Michalina Ziętek

I’m a finance operations professional with experience across accounts receivable, US tax compliance, and data quality in large-scale corporate environments. I’m comfortable working with high-volume data, ERP systems, and cross-functional teams, turning operational details into reliable outcomes.

As an Accounts Receivable Specialist at Motorola Solutions, I manage AR portfolios up to $5M+ for US Public Sector accounts, ensuring data accuracy and timely revenue recognition. I handle account reconciliations, resolve billing discrepancies, maintain customer master data in Oracle Greenfield and Salesforce CRM, and support contract verification across multiple states, including required tax adjustments and credit holds.

Before that, at Accenture, I was a Tax Operations & Compliance Analyst, performing data quality reviews for international markets and escalating inconsistencies to support fraud prevention. I processed high-volume W-9 and W-8 documentation for a major US technology client, verifying multi-market requirements using English, Spanish, and French—always with a strong focus on process optimisation, audit readiness, and continuous learning.
