What I'm looking for

I’m looking for remote Accounts Receivable opportunities with US companies, where I can drive collections, dispute resolution, and cash application improvements—reducing DSO, increasing cash flow visibility, and automating workflows with SAP and VBA.

I’m an Accounts Receivable Consultant with 8+ years of experience leading end-to-end AR operations for multinational and Fortune 500 clients, including Big 4 Deloitte. I focus on improving cash flow through collections strategy, dispute resolution, and accurate billing-to-cash execution.

At Ankura Consulting Group, I manage full-cycle AR for high-value global clients across the US, Middle East, Germany, Hong Kong, and Australia, integrating international accounts into corporate AR platforms to improve cash flow visibility and reporting accuracy. I supervise high-volume invoicing and payment processing, run aging and reconciliation, and drive automation using SAP, VBA Macros, and Lean Six Sigma Green Belt methods.

Previously at Deloitte and TCS, I handled large AR portfolios (about $55M at Deloitte and ~$35M at TCS) while delivering measurable results—streamlining collections and reducing overdue accounts and DSO (including a stated 20% reduction at Deloitte) through dispute resolution, pre-litigation actions, and executive escalation readiness. I also supported teams with SOP development, mentoring, and hands-on training to strengthen AR performance, customer satisfaction, and operational excellence.
