1Four corners is the classic Peppol exchange
You, your service provider, your customer's service provider, your customer. Each side deals only with its own provider, which is what makes the network scale.
You will see this diagram in every vendor deck. It is worth understanding once properly, because it explains why you cannot simply email an XML file and why the tax authority sees your invoices without asking for them.
If you take four things away from this page, make them these.
You, your service provider, your customer's service provider, your customer. Each side deals only with its own provider, which is what makes the network scale.
The UAE model adds the Federal Tax Authority as a recipient of the invoice data. That is what makes this continuous transaction control rather than plain exchange.
There is no government website you upload to. The network carries the invoice and the authority receives its copy through the same flow.
The design has no route for an ordinary business to connect directly. The provider is the on-ramp, and there is no bypass.
Everything here can be done before you commit to a provider or a system.
Our e-invoicing product is being built now, alongside the ERP, CRM and accounting systems our technology team already runs for UAE clients. Early-access clients get their requirements built into the core rather than bolted on afterwards, which is genuinely better for them and better for the product. Start with invoicing and add the rest when your business actually needs it.
GoldenKey is a business setup and compliance consultancy. We are not a Ministry of Finance Accredited Service Provider, and we do not claim to be one. Our software is built to work alongside the ASP you appoint. Scope, timelines and pricing are agreed in writing before any work starts.
Short, practical answers. If yours is not here, ask us directly — we answer even if you never become a client.
Sender, sender's service provider, receiver's service provider, receiver, plus the tax authority as a fifth corner receiving the invoice data.
The model is decentralised by design. Invoices travel through accredited providers on the network rather than through a central government portal.
For the exchange to complete, yes — both sides are on the network. Counterparties in the same wave face the same deadlines you do.
Excel, Tally, Zoho, an ERP or paper — send us your current setup and we will tell you what has to change and what does not.
No cost, no obligation. We tell you which phase you fall into and what you actually need.
GoldenKey covers every step — start, run, grow — under one golden roof:
