For default Magento store generates orders such as: 100000001, 100000002, 100000003, etc. It's not very good for your accounting. Most likely you and your customer prefer invoice numbering such as IN1-007/13, IN2-008/13,... With FlexInvoice you can setup it very easy in your eshop.

FlexInvoice (Custom Order Number) extension overrides a standard Magento numbering model for invoices, orders, shipments and creditmemos. The extension provides you possibility to customize your orders, invoices, shipments and creditmemos. For example, you may setup the auto incrementing numbering for your orders: OR1-0001/2013, OR1-0002/2013, OR1-0003/2013, ...

Each number model (invoices, orders, shipments and credit memos) supports a variety of settings, such as prefix, suffix, start value, etc. The below you may see all features that provides by the FlexInvoice extension.


  • Fully customise order, invoice, shipment and credit memo numbers using any combination of letters, numbers and dates
  • Supports EU accounting system:  where may not be a gap in the numbering  of credit memo and invoice
  • Set custom prefix for orders, invoices, shipments and credit memos
  • Set custom postfix for orders, invoices, shipments and credit memos
  • Set starting numbers for orders, invoices, shipments and credit memos. You may start at 1 or easily continue from where you left off under an existing numbering system
  • Set increment step for orders, invoices, shipments and credits
  • Set the length of order numbers via custom padding length
  • Set the Max number value: after reaching the maximum value, the number resets to start value
  • Reset on the 1st of January (New Year): the numbering will be reset to start value
  • Supports templates for prefix and postfix: %STOREID%, %YY%, %YYYY%, %MM%, %M%, %DD%, %D% and %W%
  • Order, invoice, shipment and credit-memo numbers generate automatically
  • Supports Multi-Store Environment: Increment by Store, Website or Global

Outstanding support ! Great extension !

Review by Pierro74 | Jun 11, 2011

After buying and installing this extension, we experienced few bugs. This was mainly due to our configuration and Magento version, nothing related to code quality! To solve these bugs we got a near real time support from Alex. Our issues were solved within only 2-3 days (and that included a weekend !).

This extension should be a native functionality for Magento ... as far it is not, this extension is a must have!
Excellent extension

Review by myst2 | Jun 11, 2011

Excellent extension, i have installed it with ease and have encountered no bugs at all. Now my order numbers, invoices and so on looks much more professional, not the ridiculous #10000000012 by default in magento. Highly recommended. Thanks!
