Xero e-invoicing in the UAE is now built in. You register in Invoici, Xero’s e-invoicing platform, and appoint Casim as your Accredited Service Provider. This guide is from Scope, the only Xero Ambassador in the UAE: how it works, what your customer records need, and what stops invoices sending.
The only Xero Ambassador in the UAE
Xero calls Scope “our Xero ambassador for Malta, Cyprus and the UAE”. Read Xero’s announcement.
Xero’s UAE ASP
It is built into Xero, not a separate app. Casim’s technology sits inside Invoici, so you do not deal with Casim directly. You do accept Casim’s agreement when you register.
Source: Xero Central and Xero’s UAE pages. Checked 8 November 2026.
An e-invoice is a structured data file, not a PDF. Xero validates the data before anything leaves, and tells you if something is missing.
Based on Xero Central’s UAE e-invoicing article. Invoici is pre-live, so Xero says screens and steps may change.
Your VAT TRN certificate or, if you are not VAT registered, your Corporate Tax certificate. Enter the entire number when asked.
Sign in at uae.invoici.net with your Xero login and connect each Xero organisation. Registration is per organisation.
You accept it during Invoici onboarding. This is your contract with Casim as your ASP.
In Invoici, open your business, go to Settings and map each Xero tax rate to an e-invoicing tax category, for sales and for purchases. Set the Profit Margin Scheme rate and the Free Trade Zone default if they apply. You can change the mapping later.
Record Casim as your Accredited Service Provider in EmaraTax before your appointment deadline. Appointing early does not switch on live e-invoicing.
Every customer you invoice needs a complete address, the correct TRN and a business registration number in Xero’s formats. See the checklist below. You can bulk-update contacts by export and import.
Xero creates an eInvoice Category tracking category when you register. Use it, or set description lines, for e-commerce, continuous supply, summary, free zone and reverse charge invoices.
Send and receive on the Peppol test network now. You need a trading partner registered on the test network to test end to end. When production opens, send every invoice from Xero.
This is the data most businesses do not have yet. Start collecting it now.
| Xero contact field | What to enter |
|---|---|
| Name | The customer’s legal or trading name |
| Address | Legal trading address, filled in as the delivery address. Xero cannot send the e-invoice without one. In State / Region, spell the emirate exactly: Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain, Ras Al Khaimah or Fujairah. Customers outside the UAE still need this field filled in. |
| Tax ID Number | The customer’s 15-digit TRN. Where they apply, add flags after a semicolon: ;DEEMED for a deemed supply, ;AGENT:[principal TRN] for agent billing, ;FTZ for a free trade zone override. Example: 100123456700003;DEEMED;FTZ. For a customer outside the UAE, leave it blank: a foreign VAT number stops the e-invoice sending. |
| Business Registration Number | One format: trade licence CN-123456;DET (number;licensing authority), Emirates ID EID:[number], passport PAS:[number];[2-letter country code] or Cabinet decision CD:[number] |
| Transaction | How to flag it in Xero |
|---|---|
| E-commerce sale | eInvoice Category tracking 007 - E-commerce on the line |
| Continuous supply (lease, retainer) | Tracking 005 - Continuous Supply on the line |
| Summary invoice | Description line [Summary: yyyy-mm-dd, yyyy-mm-dd] |
| Free zone, beneficiary differs from buyer | Description line [FTZ: beneficiary ID] |
| Reverse charge line | Description line Reverse Charge: [Standard Item ID], [Commodity Classification Code] |
Save [email protected] on the customer’s contact as an additional person included in emails, or add it to the To field in the Send window. Then send from Xero. The invoice history shows the invoice was sent to [email protected].
This is the current pre-live process and may change for production.
Once registered, supplier e-invoices arrive in Xero as draft bills, whatever software the supplier uses. The original is attached as a .txt file for record keeping. Give suppliers your Peppol ID, shown in Invoici under Business Registration.
You must be registered to receive, even if your own sending deadline is later.
Xero cannot send the e-invoice. Contact clean-up comes first.
For customers outside the UAE the field must be blank, or the e-invoice will not send.
A PDF emailed from Outlook is not an e-invoice, and invoices raised in Stripe or other tools are not covered unless they are issued from Xero or given their own e-invoicing route.
Outside Xero’s offering. Ask your accountant how portal uploads sit alongside e-invoicing. You may run both processes.
You cannot receive e-invoices from suppliers that are already live until you register in Invoici.
Special transactions rely on description lines in exact formats, and the emirate must be spelt exactly. A small typo is easy to make.
Xero and Casim give you the connection. Getting invoices out correctly on day one is the work around it, and it is what Scope does.
| What Invoici and Casim give you | What still needs doing |
|---|---|
| Registration and your ASP connection | Tax codes mapped to e-invoicing categories, for sales and purchases |
| Conversion to the UAE format and validation | Customer records completed in Xero’s exact formats, and bulk imported |
| Sending and receiving over Peppol | Special transaction lines built into templates and repeating invoices |
| Supplier e-invoices as draft bills | Receiving tax mappings and a bill approval routine |
| Xero product support | Testing with a trading partner, team training and a send procedure |
| A plan for invoices raised outside Xero and for customer portals |
These are where an Impact Assessment earns its fee.
Until October 2026 that was true. Casim was named as Xero’s UAE ASP in mid-October 2026, and Xero now offers UAE e-invoicing through Invoici. Guides written before then are out of date.
We update this page when Xero changes the product. See the log at the bottom.
Yes. It is built in through Invoici, with Casim as the Accredited Service Provider. As of 8 November 2026 it runs on the Peppol test network, and Xero says production access will open before the mandate takes effect.
No. Xero includes it at no additional cost on Starter, Standard and Premium plans.
No. You register in Invoici and accept Casim’s agreement there. Xero has said product questions go to Xero support.
Xero has said you can register with your Corporate Tax registration number and certificate.
No. Appointment meets the ASP deadline, but tax mapping, customer records, testing and a new way of sending still need doing.
No. Invoices must be sent from Xero to be e-invoices.
Yes, as draft bills, whatever software the supplier uses, once you are registered in Invoici.
Xero has said a status dashboard is coming. Until then, check each invoice’s history for its transmission ID.
Not natively. Another ASP would need its own API connection, at extra cost.
Those are tax questions for your accountant or the FTA. See the deadlines by revenue.
