About Tekcard Payments

Tekcard Payments is a payment processing and technology company supporting merchants nationwide and a growing ISO/partner channel. We run a fast-paced operation where everyone wears multiple hats and client experience matters.

The Role (Not Generic “Customer Service”)

We’re hiring a Payments Client Services Analyst to support merchants and partners across day-to-day servicing, onboarding coordination, and light operations tasks. This is a B2B, finance-operations style support role—ideal for someone coming from banking, accounting support, fintech, merchant services, or other detail-driven client operations.

You will handle merchant requests, coordinate with internal teams (Underwriting/Risk/Tech/Accounting), and keep accounts moving. You may also support our Premier ISO/Partner channel with status updates, documentation requests, and basic system tasks.

What You’ll Do

• Merchant Support (B2B): Handle inbound merchant questions via phone/email/ticketing—funding/deposit questions, batching, statements, charge schedules, and general account support.
• Partner / ISO Channel Support: Assist partners with onboarding status, missing items, and basic platform/process questions (with clear escalation paths).
• Light Operations / Account Maintenance: Update merchant profiles (bank updates, ownership changes, contact changes), help key/confirm data in internal systems, and ensure clean documentation.
• Issue Triage + Escalation: Identify what’s a client education issue vs. a technical issue vs. a risk/underwriting issue; escalate with clean notes and supporting details.
• Chargeback/Dispute Assistance: Guide merchants on dispute documentation and timelines; route cases appropriately.
• Documentation & Case Notes: Maintain accurate notes, checklists, and follow-ups so nothing falls through the cracks.

You’re a Strong Fit If You…

• Communicate clearly and professionally (written + verbal).
• Are organized and comfortable working multiple queues at once.
• Like structured work: checklists, documentation, clean notes, follow-ups.
• Can learn systems quickly (CRM/ticketing, portals, spreadsheets).
• Can stay calm when a merchant is stressed about money/timing.

Relevant Backgrounds That Translate Well

We’re intentionally trying to avoid “retail-only customer service.” Strong backgrounds include:

• Bank branch operations, deposit ops, treasury support, ACH support
• Accounts receivable / billing support / client accounting support
• Mortgage servicing support / loan operations / escrow processing
• Merchant services support, fintech support, payment operations
• B2B customer support where accuracy + documentation mattered

Requirements

• 1–3+ years in a client-facing operations role (banking, fintech, accounting support, merchant services, etc.)
• Strong attention to detail and comfort with systems + Excel/Google Sheets
• Ability to handle sensitive information with professionalism and discretion

Nice to Have

• Payments/merchant services exposure (funding, batching, statements, chargebacks)
• Experience supporting partners/agents/ISOs (B2B channel support)
• Familiarity with onboarding workflows and verification steps
• Equal Opportunity Employer: Tekcard Payments is an equal opportunity employer.
