Online payments for a small business: UPI, cards and gateways explained

To take payments on your website you usually need a payment gateway, a service that collects money securely and sends it to your bank account.

How it works

  1. The customer chooses to pay at your checkout.
  2. The gateway shows its secure payment page or window: UPI, cards, net banking or wallets.
  3. The gateway confirms the payment to your site.
  4. The money reaches your bank account after a settlement period.

UPI

UPI is the most popular method in India for small payments, and many gateways include it. You can also share a payment link or QR code directly for simple orders.

What you usually need to apply

  • Business details and a bank account
  • PAN, and GST details if you are registered
  • A live website with clear contact, policy and pricing pages

Approval can take some days, so start early. Each gateway has its own rules.

What to compare

  • Fee per transaction and for each method
  • Settlement time
  • Refund process
  • Support quality

Test before going live

Use the gateway's test mode and then place one small real order yourself, and refund it, so you know the whole flow works.

Keep records

Match payments with orders and issue invoices, as your accountant will need them.

We connect payment gateways in our e-commerce websites and SaaS payment integration.
