Numbering works through templates, because each template keeps its own counter.
- Document number gives every document sent from a template the next number automatically. In a new template you choose the starting number and how many digits it has, for example 000123.
- Linked number repeats the number of another document, for example an agreement that refers to the order form it belongs to. In a template you choose the linked document each time you send.
If these buttons are greyed out, save the document as a template first.
