Keep a sequence and an independent archive
The first PDF download assigns a number by locale, document type and year. Separate browsers have independent counters. Account for any other invoicing tools before using this sequence.
Keep your PDFs and a JSON backup elsewhere. Local history keeps 50 documents and is not a legal archiving service. Importing a backup replaces the current local data after confirmation.

Assigned on first PDF export. Numbering is local to this browser.
Use one browser for each numbering sequence. A PDF export cannot maintain a sequence across several devices.
Your documents are saved in this browser. Clearing browser data removes them. Keep a JSON backup.
