Recently we have integrated Dynamics 365 (or D365) with Leadfeeder. This has increased the efficiency of generating new quality leads and tracking the existing leads. The process is very simple and easy. After configuring Leadfeeder we had to just install the solution into the D365 instance. Then a simple authorization process, and that is all. By the way, a few custom fields needed to be created in the D365 Account entity, which is also explained very clearly in the integration guide. So this shows the extensibility or scalability, whatever you say, of D365 for the features we may need to meet our ever-growing and changing business needs. I find there are numerous such useful add-on solutions available for D365 in the market which is a very helpful aspect for D365 customers and users.
