Vietnam E-Invoice Compliance for Business Central
A build-to-order AL extension that issues Vietnamese e-invoices straight from Dynamics 365 Business Central postings — provider API transmission, invoice code handling, tax mapping, rejection corrections and a compliant archive. ECOSIRE scopes, builds, installs and supports it; it is not an AppSource download.
- Setup page holding provider endpoint, credentials, environment (test/production) and invoice form and serial patterns, with secrets held in isolated storage rather than plain table fields
- Event-subscriber integration on the posting routines so transmission is enqueued after posting without blocking the user or holding a database lock
