5. Building a Distribution Channel
Appropriate technology is only appropriate if people really are able to use it.
That means that the gap between innovations and possibilities for purchasing these

IaW is committed to set up a sustainable and donor-independent distribution channel

be offered with micro credits
This last benefit will make it possible for buyers to also build up credit history
that can benefit them at a later point. IaW will be the guarantor for its products
and therefore each product will be its own collateral. For the micro credit provider
it means access to a large group that has never been their customer and they might
be able to lower their interest rate.
IaW uses Alibre Design Professional
for our mechanical design and drawings and we would like to express thanks to Alibre
for their support and assistance with our work in Cambodia.
