Hi there, I will integrate Stripe subscription management into your Base44 app — billing plans, trial periods, and a customer portal for managing active subscriptions. One thing I will configure upfront: Stripe webhook listeners for events like `customer.subscription.trial_will_end` and `invoice.payment_failed`. This ensures your app reacts in real time — sending reminders before trials expire and handling failed payments with automated retry logic instead of silently losing subscribers. Questions: 1) How many subscription tiers do you need, and will they differ by features, usage limits, or both? 2) What is the free trial duration, and should users provide a payment method upfront to start it? Looking forward to talking through the details. Kamran

I can integrate Stripe’s subscription system into your Base44 app, including handling subscriptions and setting up free trials for new users. In a previous project, I helped a SaaS client streamline their subscription flow with Stripe, which included trial periods and automated renewals. This improved their signup conversion and reduced payment issues. To make sure the integration goes smoothly, would you prefer trial periods to be fixed length or customizable per plan? Also, do you want subscription status synced in real time within Base44 for immediate access control? This is a common integration and can be completed quickly with a clear plan. I’m ready to start setting up the subscription logic and trial management for your app.

Integrating Stripe subscriptions into a Base44 app with free trials is mostly about getting the lifecycle right from checkout through webhooks rather than just creating a payment flow. I’d start by defining your Stripe products and prices, then set up Checkout Sessions with trial_period_days so new users can onboard without payment friction. After that, I’d wire up webhooks to keep Base44 in sync—handling events like subscription created, updated, canceled, and invoice payment failures. On the backend, I’d store a minimal subscription state tied to your user model and gate features accordingly. I’d also add Stripe Customer Portal so users can manage upgrades or cancellations without support overhead. Edge cases like failed renewals or trial expiration need clear fallback states and notifications so users don’t get locked out unexpectedly. Happy to get this running cleanly in your stack.

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have integrated Stripe subscription management with free trial setups for SaaS platforms before, enabling seamless subscription lifecycle handling. From my experience, the most important part to successfully complete this project is ensuring smooth synchronization between Stripe subscription statuses and the app’s user management. Approach: ⭕ Analyze Base44 app architecture and current payment flow ⭕ Implement Stripe subscription API integration with trial period support ⭕ Ensure real-time subscription status updates and error handling ⭕ Test thoroughly across all user scenarios in Base44 ❓ Could you clarify the current onboarding flow and how subscriptions are tracked in Base44? ❓ Do you have any specific trial duration or subscription plans defined? I am confident in delivering a robust Stripe subscription integration tailored for your Base44 app with clean, maintainable code. Looking forward to working together. Best regards, Nam

Hi, I can help you You want people to sign up in your app, start on a free trial, then switch to a paid plan, all handled by Stripe. New users should be billed the right amount at the right time, and you need an easy way to see and manage their plans and status. This will take a few days, I've been doing this type of work for years. I have short walkthrough videos on my Freelancer profile showing similar work. 1) What parts of Stripe are already set up, if any, and what exists in Base44 today for users and plans? 2) What should the final flow look like from sign up to trial to paid, and which plans and trial length do you want? Ideally, we have a call and go through the details together so I can make sure I understand everything correctly, address any questions, and give you a quote and timeline. Would that work?

Hi! Stripe subscriptions need to be wired carefully so trials, renewals, and status changes all stay in sync with your app. I can integrate Stripe’s subscription system into your Base44 app so new users get a smooth free trial, and paid plans are managed automatically without manual work. I’ll handle plan setup, webhook handling, trial logic, and make sure your app always knows whether a user is active, in trial, past due, or cancelled. The code will be clean and easy to extend if you add more plans later. I’ve worked on similar Stripe subscription setups where trials and lifecycle events were critical to user access control. Do you already have the Stripe products and prices created, or should I set that up as part of the integration?
