You have installed TAQNIX ERP and set up your company. Now you want to send a first invoice to a customer. This article takes about five minutes to follow and uses demo data in the pictures.

You need your company details filled in (your name, address and VAT number) and one customer. If you have not done this yet, the install guide covers the setup.

Step 1: open a new invoice

Open the new invoice screen. Choose the customer. If the customer is not saved yet, add the customer on the spot: you can write the name in Arabic or in English.

Then add the lines of the invoice: the item or service, the quantity and the price. The program adds the VAT and the total as you type.

Step 2: choose standard or simplified

A standard tax invoice is for another business that has a VAT number, so it shows the buyer’s details. A simplified tax invoice is for a consumer, like a till receipt, and does not need the buyer’s details. Choose the one that matches the sale.

Check the lines and the total once more. After you confirm the invoice, it gets its number and you should correct mistakes with a credit note, not by editing.

Step 3: confirm and look at the QR code

Confirm the invoice. The printed page now shows your company details, the invoice number, the date, the lines, the VAT and the total, and the QR code in the corner. The QR code holds five values that the law requires in Phase 1: the seller name, the VAT number, the date and time, the invoice total and the VAT amount.

You can test it yourself: point the camera of your phone at the code. Our free QR code checker also reads a code and shows the five values.

Step 4: print or save as PDF

Print the invoice on A4 paper, or save it as a PDF to send by e-mail. Saving as PDF needs Google Chrome or Microsoft Edge on your Mac; if you use Safari, install one of them.

The page is laid out for A4 with a clear table of lines and the QR code. The same invoice can be printed in Arabic or in English.

Step 5: a receipt for the shop counter

For a sale over the counter, use a simplified invoice and print it on an 80 mm receipt printer. The receipt is narrow, it lists the items in a short form and carries the QR code at the bottom.

If something is wrong later

When a customer returns goods or you charged the wrong price, issue a credit note that refers to the original invoice. If you charged too little, issue a debit note. Both show on the customer’s account and in your VAT figures. Our credit note calculator shows how the VAT is worked out.

What about Phase 2?

Everything above works with Phase 1, which is on from the first day. Phase 2 e-invoicing integration is built in and optional; try it in ZATCA’s test environment first; you switch it on yourself. Read our Phase 2 article when your wave is announced.

A short checklist

Before you send an invoice, look at these points:

Your seller name and VAT number are correct in the company settings.
The customer’s name is written correctly. For a standard invoice, also the VAT number and the address.
The VAT rate on each line is the one you expect.
The QR code is visible on the printed page and on the PDF.
