 24;[23] the following day, it was released on the iTunes Store.

[25] B. Cakes of Soulbounce.com called the video personal and intimate, "a candid woman-to-woman (or woman-to-man) talk with one of her detractors", and praised the acoustic remix as keeping the focus on its lyrics.

[12] Reviewing the album for the Knoxville News Sentinel, Chuck Campbell praised "No Time for It" as "smoothly arranged and spiked with her vocals" and suggested it as an answer for listeners "tired of all life's drama".

[35] Kevin Apaza of Direct Lyrics criticized the song as safe and predictable, called its production dated, and felt that Fantasia was "sleeping on her laurels".

Apaza suggested that Fantasia or RCA release a remix with Kelly Rowland or another female R&B singer to "prevent this single [from] fall[ing] quick into oblivion".

[36] In Entertainment Weekly, Chuck Arnold criticized "No Time for It" for "gloss[ing] over the grit of Fantasia's voice" and cited it as an example of the album's uneven sound.
