I need a custom billing solution that works like Vyapar but is tailored to my workflow. The core of the project is straightforward: create an intuitive invoicing system that handles inventory management, performs accurate GST calculations on every transaction, and supports multiple user access so my team can work simultaneously without hiccups. Beyond the billing engine itself, I want the software to sit comfortably in my current tech stack. It must exchange data seamlessly with my accounting software, feed customer information to my CRM, and process payments through popular gateways. If you have ready-made connectors, great—otherwise we’ll map out the APIs together. What I expect from you: • An installable, production-ready application with clean UI/UX. • Inventory, GST, and multi-user modules fully tested. • Stable integrations with the accounting package, CRM, and at least one mainstream payment gateway. • Source code, build instructions, and brief user documentation. If you have experience building GST-compliant billing tools for the Indian market—or have already tackled Vyapar-style projects—let’s discuss timelines and milestone check demo [login to view URL]

Hi, Went through your requirements for the Vyapar-type billing software. GST compliant invoicing with inventory, multi-user access and integrations - this is exactly what we have built before for Indian SMEs. Your scope is clear: - Invoicing with GST calculations - Inventory management - Multi-user access - Integration with accounting software, CRM and payment gateways Checked the demo you shared. Clean interface. We can build something similar with MERN stack. Few questions: - What accounting software are you currently using? Tally, Zoho Books? - Which CRM do you need to integrate with? - Preferred payment gateway - Razorpay, PayU? - Do you need mobile app as well or just web? - How many users will be accessing simultaneously? Let me know. Happy to discuss approach and timeline. Raj

The requirement for a Vyapar-like invoicing system that integrates tightly with existing accounting software, CRM, and payment gateways indicates a complex, multi-module project needing seamless interoperability. I approach projects like this by maintaining clear structure and consistent communication to ensure steady progress and aligned expectations. When integrations are involved, I prioritize confirming scope and data workflows before firming up schedules or costs, to avoid surprises and keep delivery smooth. Though new to Freelancer, I’ve successfully completed similar GST-compliant billing solutions for clients elsewhere, focusing on usability and stable integration. Which integration or module do you consider most critical to get right during initial development? Cheers, Ryan
