we would like to support the iodé development financially beyond from purchasing devices (we are just a very small company). I know about the possibility for donations, but this does not work well for companies.
Other projects offer a “business support” or “business edition” or similar for this purpuses. The main point is to have something to get an invoice for and have VAT handled correctly.
Nevertheless I think it would be a good idea to offer a “sponsoring product” in your shop. I could imagine, that more companies would like to support iodé. Sometimes it is not feasable to buy a phone from you.
