Customizing your document numbers can help you differentiate between different files.
For example, you can add 2019 or 19 before document numbers to easily identify this year's documents or use a specific number to distinguish between different document types (quotations, invoices, etc.).
Follow these steps to change your document numbers:
- Go to Configuration > Number series.
- Change the numbers of the document types that you want to modify.
Example: Start the number with 2019 as shown below.
The next document created, will have the number 2019010001.
