Accounts Payable Supervisor

About the role

BerryDunn is seeking a qualified Accounts Payable Supervisor to lead the delivery of accounts payable services on behalf of multiple outsourced accounting clients. This individual will supervise a team of accounting assistants, own approval and payment workflows across multiple client environments, and serve as the day-to-day client relationship owner for AP. The ideal candidate brings exceptional attention to detail, sound judgment around approval authority, and the ability to communicate clearly and professionally with client stakeholders ranging from office managers to business owners. They will handle highly confidential information across multiple client entities, prioritize and reprioritize a fast-moving workload, and coach team members to a high standard of accuracy and service.

Responsibilities

• Serve as the primary AP point of contact for multiple assigned clients, building trusted relationships and ensuring service levels are consistently met.
• Lead client onboarding for new AP engagements, including chart of accounts mapping, vendor master migration, and SOP documentation tailored to each client.
• Own the invoice approval workflow across multiple client engagements—reviewing coding, GL classification, supporting documentation.
• Review and release client payment runs (ACH, wire, check, and vendor portals), confirming vendor banking details, duplicate-payment checks, and proper segregation of duties for each client.
• Oversee client AP inboxes and escalation queues, ensuring same-day triage.
• Train staff on client-specific procedures, systems, and approval requirements; build cross-coverage so no single client is dependent on one team member.
• Aid with annual 1099 preparation and filing across the client portfolio, including vendor master data cleanup and W-9 validation throughout the year.
• Maintain and continuously improve AP policies, procedures, and internal controls; document SOPs and identify automation opportunities across the practice.
• Operate fluently across multiple client accounting and AP platforms (including QuickBooks Online, Sage Intacct, Bill.com, RAMP and similar tools).

Requirements

• 5+ years of progressive AP experience, including at least 2 years in a lead or supervisory capacity; experience in an outsourced accounting, client-services, or multi-entity environment strongly preferred.
• BS in Accounting, Finance, or Business; equivalent professional experience considered.

Qualifications

• Exceptional attention to detail.
• Strong understanding of AP internal controls, segregation of duties, and approval authority frameworks.
• Hands-on experience across multiple accounting and AP platforms (e.g., QuickBooks Online, Sage Intacct, Bill.com, RAMP); ability to learn new systems quickly.
• Working knowledge of 1099 reporting and vendor compliance.
• Proven client service skills, including the ability to communicate clearly and professionally with client stakeholders at all levels, manage expectations, and resolve issues.
• Excellent written and verbal communication and interpersonal skills.
• Ability to handle confidential information with discretion and maintain strict data segregation across client engagements.
• Advanced Microsoft Excel skills (pivot tables, lookups, reconciliations); strong overall Microsoft Office proficiency.
