The regulatory infrastructure for digital commerce.
From checkout to tax filing – fully automated, auditable and ViDA-ready. Not software. Not a tool. An operating system for compliance.
Traditional accounting systems and simple tax tools are not designed for the demands of digital commerce. They rely on batch processing instead of real-time processing – and on file systems instead of relational database technology.
Fragmented Systems
Platform data, payments, accounting and tax filings run in separate systems. Reconciliation is manual and error-prone.
Delayed Truth
Accounting reality lags behind operational reality. ViDA, however, demands transaction-level accuracy – not month-end corrections.
Growing Liability
Directors and tax advisors bear personal liability. Without integrated infrastructure, risk increases with every marketplace and every border.
SyncLine is built on IBM Informix – a high-performance relational database
While traditional accounting systems rely on file systems or lightweight databases, SyncLine is built on IBM Informix with true transactional integrity, replication and near real-time processing. This is the technological reason why SyncLine handles millions of records per client in dialogue processing rather than batch processing – creating the prerequisite for ViDA compliance.
Not software, not an add-on, not an e-invoicing tool. An operational infrastructure layer between digital platforms, business transactions and regulatory requirements.
SyncLine is
- Regulatory infrastructure (Regulatory Operating System)
- Fully automated real-time transaction processing
- GoBD-compliant with audit-proof archiving (10 years)
- Monitored by employed chartered accountants
- 30 years of proven technology – in production, not announced
SyncLine is not
- Not a traditional accounting software
- Not a partial VAT tool
- Not a manually operated add-on
- Not a development promise – in production for decades
- Not a replacement for your tax advisor
Five stages – fully automated. From data capture to finished report.
eCommerce Merchants
Platform sellers on Amazon, eBay and own shops. Especially for cross-border trade with OSS/IOSS requirements.
Tax Advisors & Firms
Operational relief. Recurring revenue per client. No IT investment required. Annual accounts remain entirely with the firm.
Third-Country Sellers
Merchants from Asia and other non-EU countries selling via EU platforms. No tax IT in Europe required. Fully multilingual interface and document output – including CJK character sets.
SyncLine is specialised in eCommerce requirements but is equally suited for businesses without online trade thanks to its comprehensive financial management architecture.
SyncLine provides operational relief without displacing existing revenue models. It delivers the groundwork – not the tax decision.
3–6 hours → 0–1 hour
Monthly time per eCommerce client drops drastically through fully automated pre-processing.
Reduced Liability
Source-based data, complete audit trail and SOP-driven processing lower error rates.
Recurring Revenue
Ongoing share per connected client. No additional operational effort or staffing required.
No IT Investment
GoBD-compliant data export, DATEV-compatible import (optional). No changes to existing firm IT required.

30+ Years
Proven technology foundation
SyncLine already meets 90% of ViDA requirements. The remaining items (DRR, additional platforms) can be added with the existing architecture.
OSS / IOSS incl. threshold logic
Fully integrated. Automatic threshold checks and country-specific VAT determination.
E-Invoicing + XML processing
Structured e-invoices already today. Format update to EN 16931 / UBL 2.1 prepared.
Real-time processing
No batch processing. All transactions are processed immediately – a fundamental prerequisite for ViDA.
Platform rules (Amazon, eBay)
Detection and separation: genuine merchant vs. platform seller. Platform-specific tax logic implemented.
ELSTER, EC Sales List, Intrastat
Automated filings to German and EU authorities. Fully integrated.
VAT ID + EORI verification
Automated online verification. Part of the standard solution for years.
SyncLine does not address an optional software market but a regulatory-driven infrastructure market, triggered by the EU initiative VAT in the Digital Age (ViDA).
The planned spin-off into a German SE (European public company) serves to focus on scaling, distribution and capital market readiness.
The technology is in production. The regulatory demand is structural. The business model scales through process architecture – not through headcount.
