Questions about Invoice Number Generator
Where is my invoice data stored?
Local records are saved in this browser. Clearing browser data removes them, so keep a CSV or JSON backup. Starter and Pro can also save and sync records in the cloud.
Do I need to register?
No. Local basic tracking works without an account. Cloud save and sync are included with Starter and Pro.
Can I export my invoices?
Yes. Raw CSV and JSON backups are free. Formatted Excel and PDF statement reports are included with Starter and Pro.
How does this relate to the invoice generator?
The generator creates invoices; this tracker records balances and due dates. Choose “Track this invoice” after downloading or sending an invoice, or “Track” in dashboard history. The copy stays independent of later generator edits.
