Issue e-invoice by integrating Viindoo with Viettel’s S-Invoice service¶
Nowadays, e-invoice has become a trend in digital transformation. E-invoices are integrated into enterprise management systems, accounting software, etc., helping to synchronize data, optimize usage time, and save printing, issuing, and storage costs for enterprises. For authority agencies, e-invoice plays an important role in managing trades transparently. To satisfy enterprises’ needs for managing e-invoices, Viindoo has integrated e-invoices into the Viindoo enterprise management system. Viindoo not only integrates e-invoices for VietNam enterprises but also supports e-invoice formats according to other countries’ standards with localization modules.
In this article, we will learn how to Integrate Viettel’s S-Invoice with Viindoo.
How to integrate with S-Invoice¶
Install the module¶
Enter Viindoo Apps, search for E-Invoice - Viettel S-Invoice on the search bar, and press Install.
Declare the integration information¶
After installing the E-Invoice - Viettel S-Invoice module, to declare the E-invoice information, navigate to Accounting > Configuration > E-invoice.
Follow the steps below to declare:
Step 1: E-Invoice services¶
Here, you will see two S-Invoice services supported by Viindoo.
The declaration process for the 2 versions is similar, the only difference is the API URL provided for your enterprise by Viettel.
S-Invoice v1’s API URL: https://demo-sinvoice.viettel.vn:8443/;
S-Invoice v2’s API URL: https://api-vinvoice.viettel.vn/services/einvoiceapplication/api/.
In this article, we will declare for the S-Invoice API v2 version, you can do the same for the S-Invoice API v1.
Note
The information you use to declare in the Viindoo system (e.g. user name, password, e-invoice’s serial, template, type, etc.), will be provided by the E-Invoice service provider.
The setting information in this article is only a reference for the test mode;
