Once the application is lodged, you deal with the lender directly. Conditions, approval and settlement all run through the lender, not through Financeable.
In Financeable
The application stays in your Applications list. Archive it when you're finished with it - see Manage an application
Some fields lock once it's submitted - see Manage an application
If the customer comes back for another deal, clone the application rather than starting again
If the lender needs more
Supply it to the lender directly, through their portal or your contact there. Keep a copy on the application too, so the deal's paperwork stays in one place - see Upload supporting documents.
