Key Capabilities

Manage Invoice Books with Confidence

Set up and maintain GUI prefixes and number ranges by period. Business Central tracks usage automatically and helps prevent gaps or duplicate numbers.

Integrated E‑Invoice Uploads

You can transmit invoice data directly to the E‑Invoice Integration Platform by using Value‑Added Center (VAC) or Turnkey connections. This removes the need for manual re‑entry.

Seamless Business Central Integration

Generate GUI records automatically from Sales Orders or Posted Sales Invoices. All tax information is linked to the original accounting entries to support clear audit trails and easier reconciliation.

VAT Media File Generation

Create the required files for bi‑monthly VAT declarations with a single click. This reduces reporting time and improves accuracy.

This app helps your finance and accounting teams save time, reduce errors, and stay compliant with Taiwan’s tax regulations so your organization can stay focused on running the business.
