Enterprise process automation on Python + LangChain

AI agents and integrations built in your own Python codebase. LangChain + LangGraph + FastAPI + Temporal — versioned, monitored, audit-ready agentic systems. Not a no-code platform: scalable, testable software. ROI typically 3-9 months.

Common use cases

What do we automate most often?

Six concrete use cases that pay back within 12 months for almost every client. Scroll through — the background follows the active card.

Invoice processing

Auto-recognition of incoming PDF / email / e-invoices, account coding, approval workflow, automatic payment instruction. Direct integration with Számlázz.hu, Billingo, KulcsSoft, QuickBooks, Xero. ROI: 1-3 months.

Lead routing & CRM sync

Web form to CRM (HubSpot, Pipedrive, Salesforce), AI lead scoring, automatic sales rep assignment, follow-up email sequence, Slack / Teams notifications. From cold lead to warm.

Cross-system data sync

E-commerce → ERP → accounting, or CRM → email marketing → support — any combination. Two-way or multi-way sync with error handling, idempotency and a retry policy. Built on Kafka or Temporal.

Document processing (OCR + AI)

Auto-recognition, classification and key-data extraction for contracts, reports, invoices, orders. Azure Document Intelligence / layoutLM + LLM-based understanding — not just OCR. Edge cases routed to human review.

Customer support automation

Inbound ticket classification, basic Q&A via a RAG-based chatbot, escalation to a human agent when needed. Typically 40-60% reduction in support volume measurable within 90 days.

Reporting & executive dashboards

Auto-aggregation of data (ERP, GA4, ad platforms, CRM), weekly / monthly executive reports, Power BI / Metabase / Looker dashboards. Leadership sees fresh numbers Monday morning.

Tools

Picking the right tool for the job

We do not favour one stack. We pick the tool that fits the task — often 2-3 tools in a single project.

LangChain + LangGraph
Our primary agentic stack. Multi-step, state-machine-modelled agent flows, tool calling, retrievers, memory management. All in code, tested and traced (LangSmith / Langfuse).
FastAPI + Pydantic
The automation layer's API. Structured input/output validation, CI/CD integrated, deployed on Docker / Kubernetes.
Temporal / Celery + Redis
Orchestration for long-running, retry-heavy flows. Idempotent tasks, exponential backoff, durable execution — built for enterprise.
OCR + Document AI
Azure Document Intelligence, layoutLM, Tesseract — structured extraction of invoices and contracts. Output validated by an LLM, edge cases routed to human review.
RPA — only where unavoidable
For legacy, API-less systems (SAP GUI, banking terminals). Once an API opens up, we replace it. RPA is a transitional solution, not a target.
Cloudflare Workers / Hetzner / AWS
Automation runs where it must — on the edge, in an EU-region cloud, or on-prem. Hungarian Tier IV data centre option for sensitive data.
Choosing

RPA vs. AI automation — when to use which?

RPA runs a robot on an existing screen; AI automation works at API level, with understanding. They are not adversaries — they complement each other.

Process automation — frequently asked questions

Process automation uses software to handle repetitive manual workflows automatically. Typical examples: incoming invoice processing, lead routing to CRM, data sync between systems, document classification, report generation. We build enterprise-grade, custom-coded systems: Python + LangChain + LangGraph agentic flows behind FastAPI, running on Temporal — versioned, monitored, observable. We do not sell no-code platforms; we deliver scalable, audit-ready software.
