Frequently asked questions about invoices
How do I create my first invoice?
In your portal go to Invoices → New invoice. Pick a client, add lines, verify the auto-calculated VAT and click Send. Done in about 30 seconds.
Are invoice numbers generated automatically?
Yes. Invoisio numbers sequentially based on your chosen format (e.g. F-2026-001). Format and start number are configurable via Profile & Company. No gaps — fully compliant.
