How to create a professional PDF invoice

Use complete business and customer details, itemize work clearly, define payment instructions, and review the PDF before sending.

  • Use a unique invoice number
  • Set an explicit due date
  • Keep descriptions specific and concise

Invoice totals, taxes and discounts explained

Nexynto calculates each line deterministically: quantity × rate, less discount, then tax on the discounted amount.

  • Review jurisdiction-specific tax rules yourself
  • Confirm currency and locale presentation
  • Compare the displayed breakdown with your records

Frequently asked questions

Is this a regulated electronic invoice?

No. It creates a standard PDF and does not submit data to a tax authority or e-invoicing network.

Are totals rounded consistently?

Yes. Fixed-point integer calculations are used instead of floating-point currency arithmetic.

Is the invoice uploaded?

No. Invoice generation runs in your browser.
