Monitor supplier confirmations and production timelines, proactively tracking status updates and escalating potential fulfillment delays to buying managers and supply chain partners to minimize out-of-stocks.

Coordinate inbound logistics and transportation exceptions with vendors, 3PLs, and warehouse teams to resolve short shipments, overages, damages, and discrepancies, and to optimize delivery windows.
Maintain and reconcile purchase order and invoice discrepancies by communicating with vendors and accounts payable, submitting claims or credits where necessary to protect gross margin.
Negotiate routine commercial terms with suppliers for price breaks, payment terms, minimum order quantities and lead-time improvements under the guidance of senior buyers, documenting agreements and updating supplier records.
Assist in vendor onboarding and qualification processes, gathering required documentation (COI, W-9, quality certificates), completing vendor setup in the ERP, and ensuring compliance with corporate vendor policies.
Collaborate with merchandising and marketing on promotional planning, ensuring promotional orders are placed timely, inventory is allocated correctly, and markdowns are minimized through pre- and post-promo analysis.

Analyze historical sales trends and market intelligence to identify slow-moving items, clearance opportunities and potential sourcing alternatives that improve turnover and reduce carrying costs.
Coordinate sample flows and quality inspections with vendors, QA teams and technical design to ensure product specifications, labeling and packaging meet compliance and brand standards prior to mass production.

Administer promotional and markdown approvals, ensuring proper PO adjustments and financial tracking so promotional impact is reflected accurately in financial reports.
Support cross-functional projects such as ERP upgrades, EDI integrations or supply chain process improvements by providing buyer perspective, testing transaction flows, and documenting standard operating procedures.
Maintain a clean and auditable record of purchasing transactions, contracts, and communications to support internal audits and ensure compliance with procurement policies.
Respond to internal stakeholders’ ad-hoc data and purchasing requests by extracting PO, inventory and vendor data, building pivot reports, and presenting findings that support quick commercial decisions.
Assist in managing private label or vendor-managed inventory programs by coordinating order schedules, forecasts, and replenishment thresholds to ensure optimal stock levels.
Keep abreast of market trends, commodity pricing shifts, competitive assortments and regulatory changes affecting product sourcing and recommend adjustments to buying strategies.
