Purpose

To provide accurate, timely administrative support to the wholesale merchandising function, owning the day-to-day data, order and systems processes that keep wholesale trading running smoothly across our UK, EU and US accounts.

• Wholesale Account Support
  • Support the day-to-day administration of key wholesale accounts including JD Sports and Footasylum, spanning their UK, EU and US operations.
  • Prepare and process account orders, ensuring correct pricing, delivery windows and allocation.
  • Produce and maintain order confirmations, line sheets and account-specific reporting.
  • Liaise with account contacts and internal teams to resolve order, delivery and data queries.
  • Support the onboarding of new products and ranges into accounts.
• Systems & Integrations
  • Act as a confident day-to-day user of NetSuite ERP for order, stock and data management.
  • Maintain product and order data within Shopify, ensuring it stays aligned with NetSuite.
  • Build and maintain reports and dashboards in PowerBI to support trading and account reviews.
  • Work closely with 3PL warehouses to ensure orders, dispatches and stock movements are accurately reflected across systems.
  • Apply working knowledge of Warehouse Management Systems (WMS) to track stock, dispatch and fulfilment status.
  • Identify, flag and escalate system errors, integration breaks or data mismatches.
• Stock & Intake Support
  • Support intake tracking and the flow of stock from suppliers through to wholesale dispatch.
  • Monitor stock availability against confirmed orders, flagging shortfalls and risks.
  • Assist with the allocation of stock to accounts in line with agreed priorities.
  • Maintain accurate intake, delivery and dispatch records.
• Reporting & Analysis
  • Produce regular and ad hoc reports on orders, stock, intake and account performance.
  • Support weekly trade and account reviews with accurate, timely data.
  • Help surface trends, risks and opportunities through clear, reliable reporting.
  • Maintain the trackers and reporting tools used across the wholesale team.

Skills & Experience

• Minimum 1 year of experience in a merchandising, wholesale or stock/order administration role (sportswear, footwear or fashion preferred).
• High level of accuracy and strong attention to detail when keying and managing large volumes of data.
• Comfortable working across multiple systems – exposure to NetSuite ERP, Shopify B2B, PowerBI or WMS platforms is a strong advantage.
• Good Excel skills (formulas, pivot tables, lookups).
• Well organised, with the ability to manage a high-volume workload and consistently meet deadlines.
• Clear communicator, comfortable liaising with both external accounts and internal teams.
• Proactive, dependable and eager to develop.
