Integration Attach Rate

Integration attach rate is the percentage of eligible customer accounts using a particular integration or at least one integration alongside a core SaaS product. This metric shows how widely an integration is being used across the customer base, rather than whether customers have completed a specific activation event. The goal is to understand how many eligible customers are using a particular integration as part of their experience with the product.

Organizations typically measure integration attach rate by dividing the number of eligible customer accounts using an integration by the total number of eligible accounts. Teams can track the rate for individual integrations or for integrations as a whole, and compare it across customer segments, plans or use cases. This helps teams understand which integrations customers are using and where there may be opportunities to increase usage.

In B2B SaaS, integration attach rate helps product and partner teams understand how widely integrations are being used by customers. When tracked consistently, it can help inform integration priorities, partner recruitment and customer engagement. Because attach rate looks at the eligible customer base as a whole, it gives teams a broader view of integration usage than metrics that focus on whether a customer completed an individual activation event.
