The deadline

November 2026 is the deadline

November 1, 2026

They may issue only electronic tax documents. Their paper B sequences expire on October 31, 2026.

Small, micro, and unclassified taxpayers

November 15, 2026

Date resulting from the six-month general extension granted by DGII on May 6, 2026.

The right position

Your ERP keeps the sale; Timbro resolves the fiscal cycle

The ERP keeps the customer master, prices, and business accounting

Timbro does not replace the sales system: it runs the fiscal cycle and returns a status the ERP records once

05

Integration

One integration, all 10 e-CF types

API REST

Public OpenAPI contract

SDK

Client ready to consume the API

Webhooks

Signed and deduplicated

Idempotency

Idempotency-Key on every write

Separate environments

Separate credentials for testing and production

Public documentation

Spanish and English, open online

timbro.do/docs
Timbro public documentation with onboarding, idempotency, webhooks, errors, recovery, and fiscal delivery guides

06

Numbering

You decide who assigns the e-NCF

External assignment

The ERP keeps its numbering

It sends the e-NCF; Timbro validates its structure, type, uniqueness, and membership in the range before processing the operation

Central assignment

Timbro assigns the sequence

Takes a number from an authorized range in the same transaction that accepts the operation, with no intermediate steps

Distributed assignment

One sequence per system

Each system receives a reserved range to operate without collisions across locations

Scope by RNC, e-CF type, and environment

Expiry and remaining capacity visible

Assignment confirmed in one transaction

Timbro records DGII authorizations and assigns sequences within authorized ranges

Two operations never share a number, whichever model you choose

07

Signing and custody

Your signing stays under your control

Signing in your environment

The certificate remains under your business's control

Timbro signs from the infrastructure agreed for your operation, with access and responsibilities defined in the proposal

The implementation protects the certificate and limits its use to authorized signing operations

Compatibility

Works with certificates accepted for your tax operations

Separation by issuer

Each business, location, and environment keeps its own configuration

Restricted access

Only authorized staff manage signing

Verifiable evidence

Each signature is associated with the corresponding certificate

08

Operations and locations

An implementation defined for each location

Distributed fiscal identity

BusinessRNCLocationSystemEnvironment

Five distinct levels, so no location shares certificates or sequences indiscriminately

The Local proposal defines where each function operates and the responsibilities of Timbro and the business

Timbro Local

Control in your infrastructure

The implementation places signing and the agreed components in the environment named by the business

Scope by location the proposal identifies the functions included in each implementation

Agreed service any support, continuity, or recovery commitment applies only when stated in the signed order

09

Lifecycle

Every invoice has a verifiable history

  1. 1

    The request is accepted once, even if repeated

  2. 2

    Each stage has an explicit status

  3. 3

    Retries and uncertain results are resolved through retrieval and reconciliation

  4. 4

    Recovery returns the document; it never issues another

An uncertain result is clarified by retrieving status, never by issuing again

Evidence per operation

  • What was received
  • What number was assigned
  • Which certificate signed
  • What was sent
  • What DGII answered
  • What remains pending

Delivery and retention

Your customer finds their invoices in Cuenta Timbro, and you do not manage storage

Delivery

Email with delivery statuses, XML and printed representation downloads, and a Timbro account where the recipient can find invoices

Retention

We retain your invoices and their evidence for 10 years, so the business does not manage storage

An issued document is not edited: the accounting correction is a credit note

Purchase details with invoice in Timbro account
Approved payment with the invoice still pending DGII

11

Responsibilities

What Timbro handles for you

10-year retention

Invoices and their evidence remain available without managing storage

Sequences with Timbro or the ERP

Numbering runs where it suits the business, with the same controls

Regulatory changes absorbed

Timbro keeps up with DGII changes to format and communication

Actionable statuses

Each response explains what happened and what your team should do

Delivery to the recipient

Email, document download, and a Timbro account for the invoice recipient

Evidence and recovery

Every operation can be reconstructed and none is issued twice
