Wait for abit. The current farm plan is out dated and due an update, but there is going to be much better options really quite soon.These companies are suddenly pushing this type of product for a reason. They've worked out how valuable your data is. Nice for them if you can pay them to relieve you of it.
Just deciding between Farmplan and Xero for accounts at the moment. Have people with strong opinions on either side. One thing that I really object to was the data grab by Gatekeeper and for that reason I'm steering away from Farmplan.
