2.2) Pros & Cons
A very capable software with features capable of running a medium company. Well designed so that the basic user is able to install and use it
To make maximum use of it’s potential you must know a bit of server configurations
Although webERP is a powerful enterprise system, the developers admit that it is best suited for manufacturers, distributors and wholesalers. Retail businesses looking for a complete system have to combine webERP with third-party POS software. Small and medium-sized organizations will find webERP to be surprisingly simple yet very effective, but it is not powerful enough to handle the needs of large businesses. A demo is offered for a quick overview of the system, and full downloads are available through Sourceforge.

3.2) Pros & Cons.
- Open source, GPL’d and an active developer community
- It is easy to customise
- Provides full double entry accounting
- Has solid modules that handle General Ledger,Sales & Order, Accounts Receivable, Accounts Payable, Purchasing, Inventory, Bank and reconciliations
- Has additional features such as an Asset management module, Petty Cash, Contract Management
- Provides HTML or PDF reporting
- Multi-language support and fully UTF-8 compliant
- Has inbult auditing trail, and roles based security system with configurable page access per role
- Easy custom reporting defined and run from the web interface
- Manufacturing and with Material Requirements Planning
- The features relating to Project and Task Management are not present.
- This app truly and totally depends on having a warehouse, and there’s no way to configure that away. It’s great if you have a warehouse, but it’s not geared towards companies , that have no physical assets to manage.
- There is no templating system leading to the usual problems and frustrations that occur when one has to program the user output rather than template it. There is a theme ‘system’ that allows simple css theming or skinning of the existing module functions.
- The program design is somewhat unusual these days. It is procedural wtih multiple scripts in the web root directory. While it took me some time to come to terms with this, I’ve learned to live with it for the moment, and can be somewhat placated knowing there is a solid security system in place.
