What if your customer isn’t on the e-invoicing network yet?

Most explanations of UAE e-invoicing describe the simple case: you issue an invoice, and your customer receives it through the network.

There is a second case that every business will meet next year, and that I have rarely seen explained in plain words: what happens to an e-invoice when your customer is not on the e-invoicing network yet?

Not everyone starts on the same day

UAE e-invoicing is being introduced in phases. Under the Ministry of Finance’s current plan, businesses with annual revenue of AED 50 million or more must issue e-invoices from 1 January 2027. Everyone else follows on 1 July 2027.

Think about what that means for a small business. Your own start date is fixed. Your customers’ start dates are not yours to choose. Some will be on the network months before you, some on the same day, and some will take longer than they should.

So for a long time, an ordinary invoice run will contain both kinds of customer.

How an e-invoice travels

An e-invoice is not a PDF sent by e-mail. It is structured data. You send it to your Accredited Service Provider. Your provider passes it to your customer’s provider, which delivers it to your customer. At the same time, the tax data is reported to the Federal Tax Authority.

To find your customer, the network uses an electronic address. In the UAE that address is built from the customer’s tax number: the code 0235 followed by the first ten digits of their TRN.

That works when the customer has joined. When they have not, the address exists on paper but nobody is listening at it.

What the rules say

The Ministry’s Electronic Invoicing Guidelines (version 2.0, October 2026) cover this case directly. When a buyer has not yet implemented e-invoicing and has no address on the network, two things are required:

1. The e-invoice is still issued, but it carries a fixed placeholder address, 0235:9900000098, in place of the customer’s own. The invoice is reported to the tax authority. It is not delivered to anyone.
2. The customer still gets an ordinary tax invoice, for example a PDF, in addition to the e-invoice. They need it to recover input tax and to know what to pay.

There are two more placeholder addresses for other situations: one for a deemed supply, where there is no customer at all, and one for an export to a buyer abroad who has no address on the network.

In other words: your obligation does not wait for your customer. You report the invoice either way. What changes is whether anything is delivered electronically, and whether you also need to send the document the old way.

How SnapLedger handles it

There is one practical difficulty. No directory tells you in advance whether a customer has joined the network. The network answers only when an invoice is sent: it either accepts the address or says the customer is not registered.

So SnapLedger works in this order:

• It sends the e-invoice to the customer’s own address first.
• If the network answers that the customer is not registered, it sends the same invoice to the placeholder address, and the invoice is filed with the tax authority.
• It tells you plainly that this customer is not on the network yet, so you should send them the PDF as usual.
• It remembers this for that customer, and tries their own address again after a month, because they may have joined.

You issue the invoice once. You do not need to know who has joined, or keep a list of your own.

An e-invoice also identifies your customer by its business registration, such as the trade licence number. SnapLedger takes it from the customer record, so it is worth having there before your start date.

What to do now

If you run a small business in the UAE, three habits will save you trouble next year:

• Keep customer records complete: legal name, TRN, address with the emirate, and the trade licence number with its issuing authority.
• Keep sending the PDF until you know a customer receives e-invoices. During the transition it is expected, not a workaround.
• Do not wait for your customers. Your date is your date.

If you want to see how an e-invoice is issued, checked and corrected in practice, our UAE e-invoicing course walks through it. This is general information about the published rules, not tax advice. For your own situation, ask your tax adviser or your Accredited Service Provider.

Lesson of the day: a rule is only finished when it also works for the customer who is not ready yet.
