# Guerrilla engineering before Pablo’s temporarily leaves ## Scopes to cover - [x] FX rates available in SQL Server - Cosmos DB → DWH → Hyperline data flow for invoicing purposes - Hyperline → Billing DB → DWH data flow to maintain revenue reporting ## Decisions on 2024-16-12 - Ben R. takes care of raising a Postgres Server which we will call the “Billing DB”, which we use for all data exchange with Hyperline. - Data Team will push FX rates data into the billing db with Airbyte. - Data Team will push API line times into the billing db with Airbyte. - We would like for invoice and credit note data from Hyperline to be fed back into the billing db, but it’s unclear how we need to manage this.
