Payment Processing Jobs

I need to add end-to-end payments processing to my application so that customers can complete financial transactions without ever leaving the platform. The core work involves choosing and integrating a mainstream gateway (Stripe, PayPal, Adyen or a comparable API), wiring up the server-side logic, and exposing clean client-side calls that handle tokenisation, 3-D Secure flows, refunds and recurring charges where relevant. The codebase is currently built in Node.js with a React front end, so familiarity with this stack, REST/GraphQL, and typical PCI-DSS best practices is important. I already have merchant accounts in place; what I am missing is the glue that turns an order into a confirmed, securely captured payment and stores the resulting transaction metadata in my PostgreSQL database....

I’m putting together a cross-platform billing and inventory SaaS that must run smoothly on the web (React) and mobile (Flutter). The core stack is already chosen: a Django backend with a PostgreSQL database, all deployed on AWS. Key functional blocks you’ll build and wire up: • Subscription engine – monthly recurring plans driven by Razorpay Subscriptions API, with optional Stripe fallback, automatic invoicing, proration, and dunning logic. • GST-compliant invoice management – create, edit, email, and share invoices; integrate with the GSTN e-invoicing APIs for real-time IRN and QR code generation. • Inventory & batch tracking – receive stock, monitor quantities, lot/expiry dates, and link sales orders to inventory reductions. &bul...

The task is simple: pay BDT 2,640 for a small digital product through your own bKash wallet as soon as I share the link. I will forward the exact URL and short step-by-step notes right after the project is awarded, so you know the item, amount and reference to enter. The whole process should take no more than 30 minutes. I cover the purchase cost through your wallet; you receive US $40 here on Freelancer once the payment is confirmed. Because I prefer bKash, please make sure your wallet is active with enough balance. If you also happen to have Nagad or Rocket, that is fine, but bKash will keep things fastest. Deliverables (all digital): • Screenshot or PDF of the completed bKash transaction showing amount, time, and reference • Any confirmation page or e-mail the site issues...

My Shopify store is live but none of the core apps are wired up yet. I’m looking for someone who can jump in, connect the payment gateways, fine-tune the checkout flow, and make sure visitors immediately see genuine reviews and confidence-boosting trust badges. Here’s what I need done: • Payment gateway integration – I’m open to PayPal, Stripe, Square, or the solution you recommend; the goal is a seamless, test-verified transaction from cart to confirmation email. • Checkout page polish – tweak the layout, add any extra fields we decide on, and style everything so the colours, fonts, and button shapes match the rest of the brand. • Reviews import or creation – set up an app like , Loox, Yotpo (or your preferred tool), import existing...

I frequently spot great deals on leboncoin, vinted and a handful of other local French marketplaces, but most sellers will not ship outside France. I’m looking for a reliable partner based in France who can step in for the purchase and international forwarding only—I’ll handle all the searching and send you direct links to each listing. Here’s how I’d like the workflow to look • I send you the item link along with my maximum bid or “buy-it-now” budget. • You confirm current price and availability, buy the item, and hold it until everything in the batch is ready. • Once I fund the total (item cost + your service fee + postage), you pack the goods securely and dispatch them to my address in India with tracking. Any mainstream co...

I’m building an Android-only application that lets customers book our home-service offerings in three quick steps: pick a service, choose an available time slot, and secure it with a PayPal deposit. I’ll supply the detailed business rules that govern which technicians are available when, along with all exception logic. The core build needs to cover: • Real-time slot calculation based on the rules I provide • Secure PayPal deposit collection and confirmation • Two-way calendar sync (Google Calendar preferred) so my team’s schedules update automatically • Push and/or SMS reminders for both customers and staff • A straightforward cancellation flow that triggers our refund policy logic • A lightweight dashboard where the team can view,...

I’m preparing to launch a multi-country marketplace and need an expert to validate how we should wire everything together in Stripe. My top priority is getting payments and payment security right, so I want a seasoned professional who already knows the quirks of Stripe Connect, Stripe Identity, and the wider ecosystem of webhooks, restricted keys, and sandbox testing. Your first assignment is straightforward: audit Stripe’s current capabilities against our marketplace needs and map out the optimal technical architecture. The architecture must cover these critical workflows: • Payment authorizations • Refunds and disputes • Payout workflows Please ground your recommendations in real-world experience—show me where you’ve implemented similar flo...

Currently, each invoice request requires me to complete several steps. The guest sends me a message or calls me, provides their company details, which I then have to enter manually, locate the relevant reservation, issue the invoice in my invoicing software and send it by email. With seven apartments and a high number of bookings, this results in many additional tasks every month, while manually entering the information creates a risk of errors in the tax identification number, company name or address. My idea is to fully automate this process. The guest scans a QR code placed in the apartment, completes a short form and confirms the information using a link received by email. The system then automatically issues the invoice in invoicing software such as inFakt and sends it to the specifi...

My business-critical Facebook ad account was suddenly restricted for “Payment issues” while I was paying with a credit card. I have not opened any support ticket or chat with Meta yet, so the account is still in its initial locked state. What I need now is a specialist who already knows the ins-and-outs of Meta Business Manager, policy escalations, and the right wording for payment-related appeals. You will take the lead on contacting Facebook support, preparing all required documentation, and following through until the account is fully reactivated and able to spend again.

I need a seasoned WordPress developer to take full ownership of an Islamic consultancy and e-learning site that is already conceptualised but not yet built. The platform’s core purpose is to deliver consultancy services, so the user journey must centre on an intuitive online booking calendar.

My WordPress limousine site already performs well, but the Wine Tour page suffers from Rezdy’s clunky functionality. I want to keep every other part of the site exactly as it is and simply swap the current booking widget for a clean Shopify checkout experience. Here is the flow I have in mind: • Each tour date will live in Shopify as its own product; stock levels will mirror the number of seats in the vehicle. • A booking-button or custom JS SDK embed should appear in place of the existing Rezdy section on the WordPress Wine Tour page. Customers must be able to select their date, pay, and receive confirmation without ever leaving my domain. • Design should inherit my site’s styling so the transition feels native. • All back-end reporting must remain i...

This app is for a car-hire business where the app needs to handle both invoicing and staff rostering, I’d think of it less as a simple car-booking app and more as an operations management app. Core app concept A central dashboard that connects: Customer → Booking → Vehicle → Driver/Staff → Job → Invoice → Payment That way, information only needs to be entered once.

Rostering * Calendar view of all drivers/staff * Drag-and-drop shifts * Assign driv...

I need a complete ride-sharing solution released as native-quality iOS and Android apps plus a responsive web portal. The system must cover secure user registration and login, real-time GPS ride tracking, and seamless in-app payment processing.

I’m ready to move my existing mobile app to the next stage by introducing two key capabilities: secure email-and-password sign-up/login and a fully functioning in-app purchase flow. The current build is stable but still lacks these revenue-driving and user-management features, so I’d like to fold them in without disrupting what already works. Scope • Implement robust user authentication based strictly on email and password, complete with validation, forgotten-password flow, and token-based session handling. • Integrate in-app purchases (consumables and/or subscriptions, depending on what the store guidelines permit) so that purchases are processed, verified, and recorded on the backend. • Refactor or patch any surrounding code that these features touch to ...

I need an experienced Meta (Facebook) ads specialist to step into my current Ads Manager account and sort out a persistent billing and payment problem that is preventing my campaigns from running.

I’m looking for someone who can handle the full setup of a brand-new Wise account for me and have a debit card issued on it. I don’t have an existing profile, so this starts from scratch: opening the account, completing any identity verification Wise requires, and ensuring that the card is linked to a USD balance.

I need accurate, same-day Tally Prime data entry for my small business so every figure in our books mirrors the reality of our bank and cash positions. The work centres on three concrete areas: • Ledger management – creating, updating and aligning all ledgers with our chart of accounts. • Journal, payment, receipt and contra entries – posting each transaction with the right narration and tax codes. • Expense classification and fresh ledger creation – grouping costs logically and opening any new heads that surface. Please post everything directly inside our existing Tally Prime data file, observe GST and TDS rules already configured and keep audit trails intact.

I need a new WordPress website that lets customers schedule car-cleaning appointments and pay online.

I need a developer who can connect my existing PHP site to a reliable payment gateway. The goal is to give customers a smooth, secure checkout experience from start to finish. I am currently leaning toward well-known services such as PayPal, Stripe, or Square, but I am open to your recommendation if another platform would suit the codebase better. You will be working with a live production environment, so clean, well-documented code and clear hand-off notes are essential. If you have prior experience handling tokenization, secure storage of credentials, and sandbox/live environment switching in PHP, that will help us move quickly. Once the integration is complete I’ll run a few test transactions; as long as those settle correctly and the confirmation callbacks reach my applicat...
