Our client, an innovative life sciences company, is hiring a Sr. Billing and AR Specialist to join the team!

Position Type: Contract to hire

Location: Houston, TX (Hybrid)

Position Summary

The ideal candidate possesses advanced ERP expertise (NetSuite preferred), thrives in high-volume environments, and maintains a strict standard of accuracy. Because this role directly intersects with revenue generation, the candidate must possess the professional confidence and presence to collaborate effectively with both Client Services/Sales team, stepping into the role as a trusted partner and subject matter expert from day one.

Core Responsibilities

• Multi-Product Billing Execution
• Own and execute full-cycle billing operations across multiple distinct product lines, issuing invoices aligned with complex contract terms, schedules, and deferred revenue policy.
• Audit operational triggers, billings, and system data (since the ERP and operational platforms do not connect) to prevent data disconnects and ensure billing accuracy.
• Validate and review general ledger (GL) coding and class segment assignments.
• Perform comprehensive monthly reconciliations of the Accounts Receivable sub-ledger to the General Ledger, identifying and resolving variances immediately.
• Maintain robust AR aging metrics, cash forecasting tools for customer payments, and other customer KPIs/dashboards for leadership review.
• Analyze Month-over-Month (MoM) revenue and billing trends to identify, flag, and investigate unusual fluctuations or transactional "swings."
• Serve as the primary point of contact for external audits regarding revenue and AR; proactively compile, format, and deliver required PBC (Provided by Client) schedules and supporting data.
• Manage proactive collection efforts for outstanding accounts, balancing assertive cash recovery with a high standard of professional courtesy and customer relationship management.
• Investigate, track, and resolve billing disputes, unapplied cash balances, and payment "bounce-backs" or technical portal errors.
• Partner cross-functionally with Customer Support and Operations teams to ensure customer inquiries are handled seamlessly and workflows remain un-bottlenecked.
• Apply daily cash receipts (ACH, Wires, Credit Cards) accurately against open invoices, eliminating manual "suturing" gaps.
• Serve as the primary finance liaison to the Sales/Client Services team, confidently navigating billing questions, contract disputes, and complex client onboarding workflows.
• Maintain a firm, confident, yet collaborative approach when enforcing internal compliance controls, collection efforts, billing schedules, and documentation requirements with the commercial team.
• Facilitate regular syncs with Client Services to proactively manage account updates, minimize communication gaps, and eliminate bottlenecks before they reach the client level.

Job Requirements & Qualifications

• Education: Bachelor’s degree in Accounting, Finance, or Business Administration preferred (or equivalent combined experience).
• Experience: 3–5+ years of progressive experience in corporate billing, collections, and AR analysis. Experience in healthcare, laboratory billing, or complex subscription/service models is a major plus.
• Systems Expertise: Advanced proficiency in a major ERP (NetSuite highly preferred). Experience utilizing billing engines, client portals, and Excel for heavy data analysis (VLOOKUPs, Pivot Tables, Sumifs, Manual Calculation tuning).
• Core Competencies:
  • Strict attention to detail with an implicit need for "transparent figures" and clear audit trails.
  • Strong understanding of GAAP accounting principles surrounding revenue recognition, deferrals, and accruals.
  • Exceptional written and verbal communication skills; ability to hold firm boundaries while maintaining operational equity and team camaraderie.
  • Self-starter mindset who actively references historical data and past processes as supplemental training tools to master the business logic.
  • High Professional Confidence & Initiative: A self-starter who is willing to take full ownership of the AR department, voice opinions, challenge discrepancies, and confidently guide external clients and internal sales teams toward standard processes.
