Job Overview

We are seeking a dynamic and results-driven Client Service & Sales Supervisor to lead our Client Services team through strategic account management, innovative workflows and effective team leadership. The Client Service & Sales Supervisor is a critical leadership role within the Company’s Client Service & Sales department. This position owns the day-to-day performance of Client Services team responsible for managing active client accounts, processing daily orders and supporting sales growth across 7+ product brands.

This role bridges the gap between the Client Services team and the Sales team, handling escalations, coaching team members, monitoring performance, and personally managing the Company’s highest-value and most complex client relationships. The ideal candidate is an experienced B2B client service or sales professional who leads by example, thrives in a fast-paced results-driven environment, and brings a track record of building and maintaining high-functioning teams. A successful candidate will possess experience in leading teams to deliver exceptional service to B2B clients for wholesale products through effective order management, identifying bottlenecks or challenges and developing solutions that work and ultimately translates to an increase in sales.

Client Relationship Management

Identify dormant or declining accounts and develop targeted re-engagement strategies.
Stay current on the full Hydronix product catalog across all 6-7 brands; maintain awareness of pricing tiers, promotions, and competitive positioning.

Cross-Departmental Coordination

Act as the primary liaison between the Client Service & Sales team and Production, Warehouse, Logistics, and Purchasing.
Escalate and resolve cross-departmental issues that impact order fulfillment, RMA resolution, or client satisfaction.
Coordinate with Logistics on special shipping requirements, Florida warehouse approvals, and container arrival timelines.
Partner with Purchasing to streamline RMA factory credit requests and ensure timely resolution of defective product cases.
Conduct regular meetings with other departments to address inventory issues and develop client services processes to ensure smooth and accurate outcomes.

Process & Operations Oversight

Develop and maintain written Standard Operating Procedures (SOPs) for order processing, RMA management, client outreach, and escalation workflows.
Identify inefficiencies in current processes and implement improvements in collaboration with the team.
Ensure the CRM/Order Management system is properly maintained, with all client interactions, open cases, and account notes accurately logged by all team members.
Identify areas of the improvement within our technology resources and utilizing Ai tools wherever possible.
Monitor order accuracy, RMA cycle times, and same-day processing rates; address root causes of errors or delays proactively.

Qualifications

Bachelors Degree in Business Administration, Supply Chain or related field preferred or equivalent combination of education and experience.
7-10 years of experience in B2B wholesale client services, inside sales, or customer success with at least 5 years in a supervisory or team lead capacity.
At least 3 years of hands-on experience building inventory workflows (stock, transfers, backorders) that support efficient, client-ready order fulfillment.
Proven track record of managing large, multi-account portfolios in a product-driven B2B environment.
Experience with NetSuite CRM.
Strong organizational skills with the ability to manage multiple priorities, deadlines, and personalities simultaneously.
Must have a solid understanding of wholesale distribution and inventory processes.
Excellent verbal and written communication skills — professional, clear, and solutions-oriented at all times.
Demonstrated ability to coach team members and drive measurable performance improvements.
Experience developing or improving SOPs for client service or order management workflows.

Preferred

Experience in water treatment, water filtration, industrial distribution, or a related specialty product industry.
