Base44 Stripe Integration: Understanding Capabilities and Production Limitations

"I finally got payments working in my Base44 app! Upgraded to Builder tier, connected Stripe, and watched my first test subscription go through. I was so excited... until Monday morning when I checked my dashboard and realized none of my weekend renewals had processed. Turns out, they only work when users are actively logged in."

Here's the thing nobody tells you about Base44 payments: yes, they exist. Yes, you can absolutely integrate Stripe through the Builder tier. You'll get backend functions, webhook endpoints, the whole nine yards. But there's a catch that'll bite you the moment you try to scale past your first few customers.

Base44's webhooks only fire when someone's actively using your app. Subscription renewal at 3am? Nope. Failed payment retry while your customer's at lunch? Not happening. Any billing event that needs to run in the background when users aren't logged in? That's where Base44's session-based architecture hits a wall.

Here's what you've probably already built: a gorgeous pricing page, a smooth checkout flow, maybe even a user dashboard with billing info. Base44's Builder tier can handle the UI and basic payment processing. What it can't handle is running your billing operations 24/7 in the background like a real SaaS needs to.

Wait, So Base44 CAN Handle Payments?

Let's clear this up because there's a lot of confusion out there. Yes, Base44 absolutely has payment capabilities. You're not stuck with a frontend-only app. The Builder tier (starts at $20/month) gives you real backend functions, actual Stripe integration, and legitimate webhook endpoints.

What You Can Actually Build with Base44 Builder

✅ One-time purchases (sell credits, products, whatever)
✅ Monthly or annual subscriptions
✅ Full Stripe Checkout flow (the fancy hosted page)
✅ Backend API endpoints that talk to Stripe
✅ Webhook listeners for payment events
✅ Basic subscription status checks

If you're building something simple—maybe a side project charging $10/month to a handful of users who check in regularly—Base44 might be all you need. Seriously. No shame in that. But if you're trying to build a real business with hundreds of customers, automated billing, and the expectation that things work whether users are online or not... that's where we need to talk about what breaks.

The Three Problems That'll Eventually Bite You

Alright, so you've got payments working. Congrats! But before you start celebrating and planning your exit strategy, let's talk about what happens when your app actually gets traction. These aren't theoretical problems—they're the exact issues that'll wake you up at 2am when customers start complaining.

Problem #1: The "Ghost Webhook" Issue

Picture this: it's Sunday night. Your customer's subscription is set to renew. Stripe processes the payment at midnight. Your webhook fires... and nothing happens. Why? Because your customer is asleep and not logged into your app. Base44's webhooks need an active user session to run. No session, no webhook processing. Your customer paid, but their access doesn't update until they log in Monday morning and trigger a session.

The real damage: Failed payment retries don't work (goodbye revenue recovery). Dunning emails don't send (hello churn). Usage-based billing calculations never run. Any automated billing workflow that depends on webhooks firing 24/7 just... doesn't work. You'll end up manually processing renewals like it's 2005.

Problem #2: You're Renting, Not Owning

That $20/month Builder tier fee? It's not going away. Ever. And as you grow, you're stuck with whatever Base44 offers. Want to customize your webhook logic? Too bad. Need to migrate to AWS because you landed an enterprise customer with compliance requirements? Good luck untangling everything from Base44's platform. You're essentially paying rent on your business's payment infrastructure.

The real damage: Every feature request becomes "can Base44 do this?" instead of "let's build this." Your runway calculations now include a platform fee that scales with your success. And when you inevitably need to migrate (not if, when), you're looking at months of rebuild work.

Problem #3: Enterprise Customers Will Ask Questions You Can't Answer

"What's your SOC2 status?" "Can you handle multi-currency?" "We need custom tax rules for 12 different jurisdictions." "Show us your PCI compliance documentation." These are real questions from real enterprise buyers, and Base44's backend functions just aren't built to handle them. You're not running on enterprise infrastructure—you're running on a platform designed for prototypes.

The real damage: You'll lose enterprise deals because you literally can't meet their compliance requirements. Your payment processing will break when you try to expand internationally. Complex pricing models (usage-based, seat-based, tiered) become engineering nightmares instead of configuration changes.

So... Should You Use Base44 Payments or Not?

Look, I'm not here to trash Base44. It's a solid tool for what it's designed to do. The question is: does what you're building match what Base44 can handle? Here's the honest assessment of when Base44 works and when you need something more robust:

Scenario	Base44 Builder Works	Need Custom Infrastructure
Customer Base	< 100 active users	> 100 users or enterprise
Subscription Type	Simple monthly/annual	Usage-based, seat-based, tiered
Payment Events	Users logged in at renewal	Background/async processing needed
Failed Payments	Manual retry acceptable	Automated dunning required
Multi-Tenant	Single tenant/user	Organization/team billing
Compliance	Basic PCI (Stripe handles)	SOC2, custom tax, audit trails

Here's the TL;DR: If your entire billing model depends on things happening automatically in the background (renewals, dunning, usage tracking), Base44 won't cut it. Doesn't matter if you have 10 customers or 1000—if you need webhooks firing 24/7 without users being logged in, you're going to need real backend infrastructure. The Builder tier gets you started, but it won't get you to scale.

The Production Payment Architecture

Here's what a proper payment implementation for your Base44 app actually looks like:

Complete Payment Stack:

1. Secure Backend API

Server-side endpoints that safely store Stripe keys and handle payment operations

2. Stripe Checkout Integration

Redirect-based checkout that keeps sensitive data off your servers

3. Webhook Handler

Endpoints that receive and process Stripe events in real-time

4. Database Integration

Persistent storage linking users to subscriptions and payment history

5. Access Control Logic

Rules that grant/revoke features based on subscription status

Subscription vs. One-Time Payments: Choosing Your Model

Different business models require different payment architectures. Here's what each involves:

Feature	One-Time Payments	Subscriptions
Complexity	Simpler implementation	More complex lifecycle
Webhooks Needed	3-5 event types	10+ event types
Failed Payment Handling	Simple retry or fail	Dunning, grace periods, notifications
User Access Logic	Binary: paid or not	Tier-based, usage limits, feature flags
Tax Handling	Per transaction	Ongoing compliance, reporting

Pro Tip: If you're building a SaaS, start with Stripe Checkout for subscriptions. It handles the complex UI, 3D Secure authentication, and mobile optimization – you just need the backend to create checkout sessions and process webhooks.

Essential Webhook Events You Must Handle

Webhooks are the backbone of reliable payment processing. Missing even one critical event can break your billing system:

Checkout & Payment Events

checkout.session.completed
payment_intent.succeeded
payment_intent.payment_failed
charge.refunded

Subscription Events

customer.subscription.created
customer.subscription.updated
customer.subscription.deleted
invoice.payment_failed

Tax Compliance: Don't Ignore This

If you're selling to customers in different states or countries, tax compliance isn't optional. Here's what production payment systems need:

Tax Requirements for SaaS:

US Sales Tax: Economic nexus rules vary by state – you may owe tax in states where you have customers
EU VAT: Required to collect and remit VAT for EU customers, with proper invoicing
Stripe Tax: Can automate calculation and collection, but requires proper integration
Tax Reporting: Annual 1099-K reporting for US businesses
Invoice Requirements: Many jurisdictions require specific invoice formats

Common Payment Integration Mistakes

Mistake #1: Not Handling Failed Payments

Credit cards expire, get declined, or hit limits. Without proper dunning (retry logic), you'll lose paying customers to preventable churn.

Solution: Implement Smart Retries and send customer notifications for payment issues

Mistake #2: Trusting Frontend Data

Never trust prices or subscription details passed from the frontend. Malicious users can modify JavaScript to pay less or get premium features.

Solution: Always look up prices and products server-side using Stripe's API

Mistake #3: Ignoring Webhook Verification

Without signature verification, attackers can fake webhook events to grant themselves free access or trigger fraudulent refunds.

Solution: Always verify webhook signatures using Stripe's signing secret

Frequently Asked Questions

Can Base44 handle Stripe payments?

Short answer: yes. Long answer: yes, but with some important caveats. Base44's Builder tier ($20/mo) gives you legit Stripe integration—you can do one-time purchases, subscriptions, the full Stripe Checkout flow. It works! But here's where it gets tricky: webhooks only fire when users are logged in. So if you need automated subscription renewals at 3am, or failed payment retries throughout the day, or usage-based billing calculations running in the background... those won't work. Base44 is great for simple payment scenarios where users are actively engaged. For production SaaS that needs 24/7 automated billing operations, you'll hit the ceiling pretty quick.

Can I use Stripe Elements directly in Base44?

You can use Stripe Elements for the card input UI, but you still need a backend to create payment intents and handle webhooks. The frontend-only approach creates security vulnerabilities.

How much does payment integration typically cost?

Professional payment integration for Base44 apps starts around $3-5K for one-time payments, $5-8K for subscriptions with full lifecycle management. This includes the backend, webhooks, and database integration.

What about PayPal or other payment providers?

Stripe is recommended for most SaaS applications due to its developer experience and subscription features. PayPal can be added as an additional option if your market demands it.

Do I need to be PCI compliant?

Using Stripe Checkout or Elements means Stripe handles PCI compliance for card data. However, you still need secure backend practices for API keys, user data, and webhook handling.
