AVS EIS – E-Invoicing System

Connect Your Existing Software to UAE E-Invoicing

AVS EIS helps businesses prepare, validate, transform, send, receive, monitor and archive electronic invoices through one central platform.

Connect your existing ERP or accounting software to your appointed UAE Accredited Service Provider without necessarily replacing the systems you already use.

What Is AVS EIS

AVS EIS is an e-invoicing preparation, integration and management platform connecting your existing business systems with your appointed UAE Accredited Service Provider.

It checks invoice data, prepares the required PINT AE format, submits documents through the appointed ASP and displays their processing status. It also collects supplier e-invoices for checking, approval or dispute.

Regulated Peppol exchange and tax-data reporting to the Federal Tax Authority are performed through the appointed Accredited Service Provider.

What AVS EIS Can Do

Prepare sales invoices and credit notes
Perform more than 35 validation checks
Generate PINT AE XML
Submit documents through the appointed ASP
Receive and check supplier e-invoices
Identify TRN, duplicate, VAT and total-related issues
Track document status and usage
Support invoice approval and dispute workflows
Maintain a secure archive and complete audit trail
Produce sales and purchase reports

Flexible Connectivity Options

AVS EIS can receive invoice information through:

Direct API connection
Database connection
Push from the client’s ERP
Webhooks
Watch folders
Excel and CSV imports
PDFs and scanned documents
Manual web-portal entry

This makes the platform suitable for businesses using cloud-based, on-premise, customised or legacy systems. The final connectivity method, mapping requirements and integration scope will be confirmed following a technical assessment.

How It Works

Create or Import

Prepare the invoice in your ERP, accounting software, Excel file, PDF or AVS EIS web portal.

Validate and Convert

AVS EIS checks the invoice information and prepares the required PINT AE structured format.

Submit Through Your ASP

The invoice is submitted to the appointed Accredited Service Provider for validation, Peppol exchange and tax-data reporting.

Monitor the Result

Track whether the document is ready, submitted, delivered, completed or rejected.

Standard API access does not automatically include development or modification within the client’s ERP. ERP-side work and custom data transformation must be assessed and agreed separately.

Manage Supplier E-Invoices

Supplier e-invoices received through the appointed ASP can be automatically collected and checked for:

Supplier TRN
Correct recipient information
Duplicate invoices
Invoice totals and VAT
Due-date information

Users can approve, review or dispute an invoice. Approved documents can then be exported or returned to the accounting system through the agreed integration method.

Implementation Support

Our implementation process includes:

Initial consultation
Readiness and system assessment
Connectivity and solution selection
ASP onboarding and integration coordination
Testing and user training
Go-live support

AVS EIS includes a structured test pack with 11 standard scenarios to help identify data and connectivity issues before live implementation.

Frequently Asked Questions

Do we need to replace our existing ERP?

Not necessarily. AVS EIS can connect through APIs, databases, webhooks, files, watch folders or the web portal, depending on system compatibility.

Is a PDF considered an e-invoice?

No. An e-invoice must contain structured data. AVS EIS can extract information from eligible PDFs and prepare it for review and conversion.

Does AVS EIS report directly to the FTA?

No. AVS EIS prepares, validates and manages the invoice data. The appointed Accredited Service Provider performs regulated Peppol exchange and tax-data reporting.

Is ERP integration automatically included?

No. Integration depends on the ERP, data structure and technical requirements. Custom development and data mapping will be assessed separately.
