Qonto Backup
Self-hosted CLI that exports your full Qonto business account to local disk every night: transactions, attachments, and PAdES probative receipts. Runs as a Docker container or Node binary on a Synology NAS.
Problem solved
Qonto stores your transactions and supporting documents on its servers. French law requires accounting records to be kept for 10 years (Code de commerce, art. L123-22). If you ever close your Qonto account, switch banks, or face a tax audit while their platform is down, accessing those archives gets complicated. The official manual export does not bundle attachments and skips the legally probative PAdES variant.
Value proposition
A nightly cron on your NAS that materializes your entire Qonto account locally, organized by year / month / day, with PAdES probative receipts alongside the original attachments. Setup takes 30 minutes. Re-runs are incremental and idempotent. You own your accounting data, independent of Qonto.
Target audience
Entrepreneurs, freelances, small business owners (TPE/PME) and accountants who want a local copy of their Qonto data, compliant with French long-term retention obligations. Tested on Synology DSM 7+ and Raspberry Pi.
Tech stack
- Node.js 22 (native fetch, native test runner, strip-types loader)
- TypeScript 5.7+ strict
- Zero runtime dependencies
- Multi-arch Docker image (
linux/amd64+linux/arm64) published on GHCR - GitHub Actions for CI, release-please for semver-driven releases
Status
Live and MIT-licensed. Code generated with Claude Code, then tested and reviewed manually. Open to issues and PRs. The codebase is intentionally small (~1000 lines) so it stays auditable.
