We initially burnt hands doing custom development so stay away these days. 90% of our revenue comes from cloud hosting, which is opposite of OpenERP (which gets 90% of revenue via Partners). If we do custom development, product will suffer, so we are staying out. But we are happy to consider it if it really makes sense.

Will be happy to hear your views though (will send you a separate mail on this).

Yes, we don't do any custom development at Akvo either. Our revenue comes from hosting, training and implementation consulting services, but not technical implementation services, but implementing the tools themselves within the organisation.

We avoid technical implementation services, as most organisations we work with have a really low internal technical knowledge. If we then take the responsibility for implementing the technical side, we find that they don't take the ownership of the bigger issues. These are things like learning to publish open data and the changes in culture which this implies in the organisation. Then their failure to embrace the change needed in the organisation is projected as our failure to implement the technical side.

We have technical account management, but require for our partners who implement our tools to either have in-house the required technical skills or hire in the required skills. If they don't do this we don't do the projects, as they are very likely to fail.
