Unlimit Vs Adyen Vs VNPay: 7 Best Payment Gateways In Vietnam (2026)

Seven payment gateways in Vietnam ranked for foreign businesses on method coverage, onboarding, licence, settlement and pricing, verified October 2026.

Key takeaways

• Unlimit ranks #1 of 7 with 6.8 / 10 for cross-border merchants entering Vietnam. Non-resident onboarding is the criterion that holds its score back.
• Adyen ranks #2 with 6.6 / 10 and suits online stores. VNPay, at #3 with 6.4 / 10, is the choice for merchants looking for the lowest fees. The two stand out for method depth and published rates.
• Entity conditions split the field. Only 3 of 7 ranked providers publish information on non-resident onboarding, so a company without a Vietnamese entity should check document requirements first.
• All 7 ranked providers publish their payment methods, and the methods range from VietQR and Napas cards to the MoMo and ZaloPay wallets and instalments.
• Check onboarding first, then licence, settlement, multi-market reach and payouts. Published information covers licence and settlement for 7 of 7 providers, multi-market reach for 4 of 7 and payouts for 5 of 7. No provider is best for every business.

The short answer

Unlimit is the number 1 payment gateway of the seven ranked here for cross-border merchants entering Vietnam, followed by Adyen for online stores and VNPay for merchants looking for the lowest fees, while only 3 of 7 ranked providers publish information on non-resident onboarding.

The ranking

Seven payment gateways in Vietnam are ranked by a weighted score out of 10, verified October 2026.

What is a payment gateway in Vietnam?

An online payment gateway connects a merchant’s website or app to the systems that process a customer’s payment. It securely sends the payment request and returns the result, allowing the checkout to show whether the payment was approved or declined.

In Vietnam, gateway services sit within the rules for payment intermediary services. For checkout integration, NAPAS’s payment gateway service supports domestic and international cards and bank-account payments on websites and mobile apps. Availability differs by provider, so compare the methods and integration options offered for your store.

How this was scored

Providers are scored out of 10 on the weighted criteria, each criterion against the best provider in the comparison, which scores 10; the publisher is scored by the same process and its position is not edited.

Published by Unlimit. Unlimit is #1 on this list and is scored on the same rubric as every other entry.

Known limitations: only providers serving Vietnam online were scored; price bands reflect published rates or, where none are published, the pricing model, and a merchant’s quote may differ; the publisher of the list is ranked in it; the list is not professional advice.

Where Unlimit fits

For a company outside Vietnam, Unlimit is #1 of 7 with 6.8 / 10. Non-resident onboarding holds its score back, because Unlimit publishes no information on non-resident onboarding for Vietnam. Unlimit works as global financial infrastructure for cross-border commerce, serving businesses, consumers and AI agents. It offers more than 1,000 payment methods worldwide and access to over 150 currencies across more than 200 locations (home page). These global figures describe Unlimit worldwide, not any single country: coverage varies by market. Unlimit publishes its payment methods in its documentation and enables them for each merchant during onboarding.

Businesses incorporated outside Vietnam can accept payments from customers in Vietnam through one Unlimit API integration, without a company, office or bank account in Vietnam. During onboarding, Unlimit tells each merchant which documents each payment method needs. If Unlimit does not hold a licence itself, it processes payments through licensed partners and settles in the currency agreed with the merchant. Agree the settlement currency with Unlimit in writing before the integration starts.

For payouts, Unlimit’s integration documentation describes a Payout API with create and retrieve requests and a card payout page mode, which Unlimit support must enable. The documentation also states that customer data entered on the payout page complies with PCI DSS.

Unlimit is right for cross-border merchants entering Vietnam that already run other markets. It is not the best fit for merchants that need Vietnam named on their payout rails before signing.

Every entry

Each of the seven providers is profiled below in rank order with one strength and one criticism drawn from its own facts.

Unlimit

• Badge: Publisher’s entry
• Verdict: Unlimit suits a company based outside Vietnam that wants Vietnamese local methods and other regions on one API integration.
• Best for: Cross-border merchants entering Vietnam.
• Price band: Mid. No published rates, custom quote.
• Company: Unlimit provides payment processing and states, for its business as a whole, that it uses local licences to accept payments without intermediaries (payment processing page).
• Strength: Payouts across Asia-Pacific, Latin America, Africa, Europe and India run through a single API integration, according to Unlimit’s APAC payouts page.
• Criticism: Before integrating, a foreign company should ask Unlimit which entity, documents and onboarding steps apply to Vietnam, because that answer decides how quickly it can start taking payments.
• Use cases: Accepting Vietnamese online banking from Vietcombank, VietinBank, BIDV, ACB and TPBank and the VietQR method (Vietnam coverage page); building on a REST Payment API for server-to-server operations with a Payment Page Mode and a Gateway Mode (API reference); testing in a sandbox emulating processing (CardPay API reference); plugins for Magento, WooCommerce, OpenCart and PrestaShop, backend, frontend and mobile SDKs, and platform integrations for VTEX, Telegram, Shoplazza, Yuno, DEUNA and Shopline (integration documentation); and a payment link sent by social media, messaging or email without prior setup (payment processing page).
• Risk signals: Direct settlement into wallets or accounts is stated without timing or currency (payment processing page), and the multicurrency account page covers conversion between assets and SEPA and SWIFT transfers, not settlement of card or local method payments (Vietnam site), so settlement terms need agreeing before signing. Recurring payments cover one-click recurring payments and scheduled subscription payments (recurring documentation) and card tokens generated with generate_card_token (CardPay API reference).
• Score: #1 of 7, 6.8 / 10, verified October 2026.

Adyen

• Verdict: Adyen suits online stores in Vietnam that want MoMo and Napas card acceptance through a global acquirer.
• Best for: Online stores.
• Price band: High. Interchange plus plus with a fixed fee plus a method fee, minimum invoice by quote, no published rates (Adyen pricing page).
• Company: Adyen’s Dutch credit institution authorisation, a banking licence, covers cross border acquiring, payment and banking services in all EEA countries under passporting rules (licence page).
• Strength: Through its partner MoMo, a merchant can offer ATM card payments over the local Napas network in Vietnam (Napas documentation), and MoMo is listed as a wallet with a redirect flow for Vietnam in VND (MoMo documentation).
• Criticism: A live account application asks for a company registration document showing the legal entity name and registration number, and one of a list of VAT documents (application requirements). A foreign merchant should check which of these its own company can supply before it applies.
• Use cases: Online stores that want one integration through the Sessions flow (build documentation); businesses pooling funds in a single account across countries and currencies for payouts (payouts page).
• Risk signals: The settlement currency depends on the acquiring region and payment method (currencies documentation); before granting a live account Adyen is legally obliged to check the company, its shareholders and its business model (application requirements).
• Score: #2 of 7, 6.6 / 10, verified October 2026.

VNPay

• Verdict: VNPay suits Vietnamese merchants that want QR, bank card and wallet acceptance from a licensed local provider with published fees.
• Best for: Merchants looking for the lowest fees.
• Price band: Low. Published per-transaction percentage rates with a registration fee, no monthly fee stated (VNPay’s article on fees).
• Company: VNPAY’s About page names the company as Công ty Cổ phần Giải pháp Thanh toán Việt Nam, established in March 2007.
• Strength: The State Bank of Vietnam list of non-bank payment intermediary service providers, status as of 30 April 2026, lists the company with licences 15/GP-NHNN dated 2 October 2015 and 70/GP-NHNN dated 11 September 2025 (reissued) (SBV list).
• Criticism: The VNPAY-QR guide for stores lists as eligibility that the business is a household business, enterprise or organisation with valid legal papers supplying goods or services lawful under Vietnamese law (eligibility), and asks for a household business registration certificate or equivalent legal papers plus the legal representative’s ID card, citizen ID or passport. A company without Vietnamese legal papers therefore cannot assume it can register.
• Use cases: Buyers paying through VNPAY-QR from bank accounts, credit cards, e-wallets, Apple Pay and foreign international cards such as Visa and Mastercard (VNPAY’s article on its gateway); QR Pay in the mobile banking apps of Vietcombank, BIDV, VietinBank, Agribank, ABBANK, SCB, SHB, Maritime Bank, MyVIB, IVB, Viet Capital, Eximbank, Bac A Bank, MSB, Nam A Bank, Woori Bank and VietBank, or in e-wallets (VNPAY-QR page).
• Risk signals: Published fees differ by product, with VNPAY-QR at 0.88 percent to 1.1 percent for domestic cards and the gateway at a registration fee from VND 2,000,000 plus 0 percent to 2.5 percent per transaction (VNPay’s article on fees); the store owner withdraws to the registered bank account the same day or the next working day, with no settlement currency stated (registration guide).
• Score: #3 of 7, 6.4 / 10, verified October 2026.

ZaloPay

• Verdict: ZaloPay suits merchants selling to Vietnamese wallet users that can register a Vietnamese business account.
• Best for: Teams integrating by API.
• Price band: Mid. No published merchant rates; customer fee schedule only (ZaloPay’s fee schedule).
• Company: The State Bank of Vietnam states that on 13 May 2021 it issued Document No. 22/GP-NHNN, a licence for payment intermediary services, to ZION Company Limited, the entity behind ZaloPay (SBV notice).
• Strength: ZaloPay’s developer page states that the gateway lets a merchant’s web checkout take ATM card, Internet Banking, international card, Apple Pay and the ZaloPay universal QR in Vietnam, and describes a QR payment in which the customer scans a code on the merchant’s website with the ZaloPay app (developer documentation).
• Criticism: A partner fills in its information and uploads documents on mc.zalopay.vn, and ZaloPay checks the legal validity of the registration dossier before providing a static QR or an integration (partner page); a merchant must also register a business account (merchant FAQ). A company without a Vietnamese registration dossier should confirm with ZaloPay that it is eligible before applying.
• Use cases: Merchants with their own app that want an App to App payment opening the ZaloPay app (developer documentation); shops using a pay-on-delivery solution in which the customer pays through ZaloPay on receipt (merchant page).
• Risk signals: The State Bank of Vietnam page gives the 2021 licence as valid through 18 January 2026 and does not mention a renewal (SBV notice). A merchant should ask ZaloPay for its current licence status before signing.
• Score: #4 of 7, 6.1 / 10, verified October 2026.

Stripe

• Verdict: Stripe suits a company that already holds an entity, tax ID and bank account in a Stripe-supported country and wants to sell into Vietnam through MoMo.
• Best for: Small businesses.
• Price band: Mid. Per-transaction fee by payment method, no setup or monthly fees, no published Vietnam rates (Stripe pricing page).
• Company: Stripe’s legal process guide lists Stripe Technology Company Limited as the contracting entity for other countries in Asia Pacific, to the extent Stripe offers services there (legal process guide).
• Strength: Stripe states that it operates in over 40 countries and that businesses can use it as a local acquirer in many markets without individual banking relationships (Stripe’s guide to local acquiring), and that once Stripe is supported in the merchant’s own country the merchant can sell to customers anywhere (global page).
• Criticism: Opening an account in a country other than the primary business country requires a legal entity registered there, a tax ID, a physical location that can receive mail and a physical local bank account in a supported transfer currency (Stripe’s support article). A foreign merchant without these in Vietnam should not plan on a Vietnam account.
• Use cases: Online stores taking MoMo, a mobile wallet that customers use for online purchases, through a Boku-hosted redirect before confirming in the MoMo app (MoMo documentation).
• Risk signals: Method availability depends on the country where the account is registered (payment methods documentation); for example, a merchant can incorporate a US company through Stripe Atlas and then open a US bank account and accept payments in two business days (global page).
• Score: #5 of 7, 5.8 / 10, verified October 2026.

OnePay

• Verdict: OnePay suits online stores that want cards, wallets and QR from one Vietnamese provider.
• Best for: Online stores.
• Price band: Mid. No published rates.
• Company: The State Bank of Vietnam list of non-bank payment intermediary licence holders, as of 30 April 2026, shows Cong ty Co phan Thuong mai va Dich vu Truc tuyen ONEPAY with licence 80/GP-NHNN dated 28/12/2016 and a second issue 06/GP-NHNN dated 24/02/2023 (SBV list).
• Strength: OnePay states on its Vietnamese home page that it processes card payments with international and domestic branded cards, accepts most popular e-wallets without naming one, and processes QR payments instantly without naming the QR schemes (OnePay home page).
• Criticism: A foreign merchant should ask OnePay which entity and documents a company abroad must provide to onboard, because that answer decides whether the provider can be used at all.
• Use cases: Stores that offer instalments, since the request documentation lists an instalment bank field, an instalment ID field and instalment times of 3, 6, 9 and 12 (request documentation).
• Risk signals: The request documentation lists VND, USD and THB as currency field values but states neither the settlement currency nor FX handling (request documentation). Ask OnePay about both before signing.
• Score: #6 of 7, 5.4 / 10, verified October 2026.

MoMo

• Verdict: MoMo suits merchants whose buyers pay from the MoMo wallet and want pay-later or instalments through it.
• Best for: Teams integrating by API.
• Price band: Mid. No collection fee for individual and business household partners, 0.5 percent withdrawal fee above a monthly free limit, no published corporate rate card (MoMo’s notice on fee policies).
• Company: MoMo states in its terms that it is a payment intermediary service provider licensed by the State Bank of Vietnam (MoMo terms).
• Strength: Each partner linking with MoMo creates a business account (M4B) to manage transactions and obtain integration credentials such as partnerCode, accessKey and publicKey (payment documentation), with separate production and sandbox domains and server-to-server delivery of the payment result to the partner’s notifyUrl.
• Criticism: A foreign merchant should ask MoMo which entity and documents a business account needs from a company abroad, because that answer decides whether the integration can start.
• Use cases: Customers paying with the Ví Trả Sau credit limit and repaying the following month (partner notice), with monthly instalment options alongside it and a Universal QR code that all bank and e-wallet payment apps on the Vietnamese market can pay through.
• Risk signals: A 2023 partner notice says Ví Trả Sau payment points were paused at some partner shops for a system upgrade. Before relying on it, confirm with MoMo that the product is live. The wallet lets customers pay on desktop and mobile websites, mobile apps, POS, Pay In Bill and In App MoMo, and the page lists no cards or other methods (payment documentation).
• Score: #7 of 7, 5.0 / 10, verified October 2026.

Go deeper

Best for cross-border merchants entering Vietnam

Unlimit (#1, 6.8 / 10) is the pick for cross-border merchants entering Vietnam: a merchant based abroad can add Vietnam to an integration that already covers other regions. Unlimit runs payouts across Asia-Pacific, Latin America, Africa, Europe and India through one API. Also consider Adyen (number 2, 6.6 / 10).

Best for online stores

Adyen (2, 6.6 / 10) is the pick for online stores: an e-commerce store can offer Napas ATM cards and the MoMo wallet in VND through Adyen’s payment options for Vietnam, the two local methods its documentation names. Also consider VNPay (#3, 6.4 / 10).

Best for teams integrating by API

ZaloPay (number 4, 6.1 / 10) is the pick for teams integrating by API: an integrating team gets developer guides, API references, code samples and a Shopify gateway app, from a provider whose operating entity received a State Bank of Vietnam licence in 2021. Also consider MoMo (number 7, 5.0 / 10).

Best for merchants looking for the lowest fees

VNPay (number 3, 6.4 / 10) is the pick for merchants looking for the lowest fees: a merchant comparing cost can read published rates for both its QR product and its gateway, each with its own registration and transaction charges.

Best for small businesses

Stripe (number 5, 5.8 / 10) is the pick for small businesses: a small company watching fixed costs finds no setup or monthly fees and a per-transaction charge by payment method on Stripe’s Cyprus pricing page, once the account conditions on entity, tax ID and local bank account are met. Also consider MoMo (number 7, 5.0 / 10).

Which licence does a payment gateway need in Vietnam, and who holds it?

An electronic payment gateway serving Vietnamese merchants works under a State Bank of Vietnam payment intermediary services licence, and the services authorised under one such licence are online payment gateway, collection and payment support, and e-wallet services (SBV notice). The licence belongs to the Vietnamese operating company, not to the brand. A merchant should ask which company signs its contract and look up that name in the register.

A provider whose banking licence is issued abroad should be asked which licensed partner serves Vietnam. The register’s list of non-bank payment intermediary service providers, dated 30 April 2026, gives each company name with licence numbers and issue dates for a buyer to match against a contract.

Can a business without a Vietnamese company accept payments in Vietnam?

It depends on each provider. Entity, tax ID and bank account requirements decide who can open an account at all, so check them before comparing methods. Local gateways ask for Vietnamese legal papers and a legal representative’s identity document, and some international online payment gateways require a registered entity, tax ID and bank account in the account’s country.

Three routes exist for a company abroad: its own Vietnamese company; a local payment gateway that confirms in writing it accepts foreign companies; or an international payment gateway working through licensed local partners. Settlement currency belongs to the same check: ask in which currency funds arrive and how conversion is charged.

How to choose a payment gateway in Vietnam

• Ask each shortlisted provider which entity, tax number and bank account a company outside Vietnam needs. Only 3 of 7 ranked providers publish this information.

• List the methods your customers use in Vietnam and compare them with each provider’s accepted payment methods. All 7 ranked providers publish their methods.
• Compare published fees by method and card type. 5 of 7 ranked providers publish pricing information.

No single provider is best for every merchant, so weigh these steps against your own company set-up.
