Why custom ERP

Why custom ERP instead of SAP, Dynamics, or NetSuite?

Off-the-shelf ERP looks cheaper on day 1. Not on year 5. Escaping the licence trap is easier now than later.

Custom ERP - no SAP licence trap

SAP, Microsoft Dynamics, Oracle cost €130–€500/user/month. A custom ERP is paid for once, then it's yours - no recurring licence. For a 50-person company, the break-even is usually within year one.

Built around your processes

Off-the-shelf ERPs (SAP, Dynamics, NetSuite) enforce 'standard' processes - your company has to adapt to them. A custom ERP works the other way: the system adapts to your processes, not the reverse.

Modern web-based, mobile-friendly

Not a 2010-era Windows client - a modern browser-based UI (Astro / Next.js / React). Works from any device (laptop, tablet, phone) with offline capability and automatic sync.

Connects to everything

Webshops (Shopify, WooCommerce), accounting software, CRMs (HubSpot, Pipedrive, Salesforce), B2B portals, banking APIs, custom REST / GraphQL / SOAP integrations. Anything with an API can talk to your ERP.

Localised for your jurisdiction

For Hungarian operations: NAV Online Számla 3.0, HUF VAT categories, EU OSS settlement, EKAER, Hungarian POS integration. For other EU markets: country-specific tax rules, e-invoicing, and reporting baked in.

70% lower 5-year TCO

For a 30-person company, SAP Business One / MS Dynamics 365 runs ~€130–€210k over 5 years (licence + implementation + maintenance). A custom ERP: €40–€80k upfront, ~€8–€15k/year maintenance. 5-year total: ~€80k vs €210k.

FAQ

Custom ERP development - Frequently Asked Questions

How much does custom ERP development cost in 2026?

Starting at €20,000 for a 1-2 module MVP (sales + invoicing, ~10 users). Mid-complexity ERP with 5-7 modules (sales, inventory, finance, HR, projects): €40–€80k. Enterprise ERP with manufacturing, MES integration, BI: €80–€260k. Yearly maintenance is 15-25% of the base cost (new features, regulatory updates, security). 5-year TCO for 30-person company is ~€80k, vs SAP Business One at ~€130–€210k.

How long does custom ERP development take?

A 1-2 module MVP: 3-5 months. Mid-complexity 5-7 module system: 6-12 months. Enterprise system with manufacturing and integrations: 12-24 months. We work in 2-week agile sprints - usable prototype from month 2. Go-live is typically rolled out module by module to avoid downtime.

What is an ERP system and why do I need one?

An ERP (Enterprise Resource Planning) system is software that manages all your business processes in one place: sales, inventory, procurement, manufacturing, finance, HR, projects. Without ERP, companies typically run 5-15 separate tools (Excel, accounting, warehouse, CRM, etc.) - data is duplicated, errors compound, and reporting takes days. A well-designed ERP keeps all data in one place in real time - leadership sees the company's actual state instantly.

What's the difference between custom ERP and SAP / Microsoft Dynamics?

SAP / MS Dynamics / Oracle / NetSuite are off-the-shelf systems with predefined processes that your company must conform to. Licence costs €130–€500/user/month (5 years, 30 users = ~€130–€260k). Custom ERP is built around your processes, no monthly licence fees, source code is yours - no vendor lock-in. The trade-off: longer initial development (6-12 months vs 2-4 months implementation). For 30-300-person companies, custom typically wins on TCO.

Can you integrate with our existing systems?

Yes. Typical integrations: accounting software, payroll systems, e-commerce platforms (Shopify, WooCommerce, Magento, BigCommerce), CRMs (HubSpot, Pipedrive, Salesforce, Zoho), banking APIs, e-invoicing systems (NAV in Hungary, KSeF in Poland, SAF-T elsewhere), MES, PLCs. Integrations via REST / GraphQL / SOAP / EDI / SFTP. A typical integration runs €600–€2,500; complex MES or banking can reach €3–€10k.

Where does the ERP run - on-premise or cloud?

Both options are available. Cloud (Cloudflare, AWS, Hetzner, EU data centers): lower entry cost, automatic scaling, we handle ops (€130–€800/month). On-premise (your server): full data sovereignty, one-time infra cost (€8–€26k), your IT team operates it. Hybrid is also common - sensitive data on-prem, public-facing UI in cloud.

What if we want our in-house team to take over later?

No vendor lock-in. Full source code is yours (Git repo) plus documentation (architecture, deploy, ops guides). We onboard your team and hand over infra credentials. Optional part-time mentor / support contract during transition. We use mainstream tech (Next.js, PostgreSQL, TypeScript) - easy to hire for.

Can you build an ERP for a manufacturing company (MES, production)?

Yes. Manufacturing ERP / MES is one of the most complex projects - BOM management, production orders, capacity planning, machine data acquisition (Modbus, OPC UA, MQTT), shop floor terminals, barcode/RFID, OEE/KPI monitoring, traceability. Typical manufacturing ERP project: 12-24 months, €80–€210k. We have experience in automotive, FMCG, and precision manufacturing.

AI capabilities

How AI fits into this solution

What AI can do, how to integrate it, what to comply with - and how to keep your data on-prem.

● What AI can do here

Invoice and document processing

Extract incoming invoices, delivery notes, and POs from PDF/email with OCR + LLM. NAV-online integration, automatic GL coding suggestions.
Inventory and demand forecasting

Predictive model trained on historical data for weekly/monthly demand. Procurement suggestions based on lead time and minimum stock.
Financial anomaly detection

Unusual transactions, duplicate invoices, wrong tariff codes flagged automatically - with human-in-the-loop approval.
Internal ERP assistant (chat)

Natural-language access to your ERP knowledge: "How many open orders do we have for partner X?" - RAG over your own ERP data.

● How we integrate it

RAG over ERP data

Vector database (Qdrant / pgvector) built on ERP records. The model only answers from your own data - no external hallucination.
Function calling

AI agent calls ERP APIs directly - create order, generate report, look up partner. Every call audited and bound to permissions.
Inbound document pipeline

Email / SFTP / folder watcher → OCR (Tesseract / Azure DI) → LLM extraction → ERP API. Failed cases routed to human review.

Compliance

GDPR

Personal data is processed only on a documented legal basis. Data minimisation, purpose limitation, and audit trail enforced by design.
EU AI Act

Risk-based classification of every AI use case (minimal / limited / high risk). Mandatory transparency, human oversight, and CE-style conformity for high-risk systems.
NIS2

In essential and important sectors AI must follow security-by-design: access control, logging, incident reporting, supply-chain risk for any model provider.
ISO 27001 / SOC 2

When required: ISO 27001 / SOC 2-aligned controls, including key management, RBAC, audit, vulnerability management.

Local / on-prem deployment

Ollama / llama.cpp

Open-weight models (Llama 3.x, Mistral, Qwen, Gemma) running on your own GPU server or even CPU. Zero data sent to third parties.
vLLM / TGI

Production-grade inference servers for self-hosted endpoints. Concurrent users, streaming, function calling supported.
Sovereign cloud

For organisations without on-prem GPU: deployment on EU / Hungarian sovereign cloud (e.g. dedicated tenant), with data residency contracts.
Hybrid

Sensitive content always local; for non-sensitive batch tasks frontier models (Claude, GPT) via DPA-backed API where allowed.

Data security model

No training on your data

Whether self-hosted or vendor API, we contractually exclude your data from any training set.
PII redaction before prompt

Automatic PII detection and masking before any prompt leaves your perimeter - pseudonymisation as a hard rule.
Per-role access

Every AI surface uses your existing IAM (Entra ID / Keycloak / Okta) - the AI only sees what the user is allowed to see.
Full audit

Every prompt, response, and tool call logged with user, time, and source - replayable on demand.

How it connects

How does the ERP fit into the rest of the stack?

An ERP is never an island - every serious rollout ships with integrations and adjacent systems.

A custom CRM ties customers, deals, and history into the ERP - one data flow from lead to invoice. On the warehouse side, a WMS warehouse system keeps stock and put-aways in real-time sync.

For manufacturers, a MES / SCADA system is wired in alongside the ERP so the shop floor data flows up. The integration plumbing is delivered as a system integration project - ERP ↔ CRM ↔ shop ↔ banking via a custom Python integration layer.

Repetitive admin (invoice processing, approval flows, document extraction) is replaced by process automation on Python + LangChain. When the ERP is part of a wider digital transformation, the roadmap is sequenced together.
