Questions fréquentes
What is automated e-tax invoice batch-generation?
It is a financial technology solution that automatically converts sales transactions from e-commerce platforms into legally compliant e-Tax invoices in XML and PDF formats. These documents are electronically signed and transmitted directly to the Revenue Department and customers without manual intervention.
How does the Revenue Department Host-to-Host system work?
The Host-to-Host system is a direct server-to-server connection established between an enterprise's financial network and the Revenue Department's database. It allows secure, high-speed transfers of large batches of cryptographic tax invoices, making it perfect for high-volume retail operations.
How much money can a business save by automating its e-tax invoices?
By eliminating manual labor, paper, and physical shipping, businesses can expect significant savings. For example, Siam Direct reduced its invoice processing costs by 82% and saved approximately 140,000 THB per month in administrative and overtime labor costs.
What are the common integration pitfalls to avoid?
The biggest mistakes include failing to plan for database latency between your sales platform and ERP system, and not setting up an asynchronous message queue. Without these, your system may experience dropped connections and backlog bottlenecks during high-traffic shopping campaigns.
Is the digital e-tax invoice system safe for tax audits?
Yes, it is highly secure. Archiving signed XML files in immutable, cloud-based storage guarantees that files cannot be modified or deleted. This ensures 100% compliance and lets you easily retrieve any historical document to present to auditors during routine tax inspections.
