What qualifies
Company records associated with Warsaw, Poland whose business descriptions match “accounting firm business process outsourcing companies” by meaning at the Exact setting.

Match quality
RevenueBase's August 25, 2026 study assessed 4,198 description/company pairs across matching settings. The publisher reports 86% good or better at Exact.

Read the full methodology: how the lists are built and what the study measures.
