CellSell® - Retail ERP Platform for Cell Phone Stores

Why CellSell? 

CellSell is an award-winning retail ERP platform designed for cellular phone, wireless device, and telecom retailers. CellSell features a seamless integration of multi-carrier activations, POS cross-selling, real-time perpetual inventory, store and sales rep commissions, mobile device repair ticketing, and an automated streamlined accrual accounting system that delivers lower operating costs and higher profits. The entire system is specifically designed for people who have no experience or knowledge in accounting. It simplifies everyday operations and saves cellular phone, wireless device, and telecom business owners, thousands of dollars in labor costs and professional fees per year.


CellSell provides your telecom business with rapid ROI

CellSell is the first true retail ERP platform designed specifically for cellular phone, wireless device and telecom retailers. Because finance and accounting are built-in, CellSell is fundamentally more comprehensive, cost-effective, and easy to use, and provides more data integrity, data duplication prevention, and a higher ROI than any combination of standalone Cell Phone Store POS Software and Small Business Accounting Solutions, or  disparate Point-of-Sale Solutions for Telecom Retail alongside any multi-purpose Bookkeeping Systems that you may already be familiar with.


CellSell simplifies all of your complex telecom retail carrier point-of-sale transactions

With less screens to navigate for the processing of complex telecom retail carrier POS transactions than other systems, CellSell makes checkouts at the till simple, fast, easy, and accurate. This increases the number of wireless device orders that can be closed per hour by your sales team, which significantly improves your in-store customer experience. CellSell also accurately classifies your carrier commission revenue from these transactions in real-time, making it possible to track and electronically reconcile each one of them,  more easily and precisely, than ever before.


CellSell is the one source of financial truth for your telecom business

CellSell eliminates the need to manually enter, export, synchronize, reconcile sales receipts, taxes, general ledger, and inventory data between disparate POS and accounting systems.  CellSell accurately combines your POS transaction data with your accounting data in real-time, ensuring the dependability, timeliness, and clarity of your financial information and providing you with a single source of financial truth for your business.
