iPaaS essentials: What it is, how it works, and why you need it

Modern businesses rely on technology in almost everything. Every activity, strategy, process, or communication is based on the use of a software solution or an application.

For example, you may use Salesforce CRM to manage customer relationships and boost sales, Microsoft Dynamics 365 for accounting, NetSuite for inventory and stock management, HubSpot for marketing, and Shopify for your online store.

But how do these systems talk to each other? How do you make them work together? That’s exactly what iPaaS (Integration Platform as a Service) is in charge of.

In this article we will analyze what iPaaS does, how it can make your business work smarter, types of integrations available, and much more.

What is iPaaS?

Let’s start with the definition. iPaaS is a cloud-based integration solution that enables the connection of various applications, data sources, and services in an organization. 

Simply put – iPaaS is like a central hub that connects all applications and systems and makes them work together in real time and share information without hiccups or delays. 

And when all systems understand each other and communicate effectively, your business processes run smoothly.

The value of iPaaS for businesses

Modern businesses tend to suffer from the same headache: how to manage multiple systems that weren’t originally designed to work together?

It’s a serious headache because without data integration your business tends to work in silos where each team doesn’t know what the other one is doing, which leads to miscommunications, delays and errors.

And in order to connect disparate systems and applications, you need to:

• understand the unique formats of how they generate and process data,
• transfer data from one to another, often manually, or
• hire IT specialists to build custom-coded integrations (and spend a lot of money).

Alternatively, you can cure this headache with iPaaS – a simpler and more efficient solution that enables frictionless communication between systems and makes data flow smoothly.

Practically speaking, an iPaaS solution provides pre-built connectors that enable an uninterrupted data flow between various systems such as ERP, CRM, HRMS, CMS, and many others.

The global iPaaS market is projected to grow from $12.87 billion in 2024 to $78.28 billion by 2032.

 

Types of integrations that iPaaS supports

iPaaS supports various types of integrations to connect diverse systems and processes. That’s why understanding (and distinguishing between) these types is crucial for selecting the right iPaaS solution for your business.

• Cloud-to-Cloud Integration – Connects two or more cloud-based applications to enable seamless data flow and automation.
  
  
  • Example: Syncing Salesforce CRM with  Microsoft Dynamics 365 Business Central to automatically transfer master data.
• Cloud-to-On-Premises Integration – Bridges cloud applications with legacy on-premise systems to ensure synchronized data and processes.
  
  
  • Example: Connecting Salesforce with an on-prem Microsoft Dynamics 365 Business Central to sync customer records.
• On-Premises-to-On-Premises Integration – Facilitates communication between two on-premise systems, often using middleware or hybrid iPaaS solutions.
  
  
  • Example: Integrating an on-prem  ERP with a local warehouse management system to streamline inventory updates.
• B2B (Business-to-Business) Integration – Enables secure data exchange between external business partners using APIs, EDI, or other standardized protocols.
  
  
  • Example: A retailer integrating with a supplier using EDI to automate order processing and inventory replenishment.
• Data Integration (ETL, ELT, Syncing, etc.) – Moves, transforms, and consolidates data across systems to ensure consistency and support analytics.
  
  
  • Example: Extracting sales data from multiple sources (e.g., Shopify, Stripe, and Salesforce) into a data warehouse for reporting.
• API-Led Integration (including API Management) – Uses APIs to connect applications, manage access, and enable real-time data sharing.
  
  
  • Example: A bank offers an Open Banking API that allows third-party financial apps to securely access customer account balances and transaction history.
• Event-Driven Integration – Triggers workflows and actions based on real-time events using webhooks or message queues.
  
  
  • Example: When an order is placed in Shopify, a webhook triggers an order fulfillment process in NetSuite.
• Process Automation / Orchestration – Automates end-to-end business workflows by integrating multiple applications and services.
  
  
  • Example: A marketing workflow where HubSpot leads are automatically assigned in Salesforce and an email campaign is triggered via Marketo.
• Industry-Specific Integrations (such as E-commerce, Healthcare, Finance, etc.) – Tailored integrations designed for specific industries to connect domain-specific applications and platforms.
  
  
  • Example: An e-commerce store integrating Shopify with FedEx to generate shipping labels and update tracking in real time.
    
    

Traditional Integration Methods vs. iPaaS

A practical example of iPaaS in action

Scenario: How iPaaS Transformed CRM, ERP, and Marketing Automation for a Growing Business.

The Challenge:

Trendwear, a fast-growing B2B services provider, relied on three key systems to manage customer relationships, operations, and marketing:

• Salesforce (CRM) – Used by the sales team to track leads, manage accounts, and close deals.
• Microsoft Dynamics 365 Business Central (ERP) – Handled inventory, order processing, and financials.
• HubSpot (Marketing Automation) – Managed email campaigns, lead nurturing, and customer engagement.

However, these systems were operating in silos, leading to:

• Slow lead-to-sale conversions – Marketing-generated leads in HubSpot weren’t automatically shared with sales in Salesforce.
• Manual order processing – Once a deal was closed in Salesforce, finance teams had to manually enter order details into Business Central.
• Fragmented customer data – Inconsistent data across systems led to duplicate records and inaccurate reporting.

REAL-LIFE EXAMPLE
A medium-sized clothing retailer used iPaaS to connect their online store, inventory management system, and shipping provider.

The result? 👉 Order processing time dropped from 2 hours to 10 minutes, and shipping errors decreased by 90%. Win-win! 🔥

To address these inefficiencies, the company did the following:

1. Choose an iPaaS solution. Opted for an iPaaS solution that offers pre-built connectors for specific CRM, ERP and marketing tools, because it will eliminate the need for extensive coding.
2. Created workflows. Using the iPaaS platform, they can design workflows that define how data should flow between the systems. For example, when a new customer is added in the CRM, their details get automatically updated in the ERP, which triggers a welcome email via the marketing tool.
3. Data synchronization. As data is entered or updated in any of the systems, iPaaS ensures that these changes are reflected across all platforms in real-time. As a result, the  sales teams have access to up-to-date information, finance can track orders on time, and marketing can target customers accurately.
4. Monitor and adjust. Now they can  monitor these integrations through the iPaaS dashboard, and make adjustments as needed to improve efficiency or add new functionalities.

And that’s exactly how iPaaS not only helps your company save time and reduce errors, but also improve team collaboration across departments and optimize business processes.

But there are even more benefits you can get from iPaaS! Let’s explore.
