SaaS integrations are somewhat of a requirement within modern software and tech companies. Whether you are a small or large organisation starting to implement integrations can be a daunting process as there are a number of challenges thrown your way.
Common SaaS integration challenges include:
- API versioning
- Authentication complexity
- Data mapping
- Rate limiting
- Monitoring and maintenance
Plus SaaS integration is hard at scale.
Why is SaaS integration hard?
- The methods to implement SaaS integrations can be difficult and costly, especially the likes of ETL (Extract, Transform, Load). These methods can result in a loss of revenue and productivity due to the time and expertise needed to implement the ETL method.
- If the data transformation isn’t done correctly this can have a knock-on effect. For instance, data isn’t in the correct place at the right time for different teams, or data is siloed in different systems and not correctly communicating with each other.
- Performing data transformation takes time so it is important to expect this and account for it. Otherwise if done incorrectly it can result in lost revenue, productivity and morale. To ensure the process is done correctly thoroughly research, vet and understand the integration solution you are going to implement. Don’t just rely on one method and be open to the process happening in stages rather than all at once.
- Security is always a challenge, especially when trying to keep company data secure. SaaS integrations must be able to implement multi-layered security controls and maintaining security levels if the organisation is switching from on-premise to cloud-based as part of their digital transformation strategy.
- Authentication protocol needs to be implemented and ensure secure integration processes are agreed upon prior to implementation. In doing this there will be finer control on access, data will be encrypted and meet the latest security protocols.
- A lack of knowledge can really hinder the SaaS integration process due to the lack of skilled staff to develop and maintain integrations. Integrating with multiple SaaS vendors helps expand an organisation’s digital environment, it can however get complicated quickly.
Ways to Minimise these Challenges
To help implement SaaS integration and minimise the challenges you can:
- Understand your integration needs and how they can help your digital strategy
- Research integration methods and vendors to figure out what is best for your organisation, then thoroughly vet them
- Scope and estimate the time scale of the project but be flexible
- Plan and factor in contingencies to follow
- Get everyone on the same page and update teams and inform them about the requirements
- Keep track of your progress
The challenges of SaaS integration shouldn’t be underestimated, but organisations shouldn’t be deterred by them. By finding the right method and integration provider organisations can set themselves up for integration success seamlessly. They’ll be able to navigate the integration landscape and expand their product to improve their competitive advantage and their strengths.
Types of SaaS Integration Approaches
| Integration Type | Dev Effort | Time to Market | Maintenance Cost | Scalability |
| Native Integrations | Low (pre-built by platform) | Fast | Low | Moderate (limited to built-in connectors) |
| Custom API Integrations | High (build from scratch) | Slow | High | High (flexible, but requires careful design) |
| iPaaS Solutions | Moderate (configure vs. code) | Moderate | Moderate | High (supports multiple systems & scaling) |
| Embedded iPaaS | Moderate (integration SDK + config) | Fast | Low to Moderate (platform handles updates) | High (scalable across customer environments) |
| Unified APIs | Low to Moderate (single API interface) | Fast | Low | Moderate to High (depends on provider capabilities) |
Other methods becoming more widely used are IaaS (Integration as a Service), iPaaS (integration Platform as a Service) and embedded iPaaS. These are external integration providers that help you build and deploy your own SaaS integrations for your organisation, or enhance your product for your customers to use.
