The basics:

Dripos is an all-in-one POS for restaurants. As a direct answer to a common pain point for many restaurant operators — faulty integrations between third-party systems and POS systems — Dripos' capabilities allow you to accept orders from the register, website, app, self-service kiosk and more. The app also includes tools for an in-house delivery system. Once an order is placed, tickets can be managed simply in the KDS or through physical tickets. The program also has tools for staff management, scheduling, payroll, administrative tasks like fulfilling invoices and inventory, and marketing efforts to consumers through email and text message campaigns. 

From the BOH TipJar:

For many restaurants, every dollar counts. Dripos offers an expansive set of features for a flat $149 a month, giving businesses an economically-friendly way to take better control of their finances, staff, marketing, inventory, and more.

In their own words:

Dripos is a point of sale system built for the modern era by restaurant operators around the country. Our customers tried integration after integration with poor results and told us the horror stories of trying to make it all work together. So we made an intuitive app for your POS, mobile orders, marketing, team management, and more. Simple pricing, great support, and a system that just works.
