7. 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 tech­niques needs to be closed.
IaW is com­mit­ted to set up a sus­tain­able and donor-​independent dis­tri­b­u­tion chan­nel in which

• a choice of products
• at the right and hon­est price
• will 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.
