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.
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, and for micro, small, and medium-sized businesses, unclassified taxpayers, and independent professionals the current deadline is November 15, 2026.
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 and filing the electronic issuer application through the 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
We run and correct the test set the DGII requires, including 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.

Who this is for
This service is for micro, small, and medium-sized businesses, unclassified taxpayers, and independent professionals who are not yet issuing e-CF and still have a deadline ahead. We also work with large and medium taxpayers who are already required to comply but 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.
