Management software + devices + payments + e-invoice — one TCONNECT platform
Cash register, card terminal, Soundbox, website, mobile app, self-service kiosk — together with every payment method and automatic e-invoicing, in a single integration. That is TCONNECT: unified payment infrastructure for management software and omnichannel businesses.
Instead of stitching together management software with a separate payment gateway, a separate device type and a separate e-invoice provider, TCONNECT brings everything into one platform, one integration: accept money across every device and channel (card terminal, Soundbox, kiosk, website, mobile app, cash register), through every method (VietQR, domestic/international cards, e-wallets, Pay-by-Bank, QR Global), issue e-invoices automatically the moment a payment succeeds, and have funds settle straight to your bank account with centralized reconciliation.
What does “all-in-one” mean?
A modern point of sale is more than just software. It has three layers that must fit together: (1) management software (sales, inventory, customers, branches); (2) payment devices & channels (POS, Soundbox, kiosk, web, app); and (3) payment + invoicing infrastructure (payment methods, reconciliation, invoice issuance).
In the traditional approach, these three layers come from many different vendors — software in one place, a bank's card terminal, an online payment gateway somewhere else, and e-invoicing from yet another vendor. TCONNECT unifies layers (2) and (3) and plugs neatly into layer (1), so businesses and software makers only deal with a single partner.
Accept payments at every touchpoint
Customers pay at the counter, at the table, on the web, in the app or at a self-service kiosk — TCONNECT covers them all with the same infrastructure and the same reconciliation dashboard:
| Device / channel | Role | Best for |
|---|---|---|
| Cash register / soft POS | Sell at the counter, print receipts, connect to management software | Retail, F&B, store chains |
| Card terminal (card-present POS) | Swipe/tap domestic & international cards at the point of sale | Stores, restaurants, hotels |
| Soundbox | Voice speaker confirming funds received instantly | Busy counters, multiple cashiers |
| Website / online gateway | Collect money on your web store, booking or fee pages | E-commerce, services, SaaS |
| Mobile app / SDK | Embed payments into your own application | Sales apps, booking apps, in-app wallets |
| Self-service kiosk | Customers self-select, self-pay and self-collect invoices | Self-service ordering, cinemas, entertainment venues |
One integration — every way to pay
Turn methods on or off as needed, without re-integrating each one:
- ✓Dynamic VietQR & VA: QR codes generated per order, or Virtual Accounts for automatic reconciliation.
- ✓Domestic (Napas) cards and international cards (Visa, Mastercard, JCB) — both online and card-present at the counter.
- ✓E-wallets popular in Vietnam.
- ✓Pay-by-Bank — bank transfer right inside the payment flow.
- ✓QR Global — accept payments from foreign tourists through their own apps.

Issue invoices the instant payment succeeds
Payments and invoicing share the same infrastructure, so the e-invoice is issued automatically at the moment the transaction succeeds — no manual steps, no data drift between two systems.
Buyer details can be auto-filled via tax-code lookup, and the system connects to multiple invoice providers through the Invoice Hub. Read more: Invoice Hub and tax-code lookup.
Why is a patchwork of vendors so costly?
- !Many vendors, many contracts: software, card terminal, online gateway, invoicing — each in a different place, each with its own terms and its own support contact.
- !Fragmented reconciliation: money arrives from many channels and must be pieced together by hand from different reports — error-prone and time-consuming at day-end/month-end.
- !Repeated integration: every new device/channel/method means writing and maintaining yet another separate integration.
- !Disjointed customer experience: each channel has a different payment flow, making it hard to unify branding and speed.
What does TCONNECT deliver?
- 1One integration, every channel: connect once, then switch on more devices/channels/methods without rewriting anything.
- 2Centralized omnichannel reconciliation: every transaction — counter, web, app, kiosk — lands on one dashboard and matches automatically.
- 3Funds settle straight to your bank: transparent cash flow, to the right account holder, with no intermediary holding the money.
- 4Automatic e-invoicing: issued the moment you collect payment, valid, reducing errors and data entry.
- 5International-grade security: PCI DSS and tokenization — the merchant/software never has to store card data.
- 6Fast to deploy, no lock-in: standardized APIs, friendly to developers and AI coding agents, no vendor lock-in.
Safe at every touchpoint
Accepting cards at the counter, on the web or in the app all demand a high security bar. TCONNECT processes card data on PCI DSS-compliant infrastructure and uses tokenization to replace real card numbers with tokens — so your management software and the merchant never store card data (CHD), sharply reducing compliance scope and leak risk.
The result: you accept card payments securely without building and certifying an expensive security infrastructure yourself.
TCONNECT versus the alternatives
Compared with using a standalone online gateway, a single bank POS, or stitching together multiple vendors yourself:
| Criterion | Pure online gateway | Single bank POS | DIY multi-vendor | TCONNECT all-in-one |
|---|---|---|---|---|
| Devices & channels | Web/app only | Card-present at counter only | Varies by vendor, you connect it all | POS, Soundbox, kiosk, web, app, cash register |
| Methods | Online cards/wallets | Cards at counter | Each vendor covers a part | VietQR, cards, e-wallets, Pay-by-Bank, QR Global |
| E-invoice | Usually separate | None | Add another vendor | Automatic, built in |
| Reconciliation | Per online channel | Per device | Fragmented across sources | Centralized, omnichannel |
| Integration count | A part of it | Standalone | Many times, hard to maintain | A single time |
| Card security | Depends on gateway | The bank's | Inconsistent | PCI DSS + tokenize |
| Settlement | Through the gateway | To the bank | Varies by vendor | Straight to your account, transparent |
Who should use an all-in-one platform?
- ✓Retail & store chains: many branches, many counters, needing centralized reconciliation and fast settlement.
- ✓F&B & restaurants: collect at table/counter by QR and card, Soundbox confirming payment, automatic invoicing.
- ✓Hotels, spas, services: deposits, payment at check-out/service end, automatic invoices.
- ✓Education, healthcare: collect tuition and hospital fees across channels, self-service kiosks reducing queues.
- ✓ERP/POS/SaaS developers: embed payments + invoicing into your product without building the infrastructure.
Embed payments + invoicing into your software
If you build management software (ERP, POS, SaaS, PMS, HIS), TCONNECT gives you a standardized set of APIs to embed omnichannel payments and e-invoicing into your product — instead of integrating and maintaining each gateway, each device and each invoice vendor.
Full documentation, sandbox and webhooks at docs.tconnect.vn; the APIs are designed to be friendly to both developers and AI coding agents to shorten integration time.
From sign-up to going live
- 1Consult & choose configuration: pick the devices/channels (POS, Soundbox, kiosk, web, app) and methods that fit your model.
- 2Connect once: integrate the API or use plug-and-play devices; enable automatic e-invoicing.
- 3Test on sandbox: validate the collect-payment and invoice-issuance flows before going live.
- 4Operate & reconcile: collect across channels, funds settle straight to your bank, centralized reconciliation every day.
