Services that put
your company in order.

Full-Service Accounting

We keep your books always up to date, with rigor and precision, and deliver clear financial information so you can make business decisions with confidence.

Tax Advisory

Timely compliance with your obligations to the DIAN (Colombian tax authority) and the District Tax Office, with a strategic view that minimizes your tax burden within the law.

Payroll & HR

We run the full payroll cycle with controls at every step and full compliance with Colombian labor law. Your company approves and pays; we prepare, execute, control and document.

Occupational Health & Safety

Every employer in Colombia must have an Occupational Health and Safety Management System (SG-SST). We run it for you under the Plan-Do-Check-Act cycle, scaled to your company's size and risk level, with a dedicated OHS team and the documented evidence required by the ARL (occupational risk insurer) and the Ministry of Labor.

The employer remains legally responsible for the system and approves and signs it. A4S prepares, runs and documents it.

SENA, Enrollments & Employee Services

A dedicated team member handles the SENA apprentice quota, each employee's enrollments and terminations, and your team's requests, so nothing falls through the cracks between departments.

Payroll Implementation

A one-time project that leaves your payroll organized, configured and compliant from the first pay period. Duration depends on the size of your workforce; as a reference, about four weeks until the first payroll.

Statutory Audit

An independent statutory audit that provides reasonable assurance on your financial statements and legal compliance before Colombian oversight bodies.

Outsourced CFO

High-level strategic financial leadership without the cost of an in-house CFO. Ideal for startups that need expert financial leadership to scale.

Recruitment

We find the right finance and accounting profile for your company: professionals who understand the startup pace and integrate quickly into your team.
