Factura DGII — Dominican Republic Tax Invoice Generator
Local-first, privacy-focused fiscal invoice generator for DGII NCF & e-NCF compliance
Project Overview
Factura DGII is a high-speed, privacy-first web application designed for Dominican Republic freelancers, contractors, and small businesses to issue compliant NCF fiscal tax invoices with automated ITBIS calculations and instant PDF rendering.
The Challenge
Issuing compliant tax invoices (Comprobantes Fiscales NCF) in the Dominican Republic traditionally requires cumbersome software, subscription fees, or invasive data collection. Users needed a lightweight, accessible tool to quickly draft NCF-compliant invoices without storing sensitive client billing data on remote SaaS servers.
Technical Constraints
The tool had to strictly adhere to DGII NCF sequence validation rules (B01, B02, B14, B15, e-NCF), calculate 18% ITBIS tax and retention percentages deterministically, and generate high-density printable vector PDFs entirely inside client browser memory.
Technologies & Architecture Stack
Local-First Architecture & Vector Compilation Pipeline
We engineered a lightweight Next.js application that runs entirely client-side without external database calls or user tracking:
Key Measurable Outcomes
- Sub-10ms invoice compilation and instant vector PDF rendering.
- 100% privacy guarantee with zero server tracking or database logs.
- Flawless DGII NCF sequence compliance across all standard tax types.
