Job Description:

Job Description Job Description Who We Are Waste Solution Services (WSS) helps multifamily and commercial portfolios lower and stabilize waste spend by sitting between clients and haulers to audit invoices, optimize contracts, right-size service, and manage vendor issues. Our story is simple: NOI lift cost predictability fewer operational fires. The Role (What You'll Do) We're hiring an Audit & Margin Analyst to be the primary guardian of financial accuracy and margin across our billing ecosystem. You will build the technical infrastructure to detect expense/billable variances, manage the lifecycle of rate increases, and translate complex audit findings into clear, customer-facing savings reports. Core Responsibilities Financial Forensic Auditing: Perform deep-dive audits of vendor invoices against customer billables to identify discrepancies, overcharges, or missed revenue opportunities, documenting findings in a structured, repeatable way. Advanced Modeling & Tooling: Design and maintain complex Excel and BI templates, formulas, and queries (e.g., Nested Ifs, XLOOKUP, Pivot Tables, Power Query, VBA) to automate the identification and tracking of variances. Dispute Resolution & Corrections: Partner with Billing Specialists and internal stakeholders to investigate variances, provide supporting documentation, and ensure accurate corrective actions on invoices. Rate Increase Management: Build and manage a standardized process for “allowable and necessary” vendor rate increases, including analyzing vendor-side increases, reviewing customer contracts, and calculating the impact on gross margin before implementation. Cross-Functional Coordination: Act as the central hub for contract and pricing data, working with Sales, Operations, and Procurement to gather service details, update assumptions, and align on changes that affect billing and margin. Sales Commissions Calculation: Develop and maintain automated models to calculate sales commissions based on verified revenue, deal attributes, and commission plans; validate payouts against billing data, resolve discrepancies with Sales leadership, and ensure timely, accurate processing aligned with payroll cycles. Process Improvement: Identify root-cause billing errors, recommend workflow changes, and partner with leadership to implement process improvements that prevent recurring financial leakage. Customer Savings Reporting: Produce clear, professional, recurring customer-facing savings reports that quantify realized cost reductions, recovered margin, and billing optimizations, and present insights in a way that supports customer retention and trust. What Success Looks Like (Outcomes) Measurable reduction in unbilled revenue, overcharges, and margin leakage across audited portfolios. A consistent, documented process for rate increases that protects gross margin while honoring customer agreements. Recurring savings and variance reports that customers can easily understand and that highlight ongoing financial value. Clear visibility for leadership into the size, sources, and trends of billing variances and recovered margin. Who You Are You have a strong analytical mindset and enjoy drilling into granular data while keeping sight of big-picture financial impact. You’re comfortable reading and interpreting complex contracts and turning them into clear rules for billing and rate changes. You communicate clearly, can explain complex findings to non-technical stakeholders, and are comfortable presenting to leadership. You are organized, can juggle multiple concurrent audit cycles, and thrive in a cross-functional, fast-moving environment. Requirements 2–4 years in financial analysis, auditing, revenue assurance, or billing operations. Bachelor’s degree in Accounting, Finance, Economics, or a related field. Experience with general bookkeeping and familiar with reviewing profit & loss (P&L) statements, including reconciling revenue and expenses, interpreting margin impact, and tying audit findings back to financial performance. Advanced Excel proficiency (Nested Ifs, XLOOKUP, Pivot Tables; Power Query or VBA a plus). Comfort working cross-functionally with Sales, Operations, Procurement, and Billing. Preferred Experience (Nice to Have) Experience in waste management, logistics, or brokerage environments. Exposure to BI tools such as Tableau or Power BI. Experience with commission structures, quota attainment tracking, or sales performance data. Familiar with Salesforce, Quickbooks, and Netsuite. Why WSS Direct impact on revenue integrity, margin protection, and customer value realization. High-visibility role that interacts with leadership and multiple departments. Opportunity to directly contribute to the development of the revenue assurance backbone of a growing, niche service business Notice: WSS does not accept unsolicited contact from recruiters, agencies, or third-party vendors.
