I run a busy plumbing-supply shop and need a small web portal that makes every new purchase entry worth more than a line on paper. Here is the flow I have in mind: the counter staff open the site, record the item name and quantity, note the supplier and the exact purchase cost, then hit “Save.” As soon as that happens two things must occur automatically: 1. The system stores the entry so I can search, filter or export it later. 2. A WhatsApp Business message is fired off to a pre-defined contact list—filtered by the product category we’ve tagged—letting customers or team members know fresh stock has arrived. Only the “new purchase entry” event should trigger these notifications; low-stock or scheduled reports are not required right now. I still want the flexibility to group contacts into categories so that, for example, only the ‘PVC Fittings’ customers hear about a PVC delivery, while copper buyers are told about copper. Core screens I expect: • Secure login • Simple purchase entry form (item, supplier, cost, quantity, category tag) • Contact/Category manager for WhatsApp lists • Purchase history table with basic search and date filter • Settings page to edit the WhatsApp template message Tech is up to you—PHP-MySQL, Node-Postgres, or any modern stack is fine as long as it is responsive and can integrate with the official WhatsApp Business API (or a reliable gateway) for bulk messaging at reasonable throughput. Deliverables: • Fully functional, browser-based application hosted on my server • Source code with clear installation instructions • Quick user guide showing purchase entry and WhatsApp blast in action If this matches your skill set, let’s talk timelines and the milestones needed to roll it out smoothly.

Hi, This is a strong fit for a small custom business portal, and we like the fact that the goal is not simply to record purchases but to make each purchase entry immediately useful for stock communication. The workflow we understand is: Staff Login → Enter Purchase Details → Select Product Category → Save → Store Purchase → Identify Matching WhatsApp Contact Group → Send Stock-Arrival Message We also have experience with business portals involving product/inventory management, customer/partner management, reporting and role-based access, which aligns well with the operational side of this requirement. Our questions: 1. Do you already have a WhatsApp Business API provider/account, or would you like us to recommend the most practical option? 2. Will staff manually maintain the customer/contact groups, or do you need an initial import from Excel/CSV? 3. Should the WhatsApp message include only the product name/category, or details such as quantity and supplier as well? Once these are clear, we can map the implementation into practical milestones. We'd also be happy to have a short call to discuss the project together. This will help us remove any assumptions and give you a more accurate timeline for rollout. Regards!

The key requirement is a purchase driven WhatsApp notification system: when staff save a new plumbing purchase, the backend should store it and immediately notify only the contacts matching that product category. I can build this as a Node.js application with PostgreSQL, secure authentication, purchase management, category-based contact groups, searchable purchase history, date filtering, and editable WhatsApp templates. The notification flow will trigger only from the new-purchase event, with the selected category determining the WhatsApp recipient list. For WhatsApp, I can integrate the official WhatsApp Business API or your preferred reliable gateway, with proper error handling and background processing so bulk notifications do not block the purchase operation. I’ll make the interface responsive, deploy it to your server, provide clean source code and installation instructions, and include a short user guide for the complete purchase-to-WhatsApp workflow. Can you provide the WhatsApp Business API access or confirm which gateway you want to use?

You need each purchase entry to become both a searchable stock record and a category-targeted WhatsApp notification, triggered only after a successful save. At Poundit, I built Node.js e-commerce workflows involving product data, automated actions, and PostgreSQL-backed business records. I’d use Node.js and PostgreSQL for a responsive portal with secure login, validated purchase entry, category-based contact management, searchable history, CSV export, and editable message templates. The save operation will record the purchase first, then queue notifications only for opted-in contacts linked to that product category. Delivery status, failures, retries, and message references will be logged so staff can verify exactly what happened. I’ll integrate the official WhatsApp Business Cloud API or an approved provider, accounting for template approval, rate limits, and customer consent. The handover will include source code, deployment instructions, environment-variable setup, and a short user guide. Do you already have a verified Meta Business account and WhatsApp sender number?

Hello, You need a simple purchase portal where **one saved stock entry automatically reaches the right WhatsApp customer group**—without manual follow-up or unnecessary automation. I can build: * Secure login and responsive web UI * Purchase entry: item, supplier, cost, quantity & category * PostgreSQL/MySQL database with searchable history * Date filtering and CSV/Excel export * WhatsApp contact + category management * Category-based customer targeting * Editable WhatsApp message templates * Official WhatsApp Business API integration * Automatic notification only after a new purchase is saved * Settings, validation, error logging and admin controls I’ll keep the architecture lightweight and modular so inventory reports or additional automation can be added later. The **₹1,500–12,500 budget** is suitable for a focused MVP, depending on the WhatsApp API setup and hosting environment. Do you already have a **Meta WhatsApp Business account/API access**, or should I include the integration setup in the milestone? Best regards, Ankit
