Connect Shopware and Izettle

Connecting Shopware and Izettle for a company using both systems could enable the transfer of sales and inventory data between the online store and the point-of-sale platform. This connection could support unified reporting, easier stock management, and more accurate financial reconciliation across both digital and in-person sales channels.

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

Why connect Shopware and Izettle?

A company that uses both Shopware and Izettle could benefit from connecting these systems to enable data exchange between their e-commerce and point-of-sale operations. Without such a connection, staff may need to enter the same sales, inventory, or customer data in both systems separately, which increases the risk of errors and consumes valuable time. This manual process can also lead to records in Shopware and Izettle drifting apart, so that product availability, sales figures, or customer information become inconsistent between platforms. As a result, decisions based on outdated or mismatched data could negatively affect inventory planning, financial reporting, and customer service. If a connection were established, it could allow the transfer of data such as product details, stock levels, sales transactions, and customer information between Shopware and Izettle. This could help keep both systems up to date and minimize the need for manual updates. However, the specific data that can be exchanged depends on what Shopware and Izettle make available through their respective APIs, and would need to be determined for each individual case.

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 Shopware 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.
