The legal floor
Under Article 12 of the Saudi Companies Law, contracts and other documents issued by a company must show its name, legal form, head-office address, email and commercial registration number, together with its capital and paid-up capital (Companies Law, official English translation).
Since the new Commercial Register Law took effect in April 2025, the CR number is the ten-digit unified national number. Templates that still print an old number are out of date (Clyde & Co, September 2025).
Tax invoices follow their own rules set by the Zakat, Tax and Customs Authority (ZATCA), including the seller's VAT number and a QR code from an approved e-invoicing system (ZATCA e-invoicing guideline). Your accountant or tax adviser should confirm what applies to you.
Five habits of well-run document sets
1. One source of company details: every template reads the same name, numbers and address, so a change is made once.
2. Arabic first where the law requires it, with English alongside; agree in the contract which language prevails.
3. A version on every template and a named owner who updates it when the law or the company changes.
4. Approved wording only: legal text comes from your lawyer and is inserted unchanged.
5. A yearly check: registrations, addresses and capital lines are reviewed against the official records.
Companies across the GCC follow similar rules in each country; if you trade in more than one market, keep a template set per jurisdiction.
Where to start
Collect every template in use (letters, proposals, contracts, invoices, email signatures) and compare them with your official records. A short governance review shows what is missing, what is outdated and how to keep it right. This article is general information, not legal advice.
