Payment in Blood was described by Italian film historian Roberto Curti as Castellari's "official" debut, as it was the first time the director was credited as a director after going uncredited on films such as Some Dollars for Django and A Ghentar si muore facile.^[4] The film was shot in Spain with Castellari intentionally trying to duplicate the style of a film that made an impression on him, Sidney J. Furie's The Appaloosa.^[4]

Payment in Blood passed the Italian censors on 29 March 1967.^[1] It was first released in 1967.^[5]

In contemporary reviews, "Murf." of Variety described Payment in Blood as "a gamy slapdash and overly violent Civil War oater drama, made by crude Italian film hands and probably exported in hopes that names of Edd Byrnes and Guy Madison might have the b.o prospects."^[2]
