What we do
One partner, from blueprint to production.
Whether you need a system built from the ground up or an open-source platform shaped to fit, our team owns the outcome end to end.
Custom ERP Development
ERP systems modeled on how your teams actually operate — not the other way around.
Open-Source Customization
We extend platforms like Odoo, ERPNext, and Frappe with modules built for your workflows.
Integrations & APIs
Connect ERP, CRM, e-commerce, and finance tools into one dependable data flow.
Support & Maintenance
Monitoring, upgrades, and a real team on call once your system goes live.
Why Hiltz
We speak both languages: enterprise process, and open-source code.
Most vendors either build everything custom at enormous cost, or bolt on rigid off-the-shelf software you have to work around. We do neither — we start from proven open foundations and engineer exactly the parts that make your business different.
Faster to launch
Built on hardened open-source cores, not from zero.
No vendor lock-in
You own the code, the data, and the roadmap.
Fits your process
Custom modules mapped to your real workflows.
Senior engineers only
A dedicated team that stays through go-live and beyond.
