Software Integration | Smart Integration of Business Systems

Working with multiple systems that don’t automatically share data costs your organization time, effort, and accuracy every day. The goal of integrating software is simple: make systems work together so data flows automatically, processes run smoothly, and employees can focus on what really matters. How you approach this determines whether it will still work three years from now.

When do you need a software integration?

You’ll notice it in small things. Employees manually transfer data from one system to another or export data to Excel just to import it elsewhere. A customer calls with a question, but the data in your CRM doesn’t match what’s in your ERP. Or an update from one vendor causes issues somewhere else. These are signs your systems aren’t properly connected.

Software integration solves this by enabling systems to communicate automatically. Data flows without human intervention: up-to-date, consistent, and in both directions.

How does software integration work?

There are several ways to connect systems. The most common are:
Direct API integration: Two systems are connected directly via an Application Programming Interface (API). Quick to set up and suitable for two systems with a clear data flow.
Integration platform (iPaaS): When dealing with multiple systems or more complex data flows, a central integration layer works better. All systems connect through one platform, making management easier and adding new integrations simpler.

At Product League, we use Alumio for this. A powerful iPaaS platform that keeps integrations manageable, even as your landscape grows. When we build digital applications ourselves, we set up integrations via OutSystems, making them part of the same low-code platform.

Which systems can you integrate?

Almost any business system can be integrated, from modern cloud solutions to older systems that don’t natively support integrations. In practice, we see most integration challenges in these areas:

ERP and finance: Connect your core system with your webshop, CRM, or HR software for a real-time data flow across your organization.

E-commerce and PIM: Automatically sync product data, inventory, and orders between your webshop and back office.
CRM and customer portals: Keep customer data consistent everywhere, without employees switching between systems.
HR and planning software: Automate the exchange of employee data between HR systems, scheduling tools, and payroll.
Legacy and custom systems: Even older systems without standard APIs can often be integrated. We always assess what’s technically possible first.

How we did it for PLUS Supermarkets

For PLUS Supermarkets, we built a future-proof webshop where integration wasn’t an afterthought; it was the core of the project. Three major platforms: OutSystems, Commercetools, and Contentful, work together as one system. Product data, inventory, and content flow automatically between systems, without manual input.

The result: a composable webshop that scales and evolves with the growth of PLUS. A technical setup that was realized in this way for the first time in the Netherlands.

Van koppeling naar beheersbaar integratielandschap

Een koppeling leggen is stap één. De uitdaging zit in wat daarna komt: systemen worden bijgewerkt, je organisatie groeit, er komen nieuwe tools bij. Als elke wijziging opnieuw maatwerk vereist, heb je over een jaar een nieuwe uitdaging. Daarom starten we altijd met een analyse van jouw huidige systemen, datastromen en groeiambities. Op basis daarvan kiezen we het juiste middel, of dat nu een directe integratie is of een centraal integratieplatform via Alumio. Daarna bouwen we stap voor stap, met inzicht in de voortgang en een heldere oplevering. En na livegang kijk je zelf of actief beheer door ons past bij jouw situatie.

What is the difference between a software connection and an integration?

A connection allows two systems to exchange data through a link, such as an API. With an integration, systems function as one, sharing logic and processes. In practice, the best approach depends on your systems and what you want to achieve. We help you make that choice based on your situation.

Can every system be integrated?

Almost every system can be connected, including older software without a modern API. The approach differs: a legacy system requires more preparation than two modern cloud applications. We always assess what is technically possible before proposing a solution.
