“Always Be Closing” (“ABC” of selling)

“Always be closing” (the ABC’s of selling) dates in print to at least 1950. The phrase was popularized by David Mamet’s awarding-winning play, Glengarry Glen Ross, which opened on Broadway in 1984—and the critically acclaimed 1992 film of the same name. Mamet’s drama involved shady real estate sales, but “always be closing” has also been used in the sales of financial products.
   
 
Wikipedia: Glengarry Glen Ross
Glengarry Glen Ross is a 1982 play written by David Mamet. The play shows parts of two days in the lives of four desperate Chicago real estate agents who are prepared to engage in any number of unethical, illegal acts—from lies and flattery to bribery, threats, intimidation, and burglary—to sell undesirable real estate to unwilling prospective buyers. The play draws partly on Mamet’s experiences of life in a Chicago real estate office, where he worked briefly in the late 1960s. The title of the play comes from the names of two of the real estate developments being peddled by the salesmen characters, Glengarry Highlands and Glen Ross Farms.
 
Mamet had sent the play to Harold Pinter for comment, who admired it and, as an associate director to Peter Hall, recommended it for production. As a result the world premiere was at the National Theatre in London on September 21, 1983, where Bill Bryden’s production in the Cottesloe was acclaimed as a triumph of ensemble acting.
 
The play opened on Broadway on March 25, 1984 and closed on February 17, 1985. The production was directed by Gregory Mosher and starred Joe Mantegna, Mike Nussbaum, Robert Prosky, Lane Smith, James Tolkan, Jack Wallace, and J.T. Walsh. The production was nominated for four Tony awards including Best Play, Best Director, and two Best Actor nominations for Robert Prosky and Joe Mantegna, who won the production’s one Tony.

...a practical sales maxim- ‘Always Be Closing’. The essence of salesmanship, in other words, is to imply both that the customer is getting a bargain and that he or she is in a position to take advantage of the seller.
