Project Overview

Viva Wireless built a powerful eCommerce platform that supports both retail and wholesale customers. The system includes flexible customer groups, secure admin roles, and a dynamic pricing engine. Features like returns, exchanges, refunds (RMA), PayLater credit, and store wallet options help offer a smooth shopping experience. Wholesale buyers get custom prices and bulk buying tools, while admins manage everything through a clean, role-based dashboard. The platform connects with Amazon, Walmart, and eBay to manage inventory and orders in one place. A custom POS system syncs store sales with online stock in real time. Admins can also import and export products or prices in bulk using CSV files. With strong reporting tools, users can track sales, top products, and customer trends. The system is mobile-optimized, SEO-friendly, and supports multiple secure payment methods, including PayPal, credit cards, and Pay Later. Key challenges included handling over 15,000 products, syncing with marketplaces, and scaling during high-traffic sales. These were solved using phased data migration, smart APIs, and strong fraud checks for PayLater. Load tests and modular admin tools made sure the system runs fast and stays stable, even during peak sales events like Black Friday.

Challenges

Data Migration at Scale
Transferring over 15,000 products and customer records without disrupting the live environment.
Ensuring data integrity, avoiding downtime, and maintaining customer history required careful planning and execution.
Creating a unified admin panel that could handle multiple workflows within a single interface was complex.
Dynamic Pricing Complexity
Applying different price rules for retail and multiple wholesale tiers, while ensuring secure visibility based on customer login.
Synchronizing prices across channels like Amazon, eBay, and Walmart in real time, as each platform has its own format and update frequency.
Managing PayLater services required accurate credit tracking per customer, fraud prevention, and compliance with financial regulations.
Bulk Product Management
Handling bulk product management was demanding, given the scale of over 15,000 SKUs.
Errors in upload or sync could easily affect pricing or availability across channels.
Maintaining data accuracy across the catalog while supporting multiple customer group-specific pricing tiers.
Scalability Under Load
Ensuring fast load times and reliable inventory updates during high-traffic periods like Black Friday.
Smooth order processing under heavy server load while maintaining experience for users and admins alike.

Features Implemented

The Viva Wireless eCommerce platform delivers end-to-end tools for managing retail and wholesale operations, from bulk purchasing to marketplace integration.

1. Bulk Purchase Feature

This feature helps wholesale customers place large orders quickly. Inside a product category, customers can enter quantities using input fields or navigate using the tab key. An "Add Bulk Items" button lets them add all selected products to the cart at once. Admins can set a maximum quantity per item, like 100 units, and also define cart limits. Products are shown in a grid view with quantity selectors, and filters make it easy to select specific items.

2. Product Offers

Admins can create discount campaigns using fixed-amount or percentage-based coupons. These offers can target specific products, categories, customer groups, or entire carts. Offers can run for a fixed time with defined start and end dates. Coupons can be automatically applied at checkout or require a code. Validation rules prevent stacking unless allowed. The admin panel provides tools to create, edit, and monitor offer performance.

3. Pay Later

Viva Wireless offers a PayLater feature that allows customers to purchase products on credit. Admins can assign credit limits based on purchase history or manual approval. This option can be enabled or disabled for specific users or customer groups. Customers can pay their dues in full or in part from their dashboard. The system tracks payment history and sends automated email reminders following a schedule set by the admin.

4. My Wallet

MyWallet allows customers to receive refund credits directly into their account. These credits are issued by the admin after a return and are added to the customer's wallet automatically. Customers can use wallet funds during checkout, with the total applied instantly to reduce their payment amount. The system also works with PayLater, helping offset dues. Wallet activity is clearly visible on the customer dashboard, including transaction logs.

5. Payment Modes

The platform supports a wide range of secure payment options. Customers can pay using PayPal, credit or debit cards, and creditkey. The PayLater option is available for approved users. Popular cards like Visa and MasterCard are accepted. Users can also save payment methods for quicker future checkouts. All transactions are processed through trusted gateways.

6. Multichannel Integration

Viva Wireless integrates with Amazon, Walmart, and eBay to centralize inventory, orders, and pricing. Products are exported to Amazon using UPC or ASIN codes with customer group-specific pricing. Orders are fetched every 15 minutes, and inventory is updated in real time to avoid overselling. A single admin panel manages all marketplace activity. If any sync issues occur, the system shows alerts and logs errors.

Multichannel Integration

7. Return Merchandise Authorization (RMA)

The RMA system makes it easy for customers to request returns. They can choose the reason through a simple frontend interface. The status of the return is tracked in real time. Admins review requests and accept or reject them based on internal policies. The system supports bulk processing, allowing admins to handle returns from multiple users or products at once. Approved returns automatically update the inventory.

8. Point of Sale (POS)

The Viva Wireless POS system is directly integrated with the main platform. It helps manage in-store sales while keeping products, orders, and inventory in sync with the online store. Barcode scanning allows for fast product lookup and easy checkout. The POS accepts payments through cash, credit cards, PayPal, and the PayLater option. As soon as a sale is made in-store, inventory is updated online and across marketplaces.

9. Product Price

Viva Wireless's pricing system helps businesses offer personalized pricing by organizing customers into groups. Each group can have its own price list, making it easy to reflect the value of different customer relationships. Businesses can also set special prices for individual customers, based on contracts or order history. Targeted discounts and promotions can be created for selected groups to boost loyalty and increase sales.

10. Manage Customers

Viva Wireless offers a customer management system that supports both retail and wholesale users. Customers are grouped into categories, such as Retail and Wholesale Tier 1, to give them tailored experiences. Wholesale pricing is hidden from view and only becomes visible after login. Role-based access allows different levels of control, assigned and managed by a super admin. The admin dashboard includes detailed audit logs for all activities.

11. Order Editing and Management

Admins can change orders at any time to meet customer needs. They can add or remove items, update quantities, change shipping or payment methods, and even reassign customer groups. Every change updates the inventory in real time and keeps records in sync. An audit log tracks each edit for transparency. Customers receive automatic email updates whenever a change is made.

12. Bulk Product and Pricing Import/Export

Admins can manage large product catalogs and pricing using structured CSV files. Bulk imports include SKUs, names, descriptions, images, and categories. Pricing updates can be done in bulk, even for customer group-specific pricing. Admins can use dedicated templates and schedule imports using cron jobs. Built-in validations help prevent errors.

13. Advanced Analytics and Reporting

The reporting system gives detailed insights into sales, inventory, and product performance. Admins can view reports by customer group, sales channel, region, or time range. Metrics include top sellers, slow-moving items, gross margin, and profit/loss. Real-time dashboards use visual tools like bar, line, and pie charts. Reports can be exported in CSV or PDF format.
