Connect Adyen and Accelo

Connecting Adyen and Accelo for a company could enable automated transfer of payment data from Adyen into Accelo’s project management or billing modules. This integration could help reduce manual entry, improve accuracy in invoicing, and support more timely financial tracking within the company’s operational workflows.

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

Why connect Adyen and Accelo?

A company operating both Adyen and Accelo could benefit from connecting these systems to enable more efficient and accurate data exchange. Without a connection, staff may need to enter the same information in both systems, which increases the risk of errors, inconsistencies, and delays. For example, payment or transaction data processed in Adyen could be manually re-entered into Accelo for billing, project management, or client record-keeping. This manual process can lead to records drifting apart over time, making it difficult to reconcile financial figures or gain a real-time view of business performance. Decisions might then be made based on outdated or incomplete data, undermining operational effectiveness. If these systems were connected, the types of data that could be exchanged include payment transactions, client details, invoice statuses, and possibly project billing information. Timely synchronization of such information could support better reporting and reduce administrative workload. However, what can actually be exchanged depends on what each system exposes through its API, and is determined per 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 Adyen and Accelo 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.
