On-Premise ERP Software: Offline ERP on Your Factory Server
On-premise ERP software runs on a server inside your own factory, and users connect to it over the local network: your data never leaves the building, and an internet outage does not stop daily work. Data, the manufacturing ERP from P-Soft (Barsavash Fanavaran), is offered only this way: installed on the factory’s own server and used from a web browser on any PC or tablet.
This page is for manufacturers that have already decided, or nearly decided, where their data should live and now want to know what an offline ERP looks like in practice: what the factory needs to provide, what happens on a day without internet, how a support engineer reaches the server without creating a security worry, and what each Data plan adds. If you are still weighing the two models, start with our cloud vs on-premise ERP comparison; this page picks up where that article ends.
What Does On-Premise ERP Mean for a Factory?
In the on-premise model, the software and its data sit on hardware the factory owns, kept in a server room or next to the company’s network equipment. Users do not install a program to work with Data; they open a browser and type the system’s address on the internal network. That is why a shop-floor operator on a tablet, a storekeeper on the old warehouse PC and the finance manager on a laptop all reach the same shared information.
The key difference from internet-based services is the path each request takes. A user’s click never leaves the factory walls; it travels to a server a few meters away. Day-to-day reliability therefore depends far more on the quality of your internal network than on the state of the internet connection in your city or industrial park.
Why Factories Look for an Offline ERP That Works Without Internet
The reasons vary from plant to plant, but one of these four is usually behind the decision:
- Unreliable internet: some industrial areas simply do not have a stable connection. If the core system depends on the internet, every outage pushes receipts, issue slips and production stage reports back onto paper, to be keyed in again later.
- Confidential drawings and costs: drawings entrusted by customers, the cost of each part and the supplier list are competitive assets, and many managers prefer to keep them on their own hardware only.
- Customer requirements or internal policy: some industrial customers ask their suppliers not to store project information outside the company network, and some companies set that rule for themselves.
- Predictability: when the shop floor does not depend on an outside service, the daily schedule cannot be derailed by an event you do not control.
What Data Keeps on Your Own Server
The whole chain of work in the factory lives in one system on that same internal server; nothing is kept separately somewhere else:
- Sales: every inquiry and its path to approval, each customer’s file with past orders, and parts that are ready for delivery.
- Engineering and production: the bill of materials and material cost of each part, the sequence of operations, the production plan, stage reports and inspection results.
- Purchasing and warehouse: purchase requests and orders, supplier comparison, provisional and final receipts, issue slips and real-time stock across several warehouses; warehouse history cannot be tampered with.
- Finance and administration: budget lines, payments with receipts, invoices, incoming and outgoing letters, and users’ digital signatures on documents.
We describe each department in detail on the Data factory management software page; this page focuses on the deployment model itself.
A Day Without Internet in a Factory Running Data (Hypothetical Example)
Suppose the industrial park loses its internet connection at nine in the morning and it does not come back until evening. In a factory where Data is installed on the internal server, the day runs almost normally:
- The storekeeper books the incoming delivery on a provisional receipt and, after checking it, issues the final receipt.
- The planner takes the next order from the “ready for planning” list and sees its material requirements.
- The shop-floor supervisor records completed stages in their own inbox.
- The plant manager reviews and signs the requests in the approvals inbox whose deadlines are close.
What is affected that day is work that by its nature depends on the outside world. For example, if a manager wants to log in from home, that depends on whatever remote route your own network team has set up into the internal network. It is worth raising this in the demo session so your expectations are clear.
Transparent Support: No One Connects to Your Server Without Permission
A common worry about installed software is that the vendor can access the server whenever it likes. In Data the rule is the opposite: a P-Soft engineer connects to the server only after you consent, their presence is visible on screen for the whole session, and everything they do stays in the logs. Later you can still see who connected, when, and for what purpose.
The level of support depends on the plan. In Start, requests are logged and followed up through P-Soft’s official channel; Pro adds phone support and setup training; and Elite includes priority support, transparent remote support and a dedicated account manager.
Backups and Updates in an On-Premise ERP
When the server is in the factory, its physical upkeep is the factory’s responsibility too, but Data takes most of the load off your team:
- Automatic, safe updates: new versions install on the server automatically, and the system takes a backup of your data before every upgrade.
- Regular backups and simple restore: data is not lost during updates.
- Backups from the admin panel: from the Pro plan, the system administrator can take a backup directly from inside the panel.
One piece of general advice that applies to any installed system: make one person in the factory responsible for the server, give it backup power and a suitable room, and keep a copy of your backups somewhere other than the server itself. A backup whose restore has never been tested is only a hope.
On-Premise ERP vs Cloud ERP: A Fair Comparison
Neither model is better for everyone. The table below sets the differences side by side from the point of view of a factory’s daily work:
| Topic | ERP on the factory’s server (like Data) | Cloud ERP |
|---|---|---|
| Where data is stored | The factory’s own hardware | The provider’s servers |
| When the internet is down | Work continues on the local network | Access is usually lost until the connection returns |
| Buying and maintaining the server | The factory | The provider |
| Access from outside the factory | Depends on your own network’s remote access | Usually from anywhere with internet |
| Support engineer access | In Data, only with your permission, visible and logged | Depends on each provider’s policy |
| Better suited to | Factories with a local network and sensitive data | Dispersed teams and companies without an IT function |
To be fair: if most of your users work outside the factory, or you have no one to look after a server, the cloud model has real advantages. Data has no cloud version, and we say so plainly from the start.
Who This System Fits, and Who It Does Not
Data is built mainly for make-to-order manufacturers that produce parts to customer drawings and involve several departments in every order. The on-premise version suits:
- A factory with a local network that wants the shop floor, warehouse and office working from the same information.
- A manufacturer that does not want its drawings and prices on a third party’s server.
- A multi-site industrial group that wants each site’s data kept separate (Elite plan).
And it is not the right fit if you are looking for payroll, HR, time and attendance, tax or e-invoicing software: Data does not include these, and its focus is the chain from inquiry to delivery. If your company policy allows only cloud services, Data is not the option for you. The software interface is in Persian (right-to-left, with the Persian calendar), so it suits teams that work in Persian; for make-to-order workflows specifically, see our make-to-order ERP page.

How to Set Up an ERP on Your Own Server
- Initial conversation and demo: your factory’s real process is reviewed and the plan is chosen to match the number of sites and departments.
- Server preparation: the server specification and its place on the network are agreed with P-Soft’s engineers.
- Installation and local network configuration: Data is installed on the server so it can be reached from the browsers of the factory’s computers and tablets.
- Roles and permissions: each user gets a separate role, so everyone sees only what they need to.
- Step-by-step rollout: master data is entered, one complete workflow runs first, and then other departments join.
Data supports light and dark modes. A dedicated desktop application is coming soon; until then, a browser is all users need.
Frequently Asked Questions
Does Data work without internet?
Yes. The system sits on the factory’s internal server, and as long as the local network is up, users work with it from a browser on computers and tablets.
Is there a cloud version of Data?
No. Data is offered only as an installation on the factory’s server; all data stays on your own hardware.
Do we need to install software on every computer?
No. Users connect through a browser; a dedicated desktop application is coming soon as an additional option.
Can a P-Soft engineer connect to our server without us knowing?
No. No connection is made without your consent, and every connection is both visible on screen and kept in the logs.
Does Data include payroll or e-invoicing?
No. Data is not payroll, HR, time and attendance, tax or e-invoicing software; it focuses on the chain from inquiry to delivery.
Can one Data installation serve several factories?
The Elite plan is multi-site and keeps each site’s data separate; the other two plans are for a single site.
