Wrong figures get filed and look fine until the accountant queries them; spot-check ten each month. Every supplier invoice and fuel receipt lands in one searchable archive, OCR'd and tagged, ready for your accountant — self-hosted, software cost zero. ### The problem It's the 4th of the month. Your accountant wants Q2 expenses. Half your supplier invoices are PDF attachments buried in email, a quarter are paper receipts in a drawer, and the rest are screenshots on your phone. You spend an evening forwarding, scanning, and renaming files — and you'll do the exact same thing next quarter. For a 3–15 person business this is typically 2–5 hours a month of pure drag, plus the ones you lose, which cost real deductible expenses. ### The architecture [ Email inbox (invoices@) ] ──┐ [ Phone scan app ] ───────────┤──▶ [ paperless-ngx consume folder / mail rule ] [ Desktop scanner ] ──────────┘              │                                            ▼             [ OCR layer (OCRmyPDF, built in) → searchable PDF/A ]                                            ▼             [ Auto-tagging (built-in classifier learns from your corrections) ]                                            ▼             [ Searchable archive ] ──▶ [ monthly export → accountant / bookkeeping import ] One machine, one Docker Compose file. paperless-ngx watches a mail account and a folder; everything dropped in comes out OCR'd, dated, tagged by supplier and document type, and full-text searchable. Your accountant gets a filtered export instead of a shoebox. ### Tool choices — and why paperless-ngx (GPL-3.0, 40.7k stars, release April 2026). The core. Chosen because it bundles the whole intake chain — mail consumer, OCR, classifier, archive, API — in one actively maintained package with a large community. The built-in classifier is not an LLM: it learns from your manual corrections, which is exactly right for a stable set of 20–50 recurring suppliers. Alternatives like building your own OCR pipeline mean owning table extraction, retries, and monitoring yourself — a net negative for a small team. OCRmyPDF (MPL-2.0, 34.1k stars, release April 2026). The OCR engine paperless-ngx uses under the hood (Tesseract-based). Listed separately because it's also useful standalone for batch back-OCR of your existing PDF archive before migration. Optional LLM extraction — Ollama (MIT, 175k stars, release June 2026). If you later want line-item extraction (amounts, VAT, invoice numbers as structured data), run a small local model via Ollama against paperless-ngx's API. Start without it; the searchable archive alone kills most of the pain. A note on vetting: the popular paperless-ai companion project failed our checks — its README carries an explicit "not maintained" notice and the last release is roughly 8 months old — so we don't recommend it, whatever the star count says. Monthly cost. Software: €0, all self-hosted open source. Hardware: €0 if you have any spare mini-PC or NAS that runs Docker; otherwise a small European VPS runs roughly €4–8/month (verify current pricing — it moves). Your time: expect a half day for setup and a couple of weeks of casually correcting tags while the classifier learns. Compare: commercial document-intake SaaS for this typically starts around €15–50/month per user. ### Setup outline 1. Create a dedicated mail address (invoices@yourdomain) and tell suppliers to use it. This one habit does half the work. 2. Deploy paperless-ngx with the official Docker Compose file on your box or VPS. 3. Configure the mail rule: consume attachments from invoices@, delete-after-import off until you trust it. 4. Set up a consume folder synced from your phone's scan app (any app that saves PDF to a synced folder works). 5. Define document types (invoice, receipt, contract) and correspondents for your top suppliers; correct tags for two weeks so the classifier learns. 6. Monthly: filter by tag and date range, export, hand to accountant — or import the CSV of metadata into your bookkeeping tool. ### Pitfalls — the real ones Don't expose it to the internet. The paperless-ngx team says it plainly: documents are stored unencrypted, so run it on your LAN or behind a VPN, never on an open port. Your invoices are exactly the data an attacker wants. Backups are not optional. This becomes your system of record within a month. Snapshot the data volume off-machine, and test a restore once. OCR is not bookkeeping. Tesseract-class OCR reads clean print well and handwriting badly. Treat extracted totals as search aids, not accounting truth — the human posting entries still checks the figure. EU note: structured e-invoicing (Peppol and national mandates, already mandatory in Belgium for B2B since January 2026) will progressively shrink the PDF-invoice problem. This pipeline stays useful for receipts, foreign suppliers, and the long tail — but don't over-invest in extraction sophistication the regulation will make redundant. ### Verified repos [paperless-ngx](https://github.com/paperless-ngx/paperless-ngx) — GPL-3.0, 40.7k stars, active (April 2026) [OCRmyPDF](https://github.com/ocrmypdf/OCRmyPDF) — MPL-2.0, 34.1k stars, active (April 2026) [Ollama](https://github.com/ollama/ollama) — MIT, 175k stars, active (June 2026) Get the next blueprint as it publishes — free, practical, verified tooling only.
