Buyer, Merchandiser or Planner? How Fashion's Commercial Roles Differ

The commercial side of fashion

Designers decide what a product looks like. The commercial team decides how much of it to make, where it is sold, at what price, and when it should be marked down. These are some of the most numerate jobs in fashion, and some of the most misunderstood, because the same title can mean different things at a department store, a direct-to-consumer brand and a resale marketplace.

This guide explains the core roles and how they work together. Where we quote pay, it comes from ranges published by employers on listings on our job board in November 2026. Ranges change, so treat them as examples, not benchmarks.

Buyer

A buyer selects the products a retailer will sell. At a multi-brand retailer, that means visiting markets and showrooms, choosing styles from other labels and negotiating terms. At a brand that sells its own product, the buying role often sits closer to product development, choosing which styles from a range go into production and in what depth.

Day to day, buyers review sales data, build assortments, raise and track purchase orders, and work with suppliers on deliveries. Assistant buyer is a common entry point. As an example, Rent the Runway listed an Assistant Buyer role in Brooklyn at $48,527 to $60,659 a year, focused on market preparation, purchase orders and tracking deliveries.

Merchant and merchandiser

"Merchant" and "merchandiser" are used in two quite different ways:

• Product merchandising decides what the range should be: how many styles, which price points, which categories need building or cutting. Quince, for example, listed an Associate Merchant role for women's activewear in San Francisco at $94,000 to $125,000 a year.

• Visual or site merchandising decides how product is presented, whether on a shop floor or a website. E-commerce site merchandisers arrange product pages, collections and sort orders using sales and traffic data.

Read the responsibilities, not the title. If a listing talks about "range plans" and "margin", it is product merchandising. If it talks about "homepage", "collections" or "floor sets", it is presentation.

Planner

Planners own the numbers behind the range: how much stock to buy, how to split it across channels, stores and sizes, and how to react when items sell faster or slower than expected. The work is spreadsheet- and system-heavy and involves forecasting, open-to-buy budgets and in-season replenishment.

Everlane, for instance, listed a Senior Planner for women's apparel in Los Angeles at $81,000 to $120,000 a year. Allocation analysts, who distribute stock to individual stores, are a frequent entry route into planning.

Category manager

At marketplaces and platforms, a category manager often combines buying, merchandising and commercial strategy for one product area: sourcing supply, setting promotions, and working with marketing on demand. StockX listed remote Category Manager roles for apparel and for sneakers at $120,000 to $130,000 a year.

How the roles fit together

In a typical season, merchants set the shape of the range, buyers commit to specific styles and quantities, and planners make sure the money and stock add up. Product development and sourcing teams then turn those decisions into finished goods. In smaller companies, one person may do all of this.

Getting in

Most entry-level commercial roles ask for strong spreadsheet skills, comfort with numbers and a clear interest in product. Retail experience counts, as does any role where you analysed sales. Useful steps:

• Learn the basic metrics: sell-through, weeks of cover, margin, markdown and open-to-buy.

• Show you can explain a decision with data. A one-page example from a shop job or a personal project can help.

• Search our board by job area for buying and merchandising or planning roles, and read several listings to see which tasks come up again and again.
