The directory's largest letter — twenty-three sales roles, from assistant to showroom management
Letter S is the heart of the sales and selling directory, for the simple reason that the industry names most of its selling jobs with the word sales itself. Twenty-three role descriptions begin with S: the career ladder from assistant through executive to manager, the showroom roles, and the row of product specialisms — branded, licensed, children's, maternity, men's, women's and extended-size selling — that this category exists to explain.

The general roles form a ladder: the sales assistant supports a team, the sales executive owns accounts and a target, the sales consultant sells by advising, and the sales manager leads the sellers — with showroom sales and its manager covering the selling floor where ranges are presented. Around that ladder sit the specialisms, each the same selling craft aimed at one product world: knits, wovens, menswear and womenswear at management level; branded and licensed apparel; childrenswear and kidswear; maternity, big and tall and plus size; and sportswear.
Start from the kind of selling, not the title. Product specialists should find their category in the list; readers aiming at the general ladder should read assistant, executive and manager in that order, because each page assumes the one below it. The forecaster page stands slightly apart — it is the category's numbers role, predicting the sales the other twenty-two roles are hired to make.
Twenty-three: sales assistant, big and tall, branded apparel, childrenswear, consultant, executive, forecaster, kidswear, licensed apparel, major accounts, manager, the four manager specialisms (knits, menswear, womenswear, wovens), maternity, menswear, sales person, plus size, womenswear, showroom sales, showroom sales manager and sportswear sales — all listed above.
Because employers name selling jobs from the word sales: sales assistant, sales executive, sales manager and their product specialisms all file under S. Other letters hold roles named differently — retail and regional under R, international under I, men's specialisms under M.
With the Sales Assistant page — the entry-level support role from which most wholesale selling careers begin — then the Sales Executive page, which describes the full account-owning role the ladder leads to.
