Try an example

Choose Fill in an example: three packs of paper at 12.50 and three ink cartridges at 32.50 give a subtotal of 135.00, tax at 10% of 13.50 and a total of 148.50.

What to expect

Amounts use two decimals. Each line is quantity × unit price, rounded half up to the cent; tax is the rate applied to the subtotal and rounded the same way. Quantities can have up to three decimals, for example 1.5 hours.

The PDF uses the standard Helvetica font for English and Western European text and embeds Noto Sans fonts for other Latin, Greek, Cyrillic, Hebrew, Arabic, Chinese, Japanese and Korean letters. If you type characters these fonts cannot write, such as emoji, the page names them and does not create the file. The layout is a plain professional template; check tax rules and required invoice details for your country before sending.

Your entries are kept only while this page is open. Reloading or closing the page clears them.

A practical guide

Itemised invoice for lab services

  1. Enter the lab, the client and the invoice reference.
  2. List each service with quantity and unit price.
  3. Create the PDF and file it with the project record.

Try this example

Invoice 12 sample analyses at 45.50 and 2.5 instrument hours at 80.00; the PDF should show 546.00 and 200.00 and a subtotal of 746.00.

Before you start: Amounts use two decimals with half-up rounding per line and on tax; nothing is kept after the page closes.
