POS System Companies & Dealers in Supply, NC

Extreme Point of Sale, Inc. is a North Carolina company that writes its own retail checkout software and also provides the equipment needed to operate it. According to Crunchbase, the business was established in November 2000, with Tom Kent listed as both president and founder. It was previously associated with Apex, and its published mailing address is now in Supply, along the state's southeastern coast. For shoppers weighing regional vendors, the firm is best understood as a software developer that doubles as an equipment reseller and help provider, rather than a generalist who installs any system.

Its focus is on independently owned stores, particularly those that purchase, sell, trade and rent pre-owned merchandise. Shops dealing in secondhand items need tracking and reporting features that standard cash registers frequently do not offer. The company's literature describes setups for video game retailers, new and used music, movie and vinyl sellers, repair businesses, book dealers, instrument and music shops, gift boutiques, vape stores, collectible sellers and consignment operations. Selling away from the counter is supported too.

Software and hardware

The main product today is ThunderPOS. It can operate as a Windows-based register paired with a back-office program, as a browser-accessed cloud register, or as a blend of both approaches. Owners may begin with pre-built screen layouts or create their own. Older, niche-specific programs remain part of the company's history: ExtremePOS for game stores, Musicware for disc and record sellers, and Praiz for Christian bookstores. Further options include a register for iPad, tools for chains with several locations that allow inventory to move between stores, and connections to online selling platforms.

For equipment, the firm offers both individual items and pre-assembled packages. Available categories include:

• Full checkout systems sold as packages
• Devices that read product codes
• Printers for customer receipts
• Printers that produce price and product tags
• Money drawers for the counter
• Pole-style screens facing the customer
• Handheld units for stock counting and tracking
• Consumable supplies for the register

Card acceptance is handled by partner processors that connect with the software. The company says it supports major credit brands, tap-to-pay transactions and EMV chip card readers, and it advises interested buyers to talk with its sales staff to be introduced to those partners. It also cautions that purchasers may have to acquire compatible devices.

How they work with customers

People considering the software can try it out and learn it from published tutorials that include screenshots, covering both the Windows program and the online management portal. Subscribers who pay for service can contact the support team by telephone or email on weekdays, Monday through Friday, during business hours. The company says it assists with equipment problems only when the equipment was purchased from it, a point worth noting for anyone intending to use devices acquired elsewhere. Those customers must return to the seller they originally used.

The firm's distinguishing traits are its many years serving a specialized audience and its practice of creating the software in-house, meaning one team manages features, device compatibility and assistance. Its social media account has carried regular product news throughout 2025, including a Stripe payment integration, suggesting ongoing development. Merchants who handle used or traded goods and prefer one provider for software, equipment and help may find it a sensible candidate for their shortlist.
