DGI Integration · Democratic Republic of Congo

Connect Your Business Software to DGI

Voyager IT provides enterprise DGI e-invoicing integration for ERP, POS, billing, accounting and custom business applications — connecting your SFE to the e-MCF so every invoice is certified by the Direction Générale des Impôts (DGI) and issued as a facture normalisée, without replacing the systems you already use.

Keep what works

Keep the System You Already Trust

Most established businesses in the DRC have years of investment behind their software — an ERP rollout, a POS estate across branches, an accounting platform their finance team knows well, or a billing application built specifically for how they trade. That investment is not something to write off.

DGI requirements should not force you to rebuild your technology environment. Voyager IT provides the integration layer that extends your existing system toward DGI connectivity, so your operations, your data and your team's day-to-day workflow stay where they are.

No unnecessary ERP replacement. No unnecessary business disruption.

What actually changes

What Happens When You Issue an Invoice

Under the DGI specification, a compliant invoicing system obtains security elements from the DGI control module and prints them on the invoice. No invoice can be recorded without them. That round trip is the requirement placed on every compliant system in the DRC — here is how it looks from your side of the counter.

01 Your side

The sale is recorded

Your cashier, sales team or billing clerk raises the invoice in the system they already use. Nothing about their screen or routine changes.

02 Your side

The invoice data is submitted

The invoicing data is passed to the DGI control module for certification. This happens behind the scenes as part of issuing the invoice.

03 DGI side

Security elements are returned

DGI returns the security elements that prove the invoice is authentic and unaltered, together with the data needed for the QR code.

04 Your side

The compliant invoice is issued

The invoice prints or sends carrying those security elements and a scannable QR code — in the format shown below.

This sequence is the behaviour the DGI specification requires of any compliant invoicing system, and is published by the authority. How Voyager IT delivers it inside your environment is proprietary and is not described here.

The invoice format

Your Invoice, DGI-Ready

The commercial document your customer receives keeps your layout, your branding and your terms. What integration adds is the fiscal block — the identifiers, security elements and QR code the DGI specification requires.

Requirements are drawn from the DGI specification for compliant invoicing systems; the exact presentation depends on your business, your document template and your tax regime.

Why Voyager IT

An Integration Team, Not a Software Replacement Project

DGI integration sits between two things that both have to keep working: the software your business runs on, and the fiscal environment it has to reach. That is integration work, and it is what we do.

Enterprise integration expertise

Connecting business systems that were never originally designed to talk to each other.

ERP & POS experience

Practical familiarity with how ERP and point-of-sale environments actually run in trading businesses.

Business Central & LS Central

Established delivery experience across Microsoft Dynamics 365 Business Central and LS Central.

API & middleware engineering

An engineering team whose core discipline is building reliable connections between platforms.

Custom software integration

Comfortable with in-house and legacy applications, including those without standard documentation.

Retail & business applications

Background in retail, distribution and commercial software, including our own POS product.

We work with your systems

We start from the environment you already have — and, where you want, alongside your current vendor.

Implementation & support

Involved through deployment and available afterwards for ongoing integration requirements.

For ERP, POS & software vendors

Add DGI Capability to Your Software Without Building It From Scratch

If you sell or maintain software used by businesses in the DRC, your customers are asking you about DGI. Building that capability in-house is a project in itself — one that sits outside the roadmap you actually want to be delivering.

ERP vendors, POS companies, software developers and system integrators can work with Voyager IT to bring DGI integration to their own customers, under a commercial arrangement that fits how you go to market.

Frequently asked

DGI Integration Questions

What is the DGI (Direction Générale des Impôts)?
The Direction Générale des Impôts — the DGI — is the tax authority of the Democratic Republic of Congo, responsible for administering taxation and for the facture normalisée reform. It publishes the SFE specification that your invoicing system has to meet, and it operates the environment your invoices are certified against. Voyager IT builds the integration that connects the software you already run to it.
What is the SFE (Système de Facturation Électronique)?
The SFE — Système de Facturation Électronique — is the electronic invoicing system a business uses to issue invoices in the DRC, whether that is commercial software, an in-house application or a device. Under the DGI framework it has to meet the SFE specification and communicate with a fiscal control module so that every invoice is certified before it reaches your customer. In practice the ERP, POS or billing system you already run is what becomes your SFE, and Voyager IT builds the integration that makes it conform.
What is an e-MCF (Module de Contrôle Fiscal), and do we need one?
The MCF — Module de Contrôle Fiscal — is the fiscal control module that certifies each invoice with the DGI and returns the security elements printed on it. It exists as a physical electronic tax device and as the e-MCF, its electronic equivalent. Your SFE has to communicate with it, keep it synchronised with the DGI, and warn users when it has not reached the DGI for more than seven days. Voyager IT builds and operates that communication layer for you.
Is la facture normalisée (FACNO) the same as DGI e-invoicing?
They describe the same obligation from two angles. La facture normalisée — FACNO — is the standardised invoice that DRC regulations require, and DGI e-invoicing is the electronic process that certifies it through the SFE and the MCF. Voyager IT covers both sides: the mandatory content the invoice must carry, and the certification round trip with the DGI.
Does our invoicing software need SFE certification from the DGI?
Software intended to issue standardised invoices goes through a DGI conformity process, where a declaration of conformity is assessed against the SFE requirement tables alongside functional testing before registration. Suppliers who intend to commercialise an SFE and taxpayers using their own system are treated differently. Voyager IT works with you through that review and builds the integration to match what the specification asks for.
Can you integrate our existing ERP with DGI?
In most cases, yes. Voyager IT's DGI integration is designed to be ERP-agnostic, and we have delivered integration work across global platforms, industry-specific software and in-house applications. The starting point is always a short assessment of your environment, after which we can confirm the approach and effort involved.
Do we need to replace our current ERP?
No. That is the central idea behind this offering. You keep the ERP, POS or billing system your business already runs on, and Voyager IT provides the integration capability that connects it to DGI. We are not asking you to migrate platforms, and we do not require you to adopt any particular product to proceed.
Can you integrate custom or internally developed software?
Yes. Custom-built ERP systems, in-house billing applications, web applications and older legacy systems are a normal part of this work. Where documentation is thin or the original developers have moved on, that becomes part of what the initial assessment covers.
Can you integrate our existing POS?
Yes. Retail, supermarket, pharmacy, restaurant and hospitality point-of-sale environments are among the most common cases we are asked about. The objective is always to leave store operations and the cashier experience working the way your staff already know.
Can you work with SAP, Business Central, LS Central, Odoo, Oracle or Sage?
These are among the platforms we are regularly asked about, and Voyager IT has particular delivery depth in Microsoft Dynamics 365 Business Central and LS Central. Scope and effort depend on your specific version, configuration and customisations, which we confirm during the assessment.
Can you work with our current ERP vendor or IT partner?
Yes, and it is often the most efficient route. Your existing vendor knows your configuration and your business rules. Voyager IT is comfortable working alongside an incumbent partner, or dealing directly with your internal IT team — whichever arrangement you prefer.
Can multiple branches be integrated?
Yes. Multi-branch retail networks, distribution operations and enterprise groups with several locations are within scope, including organisations where different sites run different software. Rollout sequencing across branches is agreed with you as part of planning.
Can Voyager IT integrate an internally developed billing system?
Yes. A billing application written specifically for how your business trades is a well-suited candidate, because it usually already reflects your commercial rules accurately. We assess it the same way we would a commercial platform.
Can software companies partner with Voyager IT?
Yes. ERP vendors, POS companies, software developers and system integrators can work with Voyager IT to offer DGI integration to their own customers rather than building the capability internally. Several engagement models are possible, agreed case by case. Write to partnership@voyageritnepal.com to open the conversation.
What will our invoice actually look like after DGI integration?
It keeps your layout, branding and commercial terms. What integration adds is the fiscal block the DGI specification requires — the security elements returned by DGI, your system identifier and a scannable QR code — alongside the mandatory commercial details such as NIF, taxation groups, totals per group, the total in words and the USD equivalent. There is an annotated specimen further up this page.
Will our staff have to work differently at the counter?
The intention is no. Your team raises the invoice in the system they already use; the certification round trip with DGI happens as part of issuing the invoice rather than as a separate task. Where a business process genuinely has to change to satisfy a requirement, we identify it during the assessment so there are no surprises at go-live.
How do we start a DGI integration project?
Tell us what system your organisation currently uses and roughly how you invoice today. Voyager IT will review the environment, discuss the right approach with you, and set out scope, timeline and commercial terms before any work is committed.
