What is the difference between a buyer and a range planner in fashion retail?

A buyer is primarily responsible for selecting and purchasing products from suppliers, negotiating prices, and ensuring the right products are available at the right time. A range planner, on the other hand, focuses on the strategic composition of the product range, including the mix of categories, price points, and quantities, as well as managing the critical path and inventory levels. In many organisations, these roles overlap, but the buyer is more supplier-facing while the planner is more data and analysis-driven.

How do I calculate the gross margin for a fashion product?

Gross margin is calculated as (Selling Price - Cost of Goods Sold) / Selling Price, expressed as a percentage. For example, if a dress sells for £100 and costs £40 to produce, the gross margin is (£100 - £40) / £100 = 60%. This metric is crucial for assessing profitability and making pricing decisions.

What is a critical path and why is it important in fashion buying?

A critical path is a timeline that outlines all key stages in the product development and delivery process, from initial concept to final delivery to stores. It includes milestones such as design approval, sample production, bulk manufacturing, and shipping. It is important because it ensures that products are available for the intended selling season, helps coordinate teams, and identifies potential delays that could impact sales.

How do fashion buyers forecast trends?

Fashion buyers use a combination of methods including analysing historical sales data, attending trade shows and fashion weeks, monitoring social media and street style, reading trend reports from agencies like WGSN, and collaborating with designers. They also consider economic and cultural factors that influence consumer preferences. The goal is to predict what customers will want to buy in upcoming seasons.

What is the role of a supplier in the buying process?

Suppliers are the manufacturers or vendors that produce the products a buyer selects. They play a critical role in providing samples, negotiating prices and lead times, ensuring quality control, and managing production. A good buyer-supplier relationship is built on trust, communication, and mutual benefit, as suppliers can offer insights into new materials, production capabilities, and cost-saving opportunities.

How do I decide how many units of each product to order?

Order quantities are determined by a combination of factors including historical sales data, trend analysis, store capacity, and financial targets. Buyers use tools like open-to-buy (OTB) budgets, which allocate spending across categories, and consider sell-through rates and stock turn targets. The goal is to balance having enough stock to meet demand without over-ordering, which can lead to markdowns and reduced profitability.

Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for demonstrating a clear distinction between multiple buying environments (e.g., independent boutique, e-commerce, concession, multi-brand store) and their distinct commercial drivers.
Credit accurate mapping of the buying cycle stages—analysis, planning, selection, negotiation, delivery, and performance review—to a specific fashion business context, showing cause and effect.
Reward application of a retail buying strategy (e.g., open-to-buy, margin planning, forward buying) to a case study, including rationale within a contemporary global context such as sustainability or digital transformation.
Look for evidence of how merchandising data (sell-through rates, stock turn, margin mix) directly informs and is informed by the buying role, with a critical link back to customer demand.

Assessment Guidance

Guidance for achieving higher grades

💡Anchor all theoretical discussions in real-world examples: reference a specific retailer’s buying team structure or a recent range plan to demonstrate applied understanding.
💡Use the language of the industry—OTB, WSSI, sell-through, SKU rationalisation—correctly and in context to show professional competence.
💡For scenario-based questions, explicitly link the buying decision to the merchandising KPI it aims to improve (e.g., linking increased option count to uplift in conversion).
💡Structure assignments to first define the retail environment, then map the cycle, then propose a strategy, and finally show merchandising integration, ensuring logical flow and cross-referencing.
💡Use real-world examples: When answering questions, reference specific fashion brands or case studies to demonstrate your understanding of how concepts apply in practice. This shows depth of knowledge and critical thinking.
💡Show your calculations: For any numerical questions, always show your working out step-by-step. Examiners award marks for correct methodology even if the final answer is slightly off.
💡Link theory to commercial outcomes: Always explain how a concept (e.g., range architecture) impacts key performance indicators like sell-through rate, gross margin return on investment (GMROI), or stock turn. This demonstrates a holistic understanding.

Common Mistakes

Common errors to avoid in your coursework

Confusing merchandising with visual merchandising; treat merchandising solely as product display rather than the analytical planning of stock flow, allocation, and profitability.
Failing to differentiate the buying cycle for seasonal fashion versus fast-fashion/agile supply chains, assuming all retails follow identical timelines.
Overlooking the impact of digital buying environments—online-only retailers, social commerce, dropshipping—and focusing only on brick-and-mortar contexts.
Mixing up forward cover and open-to-buy budgets, or applying them without adjusting for promotional periods and markdowns.
Ignoring global factors like exchange rates, trade tariffs, or ethical sourcing when building a buying strategy, limiting the analysis to domestic perspectives.
Misconception: Buying is only about selecting products based on personal taste. Correction: Buying is a data-driven process that involves analysing sales data, market trends, and customer feedback to make objective decisions that align with the brand's commercial strategy.
Misconception: Range planning is the same as merchandising. Correction: While related, range planning focuses on the strategic selection and timing of products, whereas merchandising involves the visual presentation and promotion of those products in-store or online.
Misconception: A higher markup always means higher profit. Correction: Markup is only one factor; profit depends on volume sold, costs, and margins. A high markup on slow-selling items can lead to markdowns and reduced overall profitability.
