A custom ERP is a business management system built to mirror your exact operational workflows rather than forcing your team to adapt to predefined software logic. Off-the-shelf platforms like SAP or Odoo cover common business functions but require extensive customization, often costing more than a purpose-built solution, when your processes deviate from the standard template.

Panorama Consulting Group reports that 53% of ERP implementations exceed their original budget, primarily due to customization costs on off-the-shelf platforms. A custom ERP eliminates this risk by building only the features your business actually uses.

There are no unused modules consuming screen space. No features your team must learn but never opens. The user interface matches your existing terminology, reducing training time to days rather than weeks.

For businesses with unique logistics chains, regulatory requirements, or multi-entity structures, custom ERP delivers lower total cost of ownership over a 5-year horizon than licensed alternatives.

Modular ERP architecture is a development approach where each business function, inventory, finance, HR, reporting, is built as an independent module that connects to a shared data layer. This allows phased deployment: your team starts using completed modules immediately while remaining modules are still in development.

We digitize operations in priority order:

• Inventory: Real-time stock tracking with automatic reorder triggers, warehouse location mapping, and barcode/QR scanning integration
• Finance: Automated invoicing, expense tracking, bank reconciliation, and FINA e-invoicing compliance for Croatian businesses
• HR: Digital employee records, leave management, document storage, and payroll data export
• Reporting: Custom dashboards pulling real-time data from all modules into a single executive view

Each module is independently testable and deployable. Your team validates real data in staging before anything touches production. This reduces go-live risk and delivers value incrementally rather than in a single high-stakes launch.

ERP interoperability is the ability of your central business system to exchange data automatically with external services, banks, government portals, logistics providers, and third-party software. Without these connections, staff manually re-enter data between systems, introducing errors and consuming hours of administrative time weekly.

We build bidirectional API connections that turn your ERP into a master hub:

• Banking: Automatic payment reconciliation with major EU banks via PSD2-compliant APIs
• Government compliance: Direct submission to FINA for fiscal reporting, VAT forms, and OIB validation
• Logistics: Instant shipping label generation for DHL, DPD, GLS, and Croatian Post directly from the order screen
• CRM sync: Bidirectional data flow with HubSpot, Salesforce, or Pipedrive so sales and operations share a single source of truth

A mid-sized distribution company eliminated 22 hours per week of manual data entry after we connected their custom ERP to their bank feed, logistics provider, and accounting system. Error rates on invoice processing dropped from 4.2% to under 0.3%.

Data sovereignty in ERP means your business data is stored, processed, and accessed exclusively within infrastructure you control, with full compliance to GDPR and the right to choose between cloud and on-premise deployment. For EU businesses handling employee records, financial data, and customer information, this is a regulatory obligation under GDPR Articles 25, 32, and 44.

We implement enterprise-grade security at every layer:

• Encryption: AES-256 at rest, TLS 1.3 in transit
• Access control: Role-based permissions (RBAC) ensuring each user sees only the data relevant to their function
• Audit logging: Every data access, modification, and export is logged with timestamp and user identity
• Backup strategy: Automated daily backups with point-in-time recovery capability

You choose the deployment model: EU cloud hosting (AWS eu-central, Hetzner) for accessibility and automatic scaling, or on-premise for maximum control. Both options maintain full GDPR compliance.

The code and data belong to you. No vendor lock-in, no license keys, no access restrictions.

ERP implementation is a strategic business decision that affects every department, and the relationship with your development partner must extend well beyond the initial launch. Companies that treat ERP as a one-time project find themselves needing a rebuild within 3–5 years as business requirements evolve. Companies that maintain an ongoing engineering partnership adapt their system continuously.

We begin every ERP project with structured business discovery workshops (remote or on-site) to map your processes, data flows, and decision points before writing a single line of code. The output is a functional specification your entire team reviews and approves.

Post-launch, monthly retainer agreements cover module expansion, performance optimization, new integration development, and security patching. Your ERP grows with your headcount, your revenue, and your operational complexity.

Most of our ERP clients remain with us for 3+ years, not because of contractual lock-in, but because an engineering team that understands your business logic delivers changes in days rather than the weeks a new team would require.

A structured ERP implementation follows a phased approach that eliminates the two most common causes of failure: unclear requirements and insufficient testing. Panorama Consulting reports that 50% of ERP projects experience operational disruption at go-live. Our five-phase process reduces that risk to near zero through systematic validation at every stage.

Phase 1. Business Discovery (1–2 weeks): We document your current processes, data flows, and pain points in a structured workshop. Output: a functional specification your entire team signs off on before we write a line of code.

Phase 2. Modular Build (4–12 weeks depending on scope): We build module by module, inventory first, then finance, then HR, then reporting. Each module is independently testable. Your team validates real data in staging before anything touches production.

Phase 3. User Acceptance Testing (1–2 weeks): Your team tests every flow with real business scenarios. We fix, iterate, and document. No guesswork at launch.

Phase 4. Go-Live and Hypercare (2–4 weeks): We remain on standby during business hours for immediate fixes. Most go-lives have zero critical incidents when the prior phases are respected.

Phase 5. Ongoing Support: Monthly retainer options cover updates, new module development, and performance monitoring. Your ERP grows with your business, without forcing a full rebuild every two years.

Custom ERP, SAP Business One, and Odoo serve different business profiles. Custom development delivers 100% process fit with zero license fees. SAP provides enterprise-grade depth at enterprise-grade cost. Odoo offers modular flexibility but requires customization for non-standard workflows.
