Customizing document numbers

Any document created in Quaderno, regardless of its status (paid, outstanding, …), will be given a sequential number with an optional prefix.
To add an optional prefix to your documents, and to reset the unique numbering sequence for your documents, head to the Preferences page.
For each document type, you can modify the following:
  • Prefix: Letter or number combination to be included before each document number.
  • Number: Number of the next document that will be created. By default, you'll see the next number in your current sequence in Quaderno.
This way, you can ensure your next document in Quaderno will be assigned a sequential number. This is particularly useful if you are migrating to Quaderno.
Add the tag {{YY}} or {{YYYY}} to use the current calendar year as the prefix.
In order to prevent ordering issues, the sequence should have at least as many digits as the number of documents expected to be created in a year. For example, if you expect to issue 1000 documents this year, we'd recommend at least four digits (i.e. "001", "0001", "00001", etc) in your number sequence.
While letters are supported in the number field, if you use "ABC" in the numbering sequence, the next document will be assigned "ABD". Given this, we do not recommend using letters in the number field. We recommend using letters in the prefix only.
Boom! Custom document numbers with no fuss.


Can I add a suffix?
No, at the moment Quaderno only supports prefixes in the document numbers.
Can I have multiple sequences for one document type?
Quaderno supports one sequence per document type. If you'd like to use another sequence, we recommend creating another Quaderno account.
Will my document numbers reset every year?
By default, your documents will continue to be generated in the same sequence. If you'd like to reset the invoice sequence at the beginning of each year, you can enable that option on the preferences page with the option Reset document numbering at the beginning of the year.
I've already issued some documents. Can I change their numbers?
To comply with international invoicing guidelines, changes to document numbers for existing documents are not permitted.
Which symbols are supported?
The prefix field allows numbers, letters, and underscores, as well as the special tags {{YY}} and {{YYYY}} . You can use any symbol in the number field, though we recommend using only numbers.
