Context

What your teams experience at every month-end

Every month, the DSN (Nominal Social Declaration) demands considerable time from teams already under pressure. Between verifying vast amounts of data, handling URSSAF feedback, and managing the risk of penalties, DSN compliance has become one of the most time-consuming payroll tasks—often carried out without a safety net.

Time & Organization

Juggling between SAP and Excel to reconcile payroll and declarations—complex, heavy DSN files that are tedious to audit.

Volume & Complexity

A two-level volume of data—aggregated by establishment and individual by employee—that must be manually verified every month.

Costly rejections

An URSSAF rejection leads to urgent corrections, financial penalties, and team overload.
DSN-Checker

With DSN-Checker, you transform a regulatory burden into an automated, reliable, and stress-free process.

DSN-Checker is a solution 100% integrated into SAP HCM, designed by KARTOSA to automate the audit of your social declarations in just a few minutes. More than a control tool, it is a true compliance shield: it operates upstream to detect and prevent anomalies, ensuring greater peace of mind for your teams and flawless declarations.
