PayLink - Invoice and Payment Link Generator Full Solution

PayLink – Invoice and Payment Link Generator Full Solution is a payment collection and invoicing application for entrepreneurs, service providers, startups, and businesses. The package includes Android and iOS applications, a responsive web experience, and an administration panel connected to the same backend.

Users can create products with prices, generate invoices, download invoices as PDF files, send invoice details by email, and create shareable payment links for collecting payments through configured gateways. The system also includes wallet and transaction management, money-out options, multi-currency support, account security tools, notifications, support tickets, and administrative controls.

PayLink is intended for operating your own payment-link and invoicing platform. It is not a downloadable-product delivery system, a payment-gateway aggregator, or a multi-tenant SaaS platform unless those capabilities are added through separate custom development.
