We are now in active searching of stock management app which will fully integrate with our business model, your app meets almost all of our requirements, I've few questions regarding features, can you kindly specify if its possible in app now, or maybe its available to quote us for this customization:

1) Can we disable the shop module for a while and use only stock manager, before we don't use it and activate it later when we will need it?
2) Can we manage multiple file uploads in attachments? I checked out the demo and as I see there is option to upload only 1 file, it's very important for us.
3) There is an option to add Supplier Part Number, custom fields and couple other fields in "Product info", but I can't search in Product list by the info from that field, is it possible to enable searching by that fields?
4) Can we slightly modify the "PDF Invoice" template and translate it to our local language?
5) Also can we translate the admin panel?

Looking forward to get your reply,
Thank you!
