Connect Comarch Optima and Izettle

Connecting Comarch Optima and Izettle for a company could make it possible to transfer sales data from point-of-sale transactions into the accounting and management system. This could support more accurate financial reporting, inventory updates, and simplify the reconciliation of sales with accounting records, reducing manual data entry and the risk of errors.

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

Why connect Comarch Optima and Izettle?

A company running both Comarch Optima and Izettle could benefit from connecting these systems to enable the exchange of data between financial management and point-of-sale operations. Without such a connection, staff may need to enter the same sales, inventory, or customer data into both systems, increasing the risk of errors and consuming valuable time. This manual duplication can lead to records drifting apart, where figures in one system no longer match the other, making it difficult to obtain an accurate, up-to-date view of business performance. Decisions could then be made based on incomplete or outdated information, impacting everything from stock control to financial reporting. If a connection were established, the types of data exchanged could include sales transactions, inventory updates, and customer details, as these are commonly handled by systems for retail management and accounting. The specific data that can be exchanged depends on what each system exposes 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 Comarch Optima and Izettle 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.
