Build vs. Buy SaaS Integrations: The Case for an Embedded Integration Platform
Blog post from Fastn
For B2B SaaS companies, the decision between building in-house integrations and adopting an embedded integration platform is crucial as it impacts long-term operational efficiency and cost. Initially, building custom integrations for popular platforms like Salesforce or Slack may seem attractive due to short-term customer satisfaction and controlled implementation. However, as the number of integrations increases, the maintenance burden, custom engineering requirements, and organizational costs can become overwhelming. An embedded integration platform allows customers to manage their own app connections and data flows within the SaaS product, reducing the engineering team's workload. AI-enhanced platforms, such as Fastn, further streamline this process by automating connector setup and maintenance. The decision to build or buy should consider the hidden and compounding costs of in-house development, which often become unsustainable as customer demands grow. For most SaaS companies, particularly at the Series A to C stages, adopting an embedded integration platform is more cost-effective and scalable in the long run.
