Route4Green is an API service. Your system stays the source of data and the place decisions are issued. Route4Green does the route computation.

Declare vehicles and vehicle plans, then push orders and drop points. If you already run a TMS, this is usually a background sync job.
Create a job with your constraints: delivery windows, payload, maximum stops per run. Jobs run asynchronously because the problem is large.
Poll the job, or register a webhook and get called back when it finishes. The result gives you stop order per vehicle plus the plan metrics.
It depends on how clean your order data already is. For a system that holds normalised drop points with coordinates, the API work is a few days. The longer part is usually address normalisation and reconciling the vehicle list. We say this up front because it is the step most often underestimated.
