You've built your SaaS. The frontend works, authentication is sorted, and your app is finally ready for users.
Now comes the less exciting part: getting paid.
For most indie developers, the first two options are pretty obvious: Stripe and PayPal. They're well-known, customers trust them, and you can find plenty of tutorials for integrating both.
So why would anyone bother looking at crypto payments?
Stripe and PayPal are probably where you should start
If Stripe is available in your country, supports your business, and your customers are happy paying by card, there's usually no reason to complicate things.
Stripe has good developer documentation, subscription billing tools, and a checkout flow that most customers already understand.
PayPal is another reasonable option, especially when customers prefer paying through an account they already use.
But things aren't always that straightforward.
Maybe Stripe doesn't support your business location. Maybe your customers are spread across countries where international card payments aren't particularly convenient. Or maybe you run a digital service and keep getting requests for a payment method other than cards or PayPal.
These aren't problems every developer will encounter, but they're common enough to be worth thinking about.
Where stablecoin payments fit in
This is where USDT and USDC can become useful.
I'm not suggesting that crypto should replace Stripe or PayPal. For most SaaS products, cards are probably still the easiest way for customers to pay.
But if you're selling developer tools, API credits, hosting, or other digital services to an international audience, you might already have customers who hold stablecoins and would prefer spending them directly.
Instead of asking those users to go through another payment method, you can offer USDT or USDC as an additional checkout option.
The interesting question then becomes: how much payment infrastructure do you actually want to build?
You don't need to build a crypto payment system from scratch
The simplest option is putting a wallet address on your website.
That technically works, but it isn't a great checkout experience. You'll need to figure out who sent each payment, whether the amount is correct, which network was used, and when to deliver the product.
For a couple of manual orders, fine. For a SaaS with automated account upgrades or credit purchases, not so much.
A hosted payment link is a better starting point for a small project. You create a payment request, send the customer to a checkout page, and let a payment provider handle supported network options and transaction tracking.
If your app needs automated fulfillment, you'll eventually want an API and webhooks.
For example, imagine selling $10 worth of API credits:
A user selects the $10 package.
Your backend creates an order.
The user is redirected to a hosted checkout.
The payment provider detects and confirms the payment.
Your backend receives and validates a webhook.
Your system marks the order as paid and adds the credits.
The important part is not trusting the checkout redirect alone. You need to verify the payment status server-side and make sure processing the same webhook twice doesn't credit the user twice.
You'll also need to think about underpayments, expired orders, refunds, and payments sent on the wrong network.
Not exactly glamorous work, but neither is debugging a customer's missing credits at 2 AM.
Would I self-host or use a payment provider?
It depends on what you're building.
If payment infrastructure is a core part of your product, self-hosting and monitoring blockchain transactions directly may be worth the effort.
If you're working on a small SaaS, though, I'd rather spend that time building features people actually want.
There are hosted services that handle the checkout and payment notifications for you. One example is JangoPay, which I work on. It offers stablecoin payment links and API/webhook integration for online merchants.
Regardless of the provider, I'd compare documentation, supported networks, fees, settlement, refund handling, and what happens when a payment goes wrong.
And of course, accepting crypto doesn't remove your responsibility to follow payment regulations or your provider's business restrictions.
My takeaway
I'd still start with Stripe or PayPal for most indie projects. They're familiar, widely used, and good enough for a lot of businesses.
But if customers are asking for alternative payment methods, stablecoins are worth considering as an additional option.
Start with the payment method your customers actually want. Add the complexity only when there's a reason to.
For those running a small SaaS or developer tool, are you sticking with Stripe/PayPal, or have customers started asking you for crypto payments?
