RUC Status: ACTIVE but NOT LOCATED
We detect suppliers with unconfirmed tax address — a serious irregularity signal that can invalidate your deductions.
SUNAT Coercive Collection List
We verify if the supplier has debts enforced by SUNAT, indicating financial problems and risk of fictitious operations.
El Peruano Publications
We cross-check against official SUNAT notifications published in the official gazette to detect sanctions or procedures.
SMV vs Declared IGV Discrepancy
We compare income reported to SMV with the declared IGV pattern to identify suspicious inconsistencies.
Incompatible Tax Regime
We identify when the supplier's tax regime doesn't match the actual size of their operations.
Recent Address Changes
We alert on suppliers who have recently changed address or economic activity — a common pattern in shell companies.
Loss of Good Taxpayer Status
