ERP Development in Berlin for D2C E-Commerce, Manufacturing, Professional Services and Startups

ERP development in Berlin addresses Germany's rigorous financial compliance requirements where GoBD mandates Verfahrensdokumentation describing all business-relevant processes, records with traceable corrections preventing undetected alterations and complete audit trails, and Datenzugriff ensuring tax-relevant data is accessible in machine-readable format during tax audits. DATEV integration with SKR03 or SKR04 Kontenrahmen is essential for working with German tax advisors (Steuerberater). ZUGFeRD and XRechnung electronic invoicing following EN 16931 serves both public sector (ERechV) and increasingly private sector requirements. Berlin's D2C e-commerce brands need multichannel management across Shopify, Amazon.de, Zalando and other platforms with German returns handling. Manufacturing companies need Warenwirtschaft with Stuecklisten, Fertigungsauftraege and Kalkulation. DSGVO (German name for GDPR) is directly applicable with BDSG and TDDDG providing actual supplementary scope for terminal access purposes and necessary exceptions. ZTABS delivers ERP development in Berlin, remote-first by design with an office in Houston, Texas.

Our web development services and enterprise software services complement Berlin ERP development.

Enterprise system	$300K to $500K	8 to 14 months

The vendor comparison benchmark is at business platform scope: multi-department, SSO with SAML or OIDC, workflow engine, ERP and HRIS integration, audit logging, and applicable SOC 2 or HIPAA readiness preparation where buyer requirements warrant. SOC 2 Type 1 assesses controls as of a specific date; Type 2 covers a defined observation period. Benchmark assumes 2026 US buyer scope and pricing.

DSGVO, BDSG, DORA and regulatory considerations

DSGVO/GDPR directly applicable in Germany. BDSG provides supplementary provisions. TDDDG actual supplementary scope for terminal access purpose and necessary exceptions. UWG Section 7(3) actual sale own-similar electronic advertising conditions.

When ZTABS is not the right fit

• Staff augmentation filling ongoing ERP seats is outside this build engagement. Augmentation is scoped separately with its own responsible personnel.
• You need licensed Steuerberater or Wirtschaftspruefer advisory. We build systems; tax and audit require licensed firms.
• Dedicated on-site staffing is separately contracted with agreed scope and responsible personnel.
• Ongoing ERP administration or managed hosting is outside this implementation engagement. Administration and hosting are scoped as separate retainers.

Risks in Berlin ERP development

E-invoicing transition. B2B e-invoicing requirements with phased dates. ERP must be configurable for applicable formats before mandatory dates.

Giropay ended 31 December 2024. Payment integrations must reflect current German payment landscape. Actual Klarna consolidated Sofort route. SAP, DATEV licence, tenant and migration records permissions require verification.
