⚠ The problem
You waste hours searching for documents—and thousands of euros on lost contracts.
✕Receiptsare scattered across email inboxes, NAS drives, and desks.
✕Contractsare printed, signed, scanned, and emailed back.
✕Duringthe GoBD audit, PDFs are suddenly missing, version statuses are unclear, and retention periods are being violated.
✕ExternalDMS tools cost extra, require a separate login, and don't have access to your customers, orders, and documents.
✓ The solution
CATAMA DMS — one module, one login, all documents.
✓Versioned & audited: every change is logged with a hash and timestamp.
✓Full-text OCR search across all PDFs, images, and scans—even in old documents.
✓Digital signature via email link with hash chain — legally binding, without third-party providers.
✓Retention policies, legal holds, and automatic deletion — GDPR and GoBD compliant.
✓Directly linked to CATAMA customers, orders, and invoices — no data silos.

Live Tour
This is what the DMS looks like in action.
A quick tour of the main screens—from the document list to the signature request.
01 · Dashboard
At-a-glance overview.
Storage utilization, OCR status, pending signature requests, documents under legal hold—all key metrics on a single page, with clickable drill-downs into each section.

02 · Full-text search
It really finds every document.
After uploading, OCR runs automatically in the background—even on handwritten notes, photo receipts, and older scans. The search function supports operators, filters (folders, tags, date range, owner), and result highlighting in the snippet.
✓Multi-stageOCR (local → cloud fallback)
✓Filterby folder, tag, time period, status
✓Auto-suggestions& saved searches

Each step is chained using SHA-256 — proven to be tamper-proof.
Security & Compliance
Legally sound. GDPR-compliant. Traceable.
From the very beginning, the DMS was developed with audits, compliance, and hosting in Germany in mind. No external U.S. providers, no data sharing, no black box.

FAQ
Frequently Asked Questions
Is the digital signature legally valid in Germany?▾
Yes. The DMS uses an SHA-256-linked audit chain (each step references the hash of the previous one), hash anchoring of the PDF before and after signing, and unique IP and user-agent logging. This means it meets the requirements for an advanced electronic signature (AES) under eIDAS Article 26—suitable for contracts, maintenance agreements, data protection consents, and similar business documents. For qualified electronic signatures (QES, e.g., notarized documents), we offer a D-Trust/Bundesdruckerei connection as an add-on upon request.
Where is the data stored?▾
By default, it is hosted on the same server as your existing CATAMA installation—in other words, where all your customer data is already stored. Optionally, you can switch to S3-compatible storage (e.g., Wasabi DE) or a Hetzner Storage Box (WebDAV). No data is transferred to U.S. providers.
Do we need new hardware?▾
No. The DMS runs on the existing CATAMA environment. We recommend Tesseract (or a cloud fallback) only for the OCR function, and ClamAV as an optional virus scanner. We install both as part of the onboarding process.
What happens to our data if we cancel?▾
At any time, with just the click of a button, you can receive a complete ZIP export archive of all original files, including metadata in JSON format and an audit trail as a signed CSV file. No lock-in.
Why shouldn't we use an external DMS?▾
External tools (DocuSign, DATEV DMS, M-Files, etc.) are excellent—but they don’t know your customers, orders, or invoices. You’d have to create each document twice or sync it via an interface. In CATAMA DMS, every document is automatically linked to the order, customer, appointment, or set of tires you’re currently working on. Experience shows that this saves a small-to-medium-sized business 10–15 hours per month in duplicate data entry.
Ready to retire your filing cabinet?
We’ll set up your DMS on your CATAMA instance in under 2 hours and train your team—all included in the onboarding package at no extra cost.
