System integration is defined as integrating existing, often disparate systems in order to improve performance. Data is transferred and transformed, uninterrupted, through the business process. Effectively the multiple disparate systems act as one co-ordinated system. This reduces operational costs and improves response times, with the overall IT infrastructure providing more value to the company.

Introduction to system integration

If you’re reading this page you have probably found or been introduced to the term ‘system integration’ and want to find out more. Congratulations – you’re in the right place. Perhaps you’re intrigued about what it can do, or you have identified disparate systems or applications that need to connect. Either way, here you will learn about system integration. You’ll find out how it can be achieved using different solutions and how they  focus on different aspects. Of course, if you don’t find the answer you’re looking for you can always ask us. To make sure you’re not wasting your time, let’s start by defining system integration. Then you know the following information will be of use.

What is system integration?

System integration technology connects disparate systems. This allows businesses to connect SaaS, cloud and on-premise applications, then integrate information through the business process. Essentially, data is transferred and transformed, uninterrupted, through a business process with the separate applications acting as one co-ordinated system.

There are multiple ways this is achieved, including the use of APIs (application programming interface). An API is the part of the application’s code that dictates how the sending and receiving of information takes place. By making it available, other applications can connect into it. The API allows the business to deliver data to the system, whereupon data transformation can translate it into a format and structure the target system can recognise and ingest.

EDI – or electronic data interchange – is another common form of integration. It is a computer-to-computer exchange of business documents. This exchange is based on a standard electronic format which allows business partners to interact.

Online retail is a great example of system integration. By integrating ordering, stock management and distribution systems, goods can be dispatched almost immediately. This opens up opportunities for great, customer-focused services like next day delivery or same day collection in store.

There are many benefits to system integration:

  • The flow of data is unified through all applications.
  • There are fewer manual data entry points, so the information stays clean and accurate (human intervention increases the risk of errors).
  • Less time is spent on manual processing, allowing the business to operate more efficiently.
  • The organisation has a complete picture of all interactions, so they can deliver an informed and personalised customer service.
  • SLA monitoring is improved.
  • Stringent security controls ensure compliance requirements are met and customers can be confident they are doing business with an organisation that protects their data.

System integration solutions

There are technologies that focus solely on integrating other systems. Yet more and more of the applications themselves are being designed to connect with other new or legacy systems. Most of the time businesses find this addresses their integration requirements. Take Managed File Transfer, for example. MFT solutions deliver sophisticated integration capabilities, allowing businesses to move data securely, input it into its next end point effectively, and implement the follow on process efficiently.

Who uses system integration?

These case studies are just some examples of how different industries have leveraged the power of system integration.

Wholesale, food and beverages

Using EDI to integrate ordering, stock management and distribution systems, goods can be dispatched almost immediately

A study by GS1 – who developed the most widely used supply chain standards – found that the grocery retail sector saves £650 million per year in costs by using EDI instead of manual, paper-based processes for its orders, invoices and despatch advices. Speed is the main benefit, with research citing a reduction in the processing time from 3-5 days, to a few minutes. Other benefits include: more accurate data, improved process efficiencies, cost savings and elimination of paper-based processing.

Other sectors leveraging the benefits of EDI include: Pubs, catering businesses, clothing retail, DIY, healthcare and public administration.

Public Sector

A local council used Managed File Transfer to move information to third-parties when it couldn’t securely connect via existing government gateways. Files were sensitive, such as reports concerning a member of the public, or a contractual negotiation with a supplier.

The solution was used by anyone wishing to send information to the council. Similar to a self-addressed envelope, a council employee could simply send an empty package to the third party, in which they place their documentation before pushing it back securely.

Robotic process Automation in the public sector


Insurance regulators often request reports or audits with very little notice. Robotic Process Automation (RPA) integrates with the relevant applications, like Crystal Reports, the Infinity system and Microsoft Great Plains. RPA pulls the data, generates reports and provides regulators with the information they request simply and quickly. This faster, more accurate report creation saves multiple employees days of work per month.

RPA is also used to automate the closing out of each month’s claims, which saves IT staff a lot of time on what was previously a long, manual process.

Online Retail

By integrating ordering, stock management and distribution systems, the goods can be dispatched almost immediately. This opens up opportunities for great, customer-focused services like next day delivery or same day collection in store.

Data with fewer manual re-entry points will be more accurate, as human error is reduced. Costs associated with paper, printing, storage, postage and document retrieval are reduced. Goods and services can be delivered faster, which ultimately translates to growth and profit.

NHS and the healthcare industry

A medical company wanted to eliminate their reliance on a significant number of file integration protocols, which were owned by their former parent company. Rather than duplicate the existing complicated systems they installed Managed File Transfer to simplify and manage their automated and manual data transfers, whilst providing greater control and a more secure, reliable flow of data. This was particularly important for financial information such as invoices, orders and Bankers’ Automated Clearing Services (BACs) files. Managed File Transfer reduced their reliance on multiple solutions.
