Hi, Your project to build a custom invoicing and payment platform with web + mobile apps is very interesting, and I’d love to help design and develop a scalable solution for it. I’m a full-stack developer with strong experience in Python/Django, Node.js, React, REST APIs, and payment integrations like Stripe, and I’ve built SaaS systems that include billing, automation workflows, and secure cloud deployments. Relevant Experience: • Built SaaS platforms with subscription billing, Stripe integrations, automated invoices, and financial tracking dashboards. • Developed scalable backend systems with REST APIs, role-based access, and cloud deployments (AWS / Docker). How I’d approach your platform: • Web Admin Portal: Dashboard for invoices, payments, customer data, outstanding balances, and reports. • Mobile Apps (iOS & Android): Cross-platform app (React Native or Flutter) so field staff can create invoices, apply discounts/taxes, and collect payments. • Secure Backend API: RESTful API with proper authentication, database design, and scalable architecture. • Payment Integrations: Stripe, PayPal, and possible bank API with sandbox testing. • Reporting: CSV/PDF exports and payment history tracking. You’ll receive clean, documented source code, deployment support, and a cloud-ready architecture so future features can be added easily. Would you like me to outline an MVP architecture and milestone plan for web, mobile, and backend development? Thanks, Ashish

Hi, I can develop a full-featured invoicing platform with a web portal and cross-platform mobile apps that handle invoice creation, payments, and client notifications. The system will integrate Stripe, PayPal, and local bank APIs, support recurring billing, and provide real-time reports. Questions: Do you prefer the mobile apps built natively (Swift/Kotlin) or via a cross-platform framework like React Native/Flutter? Should the system support multiple currencies and tax rules for different regions?

Hi there, I see you're struggling with jumping between multiple platforms for invoicing, payments, and mobile field operations. I've spent the last 5 years building end‑to‑end billing and payment systems, and I can solve this by developing a unified web portal with cross‑platform mobile apps so your team can generate invoices, apply taxes/discounts, and process Stripe, PayPal, or local bank payments on the spot. I’ll architect a secure RESTful backend, implement PDF generation with your branding, set up automated reminders and recurring billing, and ensure cloud‑ready deployment with clean documentation and full source control. The admin portal will give you clear visibility into balances, payment history, and customer data, plus exportable CSV/PDF reports. Thanks,

Hi there! I noticed your need for a comprehensive Invoicing & Payments App that seamlessly integrates invoicing, payment collection, and client management in one platform.

Could you provide more details on the specific branding requirements for the PDF invoices and the level of customization needed for client notifications? Thanks, Tejbir Bhatia
