KRA eTIMS VSCU Integration for Acumatica

Overview

The Kenya Revenue Authority's eTIMS (electronic Tax Invoice Management System) replaced the legacy ETR/TIMS regime with a fully digital, software-driven Virtual Sales Control Unit (VSCU). This integration plugs directly into Acumatica AR Invoices, Credit Memos, and Cash Sales so every document is signed, numbered, and transmitted to KRA before the sales clerk hits print.

Core Features

Real-time invoice transmission to KRA eTIMS (sandbox + production)
CU-invoice number & QR code stamped back onto the Acumatica document
Credit & debit notes linked to the original CU-invoice number
Automatic retry + offline queue for network interruptions
Per-branch device tagging and multi-branch configuration
Export of B2B, B2C, export, and exempt-rated sales
Cancellation & void handling in line with KRA rules
HSCode validation and stock movement logging

How It Works

1. Trigger

Acumatica Business Event fires on AR Invoice / Credit Memo release.

2. Transform

Custom graph projects Acumatica fields into KRA eTIMS payload (seller TIN, buyer TIN, line items, HSCode, VAT).

3. Sign

Payload is signed using the branch VSCU certificate & transmitted to the eTIMS API.

4. Persist

CU-invoice number & QR code written back to custom DAC fields; audit row inserted.

5. Print

Acumatica Report Designer prints the KRA-compliant invoice with QR stamp.

Best Fit

Retailers, distributors, manufacturers operating in Kenya
Businesses already on Acumatica wanting KRA compliance without swapping POS
Multi-branch operations needing one fiscalization layer across sites
