Changing the Document Number Sequence
To change the next number SliQ Invoicing assigns to a new document, e.g. to a new invoice, open the Options dialog by pressing the Options button in the toolbar.
SliQ will then display the Options dialog
Make sure the Document Number Sequences tab is selected on the Options dialog.
Change the next numbers to be used when new documents are created.
By default, SliQ warns you if you create a document such as an invoice with a number that has already been used, e.g. it warns you if you create two invoices with the invoice number 1023. By unchecking the Warn if a Duplicate Number is Entered box you can stop SliQ giving you a warning.
Note: Delivery Note numbers are automatically set to the same number as their accompanying invoice.
