Numbering module for invoices
Every company uses different numbering formats for their invoices. Dolibarr includes several sub-modules that implement different numbering rules/formats. Only one sub-module can be used.
There is also a module that allows you to specify the format from a template mask. Hover the cursor over the help icon to see the comprehensive syntax available to define the template.
Note: If there is no numbering sub-module that matches your format, you can still hire a developer to build one!
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.
