Compiere/Adempiere

One of the most important open source ERP projects, Compiere (and the recently created fork Adempiere) are complete and sophisticated mid-tier ERP systems. Among the features:

Standard and Customizable Financial Reports - Generate standard financial and managerial reports including Balance Sheet, Profit and Loss, Statement of Cash Flows and many others. Additional reporting options include customizing reports with Compiere's internal report writer, data access using your choice of 3rd party report writers, or data exports for analysis in spreadsheet or OLAP tools.

Comprehensive Financial Management - Compiere offers comprehensive financial management capabilities. All functional elements of Compiere are global-ready, supporting the complexities of businesses that span multiple organizations, currencies, accounting schema, tax laws and languages. Compiere enables you to customize the system to meet your needs without risking violation of accepted accounting and tax rules.

Customer-specified Chart of Accounts - At the heart of every financial accounting system is a chart of accounts. Compiere ships with several charts of accounts for you to use. It also provides a streamlined process for you to continue using your own chart of accounts.

Accounting Rule Enforcement - Compiere strictly enforces base accounting rules to ensure balanced accounting entries and overall system integrity. An example of a base rule is that the system will reject an entry if the accounting date is in a closed period.

Tax Calculation and External Reporting - Most tax entries are created by the transaction. Compiere calculates, manages and applies multiple taxes (e.g. GST/PST) as well as local tax. Tax rules create correcting tax entries for Sales Tax and VAT systems. Compiere automates the preparation of reporting to external tax agencies.

Banking Relationship Management - Compiere automates the management of your banking relationships and accounts. Compiere supports the import and export of bank statements using OFX, IFX and SWIFT formats.

Quotations - Compiere provides for the creation and printing of customer quotations based on general or customer specific price lists. Quotations can be made "binding," in which case they reserve inventory. Quotations may also be modified at any time and can be automatically converted to a Sales Order without additional data entry.

Sales Orders - A Sales Order is the "fulfillment control document" that is the foundation for generating Sales Order, shipment and invoicing documentation. In addition, Vendor Purchase Orders may be created automatically for the items specified on a sales order and directly shipped to the customer if appropriate. Different types of sales orders cause different business process behavior in Compiere. For example, a "Prepaid Order" will not allow shipments until payment occurs. A "Point of Sale" order assumes the customer is at the counter with the goods in hand and generates all transactions including stock decrement, invoicing, and payment through the entry of a single document. A "Standard Order" by comparison, will check availability before accepting the order then queue the order for fulfillment by the warehouse and then generate an invoice in the next invoice run or otherwise in accordance with the invoice rules for that customer. Compiere supports the following Sales Order Situations: Standard order, POS order, credit order, warehouse order, prepay order, RMA.

Shipments - Based upon the details captured on the Sales Order, one or more shipments can be generated immediately or automatically when inventory subsequently becomes available. Compiere automatically back orders unavailable items. Compiere can be configured to allow shipments to be effected from the shipment documentation or alternatively provide for a more disciplined warehouse approach by requiring explicit confirmation of picking and/or shipment prior to the generation of invoice documentation. Confirmations can be used to manage movements of inventory from, say, a receiving area to 'put away' areas from which it then becomes available for further processing.
