Connect AFAS and Aca

Connecting AFAS and Aca for a company could allow the transfer of relevant data between the two systems, such as employee, financial, or administrative information, depending on each system’s capabilities. This could support more efficient workflows and reduce manual data entry, provided the integration is designed to respect both systems’ data structures and security requirements.

You can build this integration on the System2System platform. We design the connection between AFAS and Aca around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect AFAS and Aca?

A company that operates both AFAS and Aca could benefit from connecting these systems to enable data exchange and reduce inefficiencies. When systems are not connected, staff may need to enter the same information into both platforms, which increases the risk of errors and consumes valuable time. Over time, this can result in records that no longer match, leading to confusion, redundant work, and business decisions based on outdated or inconsistent data. By establishing a connection, the company could reduce manual data entry and help ensure that information such as employee details, financial transactions, or project records is consistent across both systems. Data that is commonly exchanged between systems of these types may include contacts, invoices, payroll information, or project management data, provided these are core functions of the systems involved. The specific data that can be exchanged depends on what each system makes available through its API and must be determined for each individual situation.

How System2System builds an integration

Connectors

We connect to each system through the interface it offers — an API, a database, a file exchange or a webhook — and handle authentication, rate limits and retries.

Mapping

Fields rarely line up one to one. We map and transform the data so both systems receive it in the shape they expect.

Workflow

We define what triggers an exchange, in which direction data flows and which system takes precedence when the two disagree.

Monitoring

Every exchange is logged. Failures are flagged and can be replayed, so nothing disappears without anyone noticing.

What can actually be exchanged?

That depends on what AFAS and Aca make available through their APIs, on the licences and modules in use, and on the version each system runs. Which records are synchronised, in which direction and how often, is something we determine together before any work starts.

We are happy to look at your specific situation and tell you what is feasible — including when the answer is that it is not.
