Connect SAP ECC-R/3 and Square

Connecting SAP ECC-R/3 and Square for a company could enable the transfer of financial or sales data between enterprise resource planning and point-of-sale functions. This could support more accurate accounting, centralized reporting, and improved inventory management by reducing manual data entry and helping ensure data consistency across both platforms.

You can build this integration on the System2System platform. We design the connection between SAP ECC-R/3 and Square around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect SAP ECC-R/3 and Square?

A company running both SAP ECC-R/3 and Square could benefit from connecting these systems to allow for data exchange between core business operations and point-of-sale activities. By enabling the systems to share information, the company could reduce the need for manual data entry, which is often time-consuming and prone to errors. Without such a connection, there is a risk that records in each system would diverge, leading to inconsistent customer, inventory, or financial data. This could result in business decisions being made based on outdated or inaccurate information, impacting operational efficiency and customer satisfaction. If a connection were established, it could allow for the exchange of data such as sales transactions, inventory levels, customer records, and financial postings. For example, sales data captured in Square could update relevant accounts and stock levels in SAP ECC-R/3, while master data managed in SAP ECC-R/3 could be made available to Square for accurate transaction processing. The specific types of data exchanged would be determined by what each system can make available via its API, and this would be defined according to the company’s operational needs and technical possibilities in each 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 SAP ECC-R/3 and Square 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.
