Payment link software and checkout page source code
Payment link software lets you take money without building a store — you create a link or a hosted checkout page for a product, a service or a subscription, share it in WhatsApp, an email or a bio, and the buyer pays on a page you control, with the order recorded in your own database.
Written by ZoopCoder, who build and sell one of the packages described below — that bias is declared in full further down this page.
Quick answers
How much does payment link software cost?
About $30 to $250 as source code you host once, against 2% to 5% of every transaction on hosted link services — some of which take a platform cut on top of the gateway fee. On any meaningful volume the percentage is the dominant cost.
Why not just use Stripe or Razorpay payment links?
Use them if a bare link is all you need. Buy software when you want your own domain and branding, digital delivery after payment, your own customer records, multiple gateways behind one page, or the ability to resell the capability to other businesses.
Can payment links handle subscriptions?
The good ones can, and it is the main quality divide. A subscription link has to create a mandate or a recurring plan at the gateway, then track renewals, failures and cancellations — not just charge once and email a receipt.
The one decision that matters: your own checkout or your gateway’s
Be honest about why you are not just using the payment links your gateway already gives you free. Stripe, Razorpay, PayPal and most others generate links from their dashboard at no extra cost. Buying software is the right call for specific reasons, and if none of them apply you should save the money.
| Approach | Cost | You get | You give up |
|---|---|---|---|
| Gateway’s built-in links | Free, beyond normal gateway fees | Working links in five minutes, hosted and maintained by them | Their branding and domain, one gateway only, no digital delivery, limited data |
| Hosted link platform | Monthly fee, or 2–5% per transaction | Nicer pages, digital delivery, some analytics | A cut of every sale, forever; their platform holds your customer list |
| Self-hosted source code | One-time licence plus a small server | Your domain, your database, several gateways, delivery, and resale rights | You run it, patch it and own PCI scope decisions |
A quick test on any demo: pay a link with the test gateway, then close the browser at the exact moment the gateway redirects back. A correctly built product still records the order and still delivers the file, because it relies on the gateway’s server-to-server webhook rather than on the buyer’s browser completing the round trip. If the order is missing, every dropped connection will become a support ticket about money.
What a complete payment-link package must include
Creating a link is trivial. Everything below is what separates a product you can charge for from a form with a pay button.
- Link types that are genuinely distinct: fixed price, buyer-enters-amount, quantity-based, and recurring subscription
- Webhook-driven order confirmation, idempotent and signature-verified, so a closed browser never loses a payment
- Digital delivery after payment — expiring download links, download-count limits, and files stored outside the web root
- Multiple gateways side by side, with per-link or per-currency routing and a clean abstraction so adding one is not a rewrite
- Custom fields on the checkout page, captured against the order (buyer name, GST number, event date, whatever you sell needs)
- Coupons, tax rules, and a tax identifier field where your jurisdiction requires it on the receipt
- Refunds initiated from your admin, reflected in the order record, with the gateway reference stored
- A customer view of past orders, receipts, downloads and — for subscriptions — a self-serve cancel
- Subscription lifecycle done properly: mandate creation, renewal tracking, failed-payment retries, cancellation and expiry
- If multi-tenant: per-account plan limits, each merchant’s own gateway keys stored encrypted, and subscription billing for them
What payment link software actually costs
The licence is trivial next to the percentages. The number that decides this category is what fraction of each sale leaves the business.
| Route | Typical cost | What you get | Time to live |
|---|---|---|---|
| Gateway built-in links | Free + gateway fee (about 2–3%) | A hosted link on their domain | Minutes |
| Hosted link platform | 2–5% per transaction, or $19–$99/month | Branded pages, delivery, analytics | Same day |
| Marketplace script | $29–$79 | Link creation and one gateway; webhooks often missing | Days — then the reliability work is yours |
| Direct vendor, complete platform | $99–$249 | Subscriptions, delivery, multi-gateway, tenant billing | About a day to deploy |
The arithmetic: at ₹5,00,000 a month in sales, a 3% platform cut on top of gateway fees is ₹15,000 every month — roughly a hundred times a one-time licence, every year. Against that, self-hosting means you carry uptime: a checkout page that is down is revenue that does not arrive, so put it on a host you trust and monitor it. Keep PCI scope narrow by always redirecting to the gateway’s hosted page or using its embedded element, and never letting card numbers touch your server — any script that asks you to accept raw card fields should be rejected outright.
Where to buy, and what each source is good for
| Source | Best for | Watch out for |
|---|---|---|
| Your existing gateway | Anyone who just needs to get paid this week | Their branding, one gateway, and no digital delivery |
| General code marketplaces | Cheap single-user link tools | Order confirmation driven by the browser redirect instead of a webhook — the defining bug of this category |
| Open source | Simple checkout pages you will extend | Subscriptions and multi-gateway routing are rarely finished |
| Direct from the developer | Selling the capability on to other businesses under your own brand | Ask how each merchant’s gateway keys are stored, and test the closed-browser payment before you buy |
Declared bias: what we sell
We are ZoopCoder. We build and sell LinkPay — a payment-link and hosted-checkout platform with one-off and subscription links, digital-file delivery, coupons, a customer portal and multi-tenant plan billing — as source code from $149, with no recurring fee to us. So read this page knowing we are a vendor in the category we just described. Everything above is what we would check if we were buying rather than selling, including the parts that do not favour us: if your requirements are genuinely unusual a custom build beats every package here, and if you want zero operational responsibility a hosted service is simpler than any source code.
If you want a working example to measure against
The LinkPay demo runs the full stack, so you can use it as a yardstick for anything else you are evaluating — including the tests described on this page.
If you are comparing against hosted tools
The economics flip based on scale and headcount. These pages lay out the arithmetic against the hosted platforms most buyers weigh up.
Frequently asked questions
What is a payment link and how does it work?
A payment link is a URL that opens a checkout page for a specific product, service or amount. You create it once, share it by WhatsApp, email, SMS or a social bio, and the buyer pays on that page without you building a store or sending an invoice. Behind it, the gateway confirms the payment to your server by webhook, which is what records the order and triggers delivery or access.
Are payment links safe for the buyer?
They are as safe as the checkout behind them, so judge it on three things. Card details should be entered on the gateway's own hosted page or its embedded element rather than on the seller's server, the page must be served over HTTPS, and the merchant name on the bank statement should be recognisable. Software that asks you to collect raw card numbers yourself puts you inside PCI scope and should be avoided.
Can I sell digital products with payment links?
Yes, and it is the most common use of this software. After the gateway confirms payment, the system emails an expiring download link, typically limited by time and download count, with the file stored outside the web root so it cannot be fetched directly. Check that delivery is triggered by the webhook rather than by the buyer landing on a thank-you page, or a closed browser will mean a paid customer with no file.
What is the difference between a payment link and a payment gateway?
The gateway is the financial infrastructure that actually moves the money, such as Stripe, Razorpay or PayPal. Payment link software is the layer on top that creates the shareable page, captures buyer details, records the order and delivers what was bought. You always need a gateway; link software decides who owns the checkout experience and the customer data.
Can payment links be used for recurring subscriptions?
Yes, when the software creates a mandate or recurring plan at the gateway instead of taking a single charge. That is the feature to verify first, because a subscription link has to track renewals, retry failed payments, expose a cancel option to the customer and handle expiry. Test it in the demo by subscribing and then cancelling, and check the record ends in the right state.
Do I need a business account to accept payments online?
In practice, yes. Payment gateways require merchant onboarding with business identity documents, a bank account and usually a website or app describing what you sell, and requirements vary by country and by the category you trade in. Complete onboarding before you commit to a launch date, because gateway approval is the most common cause of a delayed first sale.
