e-CF electronic invoicing: meet DGII requirements without disrupting your operation

We guide you through the entire process required by Ley 32-23, from the digital certificate to issuing in production, so certification never becomes your team's problem.

View all services

Ley 32-23 requires Dominican taxpayers to issue electronic tax receipts (e-CF) instead of paper NCF. The DGII rolls this out by taxpayer category: Large National Taxpayers passed their deadline in May 2024, and Large Local and Medium-sized taxpayers in November 2025. The only window still open is for Small, Micro and Unclassified taxpayers, which closes on November 15, 2026 after the extension granted in DGII Aviso Informativo 06-26.

Getting certified is not just installing software. You need a digital certificate, a formal application to become an electronic issuer, authorized sequences configured, an approved test set in the DGII certification environment, and a sworn statement before you can issue in production. We handle both the paperwork and the technical side so you can keep invoicing.

What this service includes

e-CF readiness assessment

We review your taxpayer category, your standing with the DGII, the system you use today, and your receipt volume to map the shortest path to certification.

Digital certificate and electronic issuer application

We guide you through obtaining the digital certificate for tax procedures — the P12 file issued by a certification authority accredited by INDOTEL — and filing the Emisor Electrónico application through the DGII's Oficina Virtual.

Issuer configuration

We set up the system that will issue your receipts: DGII-authorized sequences, the right e-CF type for each customer profile, and XML digital signing.

Test set and certification environment

In the certification environment we run and correct the DGII test set — over thirty use cases, including the electronic consumer-invoice summaries — until it is fully approved.

Go-live in production

We support the sworn statement and the resolution authorizing you as an electronic issuer, and monitor your first real submissions closely.

Post-certification support

We handle rejections, credit and debit notes, contingencies, and regulatory changes after go-live, which is when most questions actually appear.

Benefits for your business

  • Compliance on time

    You avoid penalties and the risk of being unable to issue fiscally valid receipts once your category's deadline arrives.

  • Less administrative load

    e-CF removes printing, physical filing, and manual receipt entry, cutting repetitive work for your accounting team.

  • Cleaner tax data

    The 606, 607, and 608 report formats come out more consistent and need fewer corrections, because the data is structured from the moment of issue.

  • Faster collections

    Your customer receives a valid receipt at the moment of the transaction, with no wait for a physical document.

  • A single point of responsibility

    We cover both the DGII paperwork and the technical configuration, instead of leaving you to coordinate several vendors.

How we work

  1. Assessment

    We map your current tax and technical situation and tell you plainly what is missing and how much effort it takes.

  2. Prerequisites

    We line up what the DGII requires before you start: active RNC, receipt authorization, digital certificate, and tax obligations up to date.

  3. Technical configuration

    We get the issuing system ready: receipt types, sequences, XML signing, and transmission to the DGII.

  4. Certification with the DGII

    We run the test set, fix rejections, and carry the process through to the authorization resolution.

  5. Production and follow-up

    We supervise your first real submissions and stay available for issues during the first billing cycles.

Who this is for

This service is for Small, Micro and Unclassified taxpayers who are not yet issuing e-CF and still have their window open. We also work with large and medium-sized taxpayers who have been required to comply since November 2025 and have not finished certifying, and with certified companies that need support to operate without rejections.

Why choose CoreTech

We have taken Dominican clients through the full e-CF certification process to issuing in production with the DGII, so we know where the paperwork stalls and which rejections show up in the test set. We handle the DGII filing and the technical configuration under one point of responsibility, in language that works for both accounting and IT.

Frequently asked questions

It depends on your taxpayer category. Large National Taxpayers have been required to comply since May 15, 2024, and Large Local and Medium-sized taxpayers since November 15, 2025 — if you fall in either group, your deadline has already passed. For Small, Micro and Unclassified taxpayers the deadline is November 15, 2026, after the six-month extension the DGII granted automatically and across the board through Aviso Informativo 06-26. Dates verified against the DGII on September 11, 2026. We confirm your group during the assessment, because the category is assigned by the DGII and does not always match the size a company assumes it is.

An active RNC, valid authorization to issue tax receipts, a digital certificate for tax procedures from a certifying authority, tax obligations up to date, and software capable of issuing e-CF. If any of that is missing, sorting it out is part of the engagement.

Based on our experience and what the DGII publishes, it usually takes two to six weeks, depending on how quickly the DGII responds at each stage and how prepared the company is. We cannot guarantee a timeline: the final resolution is issued by the DGII, not by us. That is why it pays to start with margin.

In many cases, yes. We assess whether your system can generate and sign the XML in the structure the DGII requires, or whether it is better to integrate it with a platform that already does. If there is no reasonable path, we say so in the assessment rather than force the integration.

Receipts issued outside the electronic scheme lose fiscal validity, and non-compliance can carry penalties of up to 50 minimum salaries. In practice the bigger risk is operational: being unable to invoice customers who do require an electronic receipt.

They are frequently confused and they are not the same. The e-CF is the document: the signed XML transmitted to the DGII. The e-NCF is the number identifying it — an eleven-character sequence starting with the letter E, then two digits for the receipt type and eight more of running numbering. Put simply: the e-NCF sits inside the e-CF, just as the NCF was printed inside the paper invoice.

For low volume with no need to integrate anything, yes — it is free and it complies. The limits show up as you grow. It does not integrate with your system, so every receipt is keyed in by hand; it does not produce the 606, 607 or IT-1 filings; and it caps the number of receipts per month. If you invoice from an ERP, a point of sale or your own system, the sensible path is integrating that system rather than duplicating data entry.

Yes. Issuing electronically does not remove the reporting obligation. What changes is data quality: because the information is structured from the moment of issuance, the 606, 607 and 608 filings come out more consistent and need fewer corrections. It is worth reviewing the first filing after go-live, since that is where mismatches between what was issued and what was reported tend to surface.

Regulation provides for contingency: you keep operating and the receipts are transmitted once the service is restored. What matters is that the system is built to queue and retry rather than stop invoicing, and that someone watches the queue. It is one of the points we configure and document before go-live.

An e-CF is a tax receipt in XML format, signed with a digital certificate and transmitted to the DGII for validation. A traditional NCF is a paper document with an authorized number sequence. The e-CF keeps the same fiscal value but no longer depends on printing and physical filing.
