Data Sovereignty

On-premise & Air-gapped — data is in the hands of the business

The entire solution is built entirely on the company's infrastructure (On-premise) and can operate with an independent storage system (Air-gapped). This is the optimal model to ensure data sovereignty, privacy and eliminate dependence on third-party Cloud providers thanks to 100% autonomy from hardware to software.

The real problem

SME is wasting software budget

Most small and medium-sized businesses pay for 4–6 separate pieces of software that don't connect to each other — while still lacking a unified system.

💸

Royalty costs per capita

Microsoft 365 or Google Workspace charge per-user per month. 20 employees = 20 times costs. After 3 years, you have paid enough to buy a separate system.

🔧

Discrete tools, distributed data

CRM in one place, accounting in one place, HR in one place. Each department has different software, data is not synchronized, reports must be compiled manually every hour.

🔒

Vendor dependent, loss of data control

SaaS software can increase prices, change features, or close at any time. Your data lives on their servers — you don't really own it.

Core Features

Everything your business needs in one platform

NAD ERP provides an entire ecosystem of administrative tools, with seamless integration — no need to buy additional addons or connect through third parties.
