E-Invoice Software Vietnam 2026: Top Platforms Compared

Since July 1, 2022, every business and individual business household in Vietnam is required to use electronic invoices under Decree 123/2020/ND-CP. Paper invoices are officially a thing of the past. If you have not yet chosen an e-invoice platform, or you are unhappy with your current one, this guide compares the leading providers and walks you through a smooth transition.

Why E-Invoicing Matters for Every Vietnamese Business

E-invoicing is not just a legal obligation — it is a competitive advantage. Businesses that use e-invoices report 30-50% faster invoice processing, fewer data-entry errors, and easier tax filing. Here is what you gain:

• Legal compliance: Avoid fines of 1,000,000 to 2,000,000 VND per invoice for late or non-compliant issuance.
• Cost savings: No more printing, storing, or shipping paper invoices. Average savings: 500 VND per invoice.
• Faster accounting: Invoices are instantly available to your accountant or bookkeeper.
• Better audit readiness: Digital records with timestamps make tax audits straightforward.

MISA e-Invoice — The All-Rounder

MISA is the most widely used accounting and e-invoice platform in Vietnam. Its strength lies in the tight integration between invoicing, bookkeeping, and tax filing. The API allows you to connect MISA to your own ERP or POS system. MISA offers MISA SME.NET 2023 for small businesses and MISA ASP.NET for accounting firms managing multiple clients.

VNPT-Invoice — Government-Grade Reliability

Operated by Vietnam Posts and Telecommunications Group, VNPT-Invoice is trusted by large enterprises and government agencies. Its nationwide network of branches makes onboarding and support convenient even in remote provinces. VNPT also offers bundled packages with digital certificates (ch? k� s?).

Sapo & KiotViet — Best for Retail

If you run a retail store, coffee shop, or online shop, Sapo and KiotViet combine POS, inventory, and e-invoicing into a single subscription. This eliminates the need to juggle multiple systems and reduces training time for staff. Both platforms offer free tiers with limited invoices per month, making them ideal for startups.

What to Look for When Choosing E-Invoice Software

Not every business needs the same solution. Here are the key factors to evaluate:

1. Compliance: Confirm the provider is licensed by the General Department of Taxation and supports Decree 123 templates.
2. Integration: Can it connect to your existing POS, ERP, or accounting software via API?
3. Volume pricing: Check the cost per invoice above the base limit. High-volume sellers need transparent pricing.
4. Multi-branch support: Essential if you operate from multiple locations.
5. Digital certificate support: Ensure compatibility with your current ch? k� s? provider.
6. Customer support: Vietnamese-language support is critical. Check for live chat, phone, and on-site assistance.

Step-by-Step: How to Switch E-Invoice Providers

Switching providers is simpler than most business owners think. Follow these six steps:

1. Notify your current provider: Submit a written request to terminate the invoice template contract.
2. Complete pending invoices: Ensure all partially issued invoices are finalized before the switch.
3. Deregister with the tax authority: File form 01/�K-HDDT to remove the old invoice template.
4. Register the new template: Your new provider will submit form 01/�K-HDDT with the updated template details.
5. Test run: Issue test invoices and verify they appear correctly in the tax portal.
6. Go live: Begin issuing official e-invoices through the new platform and archive old records.

Cost Breakdown: What You Actually Pay

Beyond the subscription fee, here are the hidden costs to watch for:

• Digital certificate (ch? k� s?): 500,000 – 1,500,000 VND/year (Viettel-CA, VNPT-CA, FPT-CA).
• Integration development: If you need custom API integration, budget 2,000,000 – 10,000,000 VND one-time.
• Training: Most providers offer free onboarding. Advanced training may cost 500,000 – 1,000,000 VND per session.
• Extra invoice fees: Exceeding the base plan ‘allowance’ typically costs 300 – 800 VND per additional invoice.
