EFRIS, done for you
inside WhatsApp.
Nexa is an AI assistant that lets Ugandan businesses issue fiscal invoices, receipts, credit notes and more — straight from a WhatsApp chat. No new app. No portal. No training.
EFRIS compliance shouldn’t stop you from selling.
Every VAT-registered business in Uganda must fiscalise its invoices through URA’s EFRIS. For most traders that means clunky portals, desktop software, or hiring someone just to keep up. Nexa removes all of it.
Logging into EFRIS or desktop software mid-sale kills momentum — and often needs a computer you don't have nearby.
Keeping every invoice, credit note and receipt fiscalised correctly is a real burden for small teams.
New software means installs, training and support. WhatsApp is already on every phone you own.
Live in three messages.
Save the Nexa number and send a message. Nothing to download, nothing to install.
Securely link your URA EFRIS credentials once. Nexa handles the rest from then on.
Invoice, issue receipts and manage stock in plain language — Nexa fiscalises with URA instantly.
Your whole EFRIS workflow, in chat.
Generate URA-compliant fiscal invoices with FDN and QR code in seconds, right in chat.
Issue and reconcile adjustments and returns without ever leaving WhatsApp.
Register and update stock items and keep them synced with EFRIS as you sell.
Automatically send fiscal receipts and QR codes to your customers on WhatsApp.
Every transaction is logged and exportable, so filing season is no longer a scramble.
Powered by AI — type or send a voice note in plain English. No forms, no menus.
Questions, answered.
