Business licence due diligence tests something a share purchase agreement cannot fix after the fact: whether the target is legally entitled to carry on the business the buyer is paying for. A clean set of financial statements says nothing about whether the underlying revenue was earned under a valid, current and correctly scoped licence.
This guide sets out a practical ten-point review for buyers acquiring a Vietnamese company across regulated sectors: how to build a complete licence inventory, verify scope and conditions against actual operations, and convert gaps into conditions precedent, warranties or price adjustment before signing.

Business licences can determine whether a Vietnamese target is legally able to generate the revenue shown in its accounts. A company may hold an enterprise registration certificate and still lack a sector-specific approval, operating permit, sub-licence or mandatory professional certificate. For a buyer, this creates a direct risk: an apparently profitable activity may be suspended, fined or forced to restructure after closing.
This guide explains how to conduct due diligence of business licences and regulatory conditions in a Vietnam acquisition. It focuses on practical verification, change-of-control exposure and the protections a buyer should build into the transaction documents.
Why business licence due diligence matters in Vietnam
Vietnam regulates many activities through overlapping laws, decrees, technical standards and local administrative practice. The target’s registered business lines are only the starting point. Depending on the sector, lawful operation may also require approvals relating to investment, construction, fire prevention, environment, food safety, education, healthcare, logistics, e-commerce, advertising, tourism or professional services.
A missing or defective licence can affect valuation, financing and the closing timetable. It can also expose the buyer to administrative sanctions, remediation costs and business interruption. Licence review should therefore be coordinated with the broader Vietnam M&A due diligence checklist.
Buyers who skip business licence due diligence typically discover the gap only after closing, at the point when a regulator, a landlord, or a customer asks for proof of a licence the target does not actually hold. By then the buyer owns the problem outright, with none of the leverage a pre-signing negotiation would have given it. A properly scoped business licence due diligence exercise turns that discovery into a negotiating point instead of a post-closing liability.
In short, business licence due diligence protects deal value; skipping it merely defers the cost.
1. Build a complete regulatory inventory
Begin by mapping every activity, product, facility and revenue stream of the target. Compare the actual business with its enterprise registration, investment registration and internal descriptions. Management interviews should cover activities conducted through branches, warehouses, websites, agents and outsourced operators.
The inventory should record each required approval, the issuing authority, licence number, holder, covered location, permitted scope, validity period, renewal date and continuing conditions. Do not rely on a generic list copied from another transaction; licensing requirements depend on the target’s precise operating model.
Business licence due diligence should start with a single master inventory rather than a pile of scanned certificates. For each site, activity and revenue line, record the licence type, issuing authority, licence number, date of issue, expiry date, renewal deadline, conditions attached, and the person or department responsible for compliance. Cross-reference the inventory against the target management accounts by revenue line: any revenue stream that cannot be matched to a corresponding licence entry is the clearest signal that the register is incomplete rather than that the licence does not exist.
A master inventory is the single artefact that makes business licence due diligence auditable: it lets the buyer legal team, the seller and, later, the buyer own compliance function all work from the same list rather than reconstructing it from memory after closing.
2. Verify the original documents
Request complete, legible copies of each licence and inspect originals for material approvals. Confirm that the legal name, enterprise code, address and authorised scope match current corporate records. Check amendments, annexes, renewal decisions and correspondence with regulators.
Where a public database exists, compare the licence against the regulator’s online record. If the approval is central to the investment thesis, consider written confirmation or a pre-closing meeting with the competent authority, subject to confidentiality and transaction strategy.
Do not rely on scanned copies provided in the data room. Business licence due diligence requires verification with the issuing authority or through the relevant national business and licensing information portals, because copies can be outdated, amended without the buyer knowledge, or in rare cases altered. Confirm the current legal representative named on each licence matches the company records, since a licence issued to a since-departed legal representative can create a defect that is easy to miss on paper but expensive to cure after closing.
Verification is not optional: business licence due diligence findings based only on data-room copies are worth little if the underlying document cannot be confirmed with the issuing authority.
3. Test the licensed scope against actual operations
A valid document may still be inadequate if the target operates beyond its permitted scope. Review customer contracts, invoices, product catalogues, websites, facility layouts and management accounts. Trace material revenue lines back to the relevant licensed activity.
Common discrepancies include operating at an unregistered location, selling products outside an approved category, exceeding licensed capacity, using an approval held by an affiliate, or conducting conditional activities before all prerequisites were satisfied.
A licence that exists is not necessarily a licence that covers what the company actually does. Compare the approved business lines, geographic scope, product categories and permitted activities stated on each licence against the target real trading activity, marketing materials and customer contracts. Business licence due diligence frequently finds that a company has expanded into adjacent products or channels, such as online sales or a new province, without updating the corresponding licence, which exposes the business to administrative sanctions and, in some sectors, contract unenforceability.
Where the mismatch between licensed scope and actual operations is significant, business licence due diligence should also test whether the revenue attributable to the unlicensed activity is separable, because a buyer may be able to price around a discrete gap far more easily than around one embedded across the whole revenue base.
4. Review continuing regulatory conditions
Many Vietnamese licences remain effective only while the holder maintains specific conditions. These may relate to minimum capital, qualified personnel, facilities, equipment, insurance, security, technical standards or reporting. A licence that appears current can become vulnerable if those conditions are no longer maintained.
Review employment records and certificates for key licensed personnel. Confirm ownership or valid leases for required premises and equipment. Examine periodic reports, inspection minutes, testing certificates and proof of statutory insurance. Any condition dependent on a founder or seller should receive special attention before closing.
Many licences remain valid only while the holder continues to satisfy conditions imposed at issuance, such as minimum charter capital, a qualified professional on staff, specified facility standards, or ongoing reporting to the licensing authority. Confirm the target has continuously met these conditions, not merely that it met them on the day the licence was issued, because a lapsed condition can expose the licence to suspension or revocation even where the certificate itself has not expired.
Ongoing conditions are the part of business licence due diligence most often missed by teams that focus only on the expiry date printed on the certificate itself.
5. Check expiry, renewal and reporting deadlines
Create a calendar of licence expiry dates, renewal lead times and recurring filings. Some renewals require inspections, updated technical documents or proof that historic reporting obligations were met. A renewal due shortly after completion may become the buyer’s immediate operational problem.
The seller should complete overdue filings and start any long-lead renewal before closing. The acquisition agreement can require evidence of submission, regulator acceptance and delivery of the renewed licence as a condition precedent where the permit is critical.

Build a forward-looking calendar of every expiry and periodic reporting deadline across the licence inventory, extending at least two years past the expected closing date. Business licence due diligence should flag any licence expiring within twelve months of signing as a priority item, because renewal timelines and evidentiary requirements vary by authority and can extend well beyond the deal timetable if the application is not lodged early.
A renewal calendar produced during business licence due diligence should be handed to the post-closing compliance owner, not archived with the transaction file once the deal signs.
6. Investigate inspections and enforcement history
Request inspection records, warning letters, penalty decisions, remediation plans and communications with regulators for at least the material limitation period. Interview operational managers rather than relying only on the legal team. Local facilities often retain important correspondence outside the central data room.
Repeated minor breaches may reveal a weak compliance culture. Unresolved findings can lead to enhanced supervision, suspension or difficulty renewing an approval. They may also point to hidden liabilities that should be reviewed alongside hidden debt and off-balance-sheet liabilities.
Request the target complete inspection and enforcement history for the past three to five years, including any warnings, administrative fines, suspension orders or corrective action requirements, together with evidence that corrective actions were actually completed and accepted by the authority. An unresolved enforcement finding is a stronger indicator of licence risk than the paper status of the licence itself, because it shows the authority already has an open file on the target.
Business licence due diligence should also check whether any enforcement action was reported to, or discovered by, a material customer or lender, since reputational consequences can persist even after the underlying finding has been formally resolved with the authority.
7. Analyse foreign ownership restrictions
A transaction can change the regulatory status of the target even if its activities remain the same. Foreign ownership may trigger market-access conditions, ownership caps, joint-venture requirements or additional investment procedures. The analysis must consider the buyer’s ultimate ownership, not merely the immediate acquisition vehicle.
Confirm whether the post-closing structure remains compatible with each licence. Some authorities may require an amendment, reissuance or new application. Build these steps into the regulatory roadmap and closing schedule.
Where the buyer is a foreign investor, confirm whether the target sector falls within Vietnam conditional market access categories and whether any foreign ownership cap, joint venture requirement or investor qualification applies to the licensed activity, separately from the general foreign investment approval for the transaction. Business licence due diligence should map this analysis against the proposed post-closing ownership structure, since a structure that clears general foreign investment rules can still breach a sector-specific ownership limit attached to a particular licence.
Foreign ownership analysis belongs squarely inside business licence due diligence rather than being treated as a separate workstream, because the sector-specific cap frequently attaches to the licence itself rather than to the company generally.
8. Identify change-of-control consequences
Licences differ from commercial contracts, but both may react to an ownership change. Review whether the approval is personal to the holder, transferable, location-specific or dependent on named personnel. Determine whether notification, consent or amendment is required before or after completion.
This review should be coordinated with the analysis of change-of-control clauses in Vietnamese commercial contracts. A buyer needs both the regulatory approvals and the contractual rights necessary to operate the business after closing.
For each licence in the inventory, determine whether a change of control triggers a notification, a re-approval, or no action at all. Some licensing regimes are indifferent to a change of shareholder because the licence attaches to the legal entity; others are conditioned on the identity, nationality or qualifications of the shareholders or the legal representative and require prior consent before the transaction may close. Treat any licence requiring prior regulatory consent to the change of control as a condition precedent rather than a post-closing formality.
Getting the change-of-control analysis wrong is one of the most expensive mistakes business licence due diligence can miss, since a licence lapse discovered after signing is far harder to cure under time pressure.
9. Assess branches, sites and digital channels
Do not limit the review to the head office. Each factory, shop, clinic, training centre, warehouse or branch may need separate approvals. Environmental, construction and fire-safety requirements are commonly tied to a specific property.
Digital activities also require attention. Websites, mobile applications and online marketplaces may trigger e-commerce notification or registration obligations, cybersecurity requirements, consumer rules and sector-specific advertising restrictions.
Licence requirements frequently apply per site rather than to the company as a whole. Confirm that each branch, warehouse, retail location and, increasingly, each digital sales channel or platform listing has the licence or notification the relevant regulator requires. Business licence due diligence often uncovers that a licence obtained for the head office was never replicated for a newer branch or an e-commerce channel added after the original licence was issued.
Site-by-site verification is time-consuming, but it is where business licence due diligence most often finds the gap that a head-office-only review would miss.
10. Translate findings into transaction protection
Classify findings as closing blockers, price issues, indemnity matters or post-closing remediation. Critical missing licences should normally be cured before completion. Where cure is possible but timing is uncertain, the buyer can use conditions precedent, holdbacks, escrow or deferred consideration.
Representations should cover the completeness and validity of licences, compliance with continuing conditions, absence of undisclosed enforcement and accuracy of regulatory filings. Specific indemnities are appropriate for identified historic breaches. Covenants should restrict changes to licensed operations between signing and closing.
Map each finding to the appropriate remedy. An expired or missing licence essential to current revenue becomes a condition precedent with a defined output and long-stop date. A licence with an open enforcement matter or unresolved condition becomes a specific indemnity, sized to the realistic cost of remediation or penalty. A licence requiring change-of-control consent becomes a condition precedent naming the specific consent required. Where the scope mismatch is systemic rather than isolated, it may justify revisiting the valuation itself rather than attempting to indemnify around a structural compliance gap.
This mapping exercise is the point at which business licence due diligence stops being a diagnostic report and starts being enforceable contract language.
A practical red-flag checklist
- Material revenue comes from an activity not clearly covered by an approval.
- A licence is held by a shareholder, employee or affiliate rather than the target.
- Required qualified personnel plan to leave at closing.
- Facilities operate at addresses not listed in the relevant approvals.
- Renewals or periodic reports are overdue.
- Inspection findings remain unresolved.
- Foreign ownership will breach a sector condition.
- The licence requires consent or reissuance following the acquisition.
Treat the following as escalation points during business licence due diligence: a licence certificate that cannot be verified with the issuing authority, revenue generated from an activity with no corresponding licence, a licence conditioned on a legal representative who has since left the company, an unresolved inspection finding older than twelve months, and a licence expiring within six months of the expected closing date with no renewal application yet filed.
Each of these red flags should prompt deeper business licence due diligence work before signing, not a note for the post-closing integration plan.
A checklist is a starting point for business licence due diligence, not a substitute for the underlying document verification described above.
Conclusion
Effective licence due diligence connects documents to real operations. Buyers should verify the approval, test its scope, confirm continuing conditions and model the effect of the proposed ownership change. The final output should be a regulatory matrix with owners, deadlines and clear transaction consequences—not merely a folder of permits.
For a Vietnam acquisition, early regulatory analysis protects the deal timetable and prevents the buyer from acquiring a business that cannot lawfully operate as expected after closing.
Business licence due diligence is not a formality to be delegated entirely to junior staff or satisfied by a checklist of certificate photographs. It is a substantive test of whether the business the buyer is paying for is the business it is legally entitled to operate. Buyers who commit the time to verify original documents, test licensed scope against actual operations, and translate findings into conditions precedent and indemnities close with real protection rather than a false sense of comfort.
Frequently asked questions about business licence due diligence
What is business licence due diligence?
It is the process of identifying every licence, permit, sub-licence, certificate and approval a target needs to lawfully operate, verifying that each one is genuine, current and unexpired, and testing whether the scope of each licence actually matches what the business does in practice, including its branches, sites and digital sales channels.
Why can a company have an enterprise registration certificate but still operate unlawfully?
Enterprise registration confirms the company exists and states its registered business lines, but many sectors in Vietnam, such as real estate brokerage, education, logistics, retail distribution for foreign-invested enterprises, finance and healthcare, require a separate sub-licence, operating permit or conditional business line certificate before the company may lawfully generate revenue from that activity. A target can be duly incorporated and still be trading outside its licensed scope.
What happens to licences on a change of control?
Some Vietnamese licences and permits are granted to the licensed entity and continue automatically through a share acquisition, since the legal entity does not change. Others are conditioned on ownership, management or specific approved individuals, and a change of control can trigger a notification obligation, a re-approval requirement, or in some conditional sectors a fresh review of the foreign investor. Business licence due diligence should identify which licences fall into each category before the transaction structure is fixed.
How should a licence gap change the transaction?
Treat an expired, unscoped or missing licence that is essential to current revenue as a condition precedent, with a defined output such as the issued licence or filed renewal, because an indemnity does not restore the right to operate. A licence that is technically in place but carries unresolved compliance findings, such as an unpaid fine or an open inspection, is better handled with a specific indemnity and, where the exposure is quantifiable, a price adjustment.
Who should carry out business licence due diligence?
Local regulatory counsel should lead the review, because licence requirements are sector-specific and often set out in decrees, circulars and local administrative guidance rather than the Law on Enterprises alone. Counsel should verify original documents with the issuing authority rather than relying on copies in the data room, and should coordinate closely with tax, land and labour due diligence, since a missing licence often has knock-on consequences in those areas too.
