This is the Codeblix onboarding guide for connecting a Mauritius Economic Operator to the MRA e-Invoicing Secure Hub. It explains who signs in, the two ways Codeblix can be authorised, what company information is required and how the setup moves from TEST to LIVE.

Economic Operator access comes first

The company registers or signs in on the official MRA e-Invoicing Secure Hub Portal using its TAN and MRA e-Services password. This portal access belongs to the Economic Operator and is separate from the Transmission User/API credentials used by the EBS.

Choose how Codeblix will be authorised

For managed onboarding, the company securely provides its Economic Operator TAN and portal password so Codeblix can complete the portal steps. For assisted onboarding, the company signs in and adds Codeblix as the Test User using identity details supplied privately at the start of onboarding. The assisted route requires the company contact to stay available for verification and approvals.

Keep each onboarding state separate

Economic Operator registration, Test User access, Transmission User credentials, TEST verification, LIVE activation and successful invoice fiscalisation are separate states. Codeblix checks each state before moving to the next and does not treat portal registration alone as proof that the EBS is ready for production.

How the MRA Portal integration works

The MRA Portal integration is built into Codeblix. There is no separate plugin, no third-party middleware, and no annual licence. You connect your MRA Portal account from the Integrations screen, authorise Codeblix to access your data, and the sync runs in the background.

Two-way sync means data flows both ways. When you create a record in Codeblix, it appears in MRA Portal. When something changes in MRA Portal, it reflects in Codeblix. No double entry, no copy-paste, no CSV exports.

Economic Operator onboarding

MRA e-Invoicing Secure Hub onboarding with Codeblix

Start by registering or signing in as an Economic Operator with the company TAN and MRA e-Services password. You can then choose one of two onboarding routes: let Codeblix manage the portal process, or add Codeblix as a Test User and work through the checks with us.

On the MRA Secure Hub home page, use the Economic Operator section highlighted in the screenshot. Open the official MRA Secure Hub Portal.
Option 1 - Managed onboarding

Let Codeblix handle the full portal process

Provide the company TAN and Economic Operator portal password through the secure one-time sharing method arranged during onboarding. Codeblix will handle the Secure Hub registration or sign-in, Test User setup, verification, Transmission User/API credential setup, EBS connection testing and the move from TEST to LIVE.

The company contact may still need to respond to an MRA verification, one-time code or approval request if the portal asks for it.

Credential safety: do not send a portal password through the public contact form, ordinary email or an open chat. We will arrange a private one-time transfer method.
Option 2 - Assisted onboarding

Add Codeblix as the Test User

Register or sign in as an Economic Operator, then add Codeblix as the Test User. We provide the authorised person's identity and contact information privately when onboarding starts.

This route needs active back-and-forth with your team for portal screens, verification and approvals. Please keep the company contact available for a few hours on the agreed onboarding day so the process does not stall.

Information checklist

Company details to send Codeblix

We use these details to create the correct company workspace, seller identity and onboarding record.

  • Company legal name
  • Business Registration Number (BRN)
  • Tax Account Number (TAN)
  • VAT number
  • Registered business address
  • Contact person name
  • Email address
  • Mobile number
Separate credentials

Transmission User and API access

The Economic Operator login opens the company portal. The Transmission User/API credentials are separate and allow the configured EBS to communicate with the MRA e-Invoicing service.

If the Transmission User credentials are created or received on your side, they must also be shared with Codeblix through the agreed secure method. We test them in the correct MRA environment before any LIVE activation.

Final production check

Validate 1-2 real invoices after LIVE activation

After TEST checks pass and the MRA setup is switched to LIVE, Codeblix and the client will fiscalise one or two genuine business invoices. We verify the legal seller details, customer data, items, VAT treatment, totals, payment/account mappings, MRA result, QR code and final customer PDF before normal daily use.

These are real fiscal records, so the client must approve the invoices and their source data before submission. Any correction follows the proper fiscal-document process.

FAQ

What are the two ways Codeblix can onboard my company?

You can securely give Codeblix the Economic Operator TAN and portal password so we manage the process, or you can sign in yourself and add Codeblix as the Test User. The assisted route needs your attention for portal screens, verification and approvals.

Will Codeblix publish its Test User identity details on this page?

No. The authorised person's name, NID, mobile number and email are provided privately when onboarding starts. The public Test User label is Codeblix.

Do I also need to share the Transmission User/API credentials?

Yes, if those credentials are created or received on your side. They are separate from the Economic Operator login and must be transferred using the secure method agreed with Codeblix.

Why are 1-2 real invoices fiscalised after LIVE activation?

The controlled LIVE check confirms the legal seller, customer, item, VAT, total, payment and account mappings, MRA response, QR code and final customer PDF before normal daily use. The client approves these genuine invoices before submission.

When will users receive their Codeblix login details?

Codeblix login details are issued to authorised users after onboarding, company configuration and access checks are complete.
