HI, you are welcome.
We support clients in develop reporting and forecasting and I can say you that everything depends by your expectation. Pipedrive allows you a quite good level of reporting and also (if properly planned) you can have reliable forecasts. But if you expect a BI tool, then you need some integration for that.
Feel free to have a trial in Pipedrive and if you need support we offer free of charge assessment and trial evaluation support.
As long as you do not try you will never know... (how good it is)
