The CFO cockpit
Full control over total volume (€), mathematical verification rate, and conflict status at a glance.
The Proof
Mathematically verifiable results instead of statistical estimation.
Doc-Forge uses SMT solving from chip verification to verify the consistency of your financial data within explicitly defined rules — not just assume it.
AI estimates. Doc‑Forge verifies.

Product Tour
The platform in action
Experience mathematical certainty and automated excellence inside an intuitive enterprise interface.
Mathematical verification (Z3)
Real-time constraint checks: the SMT solver proves every calculation (VAT, totals, discounts) down to the fourth decimal place.
Collaboration & multi-user
Secure teamwork through soft locking, GoBD-compliant audit trails, and integrated comment workflows with @mentions.
No-code workflow assistant
Automate complex processes. Z3 instantly validates whether your custom rules remain logically contradiction-free.
Native integrations
Infinite scalability: enable native connections to DATEV, SharePoint, Slack, Teams, or Excel with one click.
Audit-safe export
Generate DATEV EXTF and SEPA PAIN.001 files. The Z3 safety gate guarantee: no export without mathematical proof.
Logic Validation
While other systems hope the AI is right, Doc-Forge checks the logic.
Our deterministic core detects inconsistencies within the rule model in milliseconds — and explains the root cause with mathematically consistent alternatives.
Net × 0.19 = VAT | Net + VAT = Gross
Inconsistency detectedINVALID
Netto / Net€ 4,200.00
MwSt. / VAT€ 714.00
Brutto / Gross€ 4,914.00
VAT was calculated at 17% — inconsistent with rule model (19%).

SMT layer identifies the inconsistency and shows the mathematically consistent variant.
Enterprise Pillars
Solid architecture for security, auditability, and enterprise integration.
Data Sovereignty
Local processing with a shielded data path, controlled access boundaries, and a clearly defined system perimeter. Your financial data remains under your control, audit-friendly for internal review, and governance-ready for external requirements.
Mathematical Audit
GoBD-grade assurance through formal verification, deterministic rule paths, and mathematically reconstructable outcomes. No guessing, only defensible proofs for every decision, exception, and export.
Infinite Scalability
An action library for SAP, DATEV, Slack, and more. Doc-Forge plugs into existing operations instead of replacing them.

*0% errors within the modelled rule framework — based on defined test cases within the current rule model.
Statistical accuracy in accounting is not a feature, it’s a system flaw. We didn’t invent SMT solving, but we’re the first to have the guts to use it relentlessly against the chaos of traditional OCR systems.
Under the Hood
Open for Audit. Built for Security.
Enterprise buyers do not purchase a black box. Doc-Forge exposes rule logic, constraints, and verification steps in a readable, audit-friendly way. Verification is based on explicitly defined rules and does not replace professional review outside this model.
* for deterministically modeled rules
RuleEngine / SMT
rule vat_consistency(invoice) {
let vat = round(invoice.net_amount * 0.19, 2);
assert invoice.vat_amount == vat;
assert invoice.gross_amount == invoice.net_amount + vat;
assert invoice.currency == "EUR";
}Example rule. In practice, multiple tax rates, rounding strategies, and line-item totals are evaluated.
Security-First Architecture
A serious security posture for sensitive finance operations.
Safe by Mathematics
Founder-Security-Policy
Integrated duress-mode support for emergency scenarios, including controlled location-data routing.
Privacy by Design
The Z3 logic runs locally. Sensitive financial data is never used to train public models.
Audit-Ready
Every RuleEngine decision is deterministic and can be mathematically reconstructed years later.

The New Global Standard. Exclusive, or Open.
Wir haben die Architektur für den ersten mathematisch beweisbaren Finanz-Standard fertiggestellt. Derzeit evaluieren wir, ob wir dieses Protokoll als exklusives Asset an einen globalen Marktführer übergeben oder durch die 'Open Core Initiative' den gesamten Markt demokratisieren. Die Entscheidung fällt in Q3 2026.
We have completed the architecture for the first mathematically provable finance standard. We are currently evaluating whether to hand over this protocol as an exclusive asset to a global market leader or to democratize the entire market through the 'Open Core Initiative'. The decision will be made in Q3 2026.
