[Fictional Scenario] Julian, lead engineer at a fast-growing hardware startup in Bern, was pulling purchase bills via the Bexio REST API. Translating nested contact objects, QR-bill references, and IBAN structures into valid SIX pain.001.09 XML for the bank required writing brittle custom parsers.
Business Use Case & Requirements
Swiss companies integrating Bexio cloud ERP via REST API need a reliable transformer to turn JSON purchase bills and QR-bill references into compliant SIX pain.001.09 payment files.
Technical Architecture & Pipeline Execution
The translation engine ingests nested Bexio REST JSON payloads (`contact`, `qr_invoice`, `bank_account`), flattens and validates structured reference strings, and emits validated Swiss SIX-compliant pain.001.001.09 XML documents.

Standards & Compliance Highlights
- Swiss QR-bill reference numbers map directly into ISO 20022 creditor reference (SCOR) elements.
- pain.001.001.09 is the mandatory credit transfer standard for Swiss financial market infrastructure.
- Nested contact postal attributes ensure full compliance with strict Swiss address validation rules.
Industry Comparison & Perspective
While custom microservices or general ETL pipelines struggle with changing Bexio API schemas, this engine provides declarative JSON-to-XML mapping out of the box.
We appreciate Bexio for maintaining a well-documented REST API that lets Swiss developers build clean financial automation workflows.
