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.
