Simulated walkthrough · Sample data

Problem · Benefit

Collect payments without combing through bank statements.

The three tasks that cost accounting and sales the most time.

  • Problem

    After a customer transfers money, someone has to open the banking app and check every transaction.

    With NEXT OS

    Bank QR payments are confirmed automatically and matched to the invoice.
  • Problem

    Quotes sit in loose files sent over Zalo, and when a customer asks again nobody can find them.

    With NEXT OS

    Quotes, contracts and invoices are created and kept in the customer profile.
  • Problem

    You forget to remind customers when payment is due, and unpaid balances pile up.

    With NEXT OS

    Recurring invoices and payment reminders go out automatically.

Features

From quote to money in the bank.

01

Quotes and contracts

Build quotes from your product and service catalog; customers view and accept them online. Contracts go out for e-signature and are kept in the customer profile.

  • Product, service and price catalog
  • Customers accept quotes via a link
  • E-signed contracts kept in the profile

02

Invoices and payment links

Turn an accepted quote into an invoice or create one from scratch, then send it by email or message. Customers click the link to pay by bank QR or card.

  • One-off or recurring invoices
  • Payment links sent by message or email
  • Automatic due-date reminders

03

Auto-confirmed bank QR payments

Customers scan a QR code to transfer, and the system matches the payment and marks it paid. A completed payment can trigger a workflow that sends a thank-you message or grants course access.

  • Vietnamese bank QR
  • Card gateways: Stripe, PayPal (from Professional)
  • Workflows run after payment

FAQ: Payments & Invoices

How are bank QR payments confirmed automatically?

Customers scan the QR code on the invoice or payment page to transfer. When the money arrives, NEXT OS matches it and marks the invoice paid. The NEXT team helps you connect the account during onboarding.

Does NEXT OS issue VAT e-invoices?

Invoices in NEXT OS are for billing customers and collecting payment. VAT e-invoices are still issued through your own e-invoice provider.

Can I accept international cards?

Yes, through Stripe or PayPal from the Professional plan. Transaction fees are charged by the payment gateway.

Can I send recurring monthly invoices?

Yes. Set up a recurring invoice schedule and the system sends it and reminds customers when payment is due.

Can a payment trigger the next step automatically?

Yes. A successful payment can trigger a workflow: send a thank-you message, move the deal to the next stage or grant course access.
