You may decide you want certain prefixes and suffixes to be used on your numbering system. You may also wish your new jobs, invoices, etc. to start with a specific number an increment from there. This is done in the Configuration Book on the Numbering Branch.
An example would be:
The first job you create will have a job reference J1000-RD and the next job J1001-RD.
Dispatch Notes, Orders and Invoices use the same system. However, Goods In Notes and Return Notes have their own suffix, but share the Central Number with the dispatch notes.
To modify a setting, type in the required value(s) and then press the 'Save' button.
