    KwaMoja

    KwaMoja

    Out of Africa comes KwaMoja. A fresh start for webERP!

    KwaMoja is designed to help you manage your business in a more efficient and profitable manner. It combines your book keeping needs with all the tools to plan your inventory purchases. It will let you know when your factory needs to start manufacturing parts in order to keep up with orders. It will help you better manage your cash flow. All these and more will help your business become more efficient, and greater efficiency will equal greater profits. KwaMoja is a fork of the once popular webERP project. WebERP has suffered in recent years with an increasingly abusive and dishonest style of management, which has seen the number of downloads go into decline. Many of us felt that the time was right to move the project on in a more open and community driven style.
