About the Role

The Billing Specialist I owns defined billing workflows at Indeed Flex, ensuring client invoicing complies with rate, tax, and invoicing rules. This role operates at the intersection of Money, Revenue, Operations, and Support, involving hands-on daily billing tasks, resolving client queries, and investigating discrepancies to identify root causes and document findings for business action. The position supports financial controls, contributes to month-end reporting, and aids in scaling billing processes in a fast-paced, high-volume environment.

Responsibilities

Own defined billing workflows, such as a client segment, invoice run, credit card billing, or weekly reconciliation, ensuring compliance with rate, tax, and invoicing rules.
Raise accurate, complete, and timely client invoices by consolidating time and attendance (T&A), rate, and worker pay data, and resolve client billing queries efficiently.
Raise invoices for credit card customers and collaborate with credit card providers to ensure correct data capture.
Run weekly reconciliation of portal client data and invoicing data against worker pay and timesheets.
Ensure clients are set up and maintained correctly in billing systems, including rates, tax treatment, and billing details.
Investigate billing discrepancies independently to find root causes, resolve them within the level of authority, and document pain points and control gaps with sufficient evidence for action.
Balance live billing work with analysis, staying close to daily billing to confirm the effectiveness of process and tooling changes.
Improve discrepancy handling by clarifying root causes, processing correct adjustments and credit notes, and reducing repeat exceptions.
Protect billing SLAs and invoice-run timelines during volume spikes and month-end without compromising operational or analytical work.
Map workflow and system friction across ACP/OMS, NetSuite, Salesforce, and related tools clearly for others to act upon, and contribute requirements and failure-mode evidence to shape billing tooling and automation improvements.
Apply payroll, tax, invoicing, and accounts receivable (AR) rules correctly while identifying process design breakdowns.
Build basic billing reports, including introductory SQL, and independently check data accuracy from T&A through to billing and payroll.
Test billing automation and AI tools in production-like conditions, distinguishing genuine defects from user error.
Maintain QA gates for owned billing workflows, including client setup and rate-card accuracy, pre-issue invoice checks, and adjustment and credit-note checks, to prevent known defects from reaching clients or the ledger.
Onboard and mentor associates during their ramp-up, and guide short-term overflow help during invoice runs and month-end to maintain team output reliability.
Share discrepancy findings with Credit Control, Payroll, Finance, Revenue/Account Management, and Operations early enough to prevent handoff failures.
Support internal and external auditors with process walkthroughs and queries.
Support the finance team with month-end reporting and reconciliation.

Requirements

Relevant accounting or billing experience, including owning complex billing adjustments or reconciliations.
Part-qualified or finalist of professional exams (CPA or equivalent).
Strong working knowledge of invoicing, rate, and tax (including VAT) rules, and their application to staffing or high-volume billing.
Advanced Excel / Google Sheets skills (pivot tables, lookups, reconciliations).
Working knowledge of SQL (introductory level), or a clear willingness to learn it quickly.
Experience with finance and CRM systems such as NetSuite and Salesforce.
Structured problem-solving skills: ability to trace discrepancies to their root cause and document control gaps clearly for non-finance audiences.
Comfortable testing automations and AI tools, and writing clear defect reports and requirements.
Experience onboarding, mentoring, or coaching peers.
Strong attention to detail and numeracy; a self-starter who works well under pressure.
Strong communication skills with internal partners, clients, and auditors.
Highly organized, with strong prioritization skills across both operational and analytical work.
