Connect katana and Izettle

Connecting Katana and Izettle for a company that uses both could enable the transfer of sales and inventory data between the two systems. This could support more accurate stock management, financial tracking, and streamlined order processing by ensuring relevant information is shared and updated across both platforms.

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

Why connect katana and Izettle?

A company operating both Katana and Izettle could benefit from connecting these systems to enable the exchange of key business data. Without such a connection, staff may need to enter the same information twice, increasing the risk of errors and inconsistencies. For example, sales or inventory figures in one system could diverge from those in the other, leading to confusion and decisions made on outdated or mismatched data. This situation can cause inefficiencies, as employees spend extra time reconciling records or correcting mistakes, and management may not have an accurate, up-to-date view of operations. If a connection were established, it could allow for the transfer of data such as sales transactions, inventory levels, or product details between Katana and Izettle. This could help keep both systems aligned, reduce manual work, and provide a more reliable basis for reporting and decision-making. The specific data that can be exchanged would depend on what each system makes available through its API and should be determined for each 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 katana 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.
