SaaS Integration: How do you do it?

Updated on 2nd March 2026 by Hayley Brown

Integrating your SaaS product with a range of other cloud applications isn’t just a technical checkbox, it’s a strategic differentiator. In today’s digital ecosystem, customers expect their tools to talk to each other seamlessly, unlocking automated workflows, richer insights, and more efficient business processes. Yet building and maintaining a suite of reliable integrations in-house can quickly drain engineering resources, slow your product roadmap, and create ongoing support headaches.

Building in-house SaaS integrations is 1) time-consuming 2) expensive and 3) complex.

Below is a table indicating how the SaaS market has grown, the average number of SaaS apps companies use, and what integration/maintenance costs look like drawn from recent industry data.

Metric	Typical Value/Range
Global SaaS market (2025 est.)	$300 B+
SaaS market annual growth (CAGR)	18.7 % to 20 %+
Average SaaS apps per company	106 apps
Large enterprise SaaS apps	125–200+ apps
Integration maintenance share of SaaS spend	20 – 35 %
Custom API integration annual cost	$50,000 – $150,000+

This highlights just how connected SaaS ecosystems are, making them more complex and heavy on engineering resources. This is where a modern integration strategy, especially one powered by an embedded integration platform like an iPaaS transforms the game. Rather than stretching your team thin trying to connect APIs one by one, you can accelerate development, reduce complexity, and deliver the connected experience your users demand.

We’ll walk through what multi‑SaaS integration really involves, the common challenges teams face, and how the right approach helps you scale faster while keeping your product competitive and customer‑focused.

Integrate with multiple third-party SaaS technologies 

Third-party integrations add necessary external data to an existing project using different APIs. This means features and tools can be added quickly rather than in months if developed in-house. Helping businesses respond to the market faster. 

Integrations and integration capability are becoming an industry-standard in modern software and if you don’t have it the more likely you’ll fall behind the pack. DZone notes, “integrating with SaaS applications means providing your organisation with consistent, responsive, and secure access to services, applications, and platforms.”  

With the ability to integrate with multiple third-party applications you open up your product to a potentially huge client base, increase brand value and improve customer experience.

Build complex data workflows that combine and process multiple data sets

API integration platforms are designed to remove the complexity of integrating and make the process quick and easy. This is because the tool allows users to design, build and post integrations for their customers directly within their application. 

For example, a data workflow could be a simple data set such as syncing customer contacts from an email marketing platform to a CRM. On the other hand, they could be somewhat more complex, combining and processing multiple data sets across numerous SaaS applications. For instance, generating invoices based on financial customer data (orders or subscriptions) then triggering an email application to notify customers and finally updating the CRM.

The embedded iPaaS becomes an invisible layer within your SaaS but provides all the integration capabilities you need to develop a wider partner ecosystem. 

Accelerate time to market with new solutions and improve product competitiveness

A huge benefit of embedded iPaaS systems is that they save organisations time. Not only are builds quicker and native, but any customer requests can also be dealt with by numerous members of a team due to low code functionality. 

Before, when businesses built in-house integrations it meant piling more work onto development teams. The development team want to focus on developing the core product, and as a result, an integration backlog forms. Not only do embedded iPaaS platforms reduce this they help organisations upskill existing employees rather than fork out for more expensive developers. 

By empowering and upskilling employees to tackle integration requests an organisation’s time to market with solutions is quicker. Resulting in a sticker product and making it much more competitive.
