I need someone that knows [login to view URL], stripe, and supabase, to help make some changes to the website shown here: www.worldholidaysandevents.com. The website provides information about holidays that are celebrated in countries around the world. It can provide dates for any year. The current system gives the current year information for any country for free, but for future years asks the user to create an account and pay a fixed fee, after which the user is then allowed to make as many queries as they wish. I want to change the current system so that information regarding the current year is free of charge, but for future years a user must create an account and then be charged a fixed amount per query. The login component uses supabase for account validation and the charging component uses stripe. Do you have anyone that can do this? How much would this cost?

We can do it, I will assign a dedicatef dev to do this job. Looking forward to hear from you. Thanks

I can help with this, I will update your billing logic — switching from the current one-time fee to a per-query charge for future-year lookups, adjusting the Stripe integration accordingly, and ensuring Supabase tracks each user's query events. For per-query billing, I will implement Stripe's metered usage approach — logging each future-year request as a usage record and charging against the user's stored payment method. This avoids creating a new checkout session on every query and keeps the experience smooth for repeat users. Questions: 1) What fixed amount per query do you have in mind, and should users pre-load credits or be billed after each request? 2) Is the current Stripe setup using Checkout Sessions or the Payment Intents API? Ready to start whenever you are. Kamran

This looks like a great fit, I will refactor the pricing model so future-year queries charge per query: Stripe Customer + saved payment method, prepaid credit balance in Supabase, queries deduct from balance, low-balance top-up via Stripe Checkout. Current-year stays free. One angle: charging Stripe per query directly hits the $0.30 minimum fee plus 2.9% per tx, unviable below $1/query. Prepaid credit batches into one Stripe transaction per top-up, saving fees and UX friction. Questions: 1) Target per-query price? 2) Existing accounts: migrate to credit balance, or fresh start? 3) Prepaid credit, or metered subscription billed monthly? Looking forward to talking through the details. Faizan

Hi, there. Having read your project description carefully, you aim to modify your e-commerce site to offer current year holidays for free while implementing a query-based charging system for future years. In a previous project, I successfully revamped an existing e-commerce platform by integrating both Stripe and Supabase, enhancing the user experience and ensuring a seamless payment process. Through this project, I can: 1. Revise the current system to align with your updated payment structure. 2. Implement a robust account creation and validation workflow via Supabase. 3. Integrate Stripe for efficient payment processing for future year queries. 4. Ensure a user-friendly interface throughout the entire flow. I communicate promptly with the client throughout the entire development period and deliver excellent results within the deadline. Best, Dmytro

Hello, The real engineering challenges in this project involve adapting the current system's architecture to support a new pricing model while ensuring data integrity. Maintaining secure user sessions and managing billing through Stripe will require careful attention to detail. Additionally, the scalability of query handling for future years must be considered to accommodate potential increases in user traffic. Will the existing Supabase configuration require modifications to support the new account validation process? How do you envision handling user sessions and data consistency during the transition to the new query model? Are there any existing constraints on the API for billing that we need to be aware of? I look forward to discussing the architecture and specifics of your requirements.

I have built per-query Stripe billing on top of Supabase auth before, so this change is a clean fit. For your site, I would update the year check so current year stays free, then gate future years behind a paid query. Each paid query would create a Stripe checkout or charge tied to the user's Supabase account, then unlock that single result. I would also clean up the old fixed-fee unlimited access flow so it does not conflict with the new logic. Fixed price for the full job is 450 USD, with delivery in 4 days after access. One thing worth deciding early is the price per query, since that affects whether we use Stripe Checkout or a saved card with one click charges. I can start as soon as you share repo and Supabase access.

Hey, I am ready when you are.✅ I’ve worked on something very similar. What really matters here is transitioning from free current year info to paid future year queries seamlessly. The tricky part is usually handling account creation, payment processing, and data access control smoothly. I recently worked on a project where I integrated Stripe for payment processing and user authentication using Supabase. While I haven't done this exact setup, I have experience with similar e-commerce site transitions. I'd approach this by first setting up the new payment flow and then integrating it with the existing login system. Let's chat! -Dorofii
