UAE E-Invoicing for Tally Prime — Desktop Agent Integration

TrustBill connects to Tally Prime via a lightweight desktop agent that watches your export folder. When you export invoices from Tally (Excel, CSV, or XML), the agent automatically uploads them to TrustBill, converts them to PINT-AE XML format, validates against FTA requirements, and submits to the accredited ASP network. The agent runs in the background with minimal system impact — no manual intervention required after initial setup.

This approach is ideal for Tally users who prefer their existing export workflows. You continue using Tally Prime exactly as you do today: create invoices, export to your preferred format, and the desktop agent handles the rest. The agent supports all Tally invoice types: sales invoices, credit notes, debit notes, and export invoices. It works with Tally Prime, Tally.ERP 9, and older versions.

Setting up the Tally Prime desktop agent takes less than 5 minutes:

1. **Create your TrustBill account** — Sign up for free (no credit card required). 2. **Download the desktop agent** — Get the Windows or macOS installer from your TrustBill dashboard. 3. **Install and configure** — Run the installer, enter your TrustBill credentials, and select your Tally export folder. 4. **Choose export format** — Select Excel, CSV, or XML as your preferred Tally export format. 5. **Test submission** — Export a test invoice from Tally and verify it appears in TrustBill with PINT-AE validation.

The desktop agent uses encrypted communication (TLS 1.3) and stores credentials locally on your machine. It runs as a background service and automatically checks for updates.

TrustBill automatically converts Tally exports to PINT-AE XML format, the UAE's national e-invoicing standard. The conversion handles all required data elements: invoice UUID, issue date, seller/buyer TRN, line-item details, VAT rates, and UAE-specific fields like free zone flags and margin scheme indicators.

Tally stores invoice data in its proprietary format, which differs from PINT-AE requirements. TrustBill's mapping engine transforms Tally export structures to PINT-AE specifications, ensuring every field is correctly populated. The system validates each converted invoice against the FTA's 51 mandatory data elements before submission, catching errors like missing TRNs, invalid VAT rates, or incomplete line-item details. Validation errors are reported in the TrustBill dashboard with clear explanations, allowing you to fix issues in Tally and re-export.
