You raise an invoice and now need to get paid without chasing a bank transfer reference by phone. Two common ways: send a payment link the customer clicks and pays through, or send a UPI collect request that pops up in their UPI app for them to approve. They look similar from the customer's side, but they behave differently enough to matter for a small firm.
How a payment link works
- Works over WhatsApp, SMS or email, and on any payment method the customer's browser supports — UPI, card, net banking.
- The customer has to open it and complete the payment; nothing happens automatically.
- Good for one-off invoices sent to a wide range of customers, including ones without UPI set up.
How UPI collect works
- A request goes straight into the customer's UPI app for them to approve — no separate page to load.
- Needs the customer's UPI ID upfront, so it suits repeat customers more than first-time ones.
- Collect requests have been tightened over time against misuse, so approval rates and limits can vary by app.
What it costs you
A payment link is the more flexible default — it reaches anyone, on any device, through whatever channel you already message them on. UPI collect is faster for repeat customers you already have a UPI ID for, but is worth less for a new or occasional customer. Whichever you use, tie the payment status back to the invoice automatically — a paid invoice that is not marked paid in your books is exactly the reconciliation problem you were trying to avoid. Keep a fallback option too: a customer whose UPI app is acting up on a given day should still be able to pay by card or net banking through the same link, rather than being stuck.
Questions to ask any vendor
- Does a payment automatically mark the matching invoice as paid, or do you check manually?
- Can you send both a link and a collect request, and pick per customer?
- Where does the settlement land — directly in your account, or through an intermediate wallet?
