# Numbering

## Numbering

Numbering settings set the Mask for any system-generated number on new Folder, Project or Estimate, Invoice, Order, etc. This Numbering mask can be assigned to Project type, for instance.

### Numbering Mask

The mask is quite flexible, you can combine several system files, serial number & text strings.

For instance: "INV"YYS generates the invoice number like INV110001 for the 2011 year.

## Serials

Serials are used to track last number used in Numbering. Serials allow to track several numbering sets, based on Counter Reset Criteria. You can reset the counter automatically based on Organization / Account (Folder) / Project / Master Project / Year / Quarter or Month. (User is not applicable).

Once you need to change last number used, go to Serials &amp; amend the "Next serial" field by double-clicking on appropriate Mask row. (Please note that Next serial number displays **Last used** number in given Reset Criteria).

In order to amend Serials, go to: Settings -&gt; Serials
