The two sound alike and are easy to mix up. In short: the document title is printed at the top of the PDF; the document name is the name of the design, and only you see it.
Both belong to a document design, so both are set in Settings → Document designs — but in two different places inside it.
Document name
The document name is the name of the design itself. It exists so you can keep your designs organised when you have more than a few, and it is what the Name column shows in the designs list.
To change it, open the design and edit Document Name in the General panel on the left.

You can also rename a design without opening it: from the designs list, use the row’s Action → Modify, which takes the Name along with the design’s document type and language.
So an invoice design can be called Invoice (test customer) while the title printed on the PDF still reads Invoice. Your customer never sees the document name.
Document title
The document title is the heading printed on the document PDF — create an invoice and the title on the PDF reads Invoice. The designs list shows the current one in its Title column.
It is not in the General panel. It is one row in the design’s Field names and values:
- Open the design and find the Field names and values card at the bottom of the left column.
- Switch Use default design off. Modify Field names and values appears.
- Click it, find the Document title row, and type the heading you want in its Field name — Fee note instead of Invoice, for example.
- Save with Modify Field names and values.

Document title is the only row in that table with a Show default value switch and a Field default value of its own; the other rows just rename their labels — see How to change the label name.
Because designs are held per language, set the title on the design for each language you send documents in.
Which one do I want?
| You want to change | Use |
|---|---|
| The heading printed on the PDF | Document title (Field names and values) |
| What a design is called in your account | Document Name (General, or Action → Modify) |
| The file name of the PDF sent by email | Document name .pdf (Settings → Company settings) |
The PDF file name is a third, separate setting — see How to change the document PDF name.
