What we validate automatically
Every supplier verified against multiple official sources in real-time.
Real-time RUC status
We verify if the supplier is ACTIVE and LOCATED in SUNAT at the time of each operation. A NOT LOCATED supplier invalidates your deductions.
Coercive Collection List
We cross-check against SUNAT's coercive collection list. Suppliers with enforced debts signal risk of fictitious operations.
El Peruano Publications
We monitor official SUNAT notifications published in the official gazette to detect sanctions or active procedures.
Tax regime
We identify when the supplier's tax regime doesn't match the actual size of their operations — a common pattern in shell companies.
Recent address changes
We alert on suppliers who have recently changed address or economic activity — a red flag for SUNAT.
Retention/Perception Agent
We verify retention or perception agent designation and detect inconsistencies that may affect your obligations.
