Feature requested
MTD ITSA bridging service via CSV upload or API call (preferably the later).
Typical use case
For use by businesses or individuals with an existing accounting system that could be fairly easily extended to either output income tax data in a CSV file, or pushed to a QuickFile API endpoint.
How I would expect it to work
I would expect the QuickFile endpoint to offer similar functionality to the existing VAT bridging software service - in other words the data would consist of financial totals, not individual transactions.
