UPI: Anatomy of a Payment Transaction

What actually happens when you make a UPI payment?

A UPI payment travels from the payer's app to a Payment Service Provider bank, then through the NPCI switch to the payee's bank. The money moves account to account, not through a card network. That is the key difference from the card payments most UK businesses accept.

The scale is striking. UPI processed a record 24.51 billion transactions worth about ₹29.82 lakh crore in August 2026, up from 23.66 billion in July, according to NPCI data reported by Business Standard and Entrackr.

Why does a payment system in India matter to a UK small business?

It shows what happens when bank-to-bank payments become the default: card fees stop being a fact of life. UPI is live in about nine countries, and NPCI International has said it wants over 20 by 2027. Talks with the UK have been reported but are not confirmed as live.

So do not wait for UPI to arrive. The UK already has its own account-to-account rails, and they are the real story for your business.

Is the UK building something similar?

Yes, through open banking. Open Banking Limited cites 17.5 million connections and 145 authorised third-party providers, while a June 2026 secondary report puts activity at over 40 million payments a month. It is smaller and less universal than UPI, but it is live and usable now.

EY analysis for Open Banking Limited estimates a £2.3 billion annual GDP uplift for UK SMEs within five years. Treat that as a forecast, not a promise.

What is the UK equivalent of UPI-style repeat payments?

Variable Recurring Payments (VRPs) are the closest match. They let a customer authorise a business to pull payments from their bank account within agreed limits, useful for subscriptions, memberships and repeat bookings. One secondary source reports VRPs grew 6.7% in a month to 7.73 million transactions.

That is still small next to card volumes. It is growing, though, and it is worth understanding before your competitors do.

Does this mean UK small businesses should drop card payments?

No. Customers still expect cards, Apple Pay and Google Pay, and a pay-by-bank button alone will lose sales. The sensible move is to offer pay by bank as an additional option, then see whether customers choose it.

Our view at Braynex Services: the winners will not be the businesses that chase each new payment method. They will be the ones that own their checkout, so they can add or swap methods without rebuilding anything.

Why is one dominant app a warning for small businesses?

In August 2026, PhonePe held about 45.89% of UPI volume, Google Pay 32.33% and Paytm 8.05%. A few apps carry most of the traffic, and whoever controls the front door sets the terms for everyone else.

We see the same pattern with rented platforms. A nail salon we worked with was paying Fresha about £1,800 a month in commission. Moving to its own booking system at £35 a month saved roughly £21,000 a year. Payments follow the same logic: the less you depend on one intermediary, the more of your margin you keep.

What should I do this month?

1. Check your real card costs. Add up processing fees, platform commissions and monthly terminal charges from the last three months.
2. Ask your provider about pay by bank. Many UK processors now offer open banking payments. Ask for the per-transaction fee compared with cards.
3. Test it on one product. Try it on deposits, invoices or high-value orders, where percentage card fees hurt most.
4. Look at repeat customers. If you take regular bookings or memberships, ask whether VRPs could replace chasing payments.
5. Own the checkout. Make sure payments run through your own website and booking system, not someone else's marketplace.

What is Braynex Services' view?

UPI is a useful lesson, not a UK to-do item. Cheap, direct bank payments only help if you control the point of sale. Braynex Services builds websites, booking systems and payment flows that businesses own outright, so adding pay by bank later is a settings change, not a rebuild.
