Why this choice needs care

Odoo users in the UAE now have more than one way to add e-invoicing, because Odoo’s app store lists several third-party UAE e-invoicing modules, and providers and partners offer their own connectors. However, they differ in versions, hosting, provider links, invoice types, support, and cost.

Therefore, the cheapest option on the day you buy is not always the cheapest over three years. Furthermore, a connector that does not match your Odoo version, or that cannot run on your hosting, costs more than it saves. Consequently, this guide gives you a fair way to compare, and it works for any option.

What a connector does, and what it does not

First, a connector turns an Odoo invoice into UAE e-invoice data, checks it against the rules, passes it to an accredited provider, and shows the delivery status in Odoo. Furthermore, a good one also helps you receive supplier invoices. However, it cannot decide your tax codes, and it cannot collect the missing tax registration numbers from your customers.

Step 0: check your Odoo hosting first

If you are on Odoo Online, ask Odoo and your partner what options exist for UAE e-invoicing, including a move to Odoo.sh or on-premise. Please confirm the current position with Odoo, because hosting rules and Odoo’s own UAE features can change.

The 12 questions to ask

Questions 1 to 4: does it fit your setup?

1. Versions and editions: Ask which Odoo versions and editions the connector supports, because one tested on Odoo 17 may not run on your version. Therefore, a good answer is a clear list, with Community and Enterprise stated.

2. Hosting: Ask whether it works on your hosting, because Odoo Online cannot take it. As a result, a good answer names Odoo.sh and on-premise, and explains the install.

3. Accredited provider: Ask which accredited provider it uses, and whether that provider is on the Ministry list, because invoices must travel through an accredited provider. Consequently, a good answer names the provider and its accreditation number, which you can check.

4. Provider fee: Ask whether the provider’s fee is included or separate, because a cheap module with a costly provider is not cheap. Therefore, ask for a written breakdown of every fee.

Questions 5 to 8: does it cover your invoices and data?

5. Invoice types: Ask which invoice types are supported, because credit notes, exports, free zone, and foreign currency each have special rules. As a result, you need a list of what works and what does not.

6. Checks before sending: Ask what is checked before an invoice is sent, because errors are cheaper to fix before sending. Therefore, look for pre-send checks with readable error messages for accountants.

7. Pilot testing: Ask how you can test during the pilot phase, because pilot testing carries no fines. Consequently, a good answer offers a sandbox or test mode, and help running test cases.

8. Data: Ask what data it needs and who fixes problems, because data causes most rejections. Therefore, ask for a data checklist and a clear split of who does what.

Questions 9 to 12: will it keep working, and what does it cost?

9. Rejections and status: Ask how rejections and delivery status are shown in Odoo, because your team must see failures quickly. Therefore, each invoice should show a status, with the reason for any rejection.

10. Updates: Ask how updates are handled, because specifications and Odoo versions change. As a result, you need a stated update policy and support response times.

11. Total cost: Ask for the total cost over three years, because licence, provider, setup, support, and renewals all add up. Consequently, ask for one written total, with renewal terms.

12. Exit and data: Ask what happens if you leave and where your data is, because invoices are tax records, and you must be able to keep them. Therefore, ask about export of archived invoices, and about data storage and access.

Red flags

Three ways to add e-invoicing to Odoo

Install a ready-made module: this is the fastest start and usually the lowest upfront cost, but you still need a provider, and you rely on the publisher for updates.

Have a partner build or configure one: this fits unusual workflows, but you should check the cost, and the long-term maintenance when specifications change.

Use a provider’s own Odoo connection: this gives you one supplier for the whole chain, but you should check which Odoo versions and hosting it supports.

A five-step way to use this guide

1. First, check hosting: confirm whether you are on Odoo Online, Odoo.sh, or on-premise, and which Odoo version you run.
2. Second, shortlist: pick two or three options, such as a ready-made module, a partner-built connector, or a provider’s own connection.
3. Third, send the 12 questions: send every question to every option, and ask for written answers.
4. Next, score the answers: mark each answer as clear, partly clear, or unclear, using the printable sheet in the PDF.
5. Finally, pilot test: run a test with your real invoice types during the pilot phase, because mistakes carry no fines.

UAE e-invoicing dates

Also, you can check any provider’s accreditation on the official Ministry of Finance list of accredited service providers. Furthermore, please confirm which financial year counts for the AED 50 million test, and whether your business is in scope, with your tax adviser.

Common questions
