You can now upload and store documents in Resly. You will now see a 'Files' tab in a reservation (to store copies of the signed registration card, ID etc). In a tenancy profile (to store a copy of the bond lodgement, tenancy agreements etc) and in an owners profile (to store their form 6, warranty receipts etc). 

Just click 'Add file', select the file from your computer, rename it and save.
