United States Retail POS Software
Purpose-built for American independent retailers, liquor stores, convenience stores, hardware merchants, and boutique shops seeking freedom from Clover, Toast, and Square. InventoryPlus automates multi-tier State + County + City local district sales taxes, complies with dual pricing and cash discounting mandates to eliminate 3.5% credit card interchange fees, and runs natively on Windows desktop terminals with 100% offline reliability and zero monthly software subscriptions.
Why US Retailers are Escaping Cloud Tablet POS Systems
For years, American small business owners were sold on the promise of sleek iPad terminals. Today, merchants face escalating processing fees, mandatory app-store subscriptions, and catastrophic cloud outages.
Mandatory 2.6% to 3.5% Processing Cuts
Proprietary tablet systems lock merchants into mandatory in-house credit card processing rates of 2.6% + 10¢ to 3.5% per swipe. For a retail store turning $60,000 monthly, that amounts to over $21,000 lost every single year in transaction interchange fees alone.
State, County & Special District Tax Headaches
The United States possesses over 13,000 distinct sales tax jurisdictions. When state rates (e.g., 6.25%), county surtaxes (1.0%), and local city / transit district taxes (0.75%) change, generic POS systems mishandle tax exemptions and trigger severe state Department of Revenue audit penalties.
Cloud Outages & Fragile Consumer Tablets
When cloud servers suffer nationwide outages or local broadband fails during peak holiday shopping, tablet cash registers freeze completely. Overheated iPads, battery bloat, and proprietary locked hardware force retailers into expensive replacement cycles.
The InventoryPlus US Retail POS Architecture
InventoryPlus combines high-speed Windows desktop performance with deep compliance for American retail operations.

Frequently Asked Questions by US Retailers
Clear answers regarding sales tax compliance, dual pricing legality, and hardware integration.
Is dual pricing and credit card surcharging legal in the United States?
Yes. Following federal court rulings and the Durbin Amendment, cash discounting and credit card surcharging are legal across the United States when proper disclosure rules are followed. InventoryPlus adheres to all card brand operating regulations: it clearly itemizes the non-cash adjustment on customer receipts, caps surcharges at statutory limits (maximum 3.0%–4.0%), and ensures debit card transactions are never surcharged.
How does InventoryPlus handle composite state, county, and local sales tax?
You can configure the individual component tax rates for your specific store location. For instance, in California, you can set the California State base tax (6.0%), mandatory local rate (1.25%), county tax (0.25%), and special district transit tax (1.0%), totaling a 8.5% composite rate. When printing customer receipts, the total tax is displayed clearly, while your backend tax liability reports provide the exact breakdown needed for state filing.
Can I use my existing Windows PC, barcode scanner, and cash drawer?
Yes, absolutely. Unlike Clover or Square, InventoryPlus does not require you to purchase proprietary hardware terminals. It runs on any standard desktop PC, laptop, or commercial Windows all-in-one POS terminal (Windows 11, 10, or 7). It communicates directly with standard USB barcode scanners, Epson / Star receipt printers, and RJ12 cash drawers.
What happens if our store internet connection goes down?
Nothing stops. InventoryPlus is an offline-first system powered by a high-speed local database installed directly on your machine. You can scan barcodes, ring up cash and check sales, calculate sales tax, print thermal receipts, and kick cash drawers with zero latency. When your internet connection is restored, transaction logs synchronize seamlessly.
Can we import our existing product catalog from Square or Clover?
Yes. Simply export your product catalog, UPC codes, prices, and customer contact lists from your Square Dashboard or Clover portal into a standard Excel or CSV file. InventoryPlus features an intelligent import mapping wizard that ingests thousands of SKUs and categories in under 10 minutes.
Are there any mandatory monthly subscription fees?
No. InventoryPlus is available under a one-time perpetual lifetime license model. You purchase the software once and own it forever. There are zero mandatory monthly SaaS subscription fees, zero app-store unlock charges, and zero forced processing penalties.
