Lin4V

Lin4V is a business management, sales, and operations application designed for stores, branch chains, and sales teams that need to track data in real time. The solution focuses on digitizing the entire process from data entry, inventory control, invoice creation, to internal personnel management, helping businesses reduce manual errors and increase daily operational efficiency.

With its inventory management module, Lin4V supports tracking inventory levels by branch, provides quick inventory updates, categorizes products by category, and alerts for low inventory levels to proactively plan restocking. Businesses can centrally manage product catalogs, standardize product data, and clearly control sales/discontinuation status within a single system.

In invoice management, the application allows for creating new invoices, searching, and filtering by time, branch, and customer; it also supports transaction notes, payment status tracking, and attaching invoice images via camera or image library. This feature is particularly suitable for retail models that require fast order processing, complete transaction proof storage, and easy reconciliation.

With its customer management module (basic CRM), Lin4V stores customer information, purchase history, customer sources, feedback, and invoice linking, allowing the customer service team to track the customer journey more effectively. Centralized data helps improve service quality, increase return rates, and optimize sales operations based on target customer groups.

Lin4V also integrates internal operational management features such as user role management (admin, manager, employee), leave request management, payment voucher management, and monitoring of overall metrics via dashboard. The permission system helps businesses control operations according to each position's responsibilities, enhancing security and transparency of data across the entire system.

Thanks to its intuitive interface, fast operation, and structure tailored to the realities of Vietnamese businesses, Lin4V is a suitable choice for inventory management, sales management, invoice management, customer management, branch management, and business operations management on mobile devices. The application helps managers grasp business situations faster, make more accurate decisions, and build professional and sustainable workflows.
