ACID is cloud-based, which means you don’t have to buy or maintain any expensive back-office servers or software. If you are in Texas, we are local to you, but we also remotely manage and update your system with the latest features and functionality. With ACID you always have industry-leading service and support.
Our retail point of sale system works with Worldpay, Fiserv, BridgePay, and over 80 other merchant processors and gateways. We have the lowest processing fees, value-priced equipment, and the best monthly cost of ownership.
Many customers are requesting home delivery these days, and love being able to order from local stores for speed and convenience. ACID POS supports many choices for shipping with established carriers but also includes delivery functionality that streamlines using your drivers
ACID helps you to manage your delivery drivers with features that allow you to separate them by zip code for the most efficient routing. Drivers can pick up orders from multiple warehouses, locations, and stores. ACID POS cellular tablets even allow drivers to take payments directly from your customers at their doors. The system also works great for in-store or curbside pickup.
Our terminals and tablets all support the latest PCI and PA-DSS standards, unsecured swipes, RFID chipped, Apple Pay, and NFC contactless payments. They also feature a customizable graphical POS system interface and lightning-fast processing that makes transactions a breeze.
With ACID, you can pick from a variety of rugged and elegant hardware options that fit your current business needs. ACID is scalable, so you can get just the terminals you need today and expand as your business grows. The ACID POS terminals feature screen sizes from 16 to 20 inches, customer-facing displays, and cellular-connected tablets you can use anywhere. With ACID, you never pay rental fees on equipment!
Multi-warehouse management is one of the most useful ACID features. You can track your real-time sales and stock at stores, warehouses, and eCommerce sites. ACID lets you add stock, adjust inventory, or transfer merchandise. There are many flexible options for inventory reconciliation to meet your needs. Other POS solutions require expensive third party systems for features we include!
Powerful reporting and recordkeeping are also standard with ACID. Advanced reporting features are customizable, and you always have the data you need at your fingertips.
You can create loyalty rewards or offer automatic VIP discounts as customers reach different levels. ACID supports making discount clubs and loyalty points programs. Coupons, sales, and gift cards are also easy to configure, and they work across all of your stores and websites.
ACID excels at collecting tips and charity gifts. Our donation feature makes it easy for you to raise money for any cause. The tip function allows cashiers or patrons to add gratuities with a variety of customizable options. With both tips and donations, your customers also approve their final charge amount, so there are no disputes.

Is Having an eCommerce Store Good for Your Physical Shop
An eCommerce website is open 24/7 and accessible from all over the world. Being online and having physical store opens your business to a global market.

Should You Collect Charitable Donations?
You’ve probably been at the register at the grocery store and asked if you wanted to contribute money to a charity as you checked out. Maybe you donated, or perhaps you found it was annoying. It might have depended on your mood that day, or possibly the charity was a deciding factor.

Quality Outweighs Volume When Picking a POS
As a savvy small or medium-sized business owner, you know that you can’t outsell the giant mega-store. You build your customer base because you provide excellent service, an enjoyable shopping experience, and a fantastic value.

Choosing the Best POS Software and System
While a free demo or limited version of a POS system might entice some, they soon find out that they have to pay for the features they need.
