A high-volume enterprise invoicing operator needed a robust system to issue electronic tax receipts (e-CF) and submit them directly to the Dominican tax authority. We delivered an enterprise-grade .NET 8 backend with workers and an operations portal that automate the entire pipeline — issuance, digital signature, submission and reporting — with structured logging into SQL Server.

Manual e-CF processes were a bottleneck for a high-volume operator that could not afford rejected receipts or non-compliance.
Manual workflows could not keep up with daily transactions while staying compliant.
Any deviation in the e-CF format meant rejected receipts and operational rework.
Accounting teams were absorbing repetitive work that should run unattended.
We engineered an end-to-end enterprise backend on .NET that owns the full e-CF lifecycle and is observable from a control panel.
Receipts generated programmatically from upstream business events.
Signing keys managed securely and applied automatically to every receipt.
Native integration with the tax authority's API with retries and traceability.
Operational dashboard for monitoring submissions, rejections and tax reports.
The platform automates the full invoicing process and removes a major source of operational risk for the finance team.
