Payroll

KAERUS structures every aspect of your payroll setup in detail.

This includes configuring companies and establishments and integrating the applicable collective agreement.

We manage registrations with the relevant organisations, including URSSAF, pension funds, provident schemes and supplementary health insurers.

We also handle DPAE pre-employment declarations and mandatory registers, as well as the operational implementation of PAYE income tax withholding.

The entire framework is configured and reviewed in advance to ensure payroll compliance from the very first payslip, while limiting the risk of errors and disputes.

Human resources

KAERUS manages the entire process throughout each payroll period.

We collect and verify payroll variables before producing and reviewing payslips.

We also prepare payroll cost reports and provide the information required to process payments, before securely submitting all statutory social declarations.

Continuous monitoring of collective agreements and regulatory developments ensures that minimum rates, contribution rates and applicable rules remain up to date.

Each change is analysed and incorporated into the following payroll cycle to maintain compliance over time.

Our approach

Every engagement begins with a detailed payroll and HR review covering the existing setup, registrations, applicable collective agreement and employment contract templates.

This assessment identifies any necessary corrections, structures HR workflows and establishes a clear payroll and social compliance calendar.

We carry out consistency checks at every stage and complete the process with an analytical review at the end of each cycle.

An operational summary highlights key areas requiring attention and any adjustments to be made during the following period.

Our tools

A dedicated employer portal centralises all exchanges and provides access to a digital vault for the secure archiving of payslips.

Social declarations are submitted electronically, while electronic signatures simplify approval processes.

The collaborative workspace allows payroll variables to be uploaded, processing progress to be monitored and the complete history of the file to be consulted.

Professional Ethics and Confidentiality

Payroll and HR files are fully documented. Our quality management system is based on formalised internal controls, continuous monitoring of employment and social regulations, and regular backups.

Payroll and HR data is processed in accordance with the General Data Protection Regulation (GDPR), using infrastructure hosted within the European Union. Access rights are role-based, and sensitive operations are logged.

In accordance with the professional standards of the French Order of Chartered Accountants, we guarantee the independence of our analyses, professional secrecy, the prevention of conflicts of interest and the confidentiality of information.

Our engagements are covered by professional liability insurance.
