yes all but 1 of my tenants have registered to their tenant portal but when I upload a new document which is shared with them they have no knowledge and I find once registered they never bother using it again we 1) we have no idea of when the tennat last logged in 2) they need to be automatically notified by email when a document is shared with them 3) if there was a tenant app they would be notified of a change or addition

this would be useful to see most /least profitable properties 

yes I agree, tenants soon lose the module web link. It would be better if they had an app which once downloaded would remain on their smart device

tenant app would be good tenants lose a webpage login 

I have tried to add a scanned total credit note and it will not allow me. Basically, I ordered something from screwfix which went through my bank ok with the scanned invoice. I cancelled the order and received a credit note and a refund into my bank. But I get the message "total price may not be a negative amount"
