In Progress

Engineered to transmit serialized tax invoices to the Inland Revenue Department Central Billing Monitoring System API. Certification currently in progress with govt authorities.

Nepali Lakhs & Crores Grouping

Numbers format cleanly in Nepali currency notation (e.g., Rs. 1,25,000.00 instead of 125,000.00) with automatic Nepali words conversion on printouts to prevent dispute and forgery.
