As a fast-growing business, you need to build a sustainable business model, crack the ideal product-market fit, and craft effective go-to-market strategies. With a booming digital economy, your customers aren\u2019t limited to a single geography and the entire world is your playground. That\u2019s where payment gateways come in, to enable your business to seamlessly collect payments from within as well as outside India. What is a Payment Gateway? A payment gateway is a connection between a merchant\u2019s website or mobile app and the bank. When a customer makes payments through a payment gateway, the merchant\u2019s website or mobile app sends the details of their debit card\/credit card or bank account to the gateway. Once the payment gateway verifies these details from the bank, the amount gets transferred from the customer\u2019s bank account to the merchant\u2019s bank account. The access to a market is defined by the ability to collect online payments from customers in a particular geography. This is more pronounced in the context of SaaS applications and other web-based offerings. For SaaS companies, there are several payment gateways you can use to charge customers on a recurring basis. If you are a company registered in India, the Reserve Bank of India (RBI) eased the mandates on two-factor-verifications for low-value recurring payments using payment methods like cards, net banking, and wallets. This has paved the way for many payment gateways in India to support recurring billing. If you are a business that is incorporated in the US, you will need a bank account in the USA. You could get a merchant account separately from any merchant bank or go with the merchant account provider suggested by your chosen payment gateway. Choose a payment gateway that\u2019s most convenient for your customers and the geography they are in. This will pave the way for the easy adoption of your products\/services.
