What it means
UPI sits on top of the banking system and links bank accounts directly. A user installs an app, links an account and creates a virtual payment address, similar to an email address for money.
To pay, the user enters the address or scans a QR code, confirms with a PIN and the money moves from one account to another almost immediately. Several features explain its rapid adoption.
Different apps and banks work with each other, so a person using one app can pay someone using another. Payments run day and night, including holidays, and a merchant needs only a printed QR code instead of a card terminal.
For businesses, UPI changes cash flow and costs. Settlement is fast, so the money is available the same day instead of after a card network delay.
Fees for merchants have been low or zero under government policy at various times, which is attractive compared with card charges, although policy can change and businesses should check current rules. Finance teams use UPI for collections, supplier payments, payroll top-ups and refunds.
Reconciliation is easier when each payment has a unique reference that can be matched to an invoice, and many accounting systems accept UPI data feeds. The volume of small payments, however, can make bookkeeping heavy without automation.
The model has influenced other countries, and the operator has signed agreements to link UPI with foreign systems for cross-border payments. Other markets have their own instant payment schemes, such as Faster Payments in the UK and Pix in Brazil, so UPI is part of a global move towards real-time payments.
Risks include fraud through fake payment requests, social engineering and mistaken transfers. Users should verify the name shown before confirming a payment and never approve a request they did not initiate.
In practice
Real-world examples.
Example
A street vendor in a city market displays a printed QR code. Customers pay INR 50 or INR 200 for tea and snacks by scanning with their phones, and the vendor sees the money in the bank account straight away.
Example
A small online retailer uses UPI at checkout and finds that payments confirm in seconds. Its finance team matches each payment reference to an order in the accounting system, cutting manual checking time.
Example
A manufacturer pays its transport contractors by UPI on the day invoices are approved. The contractors receive funds immediately, and the manufacturer negotiates a small discount for faster payment.
Formula
Calculation
Monthly saving from moving payments to UPI = Monthly sales through the channel x (Card fee rate - UPI fee rate)
UPI is tied to the Indian rupee, so this example uses INR. A shop sells INR 2,000,000 a month to customers who currently pay by card at an illustrative 1.8% fee, while the same sales through UPI cost an illustrative 0.3%.
Card fees = INR 2,000,000 x 1.8% = INR 36,000
UPI fees = INR 2,000,000 x 0.3% = INR 6,000
Saving = INR 36,000 - INR 6,000 = INR 30,000 a month
Over a year, the saving is INR 30,000 x 12 = INR 360,000. These rates are for illustration only; real fees depend on the provider and the policy in force.Case study
Seen in the real world.
Spice Route Traders is an illustrative, fictional wholesaler that sold mainly through cash and cheque. Collections took on average 12 days, and the owner kept INR 3,000,000 tied up in unpaid invoices at any time.
The firm introduced UPI links on its invoices and offered a 1% early-payment discount for settling within two days. Within three months, about half of its customers paid by UPI, and average collection time fell to 5 days.
The reduction freed up roughly INR 1,700,000 of working capital, which paid down an overdraft at a high rate. The illustrative story shows that faster payments can improve the balance sheet as well as the customer experience.
Watch out
Common mistakes.
- Assuming that UPI payments can always be reversed, when a payment sent to the wrong address generally needs the recipient's cooperation to recover.
- Approving a collect request from an unknown sender, which is a common fraud method.
- Leaving UPI receipts unreconciled, which makes month-end accounts messy.
Questions
People also ask.
Who runs UPI?
The National Payments Corporation of India, an organisation set up to operate retail payment systems in India.
Does UPI work only for small payments?
No, it is used for everyday amounts and larger transfers too, although limits per transaction and per day are set by banks and the operator and can change.
Do businesses pay fees on UPI?
It depends on policy and the provider at the time, so businesses should check the current rules rather than assume a fixed rate.
