Overview

Available to clients with the Income module enabled, the API endpoints for BBSI (S17) and OI (S18) extracts can generate data in both a readable format for checking purposes and an unreadable format that meets HMRC’s specific submission requirements.

Generating the extract in an unreadable format will mark all transactions as processed, ensuring they are not included in extracts for subsequent years. As a result, any late payments will be captured in the extract produced the following year.
