Read this page as one judge. Each weighs the same scores by what they care about.

The IT Integrator

Weighted verdict

Connects the DMS to the ERP, DATEV and Microsoft 365 and maintains it afterwards. Wants connectors with a stated scope rather than a logo wall, a documented API with webhooks, single sign-on, and a migration path in and out that does not depend on the vendor's services team.

Same scores as the panel view — this lens weights them the way this judge cares.

Capture, OCR & indexing

How this is scored

How documents get in and become findable: scanning and email intake, OCR, classification and metadata extraction, and whether incoming e-invoices (XRechnung, ZUGFeRD) are read as structured data rather than as pictures.

0 — Manual upload only; no OCR, no metadata beyond file name and folder.

3 — Upload, drag-and-drop and scan import with OCR mentioned, but indexing is manual and no word on email intake or e-invoice formats.

5 — Scanner, email and folder intake, full-text OCR, document types with metadata fields, and automatic extraction of common fields (date, sender, amount) documented.

8 — AI- or rule-based classification and field extraction with confidence and a validation step, XRechnung and ZUGFeRD read as structured data, mailbox and Microsoft 365 intake, and duplicate detection documented.

10 — Capture is engineered and shown: classification and extraction trainable per document type, validation queues, e-invoice validation against the standard, intake channels listed with their limits, and where AI processing runs (location, model provider) stated.

Report an error

The IT Integrator

Capture is the deepest documented area: batch scanning at over 800 images a minute with more than 200 supported scanners, deep-learning OCR and AI classification with extraction down to complete item tables, and XRechnung, ZUGFeRD, Factur-X and FatturaPA processed as structured data with EN 16931 syntax checks, plus e-mail and portal intake. It stops short of the top because we found no public information on validation queues with confidence values, duplicate detection, or where the AI and the LLM assistant lumee actually do their processing. 3 4 7

Report an error

Versioning, permissions & audit trail

How this is scored

Who may see and change which document, what happened to it, and whether earlier states can be recovered: version history, check-in and check-out, role- and attribute-based rights, and an audit trail of reads and changes.

0 — Files overwrite each other; rights only at folder level or not described; no log of who did what.

3 — Version history and folder permissions exist, but no check-out, no record-level rights and no documented audit log.

5 — Version history with restore, check-in and check-out, roles and groups with document-type or record-level rights, and an audit log of changes documented.

8 — Metadata-driven permissions (by department, client or confidentiality), audit trail covering reads, exports and deletions, single sign-on and directory sync (Entra ID, LDAP) documented, and administrators' own actions logged.

10 — Access is provable: the audit trail is tamper-evident and exportable, permission changes are themselves versioned, field-level rights and need-to-know access for HR or legal records documented, and the log retention period stated.

Report an error

The IT Integrator

Version management and a granular, configurable access and permission system are named, and archived documents are described as tamper-proof with every access traceable — but that traceability is a single sentence with nothing on export or retention of the log. We found no public information on check-in and check-out, restoring earlier versions, or single sign-on and directory sync, which is exactly what I need before wiring this into Entra ID. 5 9 1

Report an error

Audit-proof archiving & retention

How this is scored

GoBD-compliant, revisionssicher archiving: immutability of archived documents, retention schedules and deletion, tax-audit data access, and the independent evidence behind the claim — scored on what is certified and documented, not on the word "GoBD-konform".

0 — No statement on archiving, retention or GoBD.

3 — "GoBD-konform" or "revisionssicher" claimed with no certificate, no description of how immutability is achieved and no retention settings documented.

5 — Archived documents documented as unchangeable, retention periods configurable per document type, deletion after expiry, and a sample Verfahrensdokumentation or GoBD guidance offered.

8 — An auditor's report (IDW PS 880 or comparable) published or named with its scope and date, WORM or equivalent storage described, legal hold, GDPR deletion reconciled with retention duties, and Z1–Z3 tax-audit export documented.

10 — Archiving is evidenced end to end: current Testat with scope covering the cloud and on-premises editions as sold, retention and deletion logged and reportable, long-term formats (PDF/A) enforced, and a documented procedure for the tax audit and for moving the archive without breaking its integrity.

Report an error

The IT Integrator

Immutability is described in the vendor's own words — documents are stored tamper-proof and cannot be changed afterwards — and retention is backed by central deadline management, cloud-archive retention management, and an info sheet plus webcasts on revision-safe archiving and GoBD. We found no public information on an auditor's report such as IDW PS 880, WORM storage, legal hold, deletion after expiry, or a Z1–Z3 tax-audit export. 5 6 7

Report an error

Document workflows & integrations

How this is scored

What happens to a document after it arrives: approval and invoice workflows, tasks and deadlines, and the connectors that tie the DMS to ERP, accounting, DATEV, Microsoft 365 and the rest of the stack.

0 — No workflows; documents are stored and nothing else.

3 — A fixed approval or sharing step and a handful of named integrations, with no workflow designer and no API documentation.

5 — A workflow designer for approvals and invoice processing, tasks with deadlines and substitutes, Microsoft 365 or Outlook integration, and a documented REST API.

8 — Graphical workflow modelling without code, invoice workflow with ERP or DATEV handover documented, connectors for named ERP systems (SAP, Microsoft Dynamics, DATEV) with their scope, webhooks or events, and e-signature integration.

10 — Workflows are a platform: versioned workflow definitions, process reporting with throughput times, a public API reference with rate limits and a sandbox, a partner marketplace of integrations with stated maintainers, and workflow history kept in the audit trail.

Report an error

The IT Integrator

Invoice workflows with automatic distribution, plausibility checks and comparison against ERP or financial accounting data are well documented, with substitution rules, deadlines, an invoice inbox, SAP, Microsoft Dynamics 365 and DATEV named, and a true REST API behind a gateway with authentication alongside integrated e-signatures. What holds it back for me is that the connectors read as a logo list without stated scope, and we found no public information on webhooks or events, a public API reference with rate limits and a sandbox, or a graphical workflow designer. 7 8 1

Report an error

Search, retrieval & exit

How this is scored

Finding documents again and taking them with you: full-text and metadata search, saved searches and mobile access, and whether documents, metadata, versions and audit trail can be exported in documented formats when the contract ends.

0 — Folder browsing only; no export beyond downloading single files.

3 — Full-text search exists, but no metadata filters, and bulk export is undocumented or only on request.

5 — Full-text and metadata search with filters and saved searches, mobile or web access, and bulk export of documents with their metadata (for example CSV or XML) documented.

8 — Search across versions and attachments with permissions respected, export of documents in original format with metadata, versions and audit trail in a documented structure, and an import path from other DMS or file shares named.

10 — The exit is designed in: a documented complete export with schema, export available self-service at any time, the post-termination retrieval window and data deletion stated, and archives stored in open formats so a successor system can take them over intact.

Report an error

The IT Integrator

Search itself is strong: index and full-text search with faceting, multi-criteria filtering, scoped folders and registers, semantic and associative options, text found even in charts and graphics, and mobile access via app or browser. The exit is where the evidence runs out — export is documented only as a one-click paginated PDF file with a table of contents, and we found no public information on bulk export of documents with their metadata, versions or audit trail, nor an import path from another DMS or file share. 9 10 1

European sovereignty

How this is scored

Who the contracting entity and its owner are, where documents and their metadata are stored and processed in the cloud edition, and who the subprocessors are — including any AI provider that reads document content. Independently sourced by the sovereignty pipeline.

0 — Non-EU contracting entity, no statement on where documents are stored, and subprocessors unnamed.

3 — An EU entity contracts, but the cloud edition runs on a non-EU-controlled hyperscaler without a stated safeguard, or the subprocessor list is absent.

5 — EU contracting entity and EU data centres stated for the cloud edition, with a DPA, but significant parts of the chain (hosting, AI processing, support) are non-EU-controlled without a stated safeguard.

8 — EU entity, documents and metadata stored in named EU data centres, subprocessor list with locations published, AI processing location disclosed, an on-premises or private-cloud option offered, and certifications (ISO 27001, BSI C5) published.

10 — Sovereign end to end and evidenced: European ownership, EU entity, every processing location and subprocessor European, customer-controlled keys or on-premises operation available, and certifications with their scope published.

Report an error

The IT Integrator

Provenance places OPTIMAL SYSTEMS in Berlin with development in Germany, an on-premises edition is offered, and ISO 27001 is claimed. The captured pages give no statement on where the cloud edition stores documents and metadata, no subprocessor list, and no word on where the LLM assistant lumee or the classify-pro SaaS services process content, and the contracting entity's jurisdiction is flagged as not confirmed on the vendor's own pages. 1 4 1

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the cost of a given number of users, storage and modules — including cloud versus on-premises licensing, maintenance, implementation partner fees and price increases — from public pages alone.

0 — No public prices at all; every quote comes from sales or a partner.

3 — A "from" price or a single edition priced, but modules, storage, maintenance and partner implementation are unstated — the real cost is unknowable.

5 — Editions priced per user or per month, but at least one commonly needed cost (storage, archiving or workflow module, maintenance percentage, onboarding) is missing or "on request".

8 — Every edition and module priced publicly, storage limits and overage stated, on-premises licence and maintenance terms given, and contract term and notice period published.

10 — Complete cost computability: a configurator or price list covering users, modules, storage and deployment model, partner implementation priced or bounded, and price-increase terms on a public page.

Report an error

The IT Integrator

We found no public information on pricing: no per-user or per-edition figure, nothing for a portfolio advertised at more than 100 solutions, no storage, maintenance or contract terms, and contact runs through a mandatory contact form. For a buyer, the real cost is computable only by talking to sales. 4 1
