How Odoo connects to ZATCA (what most providers don’t tell you)
Simulation first
Each sales journal is tested in ZATCA’s simulation portal. Simulation invoices are not legally valid, so testing is safe.
One-time code per journal
Every invoice journal is onboarded with its own 6-digit code from the Fatoora portal. The code expires in 60 minutes, so we do it together with your finance team.
Live mode is final
Switching a journal to production cannot be undone, so the invoice layout, taxes and customer data must be right before go-live.
Arabic invoices
Tax invoices must be in Arabic. Odoo can print Arabic only or bilingual Arabic/English invoices and POS receipts.
POS rules
Point of Sale orders need a customer on the order to issue a compliant simplified invoice. We set this up so cashiers are not slowed down.
Rejected invoices
If ZATCA rejects an invoice, it must be corrected and sent again. We train your team on what to check.
Based on the official Odoo documentation for the Saudi Arabia localisation (Odoo 19).
Odoo Community, Enterprise or Odoo Online: which one fits?
| Odoo Community | Odoo Enterprise (on-premise or Odoo.sh) | Odoo Online (cloud) | |
|---|---|---|---|
| Who it suits | Small teams with simple needs and in-house IT | Growing companies that need payroll, Studio or custom work | Companies that want no servers and quick start |
| ZATCA e-invoicing | Often needs add-on modules; we check the version first | Official Saudi localisation | Official Saudi localisation |
| Saudi payroll (GOSI, WPS) | Add-on modules only | Included in the Payroll app | Included in the Payroll app |
| Hosting | Your server or ours | Your server or Odoo.sh | Odoo cloud, MENA customers hosted in Dammam |
| Customisation | Full code access | Full code access and Studio | Studio only, no custom code |
Licence on your own Odoo subscription. Setup, data migration, training and support by our team. We recommend the edition only after we see your processes.
Moving from Excel, Tally, QuickBooks or a simple accounting app?
If you only need invoices and tax returns, a simple Saudi cloud accounting app such as Qoyod, Daftra or Wafeq can be enough. We will tell you honestly if that is the case.
Odoo makes sense when you also need inventory across branches, POS, purchasing approvals, payroll, CRM or manufacturing in the same system, or when your team has outgrown spreadsheets. We move your customers, suppliers, products, opening balances and open invoices, so you start clean with ZATCA from day one.
What affects the cost of an Odoo project?
- Number of users and which apps you need
- Odoo edition and hosting (cloud, Odoo.sh or your own server)
- Data migration from your current system
- Custom reports, approvals or integrations
- Training and after go-live support
We give you a fixed-scope proposal after a free discovery call, so there are no surprises.
Your data in Saudi Arabia, protected by a cybersecurity team
Odoo hosts new MENA cloud customers in Google’s Dammam data centre, which helps with Saudi data protection (PDPL) questions. If you prefer your own server, we can host Odoo in your office or data centre.
Waves is a cybersecurity company first: we add MFA, backups, firewall protection and user access reviews around your ERP, the same controls Aramco CCC and NCA auditors ask for.

Odoo & ZATCA: frequently asked questions
Is Odoo compliant with ZATCA Phase 2 e-invoicing?
Yes. Odoo has an official Saudi Arabia localisation that connects to ZATCA’s Fatoora platform: B2B (standard) invoices are cleared and B2C (simplified) invoices are reported, with the QR code printed on invoices and POS receipts. Older Odoo versions and Community setups may need extra modules, so we always check your version first.
Which ZATCA wave am I in, and what is my deadline?
Wave 25 covers businesses whose taxable sales went above 187,500 riyals in any year from 2022 to 2025, and they must be connected by 1 February 2027. Wave 24 (above 375,000) had to connect by 30 June 2026. Your exact wave is shown on the ZATCA Fatoora portal, and you can use the checker on this page.
Odoo Community or Enterprise: which do I need?
Community is free and fine for simple needs, but ZATCA and Saudi payroll often need add-on modules. Enterprise includes Odoo’s official Payroll app, Studio and full support from Odoo. We recommend one only after a discovery call.
Can Odoo print Arabic and English invoices with the QR code?
Yes. Odoo can print Arabic-only or bilingual Arabic/English tax invoices and POS receipts with the ZATCA QR code.
Does Odoo handle GOSI, WPS and end-of-service?
Odoo’s Saudi payroll calculates GOSI by nationality, accrues end-of-service every month and exports the WPS salary file for your bank. The files are uploaded by your team; Odoo does not submit directly to Mudad or GOSI.
Can you move my data from Tally, QuickBooks, Excel or another app?
Yes. We migrate customers, suppliers, products, opening balances and open invoices, and check the totals with your accountant before go-live.
Where is my data hosted?
On Odoo Online and Odoo.sh, new Middle East customers are hosted in Google’s Dammam data centre in Saudi Arabia. You can also run Odoo on your own server.
How long does it take to go live?
A focused first phase (accounting and e-invoicing) is usually much faster than a full ERP project. Inventory, POS, payroll and manufacturing are added in a second phase. You get a fixed go-live date in the scope.
What happens if ZATCA rejects an invoice?
The invoice must be corrected and submitted again. We set up the invoice layout, tax codes and customer data properly to avoid rejections and train your team on what to check.
Do you support companies outside the Eastern Province?
Yes. We are based in Al Khobar and visit companies in Dammam, Jubail and Dhahran, and we support companies in Riyadh, Jeddah and across Saudi Arabia remotely and on-site.
