Which category does your organization fall into?

Every organization falls into one of the following ERP user categories.

category #1. These organizations, often SMEs, do not have IT employees with proficient skills to perpetually customize ERP applications to ever changing needs.

Cloud ERP subscription services are these organization’s ideal choices if and only if all of the following criteria are met:

  1. The subscription fees are affordable (cheap) to subscribers.
  2. The ERP cloud service provider, third parties or you — the subscriber — can and are willing to perpetually customize your ERP instance according to your distinct requirements.
  3. The ERP cloud service provider allows you, the subscriber, to “get off the cloud” at any time and deploy the ERP software system and database in your own infrastructure, especially as your business grows.

category #2. These organizations (usually larger ones) have IT staff with skilled expertise who can permanently customize ERP applications to the changing needs of the organization.

On-premise ERP software are these organization’s ideal choices because

  • of the cost. Considering the amount of storage required for the dataset, the server computing power required, and the network bandwidth required, the total cost of running on-premises ERP software for large organizations is often much lower than a cloud subscription.
  • The quality of service, especially response times, of your organization’s IT staffs who may be sitting in the room next to you is often much better than that of a cloud ERP provider.
  • IT staff with savvy ERP skills will feel respected when they have access to tangible on-premises ERP software and databases.

category #3. Super large organizations like military and defense have a large IT army with proficient IT expertise.

On-premise ERP development and execution frameworks that provide full software source code and documentation options are the best choice for these organizations for two reasons:

(3a) Governments want to avoid being locked in (or kidnapped) by ERP vendors.

There are two facets of ERP vendor lock-in’s: ERP software and Relational Data Base Management System (RDBMS).

(3a1) As an IT decision maker in a key government sector, you know exactly if you’re locked into an ERP vendor.

Powerful IT specialists in critical government departments not only want to customize ERP applications on an ERP framework, but also want to continuously improve the ERP framework itself.

Backed by a powerful IT team, you, the ambitious IT decision maker in a large critical government department, may one day decide to cut ties with your ERP vendor in the interest of taxpayers that pay you well and go with your own independent IT development route.

Does your ERP software vendor permit you to achieve your ambition?

Large organizations with strong IT teams can purchase the source code for PostERP, a low-code ERP development and execution framework.

(3a2) Did your ERP software vendor ever hint to you: “Your IT women and men are just incompetent to pursue your own way of information technology because our grandeur ERP software comprises a million lines of source code and is 100 GB in size. Besides, its source code is the rocket science accumulated over 50 years, not for sale.”?

Or, do you come to the same conclusion yourself?

The compressed source code of PostERP is smaller than 10 MB.

Can’t your IT army of 500 engineers take over my task of constantly enhancing the light-weight PostERP framework so that your version outperforms mine?

(3b) Governments, especially the Department of Defense, want to ensure that there is absolutely no (implanted?) backdoor in ERP software, RDBMS, and operating systems (OS).

(3b1) As the IT decision maker in a critical government sector, are you sure there absolutely is no backdoor in your ERP software?

PostERP framework is built entirely on Free Open Source Software (FOSS), except for the reporting component.

You can buy the source codes of PostERP framework and your IT experts can scrutinize every single line of PostERP code to verify the possible flaws in the framework.

(3b2) Are you sure there absolutely is no backdoor in the RDBMS you are using?

PostERP is powered by the battlefield tested PostgreSQL, a FOSS.

(3b3) As the IT decision maker, you perfectly understand the quality of the bloated and slow crawling Windowz 10, 11,…20. But like me, you probably have no idea how many backdoors there might be in that OS.

PostERP server runs best in Linux.


I am offering the low-code PostERP as both services and on-premise products to all organizations in all of the aforementioned categories. I don’t lock in any organization of any size.
