Your company has a nasty habit to sell products that are not ready. This is a shame because you got great ideas and products we want to use! But you are also in a field where peoples are serious about their content that can represent years of works.

Crashing, slow import, strange behavior, are not an option. Every feature has to works.

You should provide your alpha product for free until they are ready. If you need cash flow presale at a lower price. But let your customer know it's not ready yet!
