Commerce and payments
Plan the full Vietnam transaction, including failure and reconciliation.
VND, foreign-contractor and e-commerce tax, invoices, payment providers, hosting, content, platform, and licensing requirements depend on the actual service.
What the build must distinguish
A payment screen is only one part of the transaction.
Display currency, contract currency, settlement, provider eligibility, authentication, invoice evidence, refunds, tax responsibility, and reconciliation are separate decisions. The client and its advisers confirm the commercial model; the software implements the agreed behavior.
- Confirm seller, customer, and place-of-supply facts
- Classify custom work, SaaS, automated service, and support
- Use client-owned payment and identity providers approved for the parties
- Design retries, pending states, receipts, refunds, and duplicate protection
- Reconcile provider records against the system of record
- Complete sanctions or export-control screening where applicable
A country guide does not guarantee a payment route.
Availability can change by bank, card, currency, customer identity, service type, and provider policy. The proposed route must be verified before a paid engagement tied to Vietnam is accepted.

A useful first conversation covers the users, existing systems, language responsibility, data, payments, timing, and the evidence that will count as done in Vietnam.
