Numbering module for invoices
Every company use different numbering rules for its invoices. For this, Dolibarr propose several sub-module that implement different rules. Only one sub-module can be used.
There is also a model that allows you to specify the way to forge the number from a mask template. Place the mouse hover the help pictogram to see the syntax to define such a mask.
Note: If there is no numbering sub-module that match you own rule, you can still hire a developer to build it.
Invoice documents models
Also, you can use several predefined invoices document models. To build an invoice using a particular model, go on invoice tab and, in the array "Documents" at the bottom of the page, choose the model and click on "Build" to generate the document for invoice from this model.
All models are available in directory htdocs/core/modules/facture but to have them active and to be able to select them to build documents, you must first activate them on the invoice module setup page.
