What is the 5-corner model in UAE eInvoicing?

It is the Peppol-based exchange model adopted by the UAE, where an invoice moves from your ASP to your customer's ASP, with tax data reported to the FTA in parallel.

Does KGRN provide support after eInvoicing go-live?

Yes. KGRN's support continues after go-live, covering connectivity monitoring, VAT reconciliation, master data health checks, and full managed operations for businesses that want KGRN to run day-to-day compliance on their behalf.

What happens if a business misses the UAE ASP appointment deadline?

Missing the appointment deadline reduces the time available for integration, testing and user acceptance testing before the mandatory go-live date, increasing the risk of disruption at launch.

You don't need a named ERP. You need the right connection to one ASP.

Why custom & in-house setups choose KGRN

Built Around Whatever You Already Run

No rip‑and‑replace. No requirement to adopt a named platform first. Just a compliant path that fits the system you actually have.

Connects to what you have

Whether it's a custom-built ERP, an in-house tool, a legacy system, or no software at all, KGRN meets you where you are instead of requiring a specific platform.

The 5‑corner model, handled

ASP middleware manages Peppol exchange and FTA reporting end‑to‑end, so your finance team isn't left configuring connectivity alone.

No developer team required, if you don't have one

Structured upload and guided onboarding get you compliant even without in-house developers — with a clear upgrade path to API or ERP integration later.

KGRN eInvoicing Platform

Built for How UAE Businesses Actually Operate

Not every business runs the same systems. KGRN's eInvoicing platform is designed around that reality. Whether your business has a full ERP, a lightweight accounting setup, or no billing system at all, the platform connects to where you are, not where the software assumes you should be.

Supports both AP and AR flows, with multi-entity businesses and separate ERP instances across subsidiaries and free zones managed under a single platform.

ERP Integration

Already running SAP, Oracle, Zoho, Tally, or another ERP? KGRN's eInvoicing platform integrates directly into your existing workflow. Invoices are generated, validated, and transmitted through the Peppol network without disrupting your current processes.

Direct API Access

For businesses without a full ERP, KGRN provides a dedicated API to generate and submit compliant invoices directly. Your developers connect once and the platform handles PINT AE formatting, digital signatures, and FTA transmission automatically.

Structured Upload

A practical starting point for lower-volume businesses or teams in transition. Submit invoices via a pre-formatted upload sheet covering all mandatory PINT AE fields. The platform validates, converts, and transmits. As your volume grows or your systems mature, you move to API or ERP integration with no re-onboarding required.

In plain terms

What Does UAE eInvoicing Mean If You Don't Run a Named ERP?

UAE eInvoicing requires businesses to exchange structured, machine-readable invoices through the Peppol network instead of PDFs or paper. That requirement applies whether you run a large ERP, a custom-built system, a legacy platform, or no accounting software at all. For businesses without a recognized, named ERP, KGRN's eInvoicing solution provides the missing layer directly: an API for your developers to connect to, or a structured upload path if you don't have development resources in-house. Either way, every invoice still needs to be converted into the PINT AE format, validated, and transmitted through an Accredited Service Provider (ASP) like KGRN before it reaches your customer, with tax data reported to the FTA in parallel.

How UAE eInvoicing actually works

The 5-Corner Model, Whatever You Run

UAE eInvoicing runs on a 5-corner exchange model. It applies the same way whether you run a named ERP, a custom system, or no software at all.

C1 · You (the seller)

Your ERP, custom system, or upload sheet issues the invoice as part of your normal sales process — no change to how your team works day to day.

C2 · Your ASP (KGRN)

KGRN's middleware converts your invoice into the PINT AE format, validates it, and transmits it through the Peppol network, regardless of where it came from.

Peppol Network

The certified exchange layer connecting accredited service providers across the UAE, so ASPs can transact regardless of which ERP sits behind them.

C3 · Buyer's ASP

Your customer's own accredited service provider receives and validates the incoming invoice on their end.

C4 · The buyer

Your customer's ERP receives a compliant, structured invoice — no manual re-entry required on either side.

C5 · The FTA

Tax data is reported to the Federal Tax Authority in parallel, keeping compliance in sync with the exchange itself.

How KGRN Supports Any System as Your Corner 2 ASP

As your MoF Pre-Approved ASP, KGRN handles everything at Corner 2, whether that means a live API connection, ERP integration, or a structured upload path.

Extracts and maps invoice data from your ERP, API connection, or upload sheet

Converts it into the mandatory PINT AE structured format

Validates mandatory fields and VAT logic before transmission

Digitally signs and transmits invoices through Peppol

Reports tax data to the FTA in parallel, as required

Returns delivery acknowledgements and exceptions back to you, however you're connected

Why timing matters

The Cost of Waiting vs. the Value of Starting Early

The ASP appointment deadline is fixed. How much runway you have before it isn't.

If you wait

Less time for integration testing before your mandatory go-live date
Manual re-entry and formatting errors creep into invoicing
Your finance team scrambles to build a connection under deadline pressure
Limited room to fix VAT logic issues once you're live

If you start now

A phased rollout you control, not one forced by the deadline
Time to clean up master data before it affects invoicing
A clear readiness check before spending on implementation
Confidence going into your go-live phase, without last-minute costs

Whatever you're running

Which Systems Can KGRN Connect To?

You don't need a named ERP to become compliant. Here's how KGRN connects, whatever your starting point.

Named ERP or Accounting Software

Already running SAP, Oracle, Zoho, Tally, or similar? KGRN integrates directly into your existing workflow via API.

Custom-Built or In-House System

If your business runs a custom-developed ERP or invoicing tool, KGRN connects through the same API and middleware approach, without requiring you to expose your system's internals.

Legacy or Proprietary Software

Older or niche systems can still connect through structured data exports, mapped into the required PINT AE schema.

No Billing System at All

Running invoicing manually or through spreadsheets? KGRN's structured upload path gets you compliant without needing to adopt a full ERP first.

You don't need to hire a new team

KGRN Works Alongside Your In-House IT or Development Team

If you have an internal team maintaining your custom ERP or system, KGRN's integration works alongside them, not around them.

How the Two Teams Work Together

Your developers and KGRN focus on different things, so nothing overlaps or falls through the cracks.

Your internal team keeps owning and maintaining your core system

KGRN handles ASP registration, PINT AE conversion, and Peppol connectivity

API documentation and technical support are provided directly to your developers

No need to expose your system's source code or infrastructure beyond the API connection

One connection method. Any system. Zero fragmented vendors.

Common questions from custom & in-house teams

Common Challenges for Custom & In-House Systems, Solved

What usually slows down businesses without a named ERP — and how KGRN removes the blocker.

The challenge

Your system doesn't have any existing integration documentation or connector.

How KGRN solves it

KGRN's technical team works directly with you to map your system's data structure, rather than relying on a pre-built connector that doesn't exist for custom systems.

The challenge

Master data inconsistencies risk delaying go-live.

How KGRN solves it

Data cleansing corrects TRNs, addresses and reference codes before they become integration blockers.

The challenge

Different entities run different systems, or no system at all.

How KGRN solves it

KGRN's middleware supports mixed environments, so each entity connects through whichever method fits it: ERP integration, API, or structured upload.

The challenge

Your internal team doesn't have spare capacity to build this from scratch.

How KGRN solves it

KGRN's implementation team builds and manages the integration directly, so your developers only need to support the connection, not build the compliance logic themselves.

The challenge

Uncertainty about how VAT treatment applies inside invoice data.

How KGRN solves it

Chartered accountants validate VAT logic against each invoice scenario, not just schema formatting.

Implementation

How Your ERP or Accounting Software Gets Connected

Frequently asked

Get Clarity Before eInvoicing Goes Live

Does KGRN support custom-built or in-house ERPs? +

Yes. KGRN's ASP middleware connects to custom-built and in-house ERPs through the same API and integration approach used for named ERPs, without requiring you to rebuild or expose your system's internals.

What if my business has no ERP or accounting software at all? +

KGRN offers a structured upload path for businesses without a full ERP: invoices are submitted through a pre-formatted sheet covering all mandatory PINT AE fields, and the platform validates, converts, and transmits them. You can move to API or ERP integration later without re-onboarding.

What's the difference between ERP Integration, Direct API Access, and Structured Upload? +

ERP Integration connects directly into an existing ERP or accounting platform. Direct API Access suits businesses without a full ERP whose developers want to connect once and automate submission. Structured Upload is a practical starting point for lower-volume businesses, using a pre-formatted sheet instead of a live integration.

Can KGRN connect to legacy or proprietary systems? +

Yes. Legacy and proprietary systems can connect through structured data exports mapped into the required PINT AE schema, or through the same API and middleware approach used for modern systems.

What is the 5-corner model? +

It's the Peppol-based exchange model the UAE has adopted, where an invoice moves from your ASP to your customer's ASP, with tax data reported to the FTA in parallel.

When does UAE eInvoicing apply to SME businesses without a named ERP? +

Most SMEs fall under the Phase 2 go-live from July 2027, after large businesses go live in January 2027. Exact timing depends on annual revenue, so smaller businesses typically have more runway, but should still appoint an ASP and test early.

Will KGRN work with my in-house IT or development team? +

Yes. KGRN's integration works alongside your existing in-house team rather than around them, providing API documentation and direct technical support while your team keeps ownership of your core system.

What does the free readiness check include for a custom or in-house system? +

A review of your current invoicing process, whatever system or method you use, mandatory field readiness, VAT logic, and a recommended connection path, before you commit to implementation.

Does KGRN provide support after go-live? +

Yes. Support continues through connectivity monitoring, VAT reconciliation, data health checks, and fully managed operations for businesses that want KGRN to run day-to-day compliance.

What happens if my business misses the ASP appointment deadline? +

Missing the deadline reduces the time available for integration, testing and UAT before the mandatory go-live date, increasing the risk of disruption at launch.
