e-lnvoicing in Vietnam is the national e-invoicing system under which every invoice Vietnam businesses issue must be an e-signed XML file and submitted to the General Department of Taxation (GDT). Invoices can be issued in two ways. With a tax authority code, wherein the GDT validates the invoice with a unique code before you send it to your customer. Without a code, wherein you send the signed invoice to your customer and report the data to the GDT.
Our Vietnam e-invoicing solution is a native add-on for Sage ERP users that makes e-invoicing efficient and accurate in line with GDT requirements. By automating end-to-end e-invoicing workflow, the solution ensures you are fully covered, including XML invoice generation, digital signing, service provider integration, data submission to the e-tax portal, GDT unique code capturing, and invoice status tracking.
Vietnam e-invoicing requires invoices to be created as digitally signed XML files and submitted to the General Department of Taxation for validation and reporting.

Is e-Invoicing mandatory in Vietnam?
Yes. All taxpayers must issue e-invoices, with limited exceptions. Paper invoices are no longer valid.
What is the difference between an invoice with code and without code?
With code, the seller sends the invoice data to the GDT, which issues a unique code, and then the invoice with code is sent to the buyer. Without code, the seller sends the invoice to the buyer and reports the invoice data to the GDT on the same day.
Do I need a service provider?
Yes. Invoice data is sent to the GDT through an authorized e-invoice service provider and the add-on connects Sage ERP to your provider. Vietnamese rules also allow businesses to send data directly to the GDT after applying through its portal.
Does Vietnam e-Invoicing for Sage X3 need a separate invoicing tool?
No. You do need a separate tool to enable e-invoicing for Sage X3 in Vietnam, as the whole process runs inside the ERP system. You only need an authorized service provider for GDT connectivity. We connect it to Sage X3 for you.
Can I use Vietnam e-Invoicing for Sage Intacct?
Yes. Vietnam e-Invoicing add-on is built for Sage Intacct. It converts Sage Intacct invoices into the required XML format, sends it to the GDT via the service provider, and updates the GDT code and invoice status in Sage Intacct.
Can I use Sage 300 e-Invoicing in Vietnam without changing my invoicing process?
Yes. You create invoices in Sage 300 as you do today, and the add-on handles the XML, digital signing, GDT submission, and status tracking.
