A plain-English explanation of payment gateways, how they process UPI and card payments in India, what they cost, and how they differ from payment aggregators.
A payment gateway is the software that lets a business accept digital payments - it securely carries a customer's payment from their bank or UPI app to your account. If you sell anything online in India, a payment gateway is the piece that actually collects the money.
All of this happens in a few seconds at checkout. The gateway's job is to make it secure, fast and reliable.
These terms get mixed up. A payment gateway is the technology layer that captures and routes the payment. A payment aggregator (which is what most Indian SMBs actually use - Razorpay, Cashfree, PayU) bundles the gateway with a merchant account so you do not need your own, and handles compliance. A processor is the back-end that moves money between banks. For a small business, you simply sign up with an aggregator and get all of it together.
Most charge a percentage per successful transaction (the MDR), usually around 1.95 to 2% on cards and netbanking, with UPI often free or near-free for merchants under government policy. There is typically no setup or annual fee on standard plans. We break the numbers down in our payment gateway charges guide.
For most Indian businesses the practical choice is between aggregators like Razorpay and Cashfree; see our Razorpay vs Cashfree comparison or browse the payments category. If you just need to get paid fast, see how to accept UPI payments on your website.

Turn this research into a workflow with apps, stages, caveats, and next actions.
Start with the product itself: a place to write and ship code, host it reliably, and catch errors in production, because nothing else matters until customers can actually use what you built. Next, get the team coordinated with project management and a shared knowledge base so work and decisions are not lost in chat. Then put customer acquisition on a real CRM so leads, demos, and deals are tracked rather than living in inboxes. Add billing and accounting once you have paying users, choosing payment rails that fit whether you sell to India, abroad, or both, and keep GST-clean books from day one. Finish with customer support, product analytics, and access security so you can keep users happy, see what they actually do, and not get breached. Do not buy enterprise sales, analytics, and security suites before you have product-market signal; sequence around shipping and getting your first paying customers.

Start by choosing the right no-code platform for what you are building, because a customer-facing web app, a mobile app, and an internal portal each suit different tools. Next, model your data cleanly in a database or spreadsheet backend, since a messy data model is the most common reason no-code projects collapse later. Then build the interface and logic so users have real screens and workflows, not just a database. Add payments, forms, and automations to connect your app to the outside world and remove manual work. Finish by launching, securing team access, and measuring usage so you know the app works and is safe. Do not expect no-code to scale infinitely; it is excellent for validating and running real workflows, but be honest about its ceilings and plan to move to custom code if you outgrow it.

Start by choosing a website builder that matches your skill and needs, because the builder decides how fast you launch and what you can do later. Sort your domain and hosting next, remembering that most builders bundle hosting while self-hosted WordPress needs its own, so you do not pay twice. Then design and write the site so it looks credible and explains clearly what you offer, since a confusing site loses visitors in seconds. Add lead capture, booking, and payment tools so the site actually does something, whether that is collecting enquiries, taking appointments, or selling. Finish by getting found and measuring, with basic SEO, a Google presence, and analytics so you know what is working. Do not over-build a complex site before you have visitors; launch a clear, fast site and improve it with real data.
