Pay-by-link, also known as payment links, allows businesses to collect payment from customers in a fast and secure way. Businesses need to generate the unique link for the invoice amount and share it with the customers via any means like SMS, email, customer care chat, WhatsApp, telegram, etc. Customers on clicking the link will directly go to the payment page, where they complete the payment using their preferred payment method like, debit card, credit card, mobile wallets, digital wallets, etc. Payment links can also be embedded in QR codes and they could be printed directly on the invoices as well as displayed in-store. Pay-By-Links are relatively a cost-effective solution to collect payments from customers as they don't require costly hardware and systems, making it an ideal choice for small businesses and freelancers.
